Purpose To present the outcomes of revascularized pyeloureterocystoplasty with ureterocele unroofing in end stage bladder patients with duplex system and ureterocele. Methods Thirteen patients with obstruction of intrauterine outlet from an ectopic obstructive ureterocele were included. Fourteen units of duplex systems underwent upper pole partial nephrectomy in conjunction with augmentation revascularized pyeloureterocystoplaty and ureterocele unroofing. The anterior and lateral walls of the ureterocele were excised before cystoplasty, and the resultant edges of the posterior wall were sutured to the bladder epithelium. Anastomosis of the upper pole vein and artery to the inferior iliac artery and the common iliac vein was performed. Detubularization of the whole ureter was performed with exception of the intramural ureteric part that kept tubularized for ‘jet/turbulent’ occurrence. Five patients (control group) underwent pyeloureterocystoplasty without revascularization. Patients underwent several evaluations in long-term follow-up. Results Patients were all dry by day and night in our long-term follow-up. Urinary incontinence improved in patients with no need for re-augmentation technique. Vesicoureteral reflux subsided in all patients postoperatively except one, who was asymptomatic. After five years, median bladder capacity rose from 128.5 ml to 395 ml and bladder compliance showed significant improvement from 15 ml/cm H2O to 29 ml/cm H2O, in experimental group and remained stable for 24–36 months. Median bladder capacity did not rise significantly in control group. Conclusion Pyeloureterocystoplasty is an efficient choice in this type of patients, which may prevent the recurrence of hypocompliant bladders and prevent ischemia and subsequent fibrosis.

Purpose: This study aims to evaluate the long-term outcome of the serous-lined extramural continent catheterizable outlet procedure (SLECCOP) associated with ileal bladder augmentation in children., Methods: This was a monocentric and retrospective study (2002-2021) that included children (<18 years) undergoing the SLECCOP associated with W-shaped ileocystoplasty with a catheterizable channel (Abol-Enein and Ghoneim procedure). Patients who received other types of bladder augmentation or W-shaped ileocystoplasty without a catheterizable channel were excluded. Patient records were reviewed for demographic information, surgical data, and long-term outcomes., Results: This study included 52 children [33 boys, median age: 8.5 (0.8-18) years]. Pathological conditions included 28 children with the bladder exstrophy and epispadias complex (BEEC), 11 with neurogenic bladders, and 13 with other pathologies. Two patients underwent total bladder substitution. Thirty-four (65%) patients had bladder neck reconstruction (BNR), with 23 undergoing the SLECCOP and ileocystoplasty and 11 having prior BNR. All stomas, except for two, were umbilical, and were associated with omphaloplasty in 28 patients with the BEEC. A total of 40 stomas were created using the appendix (77%) and 12 with a Monti tube (23%). Stoma-related complications included cutaneous strictures ( n  = 2, 4%) and leaks ( n  = 10, 19%), all treated by dextranomer/hyaluronic acid copolymer injection ( n  = 10). A redo surgery was required in three patients: extraserosal wrapping was performed for persistent leakage ( n  = 2, 4%), and surgical revision was required for the Monti tube procedure ( n  = 1, 2%). Three patients (6%) underwent dilatation for transient stoma stenosis. Leakage occurred in 20% of appendix channels ( n  = 8/40) and 17% of Monti tubes ( n  = 2/12). Strictures were reported in 3% of appendix channels ( n  = 1/40) and 8% of Monti tubes ( n  = 1/12). Bladder stones developed in four patients (8%). Channel leakage persisted in one patient (2%) at a median follow-up of 4.4 years (IQR 1.4-9.7)., Conclusion: W-Ileal bladder augmentation with the SLECCOP is an efficient technique for treating children with incontinence caused by different etiologies. The rate of channel complication is very low, specifically for strictures, in this complex population of patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Alliot, Tapsoba, Paye-Jaouen, Ashkanani, Josset-Raffet, Natio, Peycelon and El-Ghoneimi.)

A 65-year-old male with a history of urinary tract trauma requiring cystotomy and chronic bladder catheterization, presenting with chronic and uninvestigated changes in the color of the urine bag system, with no urine color change, and positive urine culture for Proteus mirabilis. These characteristics refer to the purple urine bag syndrome, a not well-known condition, with a benign course in most cases, and associated with urinary tract infection in patients with chronic bladder catheterization. Although it is characterized by marked changes, it is underdiagnosed by healthcare professionals. [ABSTRACT FROM AUTHOR]

Neuropathic bladder usually causes several limitations to patients’ quality of life, including urinary incontinence, recurrent urinary tract infections, and upper urinary tract damage. Its management has significantly changed over the last few years. The aim of our paper is to address some salient features of recent literature dealing with reconstructive procedures in pediatric and adolescent patients with lower urinary tract dysfunction.

Purpose Robotic intracorporeal urinary diversion has mostly been done for ileal conduit or orthotopic neobladder diversion. We present what is to our knowledge the initial series, detailed technique and outcomes of the robotic intracorporeal Indiana pouch with a minimum 1-year followup. Materials and Methods Ten patients underwent robotic radical cystectomy, pelvic lymphadenectomy and intracorporeal Indiana pouch urinary diversion for cancer in 9 and benign disease in 1. Data were collected prospectively. Baseline demographics, pathology data, and 1-year complication rates and functional outcomes were assessed. Results All 10 cases were successfully completed intracorporeally without open conversion. Median total operative time was 6 hours, including 3.5 hours for pouch creation. Median blood loss was 200 cc and median hospital stay was 10 days. Four Clavien grade 1-2 and 3 Clavien 3-5 complications occurred. None of the patients had a bowel leak. One noncompliant patient requested undiversion to an ileal conduit. The remaining 9 patients successfully catheterized the ileal channel and were completely continent at the last followup at a median of 13.7 months (range 12.3 to 15.2). Study limitations include small sample size and short followup. Conclusions We present what is to our knowledge the initial series of robotic completely intracorporeal Indiana pouch diversion. Early perioperative data indicate acceptable operative efficiency and complication rates. Longer followup is required to assess the functional outcomes of this less commonly performed diversion.

Objective To compare the erectile function (EF) and sexual desire (SD) in men after radical cystoprostatectomy (RCP) who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. Materials and Methods Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41) or orthotropic ileal neobladder substitution (n = 40). EF and SD were assessed using International Index of Erectile Function (IIEF) questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. Results Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006). At 12-month postoperative period, 4 (9.8%) and 14 (35.0%) patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006). Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8%) and 7 (17.1%) patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02). At 12-month follow up period 24.4% of the ileal conduit and 45.0% of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01). Conclusion When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

INTRODUCTION: We performed a laparoscopic radical cystoprostatectomy followed by constructing a Y-shaped reservoir extra-corporeally with titanium staples through a 5-cm muscle-splitting Pfannenstiel incision. SURGICAL TECHNIQUE: Upon completion of the extirpative part of the operation, the surgical specimen was entrapped and removed intact through a 5-cm Pfannenstiel incision. Through the extraction incision, the distal ileum was identified and a 40 cm segment isolated. With the aid of the laparoscope, the ureters were brought outside the abdominal cavity and freshened and spatulated for approximately 1.5-cm. Bilateral double J ureteral stents were then inserted up to the renal pelvis and the ureters were directly anastomosed to the open ends of the limbs of the neobladder. Following this, the isolated intestinal segment was arranged in a Y shape with two central segments of 14 cm and two limbs of 6 cm. The two central segments were brought together and detubularized, with two sequential firings of 80 x 3.5 mm and 60 x 3.5 mm non-absorbable mechanical stapler (Multifire GIA - US Surgical) inserted through an opening made at the lowest point of the neobladder on its anti-mesenteric border. The neobladder was reinserted inside the abdominal cavity and anastomosed to the urethra with intracorporeal laparoscopic free-hand suturing. CONCLUSION: Although this procedure is feasible and the preliminary results encouraging, continued surveillance is necessary to determine the lithiasis-inducing potential of these titanium staples within the urinary tract.

OBJECTIVE: To research technical alternatives for permanent gastrostomy that minimizes the drawbacks and complications reported by several authors. MATERIALS AND METHODS: An experimental model was developed where the material was divided into 2 groups: the study group (SG) composed of 12 half-breed dogs where the proposed technique was applied, and the control group (CG) composed of 10 animals where a gastrostomy as proposed by Webster in 1974 was applied. On the 90th postoperative day, both groups underwent tests for assessing competence concerning leakage. These were performed under general anesthesia and following sacrifice. RESULTS: In the SG, under anesthesia only one animal had leakage through the gastrostomy. Following sacrifice, leakage was observed in 2 animals. In the CG, under anesthesia, 2 animals had leakage and, following sacrifice, only 1 animal did not present leakage. On histopathological analysis of the SG, gastric mucosa was evidenced around the jejunal tubes, with normal features, moderate inflammatory mononuclear infiltrate in jejunal tubes and only slight infiltrate around the gastrostomy stoma. In the CG, ulceration was constant around the external stoma of the gastrostomy tubes. In the corium, the inflammatory infiltrate was less intense than in the SG. The SG proved to be more efficacious than the CG concerning leakage, and this efficacy is attributed to the submucous valvular system. CONCLUSION: The featured technique showed competence concerning leakage, allowing its clinical applicability as an alternative for permanent gastrostomy.

OBJECTIVE: To establish if previous surgery for benign prostatic hyperplasia (transurethral resection of the prostate or open prostatectomy), age, and preservation of prostatic apex can influence postoperative urinary continence in patients submitted to radical cystectomy and orthotopic ileal neobladder. PATIENTS AND METHODS: We analyzed 62 patients with bladder cancer who were treated with radical cystectomy and orthotopic ileal neobladder between 1987 and 1998 and had been followed for at least 24 months. The average age and median follow up were 61 years and 53 months, respectively. Postoperative urinary continence was correlated with 3 factors: patient age, preservation of prostatic apex during surgical excision and prior prostatic surgery for benign disease. Patients were defined as incontinent when they had to use more than 1 protective pad at the daytime. RESULTS: The overall incidence of urinary incontinence was 12.9% (8 out of 62 patients). The only statistically significant factor that impacted upon urinary continence was previous prostatic surgery, with respectively 33% versus 7% rate of incontinence for patients previously operated on and for those without previous operation (p = 0.023 odds ratio = 6.5, 95% confidence interval). Preservation of prostatic apex did not reach difference, 12% versus 13%, for those with and without preservation, and age also did not influence the postoperative continence rate. CONCLUSIONS: Prior prostatic surgery for benign prostatic hyperplasia probably can increases the risk for postcystectomy incontinence and preservation of prostate apex did not affect the continence rate. This issue deserves to be considered by the surgeon and must be discussed previously with the patients when planning an orthotopic bladder replacement.

OBJECTIVE: To describe the original cystoprostatectomy technique which allows the preservation of sexual and urinary function in the majority of treated patients. SURGICAL TECHNIQUE: The described technique presents some details that distinguish it from classic cystectomy: 1) a more efficient control of prostate venous and arterial tributaries; 2) preservation of prostatic capsule and enucleation of prostatic parenchyma, which is removed in block together with the bladder, without violating the vesical neck; 3) no manipulation of the distal urethral sphincteric complex; 4) preservation of seminal vesicles and maintenance of cavernous neurovascular bundles; 5) wide anastomosis between the ileal neobladder and the prostatic capsule. COMMENTS: The proposed maneuvers allow the performance of radical cystectomy with integral preservation of distal urethral sphincter and of cavernous neurovascular bundles, without jeopardizing the oncological principles.

The article presents a case study of a 38-year-old woman who was diagnosed with multiple bladder stones and examined using mitrofanoff cystolitholapaxy. Topics discussed include the use of mitrofanoff cystolitholapaxy in stone clearance in hostile abdomen with inaccessible urethra, the method's postoperative complications, its diverse effects, and urinary reservoirs.

The objective was to assess urine collection methods through cotton in contact with genitalia and urinary collector to measure urinary density in newborns. This is a quantitative intervention study carried out in a neonatal unit of Fortaleza-CE, Brazil, in 2010. The sample consisted of 61 newborns randomly chosen to compose the study group. Most neonates were full term (31/50.8%) males (33/54%). Data on urinary density measurement through the methods of cotton and collector presented statistically significant differences (p

Purpose: The aim of this study was to investigate the long-term clinical effects of sigmoidrectal pouch for urinary diversion. Materials and Methods: A total of 45 patients, including 40 males and 5 females, underwent sigmoid-rectal pouch procedure. The patients aged from 38 to 70 years with a mean age of 59 years. The postoperative follow-up ranged from 6 months to 19 years with an average of 6 years. Postoperative continence and voiding were analyzed, urinary reservoir pressure was measured and the complications of upper urinary tract were determined. The index of quality of life (QoL) in the International Prostate Symptom Score (IPSS) was used to evaluate the degree of satisfaction to urinate. Results: Forty patients had slight incontinence in the early postoperative stage and could control urination well 30 days postoperatively. The volume of pouch was 270-600 mL with an average of 375 mL. The basic pressure during filling period was 6-20 cmH2O with an average 15 cmH2O, the maximum filling pressure was 15-30 cmH2O with an average 26 cmH2O. The compliance of sigmoid-rectal pouch was fine with an average of 30 (range 18-40) mL/ cmH2O. There were no severe complications such as hyperchloremic acidosis or retrograde pyelonephritis. Six patients had slight hydronephrosis. The index of QoL were 0-2 in 20 patients, 3 in five patients and 4 in two patients. Conclusion: The sigmoid-rectal pouch operation was simple and acceptable by surgeons and patients. It may be an ideal urinary diversion for patients with muscle-invasive bladder cancer, especially for patients on whom urethrectomy should be done. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To evaluate in a rabbit experimental model a mechanism of continence of catheterizable urinary conduits (CUC), focusing on the behavior of intersected rectal muscle fibers in relation to the channel by histological and histochemical analysis, and secondarily to register conduit continence rates from clinical and urodynamic data. Materials and methods: 12 rabbits were submitted to construction of a CUC from two abdominal skin flaps and divided into two groups: 8 with a urinary neo-sphincter created according to Yachia and 4 controls. We registered clinical outcome, urodynamic studies and microscopic analysis of CUC on the surface of the conduit, which was in direct contact with the mechanism of continence. We took muscle samples from the mechanisms of continence and performed histochemical evaluation by enzymatic reactions. Results: Histological evaluation of the CUC showed no difference between groups. Histology and immunohistochemistry of the muscle fibers showed that areas of necrosis, cell atrophy and motor neuron injury from the first eight weeks recovered by the end of 16th week. Conduit complications occurred in 4 animals (33%). The average detrusor leakage point pressure through the conduit was 90 cm H2O versus 39 cm H2O through the urethra. Conclusion: The mechanism of continence did not promote ischemic stress on the conduit, was able to promote high pressure resistance and showed good recovery of intersected muscle fibers, after an initial slight atrophy, suggesting good durability of the neo-sphincter.

Purpose: Bladder neck closure is an irreversible procedure requiring compliance with catheterization of a cutaneous stoma and historically has been reserved for the definitive treatment of intractable incontinence after prior failed procedures. We assessed long-term outcomes of our patients undergoing bladder neck closure including continence status, additional surgical interventions, postoperative complications, conception and sexual function, and satisfaction with bladder neck closure. Materials and Methods: We performed a retrospective review of all patients who underwent bladder neck closure between 1990 and 2010 at our institution. Results: A total of 28 consecutive patients (exstrophy 15 and neurogenic bladder 13 [myelomeningocele 4, cloacal anomaly 4, spinal cord injury 2, VACTERL (Vertebral Anorectal Cardiac Tracheo-Esophageal Radial Renal Limb) 1, sacral agenesis 1 and urogenital sinus 1]) were identified. Of these patients 19 (68%) had undergone 20 unsuccessful bladder neck procedures before bladder neck closure. Bladder neck closure was initially successful in 27 of the 28 (96.4%) patients. One patient required subsequent closure of a postoperative vesicovaginal fistula. Median time from bladder neck closure was 69 months (range 16 to 250). In 11 patients 16 additional procedures were required, including stomal injection of bulking agents (2), stomal revision for stenosis (2) or prolapse (1), percutaneous nephrolithotripsy for stone (1), open cystolithotomy (2), extracorporeal shock wave lithotripsy for upper tract stones (4), repair of augment rupture (3) and open retrograde ureteral stenting for stone (1). The total surgical re-intervention rate was 39.3% (11 of 28). There were no observed cases of progressive or de novo hydronephrosis. Conclusions: Bladder neck closure in conjunction with enterocystoplasty and Mitrofanoff diversion is an effective means of achieving continence in complex cases as a primary or secondary therapy. Long-term urological followup into adulthood is essential. [Copyright &y& Elsevier]

Augmentation cystoplasty and urinary diversion are no longer commonplace in the management of patients with neurogenic bladder, but remain an important surgical treatment for those with refractory LUTS who have failed neuromodulation and onabotulinum toxin treatment or who are not candidates for those treatments. Augmentation is an option in patients who can perform intermittent catheterization and is usually performed with ileum or large intestine. Some patients benefit from continent cutaneous catherizable channels. Supravesical urinary diversion may be necessary in more severe cases. Ileovesicostomies are being supplanted by indwelling suprapubic catheters, and when catheters fail conduits may be a better option. When feasible, the diverted bladder should be excised to avoid pyocystis. [ABSTRACT FROM AUTHOR]

Purpose: Urothelium lined seromuscular colocystoplasty is an ideal method of augmentation cystoplasty that avoids various complications caused by the use of gastrointestinal segments. We reviewed the long-term outcomes using this technique at a single institution. Materials and Methods: We retrospectively analyzed 34 patients who underwent urothelium lined seromuscular colocystoplasty between January 1996 and December 2007. A total of 33 patients, excluding 1 who had previously undergone artificial urinary sphincter implantation, were included in the study. Changes in urodynamic parameters, duration of anticholinergic use, incontinence and surgical complications were analyzed. Results: Mean ± SD age at surgery was 10.0 ± 5.7 years (range 3.0 to 26.0) and duration of followup was 6.0 ± 2.3 years (2.7 to 13.4). A total of 17 patients (51.5%) underwent simultaneous anti-incontinence surgery and urothelium lined seromuscular colocystoplasty. Mean bladder capacity increased by a factor of 2.96 and mean percentage of expected bladder capacity for age increased by a factor of 1.96 postoperatively. Of patients who underwent anti-incontinence surgery 4 of 10 whose abdominal leak point pressure was less than 40 cm H2O required additional surgery, whereas none whose abdominal leak point pressure was 40 to 60 cm H2O required reoperation. Two of 16 patients who did not undergo anti-incontinence surgery eventually required continence surgery. A total of 13 patients (39.4%) were able to discontinue anticholinergics at 47.3 months postoperatively. There were no bladder perforations, bowel obstructions or metabolic abnormalities. Conclusions: Urothelium lined seromuscular colocystoplasty can be primarily considered in patients without prior bladder mucosal injury. Constant high bladder outlet pressure to facilitate adhesion of bladder mucosa and seromuscular patch is critical for the best results. We recommend abdominal leak point pressure 60 cm H2O or less as an indication for simultaneous anti-incontinence surgery and urothelium lined seromuscular colocystoplasty. [ABSTRACT FROM AUTHOR]

Purpose: This animal study was designed to investigate whether the composite urinary reservoir might lessen the premalignant histological alterations observed after bladder augmentation performed with a gastric segment or large bowel. Materials and Methods: Composite urinary reservoirs were created using gastric and colonic segments simultaneously in 8, 3-month-old female beagle dogs by augmenting half the native bladder. Two dogs with gastrocystoplasty and 2 with colocystoplasty served as controls. Biopsies were taken from the native bladder, and the gastric and colonic segments at augmentation, and endoscopically 4 and 8 months postoperatively. The dogs were sacrificed and open biopsied 12 months postoperatively. Tissue specimens were examined with routine hematoxylin and eosin, reaction and immunohistological staining for PCNA. Results: At the creation of composite reservoir and gastrocoloplasty or colocystoplasty all specimens showed normal histology. At 12 months postoperatively dysplasia was found in 1 gastric segment, 2 native bladders and 3 colonic segments in the composite reservoir group. There was a single carcinoma in situ in 1 gastric segment in the composite reservoir group. In the control groups 1 colonic segment and 1 native bladder dysplasia were detected at the end of 12-month followup. There was an in situ carcinoma in 1 gastric segment in the composite reservoir. Conclusions: A composite reservoir did not decrease premalignant changes in dogs during 12 months of followup. Laboratory investigations, molecular studies and longer followup are needed to approach the question of early malignant alterations after augmentation cystoplasty in animals and patients.

Abstract: Objectives and methods: Vulvar carcinomas are rare genital malignancies. While advanced primary cancer chemoradiation is often preferred over pelvic exenteration (PE), PE is often the only therapy available in cases of recurrence. In a retrospective study, we analyzed predictive factors and outcomes of patients who underwent exenteration for vulvar cancer in our department during the past 10years. Results: We identified 27 patients; 9 of them suffered from primary disease, and 18 had experienced a recurrence. A total of 18 patients presented with stage FIGO III, and 9 patients presented with stage IV. In 10 patients, the disease had spread to the inguinal lymph nodes, and in 3 patients, it had also spread to the pelvic nodes. At the end of surgery, all patients were macroscopically tumor free, which was confirmed microscopically in 20 patients (74%, R0), with the other 7 patients having microscopic tumor remnants. For all patients, median time of survival was 37months, the five-year survival rate (5YSR) was 62%, and the overall survival (OS) was 59%. Patients with tumor-free lymph nodes had an OS of 76% and a 5YSR of 83% vs. 40% and 36%, respectively, for patients with tumorous spread to the nodes (p =0.03). The 5YSR correlated to the degree of resection (R0 vs. R1, 74% vs. 21%, p =0.01). Conclusion: PE is a therapeutic option in advanced primary or relapsed vulvar carcinoma, offering median- to long-term survival for many patients. Carcinomatous spread to regional lymph nodes and complete resection are the most important prognostic factors. [Copyright &y& Elsevier]

Purpose: Children with end-stage renal disease and bladder dysfunction may require augmentation cystoplasty before kidney transplantation. Previous reports have suggested unacceptable urinary tract infection rates in these immunosuppressed patients. We reviewed our experience in this population. Materials and Methods: We retrospectively studied patients undergoing augmentation cystoplasty and subsequent renal transplantation by a single surgeon between 1989 and 2007. This cohort was compared with a control group on clean intermittent catheterization who had undergone transplantation without augmentation. Patient demographics, etiology of renal failure, surgical details, surgical/allograft outcomes and occurrence of urinary tract infection were analyzed. Results: The augmented group included 17 patients with a median age at reconstruction of 6.4 years. Stomach was used in 15 patients and colon in 2. Median time between reconstruction and transplantation was 1.2 years. Median followup after transplantation was 7.7 years. The control group included 17 patients with a median age at transplantation of 10.9 years. Median followup in the controls was 6.1 years. All ureteral reimplantations were antirefluxing. Patients on clean intermittent catheterization were maintained on oral antibiotic suppression and/or gentamicin bladder irrigations. In the augmented group 35 episodes of urinary tract infection were noted, and the number of documented infections per patient-year of followup was 0.22, compared to 32 episodes of urinary tract infection and 0.28 infections per patient-year of followup in the controls. No allograft was lost to infectious complications. Conclusions: In our series there was no increase in urinary tract infection rate following renal transplantation in patients with augmented bladders compared to controls. This finding may be due to the use of gastric augmentation, antirefluxing reimplantation and gentamicin irrigations. [Copyright &y& Elsevier]

Purpose: Continent catheterizable channels for emptying the bladder are typically performed via an open surgical approach. We present our surgical approach and initial outcomes with specific attention to continence for robotic assisted laparoscopic Mitrofanoff appendicovesicostomy formation. Materials and Methods: Between February 2008 and April 2010, 13 patients were considered for robotic assisted laparoscopic Mitrofanoff appendicovesicostomy and 11 underwent the procedure (2 open conversions). Five patients underwent enterocystoplasty with appendicovesicostomy and 6 underwent isolated appendicovesicostomy. The appendicovesicostomy anastomosis was performed on the anterior (without augmentation) or posterior (with augmentation) bladder wall and the stoma was brought to the umbilical site or right lower quadrant. Detrusor backing (4 cm) was ensured except in 1 patient (number 5). Results: Mean patient age at surgery was 10.4 years (range 5 to 14). Mean estimated blood loss was 61.8 cc. Mean operative time for isolated appendicovesicostomy was 347 minutes and there were no intraoperative complications. Incontinence through the stoma developed in 1 patient with inadequate detrusor backing (less than 4 cm), which resolved with dextranomer/hyaluronic acid injection into the appendicovesicostomy anastomosis. This patient had resolution of incontinence with an increase in bladder capacity to 300 cc. Three patients required skin flap revision for cutaneous scarring. To date all patients are catheterizing without difficulty and are continent. Median followup was 20 months (range 3 to 29). Conclusions: We are encouraged by our preliminary experience with the robotic assisted laparoscopic Mitrofanoff appendicovesicostomy continent urinary diversion with or without ileocystoplasty. Early in the experience we emphasize the importance of 4 cm of detrusor backing to maintain stomal continence. [ABSTRACT FROM AUTHOR]

Creating a continent urinary pouch has become an alternative to the ileal conduit for patients undergoing exenteration for advanced gynecologic malignancies. The objective of this study was to compare clinical outcomes for the 2 methods.In this retrospective study, we compared intraoperative and postoperative complications and quality-of-life scores for the modified ileocecal pouch and the ileal conduit in anterior or total pelvic exenteration.In 33 of 100 patients, an ileal pouch (IP) was created; the other 67 were treated by an ileal conduit (IC). Creating an IP prolonged the exenterative procedure by 97 minutes compared to an IC (IC, 453 minutes vs IP, 550 minutes; P = 0.009). Overall complication rates were similar, but patients with an IP had significantly more complications of urinary diversion (48%) than patients with an IC (31%; P = 0.03). Follow-up showed urinary loss and frequency of micturition to be comparable, but in patients with an IP, surgery for stomal complications (n = 2) and treatment of bladderstones were necessary more frequently (n = 3). Quality of life according to the 12-item Short Form Health Survey questionnaire was similar in both groups.A continent IP is an alternative to the IC in cases of pelvic exenteration. Early complications are more frequent with an IP than with an IC. The mode of urinary diversion has little influence on the quality of life in patients with advanced genital cancer.

Purpose: We provide the long-term results of renal transplantation into continent urinary intestinal reservoirs as a planned 2-stage procedure. Materials and Methods: Between November 1990 and January 2009, 18 patients underwent cadaveric or living related renal transplantation into continent urinary reservoirs (continent cutaneous diversion 16, orthotopic substitution 2). All patients were prospectively followed. Results: Of these patients 15 are currently free of dialysis. At a mean followup of 89.2 months (range 2 to 188) 13 patients had a serum creatinine ranging from 0.6 to 3.1 mg/dl (mean 1.49) after the first transplantation. Two patients underwent a second transplantation 12 and 122 months after loss of the transplant for renal vein thrombosis and chronic allograft dysfunction, respectively. Two additional patients had to resume hemodialysis 62 and 109 months after renal transplantation. The second transplantation was delayed mainly due to compliance problems. One patient died of fulminant septicemia after laparotomy elsewhere for bowel obstruction with normal renal function before that episode. The continence mechanism needed correction in 3 patients, and 2 further revisions were required for ureteral kinking and lymphocele. The patients with orthotopic substitution (2) voided to completion and showed complete continence. All patients with cutaneous diversion were continent day and night with easy catheterization. Conclusions: This study is among the largest single series to date of renal transplantation into continent urinary diversions. Long-term followup confirms that this approach is a safe and socially well accepted treatment option in carefully selected patients. [ABSTRACT FROM AUTHOR]

Abstract: Background: The need for and intensity of follow-up to detect disease recurrence after radical cystectomy (RC) for transitional cell carcinoma (TCC) remains a matter for debate. Objective: To determine whether diagnosis of asymptomatic recurrence after RC by routine follow-up investigations confers a survival benefit versus symptomatic recurrence. Design, setting, and participants: Retrospective analysis of 479 patients with nonmetastatic bladder TCC receiving no neoadjuvant chemotherapy/radiation therapy and prospectively followed with a standardised protocol for a median 4.3 yr (range: 0.3–20.9) after RC at an academic tertiary referral centre. Intervention: RC and extended pelvic lymph node dissection with ileal orthotopic bladder substitution. Measurements: Cancer-specific survival (CSS) and overall survival (OS) probability for asymptomatic and symptomatic recurrent patients were estimated using the Kaplan-Meier method. The effects of age, nerve-sparing surgery, pathologic tumour stage, lymph node status, adjuvant chemotherapy, mode of recurrence diagnosis, and recurrence site on survival were assessed with multivariable Cox regression models. Results and limitations: Of the 174 of 479 patients (36.3%) with tumour recurrence, 87 were diagnosed by routine follow-up investigations and 87 by symptoms. Routine follow-up mostly detected lung metastases and urethral recurrences, while symptoms were predominantly the result of bone metastases and concomitant pelvic/distant recurrences. Of 24 patients with urethral recurrences, 13 had carcinoma in situ (CIS). Of these, 12 were successfully managed with urethra-sparing treatment, and 6 are still alive with no evidence of disease. Most other recurrent long-term survivors had lung and extrapelvic lymph node metastases. Cumulative 5-yr survival rates of the entire cohort were 69.8% (95% confidence interval [CI], 65.5–74.3%) for CSS and 61.9% (95% CI, 57.4–66.7%) for OS. In multivariable analysis, mode of recurrence diagnosis and site of initial recurrence were the only independent predictors of CSS and OS. Patients with recurrences detected by routine follow-up investigations and with secondary urothelial tumours as site of recurrence had a slightly but significantly higher survival probability. Conclusions: Patients diagnosed with asymptomatic recurrences during our routine follow-up after RC had a slightly higher survival than patients with symptomatic recurrences. Routine follow-up appears particularly effective in early detection of urethral CIS, which can be treated conservatively. In addition, the predominance of lung and extrapelvic lymph node metastases in survivors may justify the use of routine cross-sectional imaging. [Copyright &y& Elsevier]

Study Type – Therapy (case series) Level of Evidence 4 OBJECTIVE To evaluate our experience with urethral recurrences in patients treated by radical cystectomy(RC) and orthotopic neobladder urinary diversion for carcinoma of the bladder. PATIENTS AND METHODS We retrospectively reviewed the records of patients treated with RC and orthotopic urinary diversion between January 1980 and July 2004. RESULTS In all, 260 patients underwent RC with a Studer or Hautmann orthotopic urinary diversion; the median (range) follow-up was 5.1 (0–15.6) years. Six patients (2.3%) developed local recurrence of urothelial cancer (UC) within the urethra after this treatment. The median (range) time to presentation with recurrence after RC was 2.4 (0.7–3.6) years for pT1-4 UC. Recurrences were treated with various methods, including transurethral resection, urethrectomy with conversion of neobladder to continent catheterizable diversion, and chemotherapy. At the last follow-up, four of these six patients were alive without disease, one was alive with disease, and one had died from disease. CONCLUSIONS In our experience, local recurrences involving the urethra are infrequent. Complete surgical excision can provide a good outcome. Neoadjuvant chemotherapy should be considered for recurrences with adverse clinicopathological features. [ABSTRACT FROM AUTHOR]

Purpose: We present the long-term results of simultaneous “teapot” ureterocystoplasty and ureteral Mitrofanoff in patients with bilateral megaureters due to neurogenic bladder, and compare urodynamic results before and after the procedure. Materials and Methods: We treated 13 children (mean age 7.3 years) with end stage neurogenic bladder and refluxing megaureters (mean diameter 5.5 cm) with simultaneous teapot ureterocystoplasty and Mitrofanoff appendicovesicostomy between April 1995 and May 2001. The larger ureter was used for teapot bladder augmentation while keeping its distal 2 cm tubularized. The Mitrofanoff channel was then created using the opposite ureter. Results: Followup ranged from 109 to 169 months (median 121). At the end of the followup period all patients were dry with clean intermittent catheterization and/or voiding. No repeat augmentation was needed and there were no bladder calculi during followup. Median postoperative bladder capacity was 430 ml (IQR 380 to 477), which was increased significantly compared to preoperative evaluations (210 ml, IQR 181 to 230, p = 0.001). During followup bladder compliance also improved significantly (p = 0.001) and serum creatinine level decreased (p = 0.021). Conclusions: Although neurogenic bladder and high grade reflux are poor prognostic factors for ureterocystoplasty, the present modification resulted in enduring bladder augmentation with no calculus formation. Bladders remained compliant with good capacity, presumably because sufficient tissue and blood supply were provided for the augmented flap. [Copyright &y& Elsevier]

Purpose: Extant literature is mixed regarding risk of metabolic acidosis after enteroplasty for myelomeningocele. This study is the first known attempt to describe the pattern of developing metabolic acidosis in a group of children who underwent enteroplasty and served as their own controls. Multiple preoperative and postoperative laboratory measures for each child were obtained for comparison. Materials and Methods: This retrospective cohort study allowed participants to serve as their own controls for pre-intervention and post-intervention analysis. The setting was a tertiary, university affiliated, interdisciplinary spina bifida program. All patients followed in the spina bifida program who had undergone ileal or colonic enteroplasty were included for review (total 113). Strict exclusion criteria were preoperatively diagnosed renal insufficiency, preexisting metabolic acidosis consistent with renal tubular acidosis (pH less than 7.35, bicarbonate 20 mmol/l or less) and history of augmentation using gastric or ureteral tissue. Final analysis included 71 children who met inclusion criteria. Children in our spina bifida program periodically undergo routine laboratory evaluation of electrolytes, blood urea nitrogen, creatinine, blood count, and venous blood gases including pH, bicarbonate and partial pressure of carbon dioxide. Primary outcome measures were comparative shifts in blood gases and electrolytes that would confirm the new onset of metabolic acidosis after enteroplasty. Changes in electrolytes and serum creatinine were secondary outcome measures to identify potential markers for postoperative effects. With each child as his/her own control, analysis included paired t tests. Results: No statistically significant differences (p <0.05) were found when comparing laboratory values before and after bladder augmentation, including pH, bicarbonate, partial pressure of carbon dioxide and electrolytes. No child had metabolic acidosis based on the aforementioned criteria. Followup ranged from 1 to 138 months after enteroplasty (mean 46.8). Respiratory compensation was considered in the analysis, and no difference in partial pressure of carbon dioxide following surgery was noted (p = 0.65). Conclusions: To our knowledge no previous study has examined the matched paired results of before and after development of metabolic acidosis among children (serving as their own controls) with myelomeningocele undergoing ileal or colonic enteroplasty. The negative statistical results in this controlled cohort are clinically significant. If a child with myelomeningocele has metabolic acidosis after enteroplasty, other clinical reasons beyond the effects of surgery warrant careful consideration. [Copyright &y& Elsevier]

Introduction: We report a new modified technique of unaltered appendix transfer to ileal pouch and preserving ileocecal segment. This modification enables us to use ileum as the popular type of enteric segment instead of ileocecal segment while using appendix as a catheterizable stoma. Materials and Methods: Forty-five patients (30 men) who needed reconstruction of the lower urinary tract were enrolled for using appendix as a catheterizable stoma. Reservoir was reconstructed using ileal segment. The appendix was circumcised from its base over its pedicle. The spatulated appendix tip was exteriorized as a catheterizable stoma to the skin, preferably umbilicus, and its base was implanted to the ileal pouch. Results: Follow-up records of 38 of 45 patients were available. The median follow-up period was 29 months. The mean intermittent catheterization interval was 4.19 ± 1.6 hours. Urodynamic parameters were evaluated for 18 out of 38 patients. The median maximal pouch capacity determined as 380 mL. The median appendiceal closure pressure was 61 cm H2O. No pouch perforation occurred. Stomal stenosis occurred in 3 patients. They did not catheterize their appendiceal stoma because they restarted catheterization through the urethra. Conclusion: This novel approach enabled us to use ileum as today's more popular type of bowel segment to reconstruct enteric pouch rather than using ileocecal segment, while using appendix as a catheterizable stoma. One of the unique advantages of this technique is that the postponement of clean intermittent catheterization will not result in pouch perforation since the urine will leak when the pouch become overfill.

Purpose: In rare instances when native bladder tissue is either unsuitable or unavailable a continent neobladder may be an option for pediatric lower urinary tract reconstruction. We report our long-term outcomes and experience in this challenging patient population. Materials and Methods: A retrospective cohort study was performed of all patients who underwent creation of a neobladder at 2 pediatric institutions. Patient demographics, surgical details and clinical outcomes were abstracted from the medical records. Results: A total of 26 patients were identified with a median age of 8.9 years at surgery. Median followup was 8.0 years. Most procedures used a composite of gastric and ileal tissue. All patients were continent of urine and had a stable upper urinary tract. Median bladder capacity was 400 ml. Postoperative complications included reservoir stones (8 patients), febrile urinary tract infection (8), metabolic acidosis (6), small bowel obstruction (4), bladder perforation (4) and pelvic lymphocele (1). Five patients had difficulty with catheterization due to stomal stenosis. Gross hematuria with clots developed in 1 patient with anuria who had a gastroileal neobladder and was awaiting renal transplantation. No other patient with a gastric component had the hematuria-dysuria syndrome. Five patients had end stage renal disease and subsequently underwent successful renal transplantation. No upper urinary tract deterioration was observed, and no malignant transformation has occurred. Conclusions: Creation of a continent neobladder is a reconstruction option in children when bladder augmentation is not feasible. However, complication rates are not insignificant, underscoring the need for careful long-term followup. [Copyright &y& Elsevier]

Purpose: Many institutions have reported varied levels of success with ureterocystoplasty. Recently, there have been concerns regarding the efficacy of ureterocystoplasty as a form of bladder augmentation. We report our long-term functional outcomes with the procedure based on the experience of a single surgeon. Materials and Methods: A total of 17 procedures were performed during a 12-year period. Of the patients 10 had posterior urethral valves, 3 had bladder exstrophy, 2 had a neuropathic bladder, 1 had a cloacal anomaly and 1 had a left ectopic ureter. Mean patient age at operation was 5.9 years (range 0.3 to 14.2). All patients underwent preoperative ultrasound, urodynamic studies and radionuclide scanning. Postoperative urodynamics were performed at 6 months. Results: Followup ranged from 0.5 to 11.5 years (mean 4.5). Nine patients underwent ureterocystoplasty with preservation of the ipsilateral kidney, and 1 underwent ureterocystoplasty alone and had a solitary right kidney. The remaining 7 patients underwent ureterocystoplasty with ipsilateral nephrectomy. Postoperatively, the mean bladder capacity improved from 125 to 292 ml, while the mean end filling pressure decreased from 72 to 22 cm H2O. Mean preoperative system compliance was 2.1 ml/cm H2O, which increased to 16.2 ml/cm H2O postoperatively. A total of 13 patients did not require further augmentation surgery. The remaining 4 patients had high pressure and poorly compliant bladders, and underwent ileocystoplasty. Subsequent postoperative nucleotide scans in these 4 patients demonstrated stable upper tracts with good drainage. Conclusions: Based on our results, ureterocystoplasty provides durable functional urodynamic improvement in patients with a megaureter. [Copyright &y& Elsevier]

Purpose: Augmentation gastrocystoplasty has been proposed as an alternative to enterocystoplasty because of potential benefits, including decreased risk of mucus production, stone formation and urinary tract infections. Although cancer has rarely been reported in this patient population, it is a well recognized potential risk of all augmentation cystoplasties. To define better the risk of malignancy associated with gastric augmentation and the appropriate surveillance protocol for these patients, we describe our experience in 2 patients with metastatic adenocarcinoma following gastrocystoplasty. Materials and Methods: We retrospectively reviewed the charts of all patients who had undergone augmentation gastrocystoplasty between 1990 and 1994. Of the 72 patients identified 2 were diagnosed with a primary malignancy arising from the augmented bladder. Charts were reviewed for medical history, clinical outcomes and pathology. Results: Two patients were identified with a primary bladder malignancy after gastrocystoplasty. Both patients had metastatic disease at initial presentation. Neither patient had a history of gross hematuria, recurrent urinary tract infections or pain before initial presentation. Mean patient age at augmentation was 5.5 years. Mean age at diagnosis of malignancy was 19.5 years, with a mean time from augmentation of 14 years. Conclusions: Although the risk of bladder cancer is low after gastric augmentation, the effects may be life threatening. Therefore, we advocate routine annual surveillance with cystoscopy, bladder biopsy and upper tract imaging in all patients who have undergone augmentation gastrocystoplasty. [Copyright &y& Elsevier]

Purpose: A skin lined Mitrofanoff stoma in the iliac fossa is traditionally achieved using a VQZ technique, providing a channel for intermittent catheterization. We simplified our approach by using a VQ flap at the distal end of the Pfannenstiel incision. We present a comparison of the functional and cosmetic outcome of these 2 approaches. Materials and Methods: Records of all patients requiring a Mitrofanoff stoma performed by a single surgeon (RS) were reviewed. Data were collected from hospital notes, patient followup clinics and urology nurse specialist records. All VQ type stomas were performed since March 2004. Results: A total of 21 patients had 23 stomas formed (11 VQZ and 12 VQ plasty). Each group was composed mainly of appendiceal conduits. Three ileal (Monti) conduits were formed. Mean followup was 18.3 months for VQZ and 15 months for VQ cases. Removing the Z flap leaves behind a neat skin lined stoma unlike a VQZ plasty, which results in a more prominent and irregular scar. One VQ stoma prolapsed slightly. Three stomas were revised in the VQZ group for stenosis (1 traumatic) or leakage, 2 using VQ plasty. Conclusions: Formation of a skin lined stoma by VQ plasty as opposed to VQZ plasty reduces scarring around the conduit without affecting the complication rate or stoma continence. Patients continue to be positive about the cosmetic appearance of the stoma. [Copyright &y& Elsevier]

Purpose: Complete continent urinary diversion not incorporating the bladder is not commonly used in children. We evaluated the short and long-term outcome of a form of continent cutaneous urinary diversion (Charleston pouch I) in children. Materials and Methods: A total of 17 children underwent Charleston pouch I continent cutaneous urinary diversion between 1988 and 2005. Patient records were reviewed for age, sex, indications for diversion, preoperative and postoperative laboratory and radiological studies, continence, patient and family acceptance, complications and long-term functional status. Results: Patient age ranged from 6 to 16 years. The main indication for diversion was bladder exstrophy in 8 patients (47%), neurogenic bladder in 6 (35%) and cloacal abnormalities in 3 (18%). Mean followup was 87.5 months. One patient was lost to followup. With moderate fluid intake the other patients were dry with a mean catheterizing time of 3.4 hours (range 2 to 6). Catheterization intervals were adjusted for individual patients. Generally, the patients became damp or leaked if they did not catheterize at recommended intervals. Continence was achieved at variable postoperative intervals, with some patients attaining continence soon after and others at 3 to 12 months before pouch maturation. Patients irrigated the pouch a mean of 4 times weekly (range 0 to 14). Three patients (18%) had bladder stones. Ultrasound and/or other upper tract studies revealed no deterioration of the upper urinary system. No patient experienced clinical pyelonephritis or acidosis. Family and patient acceptance was satisfactory. Conclusions: Continent cutaneous urinary diversion with Charleston pouch I was satisfactory in this group of children. It provided preservation of the upper urinary tract, and achieved acceptable continence rates while allowing leakage when catheterization was not performed at recommended intervals. In addition, patient and parent acceptance was good, and complication rates were acceptable. [Copyright &y& Elsevier]

Purpose: The aim of this study was to determine whether redo bladder neck reconstruction is effective in achieving continence after a failed bladder neck reconstruction procedure. Materials and Methods: We retrospectively reviewed the hospital records of patients with bladder exstrophy who had undergone redo bladder neck reconstruction. There were 30 patients in the study, including 20 boys and 10 girls. Mean patient age at redo bladder neck reconstruction was 9.3 years (range 3.2 to 15.5). The patients were divided into 3 groups on the basis of the preoperative pattern of incontinence—incomplete wetters, complete wetters and those on continuous suprapubic drainage. Of the patients 15 already had undergone bladder augmentation, 12 had undergone a Mitrofanoff procedure and 12 had been treated with bulking agents injected in the bladder neck in an attempt to achieve continence. Four patients had undergone more than 1 bladder neck procedure. The patients were investigated with a combination of noninvasive urodynamics, cystoscopy, cystogram and ultrasound. All patients underwent Mitchell’s modification of Young-Dees-Leadbetter bladder neck reconstruction. Additional procedures performed included augmentation cystoplasty and Mitrofanoff formation. Results: Mean followup was 6.9 years (range 1.2 to 15.5). Postoperatively 28 patients were using clean intermittent catheterization to empty the bladder (5 per urethra, 23 via Mitrofanoff). Two patients remained on continuous suprapubic catheter drainage. A total of 18 patients (60%) were dry postoperatively (80% of girls and 50% of boys). Among dry patients only 3 were performing clean intermittent catheterization per urethra and 15 via a Mitrofanoff channel. No patient was able to void per urethra without the need for clean intermittent catheterization. The 2 patients on continuous suprapubic catheter drainage continued to remain so. At night only 50% of the patients were dry (5 on free drainage, 4 on clean intermittent catheterization, 6 not on any drainage). Those patients who did not respond satisfactorily to redo bladder neck reconstruction underwent subsequent additional procedures, which included injection of bulking agents (3 patients), insertion of an artificial urinary sphincter (1), Mitrofanoff formation (2) and bladder augmentation plus Mitrofanoff channel (1). Postoperative complications included difficulty with clean intermittent catheterization (8 patients), perivesical leak (1), recurrent epididymo-orchitis (1), upper urinary tract dilatation (2) and incisional hernia (1). Bladder neck closure was being considered in 5 patients. Conclusions: In our experience redo bladder neck reconstruction cannot achieve continence with volitional voiding per urethra. Although redo bladder neck reconstruction can render a significant number of patients dry, it is only effective if performed in conjunction with augmentation. Failure of the initial bladder neck reconstruction may be a reflection of a bladder that is of inadequate capacity and/or compliance. Therefore, bladder augmentation should be considered in all patients requiring redo bladder neck reconstruction. Bladder neck closure may be a better alternative to redo bladder neck reconstruction.

Purpose: Some authors reported that adopting a nerve sparing technique during radical cystoprostatectomy improves the continence outcome of orthotopic diversion in patients with invasive bladder carcinoma. We urodynamically evaluated the effect of nerve sparing cystoprostatectomy on external urethral sphincteric function. Materials and Methods: A total of 30 consecutive male patients who underwent nerve sparing cystoprostatectomy and ileal neobladder (NS group) were compared to a control group of 30 patients who underwent a similar procedure but without nerve sparing (non-NS group). Continence status was thoroughly clinically evaluated in parallel to erectile function in both groups. The urethral sphincteric mechanism was evaluated with urethral pressure profilometry in different positions. Results: Better urethral pressure profile parameters were found in patients in the NS group. Significantly longer functional urethral length (34.8 mm) was detected in NS group than in the non-NS group (30.1 mm). Moreover, the maximum urethral pressure was higher in the NS group but not to a statistically significant level. In the NS group there were no statistically significant differences between potent and impotent subgroups regarding the continence rate or urethral pressure parameters. Conclusions: There is urodynamic evidence that the nerve sparing technique improved urethral sphincteric function and, consequently, the continence rate. The denervated, most proximal part of the urethra in non-NS cases with lack of contraction and, therefore, any pressure, is a possible explanation for the difference in UPP. [Copyright &y& Elsevier]

Authors from Egypt present the results of a comparative study of bladder reconstruction after radical cystectomy for bladder cancer. They compared an ileocaecal bladder with a neo-ileal bladder, and found no difference in continence between them, but found the ileocaecal bladder to be better for renal unit preservation, residual urine and the development of acidosis. OBJECTIVE To compare an ileocaecal orthotopic bladder, (which has been the standard procedure in Egypt for >30 years) with the ileal neobladder, as there is no ideal continent orthotopic bladder replacement for patients after cystectomy for bladder cancer. PATIENTS AND METHODS Between June 1999 and December 2001, 60 patients with invasive bladder cancer were randomized into two groups. Group A comprised 29 patients who had radical cystectomy and reconstruction with an ileal neobladder (median age 50 years, 27 men and two women) and group B included 31 who had an ileocaecal bladder substitution after radical cystectomy (median age 51 years, 28 men and three women). RESULTS The complication rate after surgery in group A was 17%, with two deaths, one from acute myocardial infarction and the other from haematemesis. In group B, the complication rate was 13%, with two deaths, one from a massive pulmonary embolism and the other from liver cell failure. Daytime continence was achieved in 93% of patients in group A and 90% in group B. The mean (sd) postvoid residual urine volume was larger in group A than group B, at 90 (72) vs 12 (20) mL. Acidosis and hyponatraemia were evident in the patients in group A but in none in group B ( P < 0.05). The pelvicalyceal systems were preserved in 85% of patients in group A and 93% in group B during the 2-year follow-up. The mean (sd) renal cortical thickness was less in group A than in group B, at 1.8 (0.5) and 1.9 (0.2) cm, respectively. Although the cystometric capacity was greater and the basal pressure less in group A than B, these were not reflected in the degree of diurnal and nocturnal continence or back pressure on the renal units. CONCLUSION Continence in both pouches was similar but the renal units were preserved better in the ileocaecal than in the ileal neobladder. Residual urine volume was greater in the ileal neobladder, with its potential complications of infection and stone formation, and acidosis was more evident. [ABSTRACT FROM AUTHOR]

Abstract: Objective:: The aim of this review is to outline specific surgical complications, metabolic consequences and quality of life (QOL) following urinary diversion in patients undergoing radical cystectomy. Methods:: Based on a comprehensive literature search (MEDLINE) the published knowledge on urinary diversion was examined regarding the research question with an emphasis on contemporary cystectomy series. Results:: Despite the fact, that urinary diversion is commonplace in these days and the existing literature is rather extensive, the vast majority of assumptions are based on low level evidence (retrospective, single-institutional case series with small sample sizes and short-term followup). There are few randomized trials in this field. Early and late surgical complications following radical cystectomy have decreased over the past three decades for both incontinent and continent diversion, but are still significant. While metabolic disturbances are common after continent forms of urinary diversion, the problems can be minimized in most cases. Most reports testify that QOL is high after cystectomy irrespective of type of urinary diversion although urinary and sexual problems are common. Conclusion:: Careful patient selection, strict adherence to proper surgical technique and appropriate life-long follow-up are of paramount importance in the successful management of patients undergoing radical cystectomy for bladder cancer.

Patients and their urologists are quite rightly concerned about the possibility of neoplastic change within intestinal segments transposed to the lower urinary tract. This fear arises from the occurrence of latent adenocarcinoma arising from the urocolic anastomosis in approximately 10% of patients who underwent ureterosigmoidostomy in childhood. The present text provides an update of previous reviews and details work published since 1990 on epidemiological, experimental and clinical studies. Consideration of the collected evidence confirms the increased risk of colonic neoplasia following mixing of the faecal and urinary stream by ureterosigmoidostomy or its more recent variants. In contrast, the occurrence of tumours within transposed intestinal segments appears more likely to be related to the underlying urinary tract disease for which the surgery was performed rather than exposure of the intestinal mucosa to urine. This conclusion is, however, based on low level evidence and, despite the reassuring findings, caution is advised until more robust data are available to provide a confident risk assessment.

The efficacy of a new continent outlet mechanism using a simple ileal valve in a continent cutaneous urinary diversion was evaluated. In eight mongrel dogs, a 50 cm distal ileal segment was isolated. The distal 41 cm of the isolated segment was opened along the antimesenteric border while the proximal 9 cm was not detubularized. The distal 6 cm part of the non-detubularized segment was tapered over a 30 F catheter and closed with continuous 3/0 polyglactin sutures. In order to create a valve, this 6 cm tapered ileal segment was wrapped anteriorly by the most distal part of the detubularized ileal segment. The remaining part of the detubularized ileal segment was folded into a U configuration. The posterior plate was completed by joining the limbs of the U with running absorbable sutures. Afterwards, the reservoir was closed by folding the ileal plate in half in the opposite direction to which it was opened. The intact proximal 3 cm part of the isolated ileal segment was brought out to the abdominal skin. A pouchogram of the reservoir and video-urodynamic studies were performed to evaluate the efficacy of the continent outlet 18–20 weeks after surgery. Video-urodynamic studies and pouchograms of the reservoirs revealed no leakage from the continent outlet in any dog. Reservoirs had a mean capacity of 413±51 ml (range 356–447 ml). When the reservoir was filled to maximum capacity, the average total reservoir pressure was 29±4.7 cm H2O (range 21–45). This procedure, using a single ileal segment for construction of the continent cutaneous urinary diversion, is simple and safe. The ileal valve mechanism serves as a reliable continent outlet system.

Objective To describe a modified form of detubularization using a perimesenteric incision of the ileal segment, which increases the capacity of the neobladder and reduces the length of the ileal segment required. Patients and methods From February 1993 to November 1999, ileocystoplasty was undertaken in 20 patients (mean age 8.4 years, range 4–16). Six had myelodysplasia, four had primary epispadias, five had bladder exstrophy, three had post-traumatic lesions and two had cloacal exstrophy. The patients were divided into two groups; in the first (eight patients, mean age 9.6 years, range 5–15) the ileal segment was opened along the antemesenteric border and in the second (12 patients, mean age 7.7 years, range 4–16) the ileal segment was opened adjacent to the mesentery, perimesenterically. Each segment was then folded and the perimesenteric edges sutured to form the pouch. Results The patients were assessed at 1 year after surgery; the neobladder capacity was evaluated as ((neobladder capacity - bladder capacity)/body weight), which shows the relative increase of bladder capacity after enterocystoplasty per unit of weight. There was a statistically significant increase in neobladder capacity in group 2 (perimesenteric transection; Kruskal–Wallis chi-square, P = 0.005; Mann–Whitney U-test, P = 0.006). Conclusion These results indicate that augmentation can be carried out by perimesenteric transection of the intestinal segment, which improves compliance and increases capacity of the neobladder.
