To perform endoscopy in patients with urinary diversions requires specific endoscopic skills, which can currently only be gained in clinical practice. We created a 3D-printed ex vivo ileal conduit model (stoma and conduit with ureters and 2 kidneys) to simulate "conduitoscopy" and evaluated the realism and limitations of the model. Accurate anatomical features were represented using an appropriate reusable design, realistic mechanical qualities with several material types, and 3D-printed components. Different models of bowel and ureters were assessed by the subject-matter experts (SME). The final ileal conduit model (Wallace 1 type anastomosis) was evaluated by 18 SMEs. Most experts gave their approval to the view of the stoma, as well as the appearance of the bowel, ureteric, and pelvicalyceal systems. A total of 72.1% of SMEs approved the ureteric endoscopic view compared to about 66% who accepted the endoscopic examination of the bowel. The model's overall appearance was good for 61.1% and excellent for 38.8% of experts. Conduitoscopy simulation training can now be facilitated using our novel and unique cutting-edge 3D-printed model. We created a model that is highly anatomically accurate and workable. In our study, anatomical and visual realism was demonstrated. The next step would be increasing the length of the conduit and conduct a validation study. [ABSTRACT FROM AUTHOR]

To identify risk factors for stenosis and compare management strategies for stenosis etiology and to examine the efficacy of each approach. Patients with classic bladder exstrophy (CBE), a rare genitourinary malformation, may require construction of a continent urinary stoma (CUS) if incontinence persists. Stomal stenosis is a challenging complication as it is common, progressive, and recurrent. CBE patients who underwent CUS were retrospectively reviewed for risk factors for stenosis including stoma type, prior midline laparotomy number, and umbilicoplasty suture material. Stenosis etiology and management strategies were further reviewed. A total of 260 CBE patients underwent CUS creation. Stenosis developed in 65 patients (25.0%) at a median interval of 1.9 years. Etiology included scar contracture (n = 41), keloid (n = 17), and hypertrophic scar (n = 7). Multifilament suture was the only variable associated with an increased risk of stenosis compared to monofilament suture (P =.009). Almost all patients required surgical intervention. Most scar contractures underwent stomal incision with success in 100%. Hypertrophic scars and keloids responded best to excision with local tissue rearrangement (66.7%). At last follow-up, all patients achieved success. Stomal stenosis is common and challenging for the reconstructive surgeon. Strategies to prevent and effectively manage this are greatly desired. Use of multifilament suture for the umbilicoplasty increased stenosis perhaps from a greater inflammatory response and scarring, while monofilament suture may reduce its incidence. Stomal incision for treating scar contractures, and excision with local tissue rearrangement for hypertrophic scars and keloids may improve successful primary surgical intervention.

To compare the cost-utility of initial management of high-grade T1 non-muscle invasive bladder cancer (HGT1 NMIBC) with intravesical BCG vs immediate radical cystectomy. High-risk NMIBC patients may climb a costly ladder of treatments, culminating in radical cystectomy for oncologic or symptomatic benefit in up to one-third. This high healthcare resource utilization presents a challenging dilemma in balancing sufficiently aggressive management with cost, toxicity, and quality-of-life. Cost-utility of initially managing HGT1 with intravesical BCG and early radical cystectomy with ileal conduit urinary diversion was compared using decision-analytic Markov models. Five-year oncologic outcomes, adverse event rates, and published utility values were extracted from literature. Costs were calculated from a US Medicare perspective in 2021 US dollars. Sensitivity analysis identified drivers of cost and break-even points for recurrence and progression. Mean costs were $26,093 for intravesical BCG and $39,720 for immediate radical cystectomy, though cystectomy generated a gain of 2.2 quality-adjusted life years (QALYs) compared to intravesical BCG. Immediate cystectomy was a more cost-effective management strategy for HGT1 NMIBC with an incremental CE ratios (ICER) of $7120/QALY. The costs associated with cystectomy, TURBT, and BCG toxicity had the greatest impact on ICER. One-way sensitivity analysis demonstrated that intravesical BCG became a cost-effective management strategy if the 5-year recurrence rate of HG T1 was less than 56% or the 5-year progression rate to MIBC was less than 4%. At current prices, treatment of high-grade T1 NMIBC with early radical cystectomy is more cost-effective management strategy than initial treatment with intravesical BCG. [ABSTRACT FROM AUTHOR]

To report a series of women with antibiotic-recalcitrant recurrent urinary tract infections (rUTI) managed with robotic simple cystectomy and ileal conduit urinary diversion. Following Institutional Review Board approval, all female patients who underwent robotic cystectomy for rUTI between 2011 and 2021 were identified from a prospectively-maintained internal database at a tertiary care center. Exclusion criteria included interstitial cystitis, neurogenic bladder, urinary tract neoplasm, or congenital abnormality. Electronic medical records were reviewed by an independent researcher. Patients were also administered the Quality of Life Questionnaire-C30. Twenty-four patients met inclusion criteria. Median age was 75 years (range 53-87). Median rUTI duration was 6 (interquartile range [IQR] 2-10) years. Median urinary tract infections count in the 12-month preceding cystectomy was 5 (IQR 3-9). Infections with multidrug resistant organisms were found in 21 patients (88%). The 30-day postoperative complication rate was 79% (19/24), of which 11% were Clavien-Dindo grade ≥III. The main late complication was parastomal hernia, with 17% requiring repair or revision. At a median of 36 months (range 12-61) post-operatively, the median Quality of Life Questionnaire-C30 global health status score was 50 (range 33-83). Cystectomy is a last-resort management option for women with severely symptomatic end-stage bladders in the setting of antibiotic-recalcitrant rUTI. Patients should be counseled thoroughly regarding possible acute and long-term postoperative complications. Select patients, managed in high-volume referral centers, can benefit from robotic simple cystectomy with ileal conduit urinary diversion. [ABSTRACT FROM AUTHOR]

To synthesise the evidence comparing the incidence rates of UAS post-RARC vs Open Radical cystectomy (ORC) in adults undergoing cystectomy and to compare differential stricture rates between Extracorporeal and Intracorporeal urinary diversion (ECUD vs ICUD). The primary outcome was incidence rate of UAS post RARC vs ORC and the secondary outcome was incidence rate of UAS in RARC post ECUD vs ICUD. Review authors conducted comprehensive search for studies comparing RARC with ORC in terms of incidence of UAS. Furthermore, we conducted a secondary search for studies which compared UAS incidence comparing ECUD and ICUD. We found that RARC may have higher incidence of UAS [OR: 1.39; 95% CI 1.11-1.75; p < 0.0001]. ECUD may result in lower rate of UAS as compared to ICUD [OR: 0.74; 95% CI 0.56 to 0.98; p= 0.04].

Urethral atresia is a rare but clinically significant cause of congenital lower urinary tract obstruction. Initial management options include urinary diversion until definitive urethral reconstruction or progressive urethral dilation. Given the overall rarity of the condition, there are no evidence-based guidelines for the immediate and long-term management of urethral atresia, and clinical practice varies widely. We present an illustrative case managed with progressive urethral dilation alongside urinary diversion to highlight key factors in shared clinical decision making. Ultimately, pooled multi-institutional long-term outcomes data are needed to better guide practice for these patients and their families. [ABSTRACT FROM AUTHOR]

To identify the impact of length of distal ureteral resection on the risk of benign uretero-enteric anastomotic stricture (UEAS) formation following cystectomy and urinary diversion. A database of patients who underwent cystectomy and urinary diversion from 2015 to 2022 was analyzed. Distal ureteral resections were sent for final pathology. The length of resected ureter was collected from pathology reports. Benign UEAS were confirmed with renal scintigraphy, antegrade nephrostogram, or endoscopic evaluation. The relationship between stricture formation and clinical parameters were assessed using T-tests, chi-square tests, and multivariable analysis. A total of 366 patients underwent cystectomy and urinary diversion. Of the cohort, 35 (9.5%) patients developed UEAS. Median time to stricture formation was 12.5 months (IQR 4-30). Of the 711 uretero-enteric anastomoses, 40 (5.6%) ultimately formed a UEAS. Median distal ureteral resection was significantly longer among ureteral anastomoses which did not form a UEAS (2.3 cm vs 1.65 cm, P =.028). Multivariable logistic regression adjusting for surgical approach, prior radiation, ureteral side, and urinary diversion type demonstrated that longer distal ureteral resections were inversely associated with odds of UEAS formation (OR 0.73, 95% CI 0.58-0.92). Multivariable Cox regression analysis similarly showed that length of distal ureteral resection was inversely associated with time to stricture formation (HR 0.78, 95% CI 0.62-0.98). The etiology of benign UIA strictures is multifactorial. Vascular compromise is a critical hypothesis. We found that longer distal ureteral resections (and thus shorter ureters) were associated with a significantly lower risk of stricture formation in cystectomy patients. [ABSTRACT FROM AUTHOR]

To assess if Alexis dual-ring wound protector/retractor reduced the incidence of superficial and deep incisional infection following open radical cystectomy (ORC). Since January 2020, all procedures were performed using the Alexis retractor. We retrospectively reviewed our ORC database and compared patients who were operated on with Alexis with the same number of consecutive patients operated with a stainless steel retractor in the previous period. Data are presented as median and (interquartile range). Seventy-four patients underwent RC with Alexis (group 1) and 74 with stainless steel retractor (group 2). Median age was 73.0(13) in group 1, 73.5(14) in group 2 (P =.338). There were 59(79.7%) men in both groups. The groups were comparable in terms of comorbidities, body mass index, American Society of Anesthesiology score, and neoadjuvant chemotherapy rate. There was no statistically significant difference in type of lymph node dissection and urinary diversion, total surgical time. Postoperative stay was shorter in group 1 [8(4) days vs 9(4) in group 2, P =.012]. Group 2 had a significantly higher rate of both superficial (8.1% vs 18.9%, P =.045) and deep incisional infection (2.7% vs 14.9%, P =.009). At multivariable analysis, body mass index (OR 1.129 95% CI 1.162-1.283, P =.043) was significantly associated with higher odds of superficial incisional infection. The use of Alexis was significantly associated with lower odds of having both superficial (OR 0.274 95%CI 0.033-0.781, P =.023) and deep incisional infection (OR 0.159 95% CI 0.034-0.745, P =.020). The use of Alexis significantly reduces the rate of superficial and deep incisional infection following ORC. [ABSTRACT FROM AUTHOR]

To compare characteristics and outcomes in patients who had radiotherapy (RT) for prostate cancer (PCa) and underwent urinary diversion (UD) due to prostatic fistula (Fistula) vs localized radiation injury (Localized). This study was a retrospective single-institution study. Exclusion criteria included follow-up <3 months, large pelvic tumor, and surgery for cancer control. The Fistula group included fistulization outside of the urinary tract (rectal, soft tissue, thigh, pubic symphysis, and extensive necrosis surrounding the prostate). The group Localized had a multitude of problems; however, all were confined to the urinary tract. Patient characteristics, perioperative variables, and outcomes were compared between groups. Sixty-nine patients were included and had UD from 2009-2022. Median age and time from RT to UD were 73 (interquartile range (IQR) 67.9, 78.1) and 7.3 (IQR 3.2, 12.5) years. There were 29 (42%) and 40 (58%) patients in the Fistula and Localized groups. The Fistula group had a higher rate of abdominal/perineal approach (62.1% vs 12.5%, P <.001), a lower rate of right colon pouch (17.2% vs 40%, P =.043), and a longer operative time (515.7 vs 414.2 minutes, P =.017). Clavien-Dindo complications ≥3 were higher in the Fistula group (44.8% vs 20%, P =.027), including a higher rate of re-operation for recurrent pelvic abscess (37.9% vs 5%, P <.001). Survival for the cohort was 85.5% and did not differ between groups. Patients with prostate fistula after RT for PCa undergoing UD had longer, more complex operations, and higher rates of complications, notably post-operative pelvic abscesses, compared to men with localized RT injury. Long-term survival was comparable in both groups. [ABSTRACT FROM AUTHOR]

To characterize adverse events related to use of the perirectal spacing agent SpaceOAR, we examined the Manufacturer and User Facility Device Experience (MAUDE) database. The MAUDE database was queried for "SpaceOAR" and "Augmenix" from June 2015 (when SpaceOAR was approved by the Food and Drug Administration) to October 2022. Reports were reviewed for adverse events (AEs), operative procedures performed because of the AE, and changes to the radiation plan. AEs were categorized using Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Six hundred fifty-four reports were reviewed. Eighty-four were excluded and 4 reports reviewed 2 separate cases of SpaceOAR administration. Five hundred seventy-four cases were ultimately included. Three deaths were reported (0.5% of all AEs). One point six percent of cases represented CTCAE grade 4 injuries (life-threatening consequences; urgent intervention indicated), 15.9% grade 3 (severe but not immediately life-threatening; hospitalization), 24.2% grade 2 (moderate; local/noninvasive intervention), and 57% of events were CTCAE grade 1 (mild; asymptomatic or mild symptoms). Bowel diversion occurred in 29 cases (9%). Both asymptomatic (n = 311) and debilitating (n = 12) complications of SpaceOAR hydrogel use were identified. Death, gel embolization, anaphylaxis, rectal ulcerations, and infections requiring bowel or urinary diversions were among the complications reviewed. Providers should consider these potential complications before perirectal spacer administration and during patient counseling. [ABSTRACT FROM AUTHOR]

To report peri-operative outcomes of a contemporary series of bladder cancer patients undergoing radical cystectomy (RC) with cutaneous ureterostomy (CU) urinary diversion at a tertiary referral center. We retrospectively identified patients who underwent RC with CU at Mayo Clinic between 2016 and 2021. Clinicopathologic and perioperative characteristics were analyzed using standard descriptive statistics. A total of 31 patients underwent RC with CU at our institution. Median age was 72 years and 21 were male. This was highly comorbid cohort (83% had an American Society of Anesthesiologists [ASA] Physical Status Classification System ≥3; median Charlson Comorbidity index = 8). Median time to flatus, tolerating regular diet, and length of stay were 3 (interquartile range [IQR] 3-3), 3 (IQR 3-4), and 4 days (IQR 4-7), respectively. A total of 14 patients experienced a high-grade complication (Clavien-Dindo ≥3) within 30 days of surgery, and 8 were readmitted. The most common 30-day complication was sepsis, which affected 13% (4/31) of patients. At 90 days postsurgery, the readmission rate was 32% (10/31), most commonly for sepsis. Three patients required reoperation within 90 days, including one patient who required CU revision due to stomal ischemia. One patient died within this time frame from causes unrelated to bladder cancer. In a comorbid, relatively elderly bladder cancer cohort undergoing RC, the use of CU was associated with expeditious surgery and postoperative recovery. CU represents an option for urinary diversion in high-risk patients undergoing RC. Higher rate of postoperative ureteral obstruction can be pre-emptively addressed with chronic stent placement.

To compare pre-and post-operative opiate use in a large cohort of interstitial cystitis/bladder pain syndrome (IC/BPS) patients who underwent cystectomy with urinary diversion (CWUD). A retrospective analysis was completed using a database of IC/BPS patients who underwent CWUD at a single institution from 2014 to 2022. In addition to demographic information, bladder capacity and Hunner lesion status were documented for each patient. Opiate use (milligram morphine equivalents [MME]) was calculated for each patient and change in MME (ΔMME) was calculated by subtracting pre-CWUD MME from post-CWUD MME. Paired t test was used to compare ΔMME for all parameters except age, where a Pearson's correlation was used. The analysis included 82 patients (17 M; 65 F) that underwent CWUD as follows: 53 ileal conduit diversions, 11 neobladders, and 18 Indiana Pouches. Mean pre-CWUD MME use was 4509.57 and mean post-CWUD MME was 1788.48 with a ΔMME of − 2721.09 (P <.001). ΔMME was not significantly different based on gender (P =.597), bladder capacity (P =.754), age (P =.561), or Hunner lesion status (P =.085). IC/BPS patients using opiates primarily for relief of pain directly related to their condition show a significant decrease in opiate use following CWUD, which likely represents significant pain reduction and implicates the bladder as the primary source of that pain.

Population-based practice patterns in the United States reveal continent diversions are only performed in 8%-10.4% of patients. 1-4 Ideally, for patients undergoing radical cystectomy the choice of urinary diversion should be influenced by clinical factors and patient preference, with discussions surrounding quality of life. Unfortunately, receipt of continent diversion has been shown to be influenced by a plethora of other factors such as surgeon preference/training, geography, socioeconomic status, gender, and hospital volume. 1-3 Thus, by providing detailed instruction and long-term follow-up, we hope to mitigate some of these disparities by changing the perceptions regarding feasibility and complications of continent diversions. To provide step-by-step instruction and to report long-term clinical outcomes in bladder cancer patients receiving an Indiana pouch continent cutaneous urinary diversion (CCUD) after robot-assisted radical cystectomy. After Institutional Review Board approval, a prospectively maintained bladder cancer database was queried for patients with T1-T4, N0-N1, M0 bladder cancer undergoing radical cystectomy with CCUD at a tertiary referral center from 2004 to 2020. Complications at 30- and 90-day were recorded according to the Clavien-Dindo classification. Continence rates were recorded by chart review. A total of 97 patients were included with a median follow-up of 93 months. Clinically, 91.8% had ≤T2 disease and 29.9% received neoadjuvant chemotherapy. The median length of surgery was 8.0 hours, length of hospital stay was 8.3 days, and urinary continence rate was 99.0%. The overall complication rate was 73.2% and 76.5% at 30- and 90-day, respectively. The major complication rate (Clavien III-V) was 17.5% at 30-day and 22.7% at 90-day. The most common major complications were abdominal infection and uretero-colonic stricture. The readmission rate was 21.4% and median overall survival was 108 months. CCUD provides exceptional functional outcomes with acceptable complication rates compared to other diversion types. CCUD is a reliable reconstructive option and with this step-by-step video as a reference, we hope it will be offered to more patients. [ABSTRACT FROM AUTHOR]

To collate available data via systematic review considering etiology, presentation, and treatment of Uro-Symphyseal Fistula (USF) in order to inform a contemporary management framework. A systematic review was performed according to the Cochrane Handbook and registered in PROSPERO (CRD42021232954). MEDLINE and CENTRAL databases were searched for manuscripts considering USF published between 2000 and 2022. Full text manuscripts were reviewed for clinical data. Univariate statistical analysis was performed where possible. A total of 31 manuscripts, comprising 248 USF cases, met inclusion criteria. Suprapubic pain and difficulty ambulating were common symptoms. MRI confirmed the diagnosis in 95% of cases. Radiotherapy for prostate cancer was the most common predisposing factor (93%). Among these patients, prior endoscopic bladder outlet surgery was common (83%; bladder neck incision/urethral dilatation n = 59, TURP/GLL PVP n = 34). In those with prior prostatic radiation, conservative management failed in 96% of cases. Cystectomy with urinary diversion (86% n = 184) was favored over bladder-sparing techniques (14% (n = 30) after prior radiation. In radiation naïve patients, conservative management failed in 72% of patients, resulting in either open fistula repair with flap (62%) or radical prostatectomy (28%). Prior radiotherapy is a significant risk factor for USF and almost always requires definitive major surgery (debridement, cystectomy, and urinary diversion). On the basis of the findings within this systematic review, we present management principles that may assist clinicians with these complex cases. Further research into pathogenesis, prevention, and optimal treatment approach is required. [ABSTRACT FROM AUTHOR]

To investigate the safety, efficacy, and surgical approach of percutaneous bladder calculi removal in adult patients with prior lower urinary tract reconstruction utilizing bowel using a single-institution database. Twenty patients with prior history of lower urinary tract reconstruction (continent cutaneous urinary reservoir, augmentation enterocystoplasty with catheterizable channel, or ileal neobladder) who underwent percutaneous cystolitholapaxy from 2014 to 2020 were identified from an IRB-approved database. Analysis of patient demographics, operative details, stone composition, stone-free rates, recurrence, and associated complications was performed. Percutaneous access and either ultrasonic lithotripter or laser lithotripsy were utilized to remove bladder stones. Over half of the patients also underwent concomitant renal stone removal via percutaneous removal or retrograde ureteroscopy. Postoperative computed tomography imaging revealed complete bladder stone clearance in 90% of patients. There were no notable complications from percutaneous bladder stone removal and most patients were discharged either the same day or within 24 hours. Urine and stone analysis revealed infection was present in the majority of patients. Bladder stones recurred in 45% of patients after more than 2 years of follow-up, on average. Percutaneous cystolitholapaxy is a safe and effective approach for the removal of moderate-sized bladder calculi in adults with prior lower urinary tract reconstruction utilizing bowel. Its efficacy and minimally invasive nature make it the approach of choice at our institution. [ABSTRACT FROM AUTHOR]

To determine the cost-effectiveness of mesh placement in patients undergoing ileal conduit urinary diversion for bladder cancer. Long-term studies have shown that parastomal hernias (PSH) occur in more than half of all stomas. Mesh prophylaxis has been shown to reduce PSH after end-colostomy and ileal conduits. However, no cost-effectiveness studies on mesh prophylaxis have been performed for this population. We created a Markov model incorporating the costs and effectiveness of mesh prophylaxis for patients undergoing radical cystectomy and ileal conduit construction. Costs were obtained from the literature and adjusted to 2022 US dollars. Effectiveness was measured in quality-adjusted life years (QALY). 1- and 2-way sensitivity analyses were performed to test the robustness of our model. In stage I-IV bladder cancer, prophylactic mesh placement was costlier, but more effective in providing quality of life compared with no mesh placement at index surgery. Average incremental cost between the 2 strategies across all stages was an additional $897 when mesh was utilized. Incremental effectiveness averaged 0.49 additional QALY across all stages. This resulted in an incremental cost-effectiveness ratio of $2114.71/QALY. Sensitivity analyses indicated that benefit of mesh placement was sensitive to the probability of mesh infection. In patients undergoing ileal conduit urinary diversion for bladder cancer, mesh prophylaxis at the time of radical cystectomy is an overall cost-effective strategy in preventing PSH for patients presenting with all stages of bladder cancer.

To evaluate a subset of patients who develop strictures requiring Ileal Ureter (IU) in the setting of prior urinary diversion or augmentation (ileal conduits, neobladders, continent urinary diversions). To our knowledge, there are no prior studies on patients with IU substitution into established lower urinary tract reconstructions. A retrospective review of patients (18 years) undergoing IU creation from 1989 to 2021 was performed. A total of 160 patients were identified. In total, 19 (12%) patients had IUs into diversions. We examined demographics, stricture cause, diversion type, renal function, and postoperative complications. Nineteen patients were identified. Sixteen were male. Mean age was 57.7(SD 17.0) years. Diversions included continent urinary reservoirs (4), neobladders (5), ileal conduits (7), and bladder augmentations with Monti channels (3). Fifteen had unilateral surgery, and 4 had bilateral "reverse 7" IU creation. Average length of stay was 7.6 days (SD 2.9). Average follow-up was 32.9 months (SD 27). Mean preoperative creatinine was 1.5 (SD 0.4); mean postoperative creatinine at most recent follow-up was 1.6 (SD 0.7). There was no significant difference between pre- and postoperative creatinine (P =.18). One patient had a ventriculoperitoneal Shunt infection resulting ventriculoperitoneal shunt externalization, 1 had Clostridium difficile infection potentially causing an entero-neobladder fistula, 2 with ileus, 1 urine leak, and 1 wound infection. None required renal replacement therapy. Patients with urinary diversions and prior bowel reconstructive surgeries with subsequent ureteral strictures are a challenging cohort of patients. In properly selected patients, ureteral reconstruction with ileum is feasible and preserves renal function with minimal long-term complications. [ABSTRACT FROM AUTHOR]

Benign ureterointestinal anastomotic stricture (UIAS) is a recognized long-term complication following radical cystectomy with urinary diversion (UD). The incidence of UIAS following robotic-assisted radical cystectomy varies, with reported rates ranging from 6.5%-25.3%. 1 Although endourologic treatments have been employed, their overall success rate is relatively low, ranging from 26%-50%. In contrast, open surgical revision has demonstrated higher success rates, between 80% and 91%. 2,3 Given the morbidity associated with open surgery, there has been a shift toward minimally invasive approaches. The robotic approach offers a minimally invasive alternative to open surgery that is not inferior, with similar outcomes for UIAS reconstruction. 4 In this video, we demonstrate a robotic technique for the revision of UIAS, which aims to combine the effectiveness of open surgery with the reduced morbidity of a minimally invasive approach. From May 2020-March 2023, 6 patients underwent surgery. The mean age was 62 years (range 49-68 years). Among these, 2 patients received conduits in open technique and 4 were provided with robotic neobladders. The strictures were located as follows: 2 on the left side, 2 on the right, and 2 on both sides. The average time to stricture formation in the series was 4.5 months. The case presented involves a 49-year-old man who developed a left ureteroileal anastomotic stricture (UIAS) 6 months following robot-assisted radical cystectomy and neobladder creation. The obstruction was managed initially with nephrostomy tube drainage. The surgical technique employed is demonstrated in a step-by-step manner. Standard Da Vinci surgical instruments were used. The patient was positioned in a 30° Trendelenburg position, with port placement similar to that in robotic prostatectomy. The pneumoperitoneum was established through a supraumbilical mini-laparotomy using the Hasson technique. Adhesions around the neobladder were carefully freed. Subsequently, the affected ureter and the stricture were identified and localized. This was achieved by intraluminal application of 10 mL of indocyanine green solution (2.5 mg/mL concentration) through the nephrostomy catheter. The ureter was mobilized as needed. The ureteral stricture was identified and then fully excised. To exclude any malignancy at the ureteral margin, a frozen section analysis was conducted. The ureter was then spatulated. Reanastomosis between the ureter and neobladder was performed using a continuous 4-0 Stratafix suture. A double-J ureteral catheter was inserted to secure the anastomosis, and the anastomosis was completed over this catheter. The mean operative time at the robotic console was 122 minutes, ranging from 80-160 minutes, and the mean blood loss was 42 mL, within a range of 50-100 mL. Intraoperative frozen sections revealed no evidence of malignancy in all cases. No postoperative complications exceeding Clavien-Dindo grade 3 were observed. Two patients were treated for symptomatic urinary tract infections. The median length of stay in the hospital was 4 days, with a range of 2-7 days. Median times for cystography with transurethral catheter removal and double-J catheter removal were 15 postoperative days (range: 12-27) and 23 postoperative days (range: 17-37), respectively. No recurrence of the condition was observed during a mean follow-up period of 23 months (range 6-40 months). The robotic approach represents a viable, minimally invasive alternative to conventional open surgery for the reconstruction of UIAS following urinary diversion. The surgical outcomes are comparable to those of open surgery, with the added benefits of a minimally invasive approach, including reduced blood loss and shorter hospital stays.

Objective: To determine long-term kidney outcomes in boys with posterior urethral valve (PUV) undergoing either primary valve ablation or urinary diversion with matched baseline kidney function.Methods: After retrospective review of patients managed for PUV at our institution, propensity score matched analysis was conducted using nadir serum creatinine with logistic regression analysis. Nearest neighbor matching was used to allocate boys to primary urinary diversion and primary ablation groups. Primary outcomes included kidney function by creatinine or estimated glomerular filtration rate (eGFR), chronic kidney disease (CKD), and end-stage renal disease (ESRD). Comparative statistics by odds ratio (OR) and hazard ratios (HR) on survival analysis were calculated.Results: A total of 21 boys undergoing primary diversion were matched with 42 boys undergoing ablation using nadir serum creatinine and follow-up time with a median follow-up of 4.8 years. After matching, there was no significant difference in last follow-up kidney function by creatinine (p=0.99) or eGFR (p=0.98). Primary diversion was not associated with increased likelihood of developing CKD stage 3 (OR 1.33; p=0.31) or ESRD (OR 1.88; p=0.35 and HR 1.85; p=0.30) compared to primary ablation.Conclusions: Our propensity matched study suggests that long-term kidney function and kidney outcomes are similar between primary ablation and primary diversion after adjusting for baseline kidney function in boys with PUV.

Objective: To compare the perioperative and oncologic outcomes associated with RCNU to a matched cohort undergoing RC alone. Simultaneous radical cystectomy and nephroureterectomy (RCNU) for synchronous upper tract and bladder urothelial carcinoma is an uncommon procedure. Sparse literature exists comparing outcomes in patients treated with radical cystectomy (RC) alone versus RCNU.Methods: Adults treated with RCNU for urothelial carcinoma of the bladder (UCB) and upper tract urothelial carcinoma (UTUC) between 1980 and 2020 were identified. Patients were matched 2:1 to patients undergoing RC alone for UCB based on age (+/- 5 years), gender, BMI (+/- 5), Charlson Comorbidity Index, pathologic staging (stage ≤pT2 vs >pT2), and receipt of neoadjuvant chemotherapy. Outcomes included overall survival (OS), recurrence free survival (RFS), cancer specific survival (CSS), 30-day complications, length of stay (LOS), operative time, and estimated blood loss (EBL).Results: A total of 39 patients undergoing RCNU were identified and matched to 74 patients undergoing RC. There were no significant differences in LOS, EBL, or 30-day complication rates. Operative time was significantly longer in the RC cohort. OS (HR 0.58, CI 0.35 - 0.97, p=0.036) was significantly better for patients undergoing RC alone, while no significant difference was noted in RFS (HR 0.65, 0.34-1.24) and CSS (HR 0.58, CI 0.31-1.08, p=0.08).Conclusions: Patients undergoing RCNU had significantly lower OS compared to a matched group of patients undergoing RC alone. Perioperative outcomes between the groups did not differ significantly. This data can inform patient counseling for treatment of this rare disease state. [ABSTRACT FROM AUTHOR]

We present a case of chemotherapy refractory spindle cell rhabdomyosarcoma of the lower urinary tract in a 15-month-old female that ultimately required consolidative surgery with cystectomy, urethrectomy, ovarian-sparing hysterectomy, bilateral salpingectomy, anterior vaginal wall resection, and bilateral pelvic lymph node dissection. Genitourinary reconstruction was performed by ileal conduit creation and vaginoplasty. After completion of her maintenance postoperative chemotherapy regimen, the patient has remained disease-free for approximately 27 months. [ABSTRACT FROM AUTHOR]

Objective: To identify trends in complications following robot-assisted radical cystectomy (RARC) using a multi-institutional database, the International Robotic Cystectomy Consortium (IRCC).Methods: A retrospective review of the IRCC database was performed (2976 patients, 26 institutions from 11 countries). Postoperative complications were categorized as overall or high grade (≥ Clavien Dindo III) and were further categorized based on type/organ site. Descriptive statistics was used to summarize the data. Multivariate analysis (MVA) was used to identify variables associated with overall and high-grade complications.  Cochran-Armitage trend test was used to describe the trend of complications over time.Results: 1777 (60%) patients developed postoperative complications following RARC, 51% of complications occurred within 30 days of RARC, 19% between 30-90 days, and 30% after 90 days. 835 patients (28%) experienced high-grade complications. Infectious complications (25%) were the most prevalent, while bleeding (1%) was the least. The incidence of complications was stable between 2002-2021. Gastrointestinal and neurologic postoperative complications increased significantly (P < .01, for both) between 2005 and 2020 while thromboembolic (P = .03) and wound complications (P < .01) decreased. On MVA, BMI (OR 1.03, 95%CI 1.01-1.05, P < .01), prior abdominal surgery (OR 1.26, 95%CI 1.03-1.56, P = .03), receipt of neobladder (OR 1.52, 95%CI 1.17-1.99, P < .01), positive nodal disease (OR 1.33, 95%CI 1.05-1.70, P = .02), length of inpatient stay (OR 1.04, 95%CI 1.02-1.05, P < .01) and ICU admission (OR 1.67, 95%CI 1.36-2.06, P < .01) were associated with high-grade complications.Conclusion: Overall and high-grade complications after RARC remained stable between 2002-2021. GI and neurologic complications increased, while thromboembolic and wound complications decreased. [ABSTRACT FROM AUTHOR]

Congenital bladder underdevelopment has detrimental genitourinary effects. We present a male infant with declining renal function, recurrent urinary tract infections, and epididymo-orchitis, in the setting of bilateral high grade hydronephrosis and vesicoureteral reflux. Cystoscopic evaluation revealed the presumed "bladder" to be a massively dilated prostatic urethra. The small dysplastic "true bladder" was found at the anterior surface of the prostatic urethra with massively dilated ureteral orifices. Temporizing diversion was performed in the form of bilateral cutaneous ureterostomies, with an ultimate plan for reconstructive bladder surgery. This case presents diagnostic challenges utilizing current modalities due to a massively dilated prostatic urethra in the rare case of bladder dysplasia. [ABSTRACT FROM AUTHOR]

Objective: To quantify the short-term burden associated with continent diversion relative to ileal conduit creation.Methods: Bladder cancer patients who underwent radical cystectomy in 2019 and 2020 were identified in the American College of Surgeons National Surgical Improvement Program database using current procedural terminology codes and pathology reports. Patients were grouped by urinary diversion performed: ileal conduit versus continent diversion (neobladder or cutaneous reservoir). Multiple logistic regression was used to examine the association between type of urinary diversion and 30-day outcomes, including postoperative complications, all-cause readmissions, and mortality, adjusting for baseline differences.Results: Of 4,755 patients who underwent radical cystectomy, 677 underwent continent diversion (14.2%). These patients were significantly younger (median 62 vs 71 years, P <.01) and less likely to have diabetes (13.6% vs 20.1%, P <.01), COPD (3.7% vs 7.1%, P<0.01), and prior pelvic radiation (5.5% vs 13.1%, P <.01). A greater proportion of continent diversion patients experienced a postoperative complication (56.0% vs 48.9%, P <.01) and all-cause readmission (30.3% vs 20.4%, P <.0). After adjustment, continent diversion patients had 1.4 (95% CI: 1.1-1.7) and 1.7 (95% CI: 1.4-2.1) times the odds of experiencing a postoperative complication or all-cause readmission, respectively. There was no statistically significant difference in mortality (OR 1.2, 95% CI: 0.5-2.9).Conclusion: Compared to ileal conduit creation, continent urinary diversion is associated with increased odds of postoperative complications and readmission to the hospital within 30 days of surgery. Bladder cancer patients undergoing cystectomy and seeking continent diversion should be counseled on the increased short-term morbidity associated with this specific type of diversion.

Objective: This study aimed to investigate the role of computed tomography angiography (CTA) and three-dimensional (3D) reconstruction of renal arteries in the evaluation of bleeding after mini- percutaneous nephrolithotomy (PCNL).Methods: Thirty-one consecutive patients with continuous renal hemorrhage after mini-PCNL were enrolled from January 2015 to January 2022. Demographic and clinical data were retrospectively recorded and analyzed. All patients had received CTA evaluation and subsequently digital subtraction angiography (DSA) embolization to manage renal bleeding. CTA and 3D reconstruction of renal arteries were performed using the 320 multi-detector computed tomography technique and the images were evaluated by experienced radiologists. DSA embolization were performed by an interventional radiologist with more than 10 years of experiences.Results: CTA and 3D construction of renal arteries showed 28 cases of vascular lesions (28/31, 90.3%), including 15 cases of pseudoaneurysm (15/28, 53.6%), 9 cases of arteriovenous fistula (9/28, 32.1%), and 4 cases of suspicious bleeding spot (4/28, 14.3%). While DSA revealed 31 cases of vascular lesions (100%), including 15 cases of pseudoaneurysm (15/31, 48.4%), 10 cases of arteriovenous fistula (10/31, 32.3%), 6 cases of bleeding spot and (6/31, 19.4%). The serum creatinine level was elevated slightly before mini-PCNL and after DSA embolization (73.1±18.1 vs 92.1±33.6, P <.01). 15 patients (15/31, 48.4%) required blood transfusion, with mean blood transfusion volume of 700 ml ±660 ml (range, 400 ml-1800 ml). The bleeding was controlled without any further severe complications.Conclusion: CTA and 3D reconstruction of renal arteries were safe and effective in diagnosing renal arterial bleedings after mini-PCNL, with a sensitivity of 90.3% and a specificity of 100%.

Objective: To identify associations between preoperative psychiatric diagnoses and perioperative outcomes after RC.Methods: The Florida Inpatient Data File was used to identify patients who underwent RC from 2013 to 2019. ICD-10 codes for a mood or anxiety disorder were identified and analyzed as a 3-level variable: neither, one of these, or both. Outcomes included inpatient mortality, non-home discharge, in-hospital complications, and length of stay. Mixed-effects logistic regression (accounting for clustering within hospitals) and negative binomial regression models were utilized.Results: We identified 4396 RC patients, including 306 (7.0%) with a mood disorder and 389 (8.8%) with an anxiety disorder. After multivariable adjustment, there was no significant association between mood and/or anxiety disorders with mortality or the presence or number of in-hospital complications. However, a mood or anxiety disorder was significantly associated with increased odds of non-home discharge (OR 1.60, 95% CI 1.20-2.14) and longer length of stay (IRR 1.13, 95% CI 1.07-1.19); these associations were also increased among patients with both mood and anxiety disorder diagnoses (non-home discharge OR 2.66, 95% CI 1.61-4.38; length of stay IRR 1.12, 95% CI 1.01-1.24).Conclusion: Patients with mood and/or anxiety disorders undergoing RC had longer length of stay and increased odds of discharge to a non-home facility despite similar risks of perioperative complications. These data suggest an opportunity for perioperative intervention to address these disparities in postoperative outcomes. However, further work is needed to determine the underlying causes of these differences and to develop effective interventions. [ABSTRACT FROM AUTHOR]

Objective: To describe the outcomes of ileal conduit as a salvage therapy for refractory lower urinary tract dysfunctions (LUTDs) due to multiple sclerosis (MS) in a national neurourology referral center network.Methods: A retrospective multicenter French study was carried out to identify MS patients who underwent non-continent urinary diversion for refractory LUTDs from January 2010 to December 2015. Multiple sclerosis status, urological history, surgical indication and technique, postoperative complications, renal anatomy and function at last follow-up as well as number of rehospitalizations for urinary tract infections (UTI) were collected. Preoperative and postoperative urinary-related quality of life (urQoL) through the Qualiveen short-form questionnaire (QSF) and patient global impression of improvement (PGI-I) were collected and analyzed.Results: Overall, 10 centers identified 211 patients with a mean age of 54±11 and mean preoperative EDSS (expanded disability status scale) score of 7.3±0.9. The main indication for diversion was MS progression leading to impossible intermittent self-catheterization (55%). Cystectomy was performed either by open (34.6%), laparoscopic (39.3%) or robotic (21.8%) approach (unknown: 4.2%) with cystectomy in all cases. Early complications were reported in 42% of the patients, mainly Clavien I or II grades. There was no difference in GFR (glomerular filtration rate) after surgery. After diversion, patients had fewer hospitalizations for UTI and better urQoL on QSF confirmed by evaluation of PGI-I.Conclusion: This study, reporting the largest series of ileal conduit in selected MS patients with end-stage LUTDs, showed significant improvement in symptomatic UTI and quality of life with a low high-grade complication rate.

Objective: To investigate the impact of extirpative surgery for pubic bone osteomyelitis with pubovesical fistula on prostate cancer survivors' physical and mental health.Materials and Methods: The Short Form 12 (SF-12) is a validated instrument for assessing health-related quality of life (HRQOL). We reviewed a prospectively maintained database of patients treated with extirpative surgery for pubovesical fistula from 2017-2021 who completed the SF-12. Wilcoxon signed-rank and McNemar's tests were used to analyze changes in SF-12 following surgery. Narcotic prescriptions in the year before and after surgery were assessed as an additional measure of pain burden.Results: Eighteen patients were included. Four had pre-operative SF-12s, 3 had post-operative SF-12s, and 11 had both. Median age was 76.5 years (IQR 71.75-80.00). All patients had previous radiation for prostate cancer. Compared to global pre-operative scores, post-operative physical composite scores (PCS) significantly increased (29.95 ± 8.59 vs 42.48 ± 7.18; P <.001), but mental composite scores (MCS) were similar (45.35 ± 9.98 vs 52.21 ± 8.23). When comparing individual, paired pre-operative and post-operative scores there was a significant improvement in PCS (30.56 ± 9.87 vs 45.45 ± 8.56; P = .005), but not MCS (47.49 ± 6.92 vs 51.60 ± 8.88). Median morphine milligram equivalent significantly decreased in the year post-surgery compared to the year prior (103.1, 33.0-250.9 vs 34.25, 0.0-105.9; P = .0008).Conclusion: For prostate cancer survivors with pubovesical fistula and pubic bone osteomyelitis, urinary diversion with pubic bone resection improves physical functioning and decreases narcotic prescriptions without untoward effects on mental health.

Objective: To analyze the location and management of urethral stricture/stenosis in patients treated with High-intensity focused ultrasound (HIFU) of the prostate as well as to describe patient reported satisfaction in these men.Methods: Patients with a history of HIFU requesting consultation for stricture were identified from 2010 to 2020. Demographic and prior treatment data were recorded. Patients who presented for evaluation underwent retrograde cystoscopy, retrograde urethrogram, voiding cystourethrogram, and antegrade cystoscopy through a suprapubic tract. Patients who only had virtual consultation and did not present for in-person evaluation, were followed longitudinally to assess long-term outcomes and quality of life.Results: Over the 10-year study period, 17 patients were identified with a mean age of 65.8 years. Prior to initial consultation, a total of 88% of patients had at least 1 failed surgical intervention at a mean of 45 months post-HIFU. The majority of patients (94%) had strictures that included but were not necessarily limited to the prostatic urethra. Patients underwent various treatments postevaluation, favoring endoscopic therapy (38%), and proximal diversion (20%) at a mean follow-up of 68.2 ± 7.5 months. Only 38% reported satisfaction with urinary symptoms.Conclusion: Urethral narrowing post-HIFU appears to overwhelmingly involve the prostatic urethra. Patients usually have a significant treatment burden over a prolonged period and are often managed with repeated endoscopic treatment, extirpative prostatic surgery, or urinary diversion as they have obstruction that is not amendable to urethral reconstruction. Most patients with HIFU strictures experience a diminished QOL due to persistent urinary symptoms. [ABSTRACT FROM AUTHOR]

Objectives: To describe the most recent 7 year experience with 137 Indiana pouch patients at a single institution and provide data on complications with this type of urinary diversion during the first postoperative year.Methods: We queried our bladder cancer database to identify all patients who underwent cystectomy with continent catheterizable urinary reservoir between 2012 and 2018. Pre-, intra-, and postoperative data were collected. Complications were stratified into early (within 90 days) and midterm (90-365 days). The primary outcomes were postoperative complications, and overall and cancer-specific mortality.Results: A total of 137 patients underwent open cystectomy with Indiana pouch creation. Of these, 93% were radical cystectomies. On average, the operation took 422 minutes. There were 53 (39%) patients who experienced any type of complication during the first postoperative year (Clavien II-V). Twenty-five patients (18.2%) readmitted in the early postoperative period vs 18 (13.1%) patients midterm. There were 10 (7.3%) patients that required early reoperation and 11 (8%) in the midterm period. The overall mortality rate was 1.5% early and 3.7% midterm, with the majority of the mortality rate attributed to cancer progression (85.7%).Conclusion: Patients undergoing continent catheterizable reservoir urinary diversion appear to have comparable complication rates to other urinary diversions published in the literature. At high-volume urologic institutions, Indiana Pouch creation is a suitable option for select patients desiring a continent diversion. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the oncologic outcomes of pT0 after robot-assisted radical cystectomy (RARC).Methods: A retrospective review of the International Robotic Cystectomy Consortium database was performed. Patients with pT0 after RARC were identified and analyzed. Data were reviewed for demographics and pathologic outcomes. Kaplan-Meier curves were used to depict recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS). Multivariate stepwise Cox regression models were used to identify variables associated with RFS and OS.Results: Four hundred seventy-one patients (18%) with pT0 were identified. Median age was 68 years (interquartile range (IQR) 60-73), with a median follow up of 20 months (IQR 6-47). Thirty-seven percent received neoadjuvant chemotherapy and 5% had pN+ disease. Seven percent of patients experienced disease relapse; 3% had local and 5% had distant recurrence. Most common sites of local and distant recurrences were pelvis (1%) and lungs (2%). Five-year RFS, DSS, and OS were 88%, 93%, and 79%, respectively. Age (hazards ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = 0.02), pN+ve (HR 11.48, 95% CI 4.47-29.49, P < .01), and reoperations within 30 days (HR 5.53, 95% CI 2.08-14.64, P < .01) were associated with RFS. Chronic kidney disease (HR 3.24, 95% CI 1.45-7.23, P < .01), neoadjuvant chemotherapy (HR 0.41, 95% CI 0.18-0.92, P = .03), pN+ve (HR 4.37, 95% CI 1.46-13.06, P < .01), and reoperations within 30 days (HR 2.64, 95% CI, 1.08-6.43, P = .03) were associated with OS.Conclusions: Despite pT0 status at RARC, 5% had pN+ disease and 7% of patients relapsed. Node status was the variable strongest associated with RFS and OS in pT0. [ABSTRACT FROM AUTHOR]

Objective: To retrospectively evaluate enhanced recovery after surgery (ERAS) protocol administration, hospital length of stay, 30-day readmission, and complication rates among cystectomy and/or urinary diversion patients with benign or malignant indication.Materials and Methods: Data was extracted retrospectively for cystectomy and/or urinary diversion performed at our institution from June 2016 to May 2019. Descriptive statistics, Chi squared, Wilcoxon rank-sum, binary logistic regression, and linear regression functions in R 4.0.4 (R Foundation), R Package "Tidverse" V1.3.0.9, and RStudio V1.44.1106 (RStudio, PBC) were used to analyze data.Results: 102 patients met selection criteria with 36 and 66 patients in the benign and malignant indication cohorts, respectively. Significant differences between cohorts included BMI, age, opioid exposure, and spinal anomalies. The malignant cohort had higher ERAS completion rates for preoperative and intraoperative protocols (41% and 53% vs 14% and 19%). The mean ERAS item administration for benign and malignant indication patients differed significantly (2.9 vs 4.2, P < 0.01). Logistic regression demonstrated benign indication was significantly associated with ERAS failure (OR 4.25, 95% CI 1.18 - 21.03, P = 0.043). Higher ERAS item administration sum was associated with shorter hospitalizations and lower complication rates (P = < 0.01, P = 0.019). No association was observed for 30-day readmission.Conclusion: The benign urinary diversion/cystectomy population more frequently possesses characteristics adverse to ERAS protocol completion and in our study received fewer ERAS protocol items. This was associated with longer hospitalizations and higher postoperative complication rates. Population-specific ERAS protocols targeted at increasing ERAS completion could reduce morbidity.

Objective: To assess the impact of trainee involvement in surgery on perioperative and oncological outcomes of patients undergoing radical cystectomy (RC).Materials and Methods: We reviewed the records of patients undergoing RC for urothelial carcinoma between 2000 and 2015 at our institution. Trainee level was categorized as fellow, chief, senior and junior residents. Demographic, perioperative and oncological outcomes were recorded and compared between the groups. Specifically, operative time, 30-day complications, severe complications (Clavien III-V) and oncological outcomes (overall, cancer-specific and recurrence-free survival) were assessed.Results: A total of 895 patients were included for study. On multivariable analysis, operative times were 30-40 minutes longer in procedures assisted by junior residents as compared to more senior trainees. Notably, trainee level was not associated with overall or severe complications on multivariable analyses. Similarly, trainee level was not associated with oncologic outcomes.Conclusion: While cases assisted by junior residents had longer operative times, complication rates and oncological outcomes were comparable across trainee groups. Trainee level does not appear to have an impact on perioperative and oncological outcomes of RC for urothelial carcinoma. [ABSTRACT FROM AUTHOR]

Objective: To determine exposure rates to antibiotics prior to radical cystectomy and determine if there is correlation with post-operative infections.Methods and Materials: 2248 patients were identified in the 2016 SEER-Medicare linkage who underwent radical cystectomy between 2008 and 2014 with complete prescription information. An outpatient prescription for an antibiotic within 30 days prior to cystectomy was considered exposure. Antibiotic class and combinations were recorded. Postoperative infectious diagnoses and readmissions were tabulated within 30 days of cystectomy.Results: Fifty one percent of patients (n = 1149) were prescribed an outpatient antibiotic prior to cystectomy. Patients receiving antibiotics were more likely to be female (31% vs 25%, P < .01) and had been diagnosed with an infection (17% vs 11%, P < .01). Antibiotic bowel prophylaxis was prescribed to 42% of patients receiving antibiotics. Postoperatively, the exposure group had higher rates of any infection, (56% vs 51% P < .01) and UTI (36% vs 31% P < .01). All-cause readmission within 30 days was higher in the exposure cohort (26% vs 22%, P = .02) Multivariable logistic regression showed outpatient preoperative antibiotics were an independent risk factor for any infection (HR 1.19, P < .05) and readmission (hazards ratio 1.24, P = .03) in the 30 days after radical cystectomy.Conclusion: Outpatient antibiotic use prior to radical cystectomy is common and may be associated with increased risk of postoperative infection and readmission. Antibiotic use prior to radical cystectomy should be examined as a modifiable factor to decrease post-operative morbidity. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the prevalence of urinary (UI) and fecal incontinence (FI) and the incontinence-related quality of life (QoL) in adolescent and adult patients with cloacal exstrophy (CE) in Germany.Patients and Methods: CE-patients of a tertiary care center and the German support group for anorectal malformations (SoMA e.V.) were included (October 2015 until September 2020). Data were assessed using a composed questionnaire consisting of 18 self-generated questions and two validated German questionnaires (King's health questionnaire, Questionnaire on Quality of Life in Fecal Incontinence (FLQAI)).Results: Out of 23 included patients, 19 had continent and 3 incontinent urinary diversions (UD), 1 was unspecified; 2/23 were on dialysis. 73.7% (14/19) had undergone bladder augmentation, 4/19 had a pouch, 1/19 a neobladder. 94.7% (18/19) had a continent cutaneous channel and performed intermittent self-catheterization. UI was common (71.4%, 15/21). Neither the UD nor the involuntary loss of urine itself had a significant impact on QoL. Comparing the King's health questionnaire results, UI-related QoL of CE-patients was significantly lower than in a published reference group. 78.3% (18/23) had a bowel stoma. 34.8% (8/23) reported involuntary stool-soiling. Neither the way of bowel-emptying nor involuntary stool-soiling itself showed significant influence on FI-related QoL in the FLQAI. FLQAI items showed significant differences only for one of two published reference groups.Conclusion: Long-term incontinence rates in adolescent and adult CE-patients are high. Incontinence-related QoL was reduced compared to published reference groups but was minimally influenced by incontinence itself, the type of UD or the way of bowel-emptying, respectively.

Equations estimating the glomerular filtration rate are important clinical tools in detecting and managing kidney disease. Urologists extensively use these equations in clinical decision making. For example, the estimated glomerular function rate is used when considering the type of urinary diversion following cystectomy, selecting systemic chemotherapy in managing urologic cancers, and deciding the type of cross-sectional imaging in diagnosing or staging urologic conditions. However, these equations, while widely accepted, are imprecise and adjust for race which is a social, not a biologic construct. The recent killings of unarmed Black Americans in the US have amplified the discussion of racism in healthcare and has prompted institutions to reconsider the role of race in estimation of glomerular filtration rate equations and raced-based medicine. Urologist should be aware of the consequences of removing race from these equations, potential alternatives, and how these changes may affect Black patients receiving urologic care.

Objective: To study the effect of surgeon-administered Transversus Abdominis Plane block (sTAP) on opioid usage and length of stay (LOS).Methods: Starting in April 2018, two surgeons at our institution gradually introduced sTAP for radical cystectomy (RC) patients. We performed a retrospective observational cohort analysis of RC patients catalogued in a prospectively maintained database using the Enhanced Recovery After Surgery Interactive Auditing System. Two surgeons adopted the sTAP block technique in April 2018. We included patients undergoing RC for bladder malignancy under Enhanced Recovery After Surgery protocol between January 2017 and August 2020. Primary outcomes included LOS, and postoperative day (POD) 0-3 total opioids consumption measured by morphine milligram equivalents (MME). Multivariable linear or logistic models evaluated the association of TAP with outcomes while controlling for potential confounders.Results: Among 178 patients included in analysis, 84 patients underwent sTAP block and 94 did not. Multivariable analysis demonstrated significantly lower POD 0-3 total opioid usage (106.4 vs 192.2 MME, P = .004), and mean LOS (5.6 vs 7.7 days, P <.001) among the sTAP group.Conclusion: sTAP appears to be an effective adjunct to RC care associated with improved LOS, and POD 0-3 opioid consumption. Further studies are needed to optimize TAP block technique and anesthetic composition. [ABSTRACT FROM AUTHOR]

Objective: To examine the safety, feasibility and durability of robotic reimplantation of ureteroenteric stricture after radical cystectomy.Materials and Methods: A retrospective multi-institutional review was performed for all patients undergoing robotic repair of ureteroenteric stricture from January 2010 to January 2019. Functional outcomes and complications were followed and data were analyzed with SPSS statistical software.Results: A total of 46 patients and 58 renal units were identified, of which 15 had right sided, 19 left sided and 12 patients had bilateral strictures. Presentation of stricture was asymptomatic in 14 (30.4%) patients. Symptomatic presentations included infection in 22 (47.8%), worsening renal function in 11 (23.9%) and pain in 3 (6.5%) patients. Median time from cystectomy to diagnosis of stricture was 5 months (1-40). Median stricture length was 1.5 cm (range 0.5-10). All strictures were of benign etiology except for 4 (6.9%), which were due to malignancy. Overall, 49 (84.5%) ureters underwent primary re-implantation, while 9 (15.5%) required Boari-like advancement flaps prior to re-implantation. Median operative time was 190 min (range 45-540) with median estimated blood loss of 50 mL (range 25-2000) and median length of stay of 2 days (range 1-33, IQR 2-4). Seven (15.2%) patients experienced complications; 3 (6.5%) were low grade and 4 (8.7%) high grade. With median follow up of 18 months (range 1-51) the stricture recurrence rate was 8.6%.Conclusion: Robotic reimplantation of ureteroenteric strictures following radical cystectomy is safe and feasible in experienced centers with high success rates.

Objective: To evaluate long-term renal function following radical cystectomy (RC) for bladder cancer and identify risk factors associated with postoperative decline in renal function.Methods: The study included patients who underwent RC at a single centre in Denmark between 2009 and 2019. Data was collected through national electronic medical records. Renal function was evaluated by estimated glomerular filtration rate (eGFR) using pre- and postoperative creatinine measurements. Cumulative incidence and Cox Proportional Hazards models were used to describe the loss of renal function and its association with clinicopathological variables, as well as its effect on mortality.Results: After exclusions, 670 patients were eligible for analyses. Median follow-up time was 6.2 years (interquartile range 4.0 -8.4). The proportion of patients with renal insufficiency (eGFR<45 mL/min) increased from 8.9% before RC to 19% 5 years after surgery. A total of 610 patients with preoperative eGFR≥45 were included in survival analyses. The absolute risk of renal function decline to CKD stage G3b or worse (eGFR<45 mL/min) was 17% (95% CI 14 -20) at 5 years postoperatively. Loss of renal function was not significantly associated with higher all-cause mortality. In multivariate analysis lower preoperative eGFR, diabetes mellitus, prior pelvic radiation therapy, continent urinary diversion types, and postoperative ureteral stricture were all independently associated with renal function decline.Conclusion: The long-term renal function decreases considerably for a large number of RC patients. Recognizing preoperative risk factors could identify patients who benefit from enhanced renal surveillance or early intervention for modifiable factors to minimize renal insufficiency following RC.

A case of bladder necrosis in an 8-year-old female at time of presentation of ulcerative colitis (UC) is presented. A case of bladder necrosis in a pediatric patient outside of the neonatal period has not been reported. The patient presented with abdominal pain, bloody stools, hematuria, and acute renal failure. She was acutely management with bilateral nephrostomy tube placement. Bladder and colon biopsies revealed diagnosis of UC and bladder necrosis. The UC was medically managed. The bladder did not regenerate after several months of observation and ileal conduit urinary diversion was performed. A right proximal ureteral stricture was managed by pyeloplasty at time of ileal conduit. The patient is doing well over 1 year after surgery. [ABSTRACT FROM AUTHOR]

Objective: To compare perioperative and oncologic outcomes of intracorporeal (ICNB) and extracorporeal neobladder (ECNB) following robot assisted radical cystectomy (RARC) from a multi-institutional, prospectively maintained database, the International Robotic Cystectomy Consortium (IRCC).Methods: A retrospective review of IRCC database between 2003 and 2020 (3742 patients from 33 institutions across 14 countries) was performed (I-79606). The Cochran-Armitage trend test was used to assess utilization of ICNB over time. Multivariate logistic regression models were fit to evaluate variables associated with receiving ICNB, overall complications, high-grade complications, and readmissions after RARC. Kaplan Meier curves were used to depict recurrence-free, disease-specific, and overall survival.Results: Four hundred eleven patients received neobladder, 64% underwent ICNB. ICNB utilization increased significantly over time (P <.01). Patients who received ICNB were readmitted and received neoadjuvant chemotherapy more frequently (36% vs 24%, P = .03, 35% vs 8%, P <.01, respectively). ICNB was associated with older age (OR 1.04, 95% CI 1.01-1.07, P = .001), receipt of neoadjuvant chemotherapy (OR 4.63, 95% CI 2.34-9.18, P <.01), and more recent RARC era (2016-2020) (OR 12.6, 95% CI 5.6-28.4, P <.01). On multivariate analysis, ICNB (OR 5.43, 95% CI 2.34-12.58, P <.01), positive surgical margin (OR 4.88, 95% CI 1.29-18.42, P = .019), longer operative times (OR 1.26, 95% CI 1.00-1.58, P = .048), and institutional annual RARC volume (OR 1.09, 95% CI 1.05-1.12, P <.01) were associated with readmissions.Conclusion: Utilization of ICNB increased significantly over time. Patients who underwent RARC and ICNB had shorter hospital stays and fewer 30-d reoperations but were readmitted more frequently compared to those who underwent ECNB. [ABSTRACT FROM AUTHOR]

Objective: To determine whether use of an antibiotic-irrigating wound protector (AWP) reduces infectious complications after robotic radical cystectomy with extracorporeal urinary diversion (RCUD).Methods: A prospectively maintained bladder cancer database was queried for patients undergoing robotic RCUD at a tertiary referral center one year prior to implementing an AWP and one year after (2018-2020). All diversions were performed extra-corporally. 92 patients total. 46 consecutive patients using a traditional wound protector (TWP) and 46 consecutive with an AWP. Infections were classified as symptomatic urinary tract infection, blood stream infection, and surgical site infection. The incidence of infectious complications at 30- and 90-days were compared.Results: Baseline patient characteristics between the 2 groups showed no statistically significant differences. The overall complication rate was 65.2% in the TWP group and 26.1% in the AWP group at 30-days, and 67.4% vs 30.4% at 90-days. Focusing on infections, the 30-day complication rate was 30.4% in the TWP group compared to 6.5% in the AWP group (P =.003). This pattern persisted at 90-days with 37.0% in the TWP group compared to 6.5% in the AWP group (P =.004). Most complications were symptomatic UTI and blood stream infections, 14/24 (58%), requiring parenteral antibiotic treatment.Conclusion: We provide preliminary data showing use of an AWP can reduce infectious complications after RCUD. While larger prospective studies are warranted, our findings are a significant step towards decreasing morbidity of an already highly morbid procedure. [ABSTRACT FROM AUTHOR]

Objective: To improve the complications of traditional laparoscopic radical cystectomy (LRC), a novel technique of extraperitoneal laparoscopic radical cystectomy (ELRC) with preservation of fertility was described.Materials and Methods: Selected patients with bladder cancer were treated with the ELRC technique. The seminal vesicles and the vas deferens were preserved. Patient's perioperative conditions, tumor prognosis, and follow-up data were analyzed retrospectively.Results: We successfully completed ELRC surgery in dozens of patients. The orthotopic ileal neobladder was placed in the extraperitoneal area, completely preserving the peritoneum. The postoperative complications caused by postoperative peritoneal loss were reduced. Moreover, the perioperative period was strictly managed with the concept of enhanced recovery after surgery (ERAS). We described the operation process in detail through a typical case of a child. All patients were free of complication at short-term follow-up, and reported satisfied sexual function with normal erections.Conclusion: The ELRC technique has benefits in terms of decreased ileus, reoperation rates, hospital stay, ease of management of urinary leaks, and improves the patient quality of life. ELRC is also an oncologically safe approach with excellent significant functional outcomes in carefully selected transitional cell carcinoma (TCC) or non-TCC patients who expect to maintain sexual function and fertility, especially for young patients. In addition, more patient groups and longer follow-ups are needed to further understand the safety and practicality of the ELRC technology. [ABSTRACT FROM AUTHOR]

Objectives: To examine the durability of continent cutaneous catheterizable urinary channels (CCCC) in children and assess whether channel complications continue to arise with extended follow-up. Previous studies demonstrated that complications of CCCC cluster in the early years following surgery.Methods: The database of a tertiary center was queried for patients≤21 years who underwent CCCC. Patients with <6 years of follow-up were excluded. Patients were invited for follow-up to assess continence. Clinic visits and hospital admissions were reviewed for channel complications requiring reoperation. Complications were analyzed against patient and channel characteristics and time since initial surgery.Results: Between 1993 and 2012, a total of 120 patients underwent CCCC at a median age of 6.8(0.4-21) years and a median follow-up of 11.4(6.6-27) years. CCCC were created using the appendix, Monti channels and tapered ileal segments in 74(61.7%), 33(27.5%) and 13(10.8%), respectively. Continence relied on the extra-mural serous lined principle in 85.8% and the stoma was anastomosed to the umbilicus in 90%. Dryness with catheterization intervals of 3 hours or longer was eventually achieved in 90.8% with similar rates among different channel types (P=.149). 26(21.7%) required 42 interventions to treat channel complications with 32.5% occurring >5 years following initial surgery irrespective of the channel type (P=.978). On multivariate analysis, ileal channels had 3.372 higher odds of needing reoperation compared to appendicovesicostomy (95%CI=1.240-9.166; P = .037).Conclusion: A high reoperation rate is anticipated throughout the lifetime of CCCC. Appendicovesicostomy has a low complication risk relative to ileal channels. [ABSTRACT FROM AUTHOR]

Objective: To determine the durability of ureteroneocystostomy as well as pre- or post-operative factors that may be associated with failure to provide appropriate renal drainage.Methods: A total of 290 patients who underwent ureteral reimplantation to native bladder between 2003 and 2015 were identified. After excluding pediatric patients and those without any follow-up, 255 patients, 3 of whom had a subsequent contralateral reimplantation were included, for 258 observations. Kaplan-Meier method and univariate Cox models were used to assess whether factors such as radiation, prior abdominal surgery, age at re-implantation, gender and BMI are associated with re-implantation failure.Results: Among 258 observations, there were 27 failures. Median follow-up time was 1.1 years from re-implantation surgery among patients without a failure.1 and 5-year ureteral re-implantation failure is 7% (95% CI 4%, 12%) and 22% (95% CI 15%, 33%), respectively. On univariate analysis, post-operative radiation was found to be strongly associated with poorer ureteral re-implantation survival (HR: 6.62; CI 2.40, 18.29; P = .0003) No significant association between re-implantation failure-free survival and age at reimplantation, gender, BMI, previous abdominal surgery, preoperative radiation and adjuvant radiation was noted (all P > .4).Conclusions: Ureteroneocystotomy in the malignant setting has reasonable success rates through five years. No preoperative factors were associated with re-implantation failure. While all patients need to be followed due to increasing rates of failure with time, patients receiving palliative or salvage radiation therapy appear to be more prone to failure requiring further intervention.

Objective: To morphometrically measure to muscle mass which may reflect physical components of frailty. Hence, we evaluated the association between L4 total psoas area (TPA) and operative outcome after radical cystectomy (RC) for bladder cancer.Methods: In a retrospective single-center study, bladder cancer patients who underwent RC and urinary diversion between 2007 and 2012 were enrolled. TPA was evaluated in the cross-sectional imaging. The psoas muscles were normalized with the height. Male patients with a psoas mass index ≤7.4 cm2/m2 and female patients with a psoas mass index ≤5.2 cm2/m2 were classified as sarcopenic. Outcome measures were 30- and 90-day readmission and complications, and survival. Multivariable logistic and Cox proportional-hazards regression models were used to determine relevant predictors.Results: The median age of the 441 participants and follow up time was 68 years (IQR 59-75) and 1.2 years (IQR 0.5-1.9), respectively. One hundred forty-three patients (32.4%) were sarcopenic. The 30-day readmission and the complication rates were 13.8% and 44.7%, respectively. The 90-day readmission and complication rates were 23.9% and 53.1%, respectively. The 1-year mortality rate was 11.6% (95%CI 8.7-15.4). Multivariable logistic regression analysis revealed an association between increased TPA and lower odds of 30-day complications after RC (OR 0.95, 95%CI 0.92-0.99, P = .02); similarly, an increase in TPA was of prognostic value, although not statistically significant in the multivariable model (P = .05) once adjusting for other patient factors.Conclusion: Sarcopenia predicted early complications and showed an informative trend for overall survival after RC, and thus may inform models predicting postsurgical outcomes.

Vesicourethral anastomosis stenosis (VUAS) refers to the diameter narrowing of a vesicourethral anastomosis (VUA). It is a known complication after radical prostatectomy that nowadays presents in less than 1% of these cases. When the lumen narrows sufficiently to impede urine flow, obstructive symptoms arise. While the incidence of VUAS used to be notably higher prior to the widespread use of the robotic approach, traditional procedures still fail in up to 42% of cases. Initial management typically involves endoscopic procedures, such as dilation, incision, or resection. If these approaches prove ineffective, VUA reconstruction is warranted. Following the resection of the unhealthy urethra, a potential drawback is the insufficient length of the healthy proximal urethral to reach the bladder without tension. In such cases, urinary diversion with an ileal conduit is an option. However, when the patient prefers to maintain an orthotopic urinary tract configuration, there is limited guidance in the literature regarding surgical techniques. To outline the indications, describe the step-by-step technique, and evaluate the outcomes of transperineal urethral advancement to facilitate a tension-free VUA. We first discuss the indications to identify which patients are candidates for this procedure. Then, a step-by-step description of the robotic VUA revision assisted by transperineal urethral mobilization is presented. Detailed steps and helpful hints are included. Finally, we outline the postoperative pathway and expected outcomes. This technique allows patients with VUAS to preserve the orthotopic configuration of the urinary tract when a tension-free anastomosis proves challenging. Although urinary incontinence is expected, an artificial urinary sphincter could be placed in the following months. The robotic management of complex vesicourethral anastomosis stenosis with transperineal urethral advancement is a feasible and safe procedure that requires the interdisciplinary management of robotic and reconstructive urologists.

Objective: To demonstrate the surgical technique for prophylactic mesh placement in the sublay position during ileal conduit creation because literature suggests that prophylactic mesh placement at the time of cystectomy may reduce the risk of parastomal hernias with low risk of mesh-related complications. Parastomal hernias are one of the most common complications following ileal conduit construction and occur in 17-65% of patients undergoing cystectomy with urinary diversion. Review of our institutions data demonstrated a high incidence of hernias associated with ileal conduits, which have substantial burden to patients, surgeons, and the healthcare system.Methods: This is a retrospective chart review of data from a single surgeon who performed cystectomy with ileal conduit for 12 patients with bladder cancer between January, 2021-March, 2022 at our institution. These dates were chosen based on the timing of availability of literature suggesting a benefit from prophylactic mesh placement. Preliminary data was analyzed determine the incidence of parastomal hernia and mesh-related complications.Results: A total of 12 patients underwent cystectomy with ileal conduit between January, 2021-March, 2022 at our institution. Eleven patients (92%) had prophylactic mesh placed during their procedure. Median follow up was 5.4 months (0.8-8 months). Two patients (17%) developed a parastomal hernia which was detected clinically and/or radiographically. The hernias occurred in patients with mesh and within 6 months of cystectomy. One patient had stomal stenosis eventually requiring surgical revision. There were no mesh infections or mesh removals.Conclusion: Parastomal hernias are a common and morbid complication of ileal conduit urinary diversion. Our early experience demonstrates that the procedure is straightforward, adds little time to the surgical procedure, and is associated with a low complication rate. Our experience is too small and follow up too short to confirm that the results of the randomized trial can be matched at our center. [ABSTRACT FROM AUTHOR]

Objective: To report sexual health outcomes in male patients undergoing open radical cystoprostatectomy using a validated questionnaire.Materials and Methods: Beginning in 2017, male patients were asked to complete a validated questionnaire during scheduled post-cystectomy clinic visits that assessed sexual function using the 5 item International Index of Erectile Function (IIEF-5) and supplemental questions which evaluated libido, orgasm, partner interest, and adequacy of pre-operative counselling. Baseline data and functional outcomes were compared and multivariable analysis performed.Results: A total of 134 patients who met inclusion criteria completed the questionnaire. Pre-operative IIEF-5 was available in 78 patients with a median score of 16 (IQR:5-23). In those patients, median age at cystectomy was 68.9 years (IQR:60.2-72.4) and median duration of follow-up was 17.3 months (IQR:6.3-28.7). Median IIEF-5 score at time of survey completion was 1 (IQR:1-11). Increasing age, shorter follow-up duration, insufficient counselling, and absence of partner interest were predictive of lower scores. Younger age, pre-operative erectile function, and neurovascular preservation were predictive of a higher IIEF-5 score on univariate and multivariate analysis. Median libido score was 2 "low" (IQR:1-3) and ability to orgasm was reported by 34 (43.6%) patients. Neurovascular preservation (OR:3.03 95% CI:1.10-8.26, P = .03) and sufficient preoperative counselling (OR:3.078 95% CI:1.17-8.098, P = .02) were associated with preserved ability to orgasm. Libido was influenced by partner interest (OR 11.7, 95% CI:3.793-6.14, P <.0001).Conclusion: Sexual dysfunction after radical cystoprostatectomy is prevalent with many contributing factors. As such, establishing appropriate expectations and goals during preoperative counseling, performing neurovascular preservation when appropriate, and readily identifying and treating dysfunction in follow-up may improve sexual recovery.

Objective: To describe and illustrate a novel technique of uretero-ileal anastomosis for use in urinary diversion - the Pull-through Anastomosis of Ureter To Enteric Conduit (PAUTEC). A second objective was to evaluate the surgical outcomes of the PAUTEC anastomosis.Materials and Methods: Our novel anastomotic technique was described step-by-step and visually depicted with illustrations and the accompanying narrated video. Additionally, to evaluate safety and efficacy, a retrospective review of a prospectively maintained database was performed. Patients who underwent radical cystectomy alone or during pelvic exenteration, with ileal conduit diversion incorporating PAUTEC, 2016-2020 with ≥6 months follow-up were included. Surgical outcomes and renal function were analysed.Results: PAUTEC anastomosis was performed on 43 ureters in 23 patients. Mean age was 66 years [50-80] and 21 of 23 patients were male. One patient had a conservatively-managed small urine leak. No ureteric strictures have been identified to date. Mean serum creatinine was 1.15 mg/dL [0.69-2.08] (102umol/L, range 61-184 umol/L) preoperatively, and 1.09 mg/dL [0.61-2.59] (96.3 umol/L, range 54-229 umol/L) at follow-up, demonstrating no significant change (P= .26, paired t-test). Mean follow-up was 15 months [6-44].Conclusion: A PAUTEC technique of uretero-ileal anastomosis is feasible and technically straightforward, with satisfactory outcomes observed to date.
