OBJECTIVE To investigate the incidence, risk factors, and natural history of parastomal hernia. MATERIALS AND METHODS We reviewed the records of patients who underwent radical cystectomy and ileal conduit from 2007 to 2020. Patients who had available follow-up CT imaging were included in this study. All CT scans were re-reviewed for detection of parastomal hernia per Moreno-Matias classification. Patients who developed hernia were followed up and classified into stable or progressive (defined as radiologic upgrading and/or need for surgical intervention). Multivariable cox regression was performed to identify independent predictors of hernia development and progression. RESULTS A total of 361 patients were included in this study. The incidence of radiologic parastomal hernia was 30%, graded as I (56.5%), II (12%), and III (31.5%). Median (IQR) time to radiologic hernia was 8 (5-15) months. During the median (IQR) follow-up of 27 (13-47) months in 108 patients with a hernia, 26% progressed. Median (IQR) time to progression was 12 (6-21) months. On multivariable analysis, female gender (HR 1.86), diabetes (HR 1.81), chronic obstructive pulmonary disease (HR 1.78), and higher body mass index (HR 1.07 for each unit) were independent predictors for radiologic parastomal hernia development. No significant factor was found to be associated with hernia progression. CONCLUSION The incidence of radiologic parastomal hernia following radical cystectomy and ileal conduit is 30%; a quarter of whom progress in a median time of 12 months. Female gender, diabetes, chronic obstructive pulmonary disease, and high body mass index are independent predictors for radiologic hernia development.

Background Bladder cancer (BCa), the sixth commonest cancer in the USA, is highly lethal when metastatic. Spatial and temporal patterns of patient-specific metastatic spread are deemed random and unpredictable. Whether BCa metastatic patterns can be quantified and predicted more accurately is unknown. Objective To develop a web-based calculator for forecasting metastatic progression in individual BCa patients. Design, setting, and participants We used a prospectively collected longitudinal dataset of 3503 BCa patients who underwent a radical cystectomy following diagnosis and were enrolled continuously. We subdivided patients by their pathologic subgroup stages of organ confined (OC), extravesical (EV), and node positive (N+). We illustrated metastatic pathway progression using color-coded, circular, tree ring diagrams. We created a dynamical, data-visualization, web-based platform that displays temporal, spatial, and Markov modeling figures with predictive capability. Outcome measurements and statistical analysis Patients underwent history and physical examination, serum studies, and liver function tests. Surveillance follow-up included computed tomography scans, chest x-rays, and radiographic evaluation of the reservoir and upper tracts, with bone scans performed only if clinically indicated. Outcomes were measured by time to clinical recurrence and overall or progression-free survival. Results and limitations Metastases developed in 29% of patients (n = 812; median follow-up 15.3 yr), with 5-yr overall survival of 20.2%, compared with 78.6% in those without metastases (n = 1983; median follow-up 10.9 yr). The three commonest sites of spread at the time of first progression were bone (n = 214; 26.4%), pelvis (n = 194; 23.9%), and lung (n = 194; 23.9%). The order and frequency of these sites vary when divided by pathologic subgroup stages of OC (lung [n = 65; 25.1%], urethra [n = 45; 17.4%], and bone [n = 29; 11.2%]), EV (pelvis [n = 63; 33.0%], bone [n = 45; 23.6%], and lung [n = 29; 15.2%]), and N+ (bone [n = 111; 30.7%], retroperitoneum [n = 70; 19.3%], and pelvis [n = 60; 16.6%]). Markov chain modeling indicated a higher probability of spread from bladder to bone (15.5%), pelvis (14.7%), and lung (14.2%). Conclusions Our web-based calculator allows real-time analyses in the clinic based on individual patient-specific demographic and cancer data elements. For contrasting subgroups, the models indicated differences in Markov transition probabilities. Spatiotemporal patterns of BCa metastasis and sites of spread indicated underlying organotropic mechanisms in the prediction of response. This recognition opens the possibility of organ site–specific therapeutic targeting in the oligometastatic BCa setting. In the precision medicine era, visualization of complex, time-resolved clinical data will enhance management of postoperative metastatic BCa patients. Patient summary We developed a web-based calculator to forecast metastatic progression for individual bladder cancer (BCa) patients, based on the clinical and demographic information obtained at diagnosis. This can help in predicting disease status and survival, and improving management in postoperative metastatic BCa patients. Take Home Message Future pathways of metastatic progression for individual bladder cancer patients can be determined based on currently available clinical and demographic information obtained at diagnosis. In focused subgroups of patients, these metastatic spread patterns can also portend disease status and survival.

Radical cystectomy (RC) is a complex procedure associated with lengthy hospital stays and high complication and readmission rates. We evaluated the impact of patient, surgical, and perioperative factors on discharge disposition following RC at a tertiary referral center. From 2012 to 2019, all bladder cancer patients undergoing RC at our institution were identified (n = 1153). Patients were classified based on discharge disposition: to home or to continued facility-based rehabilitation centers (CFRs, n = 180 (15.61%) patients). On multivariate analysis of patient factors only, age [Risk Ratio (RR): 1.07, p < 0.001)], single marital status (RR: 1.09, p < 0.001), and living alone prior to surgery (RR: 2.55, p = 0.004) were significant predictors of discharge to CFRs. Multivariate analysis of patient, surgical, and perioperative factors indicated age (RR: 1.09, p < 0.001), single marital status (RR: 3.9, p < 0.001), living alone prior to surgery (RR: 2.42, p = 0.01), and major post-operative (Clavien > 3) complications (RR: 3.44, p < 0.001) were significant independent predictors of discharge to CFRs. Of note, ERAS did not significantly impact discharge disposition. Specific patient and perioperative factors significantly impact discharge disposition. Patients who are older, living alone prior to surgery, and/or have a major post-operative complication are more likely to be discharged to CFRs after RC.

To evaluate perioperative and functional outcomes of radical cystectomy (RC) and urinary diversion (UD) in patients with a single kidney (SK) vs. double kidneys (DK).We reviewed records of patients who underwent RC for bladder cancer with a history of prior or concurrent nephrectomy at USC between 2004 and 2020. Patients with chronic kidney disease who were already on dialysis were excluded. UD, perioperative complications, and postoperative glomerular filtration rate (GFR) of the SK group were compared with a group of patients who underwent RC with DK using 2:1 matching with respect to age, sex, preop GFR, and tumor stage.We included 186 patients (SK = 62 and DK = 124). Half of the SK patients underwent continent UD. SK patients had a higher length of hospital stay compared to the DK group; however, 90-day complications, readmission, and mortality rates were similar. In patients with continent diversion, SK vs. DK showed similar 90-day complications (71% vs. 69%, P = 1.0). SK patients had significantly lower GFRs at discharge, 3-, and 12-month following RC compared to the DK group. Postoperative GFRs of the SK patients with continent vs. incontinent UD were statistically similar. On multivariable analysis, UD (i.e. continent vs. incontinent) was not associated with post-op GFR decline at discharge, 3- and 12-month following RC.Perioperative outcomes of radical cystectomy patients with single kidney are similar to double kidney patients, except for more GFR decline in single kidney cases. Continent urinary diversion in single kidney is as safe as double kidney patients.

OBJECTIVES To evaluate the complications and oncologic outcomes of orthotopic ileal neobladder reconstruction (ONB) following pelvic radiotherapy (RT) compared to patients with no prior pelvic RT. METHODS Our institutional database was queried for all patients with pT0-4bN0-3M0 urothelial carcinoma of the bladder who underwent radical cystectomy with curative intent and ONB between 1990 and 2018. We then queried this cohort for patients who had prior pelvic RT (>3900 cGy) and compared baseline characteristics, perioperative complications, and recurrence free survival between patients with and without prior pelvic RT. RESULTS One thousand eight hundred and forty-six patients matched our inclusion criteria; 34 had prior pelvic RT with a median dose of 6280 cGy. Prior RT targeted the bladder, prostate, and cervix in 27, 6, and 1 patient, respectively. Median time from RT to cystectomy was 15.5 months. Patients with prior RT had a longer time from diagnosis to cystectomy, more frequently had ≥5 TURBT and neoadjuvant chemo, and less frequently had multifocal disease. Perioperative complications including operative time, estimated blood loss, days hospitalized, as well as 30- and 90-day complication rates, were not statistically different. There was no statistical difference in recurrence free survival between the 2 groups (P = .48). CONCLUSION ONB in highly selected patients with prior pelvic RT is feasible with statistically similar perioperative complication rates compared to ONB without prior RT.

To develop an easy tool to predict cancer specific (CSS) and disease-free survival (DFS) in patients with bladder cancer treated with radical cystectomy.Data from a consecutive series of 2395 patients with primitive or progression to muscle invasive bladder cancer (MIBC) undergone to radical cystectomy and lymph nodes dissection in 5 centers were evaluated. Using Cox proportional hazards analyses, the Cancer of the bladder risk assessment (CRAB) nomogram was generated. Accuracy of the nomogram was evaluated by Harrell's C test. Internal validation of the model was performed using 200 bootstraps.Median age was 66 (IQR 58/73) years; 612/2395 (26%) patients presented an advanced pathological stage (≥pT3a); 478/2395 (20%) presented positive lymph nodes. Overall, 729/2395 (30%) presented local or distant recurrence with a median DFS of 42 (IQR 14/89) months. Overall, 642/2395 (27%) died of bladder cancer with a median follow up of 48 (IQR 22/92) months. On univariate Cox proportional hazards analyses, age, stage, and lymph nodes density were a significant predictor of 3 and5 years CSS and DFS. Accuracy of the CRAB nomogram was 0.73 and 0.71 respectively.CRAB nomogram can be a practical and easily applicable tool that may help urologists to classify the long-term CSS and DFS of patients treated with radical cystectomy and to predict the oncological outcome.

Objectives To describe the feasibility and perioperative outcome of suprarenal resection of inferior vena cava (IVC) in urologic neoplasms without reconstruction. Methods We retrospectively reviewed the patients who underwent suprarenal resection of IVC without reconstruction for urologic neoplasms in our institution between September 2010 and October 2019. Patients’ demographic, clinical, radiologic, and 90-day perioperative complications were recorded. Results Twenty-eight (79% male) patients with a median age of 59 (25-75) years were included in the study. Twenty-five (89%) of patients had renal cell carcinoma, one had renal leiomyosarcoma, and two had metastatic testicular teratoma. Twenty-two patients had Mayo level 3 thrombus, three had level 2 and three had level 4. The mean radiologic thrombus length was 12.6 cm. Eleven patients had radiologic bland thrombosis in the infrarenal IVC. Twenty-seven patients underwent open, and one robotic surgery. The median operating time was 411 (range 240-808) minutes, median blood loss was 3750 cc, and all but one patient received perioperative transfusion (median 11 units of packed red blood cells). Median hospital stay was 5 (3-50) days. 90-day complication rate was 35% (Clavien-Dindo grade I/II and III/IV were 21% and 14%, respectively). Four patients (14%) developed transient non-disabling leg edema. The 90-day mortality rate was 7%. Conclusions Suprarenal inferior vena cava resection without reconstruction is feasible, yet high-risk operation that should be performed in experienced centers in selected patients with urologic malignancies.

To evaluate three subtypes of continent-cutaneous urinary diversion (CCUD); Indiana pouch (IP), right colon pouch with appendico-umbilicostomy (AU), and right colon pouch with neo-appendico-umbilicostomy (NAU), by investigating diversion-specific complications and quality-of-life outcomes.A retrospective review of an IRB-approved database was conducted for perioperative and outcome data. The EORTC QLQ-C30 questionnaire was used to assess quality of life; all responses were obtained 6 months after diversion.Fifty-eight patients who underwent a CCUD at our institution from 2010 to 2016 (33 IP by two surgeons, 15 AU and ten NAU by third surgeon) were identified for this study. Higher age and Charlson Comorbidity Index (CCI) ≥ 3 were seen in the AU cohort when compared to the IP cohort (P = 0.02 and 0.02, respectively). NAU group were also older when compared to the IP group (P = 0.02). After a median follow-up of 21 months (range: 0.8-81.0), more high-grade diversion-related complications were reported for AU and NAU patients comparing to the IP group (P 0.01 and P = 0.02, respectively). More stoma complications were also reported for the NAU cohort than the IP cohort (70% vs 30%, P = 0.03). In all groups, 60% of stoma complications occurred at the skin or fascia level. In the 90-day postoperative period, a higher continence rate was reported for the IP cohort, and this difference was significant when compared to the NAU cohort (P = 0.04). Length of stay after surgery and revision rates were not significantly different. For all groups, the majority of patients reported little-to-no disturbance of daily functions and rated overall quality of life as good-to-excellent.Urinary diversion using the Indiana pouch and right colon pouch with appendico/neo-appendico-umbilicostomy are all associated with high rates of continence and patient satisfaction. When compared to IP, AU and NAU patients had higher rates of high-grade diversion-related complications and NAU patients had a higher stoma complications with lower 90-day continence rate.

574 Background: To evaluate how the location of bladder cancer recurrence after radical cystectomy (RC) affects survival and assess the role of salvage immunotherapy in this setting. Methods: On retrospective review of 4093 patients from our institutional IRB approved cystectomy database from January 1971 to December 2021, we identified 889 patients who underwent RC with curative intent and have been detected with recurrence of bladder cancer. Patients with urethral and ureteral recurrence were excluded. The data was then stratified based on the site of recurrence. Results: In this cohort of 889 patients (median age of 68, 77% male), the most common sites of metastases were widespread (48%), local (15%), lung (10%), bone (8%), retroperitoneal nodes (5.5%), liver (5%) and brain (1.5%) in order. With a median of 8.4 months, bone metastasis had shortest length from cystectomy to recurrence, while liver metastasis had shortest post recurrence survival (median of 4 months). For distant recurrence alone, only 33% survived past the first year. Salvage immunotherapy was administered in 8% of the patients and 47% received salvage chemotherapy. On multivariate analysis, liver metastasis (HR 2, 95%CI 1.4-2.9), widespread metastasis (HR 1.9, 95%CI 1.5-2.4), pathological staging>T3 (HR 1.3, 95%CI 1.1-1.6) and nodal involvement at the time of RC (HR 1.5, 95%CI 1.2-1.7) were significantly associated with worse survival after the recurrence. Salvage immunotherapy provided a significant improvement in post-recurrence survival (HR 0.2, 95% CI 0.1-0.3). Conclusions: Liver, brain, and widespread metastases predominantly showed the lowest chance of survival past one year from recurrence; however, more than half of all patients with recurrence did not live past the first year. Salvage immunotherapy may lead to a better prognosis in recurrence post-cystectomy. [Table: see text]

To examine the oncological outcomes and recurrence patterns in patients with no residual disease at the time of radical cystectomy (RC).A retrospective review of our IRB-approved bladder cancer database identified patients who underwent RC between 2000 and 2019 and were found to have no residual disease (pT0N0), either following neoadjuvant chemotherapy (NAC) or transurethral resection (TURBT) alone. The primary outcome was recurrence-free survival (RFS). Regression models assessed factors influencing recurrence, and a detailed description of recurrence patterns was compiled.From a total of 2222 patients, 234 (10.5%) were included with a median age of 67 years. NAC was used in 89 (38%) patients and 145 (62%) cases were rendered pT0 following TURBT alone. At a median follow-up of 44 months, there were 16 (6.8%) recurrences, 10 (63%) of which occurred in the ypT0 group. None of the patients with clinical Ta/Tis disease had a recurrence after RC. The median time to recurrence was 9 months. Ninety-one percent (10/11) of recurrences in the ypT0 group were within 2 years of cystectomy, while half of the recurrences in the pT0 group occurred after 2 years. Patients with ypT0 had worse 2- and 5-year RFS compared to the pT0 group (85% and 84% vs. 99% and 95%, respectively; P = 0.003). Variant histology was noted in 49 (21%) patients; the recurrence rate was higher in this subgroup compared to those with pure urothelial carcinoma (12.2% vs. 5.4%, P = 0.02). Lung metastasis and involvement of distant organs, while rare, were noted at similar rates in both groups.Patients with pT0N0 pathology at the time of cystectomy should prudently undergo long-term surveillance as recurrence and metastasis can still develop up to 4 years after surgery. Patients achieving ypT0 after NAC exhibit worse prognosis and shorter times to recurrence, closer follow-up may be considered.

To examine the effect of diagnostic ureteroscopy (URS) and ureteral access sheath usage on bladder recurrence following radical nephroureterectomy (RNU).We retrospectively reviewed the records of patients who underwent RNU between 2005 - 2019. Patients with a history of bladder cancer and those without a bladder cuff resection were excluded. Bladder recurrence was the primary outcome and cox regression modeling was used to assess the impact of URS adjusting for other factors.Out of 271 RNU cases, 143 were included with a median age of 73 years (IQR 65 - 80). URS was performed in 104 cases (73%) and a ureteral access sheath was used in 26 (25%). With a median follow-up of 27 months, there were 36 (25%) bladder recurrences. The bladder recurrence rate (median time to recurrence) for patients who had URS vs no URS was 30.8% (9.0 months) and 7.7% (12.1 months), respectively (P = .02). A lower recurrence rate was noted in patients whom a ureteral access sheath was utilized (11.5%) vs those with no access sheath (39.7%, P = .01). Multivariable analysis revealed a significant increase in bladder recurrence if URS was performed prior to RNU (HR 5.6 [1.7 - 18.5], P.004), however, this effect was mitigated if a ureteral access sheath was used (HR 1.3, [0.3 - 6.4], P = .76). Ureteral stent usage and performing a ureteroscopic biopsy had no significant effect on bladder recurrence.Diagnostic URS in patients undergoing RNU for UTUC significantly increases the risk of bladder recurrence. This effect may be mitigated by using a ureteral access sheath.

PURPOSE: Conventional imaging cannot definitively detect nodal metastases of prostate cancer. We histologically validated (11)C-acetate positron emission tomography/computerized tomography to identify nodal metastases, examining prostate cancer factors that influence detection rates. MATERIALS AND METHODS: Patients with (11)C-acetate avid positron emission tomography/computerized tomography imaged pelvic/retroperitoneal lymph nodes underwent high extended robotic lymphadenectomy. A standardized mapping template comprising 8 predetermined anatomical regions was dissected during lymphadenectomy, allowing for matched, region based analysis and comparison of imaging and histological data. RESULTS: In 25 patients a total of 2,149 lymph nodes were excised (mean 86 per patient, range 27 to 136) and 528 (22%) harbored metastases (mean 21 positive nodes per patient, range 0 to 109). A total of 174 anatomical regions had matching imaging histological data. (11)C-acetate positron emission tomography/computerized tomography accurately identified 48 node-positive regions and accurately ruled out 88 regions as metastasis-free. (11)C-acetate sensitivity, specificity, and positive and negative predictive values were 67%, 84%, 74% and 79%, respectively. An increasing, histologically measured metastatic lesion size in long axis diameter of 5 or less, 6 to 10, 11 to 15, 16 to 20 and 21 mm or greater correlated with improved (11)C-acetate detection rates of 45%, 62%, 81%, 89% and 100%, respectively. Each standard uptake value unit increase correlated with a 1.9 mm increase in nodal long axis diameter (p

INTRODUCTION AND OBJECTIVES: We previously reported that elevated precystectomy serum levels of epithelial tumor markers predict worse oncological outcome in patients with invasive bladder cancer (BC). Herein, we evaluated the effect of neoadjuvant chemotherapy (NAC) on elevated tumor marker levels and their association with oncological outcomes. METHODS: Under IRB approval, serum levels of Carbohydrate Antigen 125 (CA-125), Carbohydrate Antigen 19-9 (CA 19-9) and Carcinoembryonic Antigen (CEA) were prospectively measured in 480 patients with invasive BC from August 2011 through December 2016. In the subgroup undergoing NAC, markers were measured prior to the first and after the last cycle of chemotherapy (prior to cystectomy). RESULTS: Three hundred and thirty-seven patients were eligible for the study, with a median age was 71 years (range 34–93) and 81% (272) male. Elevated precystectomy level of any tumor markers (31% of patients) was independently associated with worse recurrence-free survival (hazard ratio [HR] = 2.81; P < 0.001) and overall survival (HR = 3.97; P < 0.001). One hundred and twenty-five (37%) patients underwent NAC, of whom 59 had a complete tumor marker profile and 30 (51%) had an elevated pre-NAC tumor marker. Following completion of chemotherapy, 10/30 (33%) patients normalized their tumor markers, while 20/30 (67%) had one or more persistently elevated markers. There was no difference in clinical or pathological stage between groups (P = 0.54 and P = 0.09, respectively). Further analysis showed a significantly lower rate and longer median time to recurrence/progression in the responder group (50% in responders vs. 90% in nonresponders at a median time of 22 vs. 4.8 months, respectively; P = 0.015). There was also significant difference in mortality rates and median overall survival between the study groups (30% in responders vs. 70% in nonresponders at a median time of 27.3 vs. 11.6 months respectively; P = 0.037). Two of the three patients that died in the normalized tumor marker group had tumor marker relapse at recurrence prior to their death. CONCLUSIONS: To our knowledge, this is the first study showing tumor marker response to NAC. Patients with persistently elevated markers following NAC have a very poor prognosis following cystectomy, which may help identifying chemotherapy-resistant tumors. A larger, controlled study with longer follow up is needed to determine their role in predicting survival.

Objective: To assess predictors of discharge disposition—either home or to a CRF—after undergoing RC for bladder cancer in the United States. Methods: In this retrospective, cohort study, patients were divided into two cohorts: those discharged home and those discharged to CRF. We examined patient, surgical, and hospital characteristics. Multivariable logistic regression models were used to control for selected variables. All statistical tests were two-sided. Patients were derived from the Premier Healthcare Database. International classification of disease (ICD)-9 (

Introduction: The aim of this study was to evaluate the outcomes of radical cystectomy with an enhanced recovery after surgery (ERAS) protocol in patients with a history of chronic preoperative narcotic use compared to narcotic-naive patients. Methods: We identified 553 patients who underwent open radical cystectomy with ERAS. Preoperative narcotic use was identified in 34 patients who were then matched to 68 narcotic-naive patients. Postoperative outcomes, opioid use, and visual analog scale (VAS) pain scores were analyzed and compared. All routes of opioid use were recorded and converted to a morphine equivalent dose (MED). Results: Patients with preoperative narcotic use reported higher median VAS pain scores per day (POD1: 5.2 vs. 3.9, p=0.003; POD2: 5.1 vs. 3.6, p

The aim of this study is to evaluate the intra/perioperative fluid management and early postoperative outcomes of patients who underwent radical cystectomy with Enhanced Recovery After Surgery protocol, using goal-directed fluid therapy compared to conventional fluid therapy. This cohort study included patients who underwent open RC for urothelial bladder carcinoma with intent to cure and Enhanced Recovery After Surgery protocol between May 2012 and August 2019. Patients who had palliative or salvage cystectomy and/or adjunct procedures, as well as those with missing detailed perioperative data were excluded. Data were compared between patients who received goal-directed fluid therapy using stroke volume variation by FloTrac™/Vigileo system (n = 119) and conventional fluid therapy based on the anesthesiologist discretion (n = 192). Primary outcome variable was 90-day complications and secondary outcome measures included in-hospital GFR trend, length of stay, and 90-day readmission. The goal-directed fluid therapy group received less total and net intra/perioperative fluid, yet early postoperative glomerular filtration rate trends were similar between both groups (p = 0.7). Estimated blood loss, blood transfusion, index hospital stay, 90-day complication and readmission rates were also comparable between the two groups. Multivariable logistic regression showed no significant association between perioperative fluid management method and 90-day complication rate (OR 1.4, 95% CI 0.8–2.4, p = 0.2). Stroke volume variation guided goal-directed fluid therapy is safe in radical cystectomy without compromising the renal function. It is associated with less intra- and perioperative fluid infusion; however, no association with hospital stay, 90-day complication or readmission rates were noted.

Background Recently, the Cancer of the Bladder Risk Assessment (COBRA) score has been introduced to estimate cancer specific survival (CSS) after radical cystectomy for bladder cancer. Objectives Aim of our study was to validate the COBRA score, assessing the effect of age, tumor stage and lymph-nodes status on CSS after cystectomy in patients with bladder cancer. Design, setting, and participants A consecutive series of 2395 patients with primitive or recurrent bladder cancer treated with radical cystectomy in 4 centers were evaluated. Outcome measurements and statistical analysis The role of COBRA score as predictor of CSS was assessed using the Kaplan Meier and Cox proportional hazards analyses. Accuracy of COBRA score was evaluated by Harrell's C test. Results and limitations Median age was 66 (IQR 58/73) years. Overall, at a median follow-up of 48 (IQR 22/92) months, 642 patients (27%) died of bladder cancer. On Cox proportional hazards analyses, COBRA score was a significant predictor of CSS (HR 1.54, 95%CI 1.47–1.61) (Table 1). The predictive accuracy of the COBRA score was 0.71. A sub analysis including pooled COBRA score (0 vs 1–3 vs 4 vs 5–7) improved the clinical applicability with the same accuracy. Conclusion In our experience, the COBRA score is an excellent tool to predict cancer specific survival. The COBRA Score represents a practical and easy tool that may help urologists to classify the CSS of patients treated with radical cystectomy, to predict the oncological outcome and finally to counsel bladder cancer patients.

We examine the timing, patterns and predictors of 90-day readmission after robotic radical cystectomy.From September 2009 to March 2017, 271 consecutive patients undergoing robotic radical cystectomy with intent to cure bladder cancer (intracorporeal diversion 253, 93%) were identified from our prospectively collated institutional database. Readmission was defined as any subsequent inpatient admission or unplanned visit occurring within 90 days from discharge after the index hospitalization. Multiple readmissions were defined as 2 or more readmissions within a 90-day period. Logistic regression analysis was used to identify independent factors related to single and multiple 90-day readmissions.A total of 78 (28.8%) patients were readmitted at least once within 90 days after discharge, of whom 20 (25.6%) reported multiple readmissions. The cumulative duration of readmission was 6.2 (6.17) days with 6 (7.6%) patients having less than 24 hours readmission. Metabolic, infectious, genitourinary and gastrointestinal complications were identified as the primary cause of readmission in 39.5%, 23.5%, 22.3% and 17%, respectively. Fifty percent of readmissions occurred in the first 2 weeks after hospital discharge. On multivariable logistic regression analysis in-hospital infections (OR 2.85, p=0.001) were independent predictors for overall readmission. Male gender (OR 3.5, p=0.02) and in-hospital infections (OR 4.35, p=0.002) were independent predictors for multiple readmissions.The 90-day readmission rate following robotic radical cystectomy is significant. In-hospital infections and male gender were independent factors for readmission. Most readmissions occurred in the first 2 weeks following discharge, with metabolic derangements and infections being the most common causes.

Objectives To investigate the prevalence of catheterisation and urinary retention in male patients with bladder cancer after radical cystectomy (RC) and orthotopic neobladder (ONB) and to identify potential predictors. Patients and methods Using an Institutional Review Board approved, prospectively maintained bladder cancer database, we collected information using a diversion-related questionnaire from 299 consecutive male patients with bladder cancer upon postoperative clinic visit. Urinary retention was defined as ≥3 catheterisations/day or a self-reported inability to void without a catheter. Uni- and multivariable Cox regression analysis was performed to identify predictors of catheterisation and urinary retention. Results Self-catheterisation was reported in 51 patients (17%), of whom, 22 (7.4% of the total patients) were in retention. Freedom from any catheterisation at 3, 5, and 10 years after RC was 85%, 77%, and 62%, respectively. Freedom from retention at 3, 5, and 10 years after RC was 93%, 88%, and 79%, respectively. Multivariable Cox regression showed that higher body mass index (BMI; ≥27 kg/m2 ) significantly increased the need for catheterisation (hazard ratio [HR] 2.34, 95% confidence interval [CI] 1.26-4.32) as well as retention (HR 5.20, 95% CI 1.74-15.51). Greater medical comorbidity (Charlson Comorbidity Index score ≥2) correlated with the need for any catheterisation (HR 1.84, 95% CI 1.02-3.3), but not retention. Pathological stage and type of diversion were not significant predictors of the need to catheterise or urinary retention. Conclusion In males undergoing RC with ONB, retention requiring catheterisation to void is uncommon. Patients with a BMI of ≥27 kg/m2 are at significantly increased risk of retention and need for self-catheterisation.
