Abstract
Overactive bladder syndrome (OAB) is a common, chronic, complex, often under-reported and under-treated condition with a significant impact on quality of life. It poses a high burden on healthcare systems. Clam ileocystoplasty is an invasive procedure typically reserved for the treatment of severe refractory cases. Malignant transformation in the area of anastomosis remains a rare but real, life-threatening risk in the patient group and requires active life-long surveillance and follow-up. We report the case of a 51-year-old woman who presented with recurrent urinary tract infections and non-visible haematuria 30 years after clam ileocystoplasty for urge incontinence. Imaging revealed an anterior bladder tumour with hepatic metastases. On multiple occasions, she was unfit for any invasive surgical sampling options to obtain tissue samples to allow for treatment planning, and was provided with best supportive care. The disease rapidly progressed to death within 10 weeks of presentation. This case buttresses the need for informed consent regarding the risks, including malignant transformation several years after the procedure, and the necessity for lifelong follow-up and surveillance cystoscopy, with frequency tailored to individual patient risk assessment.

Abstract
The Genitourinary Pathology Society (GUPS) undertook a critical review of the recent advances in bladder neoplasia with a focus on issues relevant to the practicing surgical pathologist for the understanding and effective reporting of bladder cancer, emphasizing particularly on the newly accumulated evidence post-2016 World Health Organization (WHO) classification. The work is presented in 2 manuscripts. Here, in the first, we revisit the nomenclature and classification system used for grading flat and papillary urothelial lesions centering on clinical relevance, and on dilemmas related to application in routine reporting. As patients of noninvasive bladder cancer frequently undergo cystoscopy and biopsy in their typically prolonged clinical course and for surveillance of disease, we discuss morphologies presented in these scenarios which may not have readily applicable diagnostic terms in the WHO classification. The topic of inverted patterns in urothelial neoplasia, particularly when prominent or exclusive, and beyond inverted papilloma has not been addressed formally in the WHO classification. Herein we provide a through review and suggest guidelines for when and how to report such lesions. In promulgating these GUPS recommendations, we aim to provide clarity on the clinical application of these not so uncommon diagnostically challenging situations encountered in routine practice, while also importantly advocating consistent terminology which would inform future work.

Systematic review of bladder cancer outcomes in patients with spina bifida. J Pediatr Urol 2017; 13:456.e1-456.e9. [PMID: 28687411 DOI: 10.1016/j.jpurol.2017.05.006] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Accepted: 05/06/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND In patients with congenital bladder anomalies, bladder augmentation is used as a last resort to reduce intravesical pressure, but concerns about malignant transformation in augmented patients were first raised in the 1980s. The best evidence to date indicates that augmentation does not appear to increase the risk of bladder cancer in spina bifida patients. To date, oncologic outcomes from patients with spina bifida with and without augmentation have only been available in small case reports. OBJECTIVE To systematically evaluate factors in myelomeningocele patients with bladder cancer, including bladder augmentation, that contribute to overall survival (OS). STUDY DESIGN A systematic review using PubMed was conducted by cross referencing terms 'myelomeningocele,' 'cystoplasty,' 'bladder cancer' and respective synonyms according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Inclusion criteria were studies with patients with an underlying diagnosis of myelomeningocele and bladder cancer with data on age, stage, and mortality status. Studies were excluded for spinal cord injury, history of tuberculosis or schistosomiasis, or prior ureterosigmoidostomy. RESULTS Fifty-two patients were identified from 28 studies with a median age at bladder cancer diagnosis of 41 years (range 13-73); 37 (71%) presented with stage III or IV bladder cancer. Overall survival at 1 year and 2 years was 48.5% and 31.5%, respectively. Overall survival was different between those with and without augmentation (P = 0.009) by log-rank analysis. No between-group differences in OS were seen based on age, management with indwelling catheter, diversion with ileal conduit or being on a surveillance program. Only stage remained a significant predictor of OS on multivariate analysis (HR 2.011, 95% CI 1.063-3.804, P = 0.032). Secondary analysis was performed after removing patients with gastric augmentation (n = 8), and no difference in OS was seen between patients with (n = 8) and without augmentation (n = 36, P = 0.112). Of augmented patients, latency to development of bladder cancer was variable (Summary Figure). DISCUSSION Bladder cancer is a deadly diagnosis in patients with congenital bladder anomalies like spina bifida, and while overall prevalence of the two conditions occurring together is low, bladder cancer will go on to affect 2-4% of spina bifida patients. The present study examined overall survival, and further characterized outcomes in these patients. Presence of a bladder augment did not appear to worsen overall survival. CONCLUSIONS Patients with myelomeningocele who developed bladder cancer had aggressive disease. Augmentation did not worsen OS, based on cases reported in the literature. Risk of bladder cancer should be discussed with all myelomeningocele patients.

Abstract
Urothelial tumors are very rare in children (to date, only about 150 cases have been reported worlwide). Only 20% occur before the age of ten. The aim of this study is to specify the clinicopathologic features of urothelial tumor in young patients, which require a slightly different approach to treatment. On the basis of the WHO/ISUP (World Health Organisation/International Society of Urological Pathology) consensus classification report, these lesions are usually low-grade lesions, non invasive, and rarely recurrent. The sex ratio is three boys to one girl. These tumors are located preferentially in the low urinary tract, especially in the bladder. The main symptom is the macroscopic hematuria, which requires ultrasound examination in all cases. Cystoscopy is indicated in case of lesion of the bladder wall, or in case of persistent or recurrent hematuria, to obtain definitive diagnosis and biopsies. The tumors are mainly located on the posterior or lateral bladder wall above the trigone or near the ureteral orifices. Treatment is based on the transurethral resection of the lesion. The subsequent monitoring is sparsely codified, due to the exceptional occurrence of these tumors in the paediatric age group. These patients are likely to have better outcome than older patients, but it is due to the predominance of noninvasive papillary urothelial tumors. Tumor recurrences are not uncommon. In case of invasive, high-grade urothelial carcinomas, metastases or even lethal outcome may occur in rare cases.

Abstract
We report a 54-year-old woman with an adenocarcinoma of an ileal neobladder arising upon a background of ileal mucosal dysplasia. We believe that no case study or report has previously documented neobladder ileal mucosal dysplasia adjacent to an ileal neobladder adenocarcinoma. This observation supports the current hypothesis that ileal neobladders are dynamic environments for potential malignancy, and moreover, suggests a sequence of morphologic and molecular derangements similar to that seen in colorectal carcinoma. Those patients status post ileal neobladder are at risk for glandular dysplasia and malignancy and should be followed closely.

Abstract
A 70 year-old woman visited our hospital complaining of macrohematuria. She had undergone augmentation ileocystoplasty for tuberculous bladder atrophy 50 years previously. CT and cystoscopy showed tumor at the ileovesical anastomosis. She underwent a partial cystectomy. The pathological diagnosis was adenocarcinoma of the ileal segment. Recurrence was observed with rapid progression. The patient died 8 months after the operation. In Japanese literature, 43 cases of carcinoma arising in augumented bladder have been reported. Average period to the diagnosis of the cancer from the ileocystoplasty is 33 years. The period of our case was 50 years, the longest in 43 cases.

Abstract
Small-cell carcinoma of the urinary bladder is a rare and aggressive type of bladder cancer that has a poor prognosis. The incidence has been gradually increasing because of the aging population. Owing to its rarity there are no available treatment guidelines. Several retrospective studies and 1 prospective study have provided some insight into therapy for this disease. A multimodal approach that includes chemotherapy, local radiation therapy, and definitive surgery in resectable cases appears to be an optimal management approach.

Abstract
INTRODUCTION To review the incidence and risks of bladder cancer following gastrointestinal augmentations done for congenial anomalies in childhood. MATERIALS AND METHODS A literature search using PubMed and Ovid Medline search engines was performed. MeSH terms evaluated were; bladder augmentations, enterocystoplasty, gastrocystoplasty, spina bifida, spinal dysraphism, myelodysplasia, neural tube defects, posterior urethral valves and bladder exstrophy were cross referenced with the terms, bladder cancer and urinary bladder neoplasm. All patients who developed a bladder cancer following a bladder augmentation for a congenital anomaly were reviewed. RESULTS A total of 20 cases of bladder cancer following augmentations for congential anomalies, were identified, 9 arose following ileal cystoplasty, 3 following colocystolasty and 8 following gastrocystoplasty. The incidence of cancer developing per decade following surgery was 1.5% for ileal/colonic and 2.8% for gastric bladder augmentations. The majority of cancers developing within the augmented bladder are at advanced stages at the time of diagnosis (60%; 12/20 cases were ≥T3 at diagnosis). Several of the cases that developed occurred in patients exposed to known carcinogenic stimuli and/or arose in bladders with a known predisposition to carcinoma. CONCLUSION Patients augmented with ileal or colonic segment for a congenital bladder anomaly have a 7-8 fold and gastric augments a 14-15 fold increased risk for the development of bladder cancer over standard norms. Published data is however unable to determine if gastrointestinal bladder augmentation is an independent risk factor for cancer over the inherent risk of cancer arising from a congenitally abnormal bladder.

Abstract
Small cell carcinoma of the urinary bladder (SCCUB) is considered to be a tumor with a neuroendocrine phenotype characterised by aggressive behaviour and poor prognosis. Small cell carcinoma of the urinary bladder comprises 0.35 to 1% of all bladder cancers and is frequently observed in combination with other histological subtypes of carcinoma. Clinical presentation is characterized by advanced stage at diagnosis and rapidly progressive disease. In daily clinical practice there is no gold standard for the management of patients affected by this disease. Treatment of patients with limited disease combines neoadjuvant platinum-based chemotherapy followed by specific local treatment of the primary tumour. Cystectomy or radiotherapy should be proposed on an individual basis. In the metastatic setting, prognosis remains poor with a potential benefit from chemotherapy containing platinum compounds. Treatment of small cell carcinoma of the urinary bladder is based on evidence obtained from case reports and retrospective analyses. Due to low disease frequency there is a lack of randomized trials to provide guidance as to optimal therapy. Thus, systemic and local approaches are extrapolated from the literature available for the treatment of small cell carcinomas at other (non-urological) sites. We provide an overview of the currently available literature with it's main focus on the treatment of either locally advanced or metastatic small cell carcinoma of the urinary bladder.

Abstract
OBJECTIVE To determine the risk of bladder cancer following enteric bladder augmentation. MATERIALS AND METHODS Patients followed for care after an enteric bladder augmentation have been entered into a registry; individuals followed for a minimum of 10 years were evaluated. RESULTS The study criteria were met by 153 patients. Indications for bladder augmentation were neurogenic bladder in 97, exstrophy in 38 and posterior urethral valves in 18. There was a median follow-up interval of 27 years (range 10-53). A total of seven cases of malignancy developed. Median time to tumor development following augmentation was 32 years (range 22-52). Two patients with neurogenic bladder developed transitional cell carcinoma; both were heavy smokers (>50 pack per year history). Two patients with a history of posterior urethral valves and renal transplantation developed adenocarcinoma of the enteric augment. Three patients with bladder exstrophy developed multifocal adenocarcinoma of the augmented bladder. Two patients remain alive, 5 and 6 years following radical cystoprostatectomy; five died of cancer-specific causes. CONCLUSIONS Malignancy following enteric bladder augmentation arose in 4.5% (7/153) of our patients and was associated with coexisting carcinogenic stimuli (prolonged tobacco/chronic immunosuppressive exposure), or alternatively with the inherent risk of malignancy existing with bladder exstrophy.

Abstract
PURPOSE Patients with neurogenic bladder dysfunction due to spina bifida have been reported to be at increased risk for bladder cancer. Recent publications suggest that bladder augmentation is also a significant risk factor. We reviewed our experience with treating patients with spina bifida and bladder cancer. MATERIALS AND METHODS Patients with spina bifida treated for bladder cancer between 1995 and 2005 were identified. Patient demographics, mode of bladder management, risk factors and presenting symptoms were recorded along with therapy, pathological findings and outcome. This patient cohort was combined with all prior known published studies for analysis. RESULTS Eight patients with a median age of 41 years were treated. Only 1 patient (13%) had undergone bladder augmentation. Locally advanced stage (T3 or greater) or lymph node metastases were present in 88% of cases. Median survival was 6 months with only 1 patient alive with no evidence of recurrence at 20 months. A total of 11 prior published cases were identified and combined with this series. Transitional cell carcinoma was present in 58% of patients. Median survival was 6 months. Only 37% of patients had undergone bladder augmentation. CONCLUSIONS Patients with spina bifida and bladder cancer present at a young age with variable tumor histology and advanced stage, and they have poor survival. Presenting symptoms are often atypical and bladder cancer should be a consideration in this patient population, even in young adults. Due to poor survival further study is warranted in this population to determine whether screening would be beneficial for earlier detection and improved outcomes.

Abstract
OBJECTIVE Tumors arising within augmentation cystoplasties are aggressive, have poor prognosis and the majority are not detected at follow-up cystoscopy. Genetic changes in tumors precede morphological abnormalities. Therefore, the aim of this study was to investigate whether genetic abnormalities detected by comparative genomic hybridization (CGH) could be used to identify those patients with augmentation cystoplasties at increased risk of tumorigenesis. METHODS Bladder biopsy samples were obtained from 16 augmentation cystoplasty patients both distant from and near to the enterovesical anastomosis. CGH was used to detect genetic abnormalities in DNA extracted from the biopsies, archival specimens of two augmentation cystoplasties and two de novo bladder adenocarcinomas. RESULTS A greater number of amplifications on 2p, 3q, 8q, 9p, 17p, 18pq and 20pq, were observed in bladder biopsies obtained near to the enterovesical anastomosis compared to those taken distant to the suture line. CGH of archival augmentation cystoplasty tumor DNA indicated abnormalities at several loci with amplifications at 2q, 5q, 10p and 21pq, while deletions occurred at 5p and 16p. CONCLUSIONS The results of this study suggest that the urothelium adjacent to the bladder and/or bowel anastomosis in augmentation cystoplasties is genetically unstable. Furthermore, longitudinal studies are required to establish whether or not patients exhibiting genetic instability following augmentation cystoplasty are at greater risk of developing tumors than those with genetically stable epithelia.

Abstract
AIMS The vast majority of spinal cord lesions cause neurogenic bladder disorders. Detrusor hyperreflexia presents a major risk factor for renal damage in these patients. We evaluated the long-term results of patients with spinal cord injury treated at our institution. METHODS Eighty spinal cord injury patients (60 male, 20 female; mean age 29.6 years) with at least one follow-up visit a year for a minimum of five consecutive years, were included in this retrospective analysis. Follow-up included urodynamic evaluation, sonography of the upper and lower urinary tract, urine examination, and evaluation of renal function. Treatment modifications were based on the urodynamic findings. RESULTS Mean follow-up was 67.3 months (range 60-103 months). At initial presentation, 51 patients performed intermittent catheterization, 7 had indwelling catheters, 10 utilized reflex voiding, 2 patients presented with a Brindley stimulator, 10 patients used abdominal straining. At the end of our study, no patient had signs of renal damage. To achieve that goal, 8 patients underwent sphincterotomy, 3 received a Brindley stimulator, 3 underwent bladder augmentation, one Kock pouch was performed, and 12 patients were treated with botulinum-A-toxin injections in the detrusor. Twenty-two patients received intravesical anticholinergic therapy. In merely three patients, treatment was not modified during the entire follow-up. CONCLUSIONS In the long term, treatment strategy of neurogenic bladder dysfunction in patients with spinal cord injury had to be modified in almost all patients. 18.8% underwent surgery. For protection of the upper urinary tract and maintenance of continence, regular urodynamic follow-up is warranted.

Abstract
Among the many sites for primary small cell cancer is the genitourinary system. The majority of cases have been observed in the bladder and prostate. Small cell carcinoma accounts for less than 1% of all bladder tumors. Definitive predisposing factors are unknown; however, small cell carcinoma of the bladder has been associated with cigarette smoking, long-standing cystitis, bladder calculus, and augmented cystoplasty. Contrary to the early theory of derivation from Kulchitsky cells, it is now believed that small cell carcinoma of the bladder originates from the totipotent stem cells present in the submucosa of the bladder wall. A number of chromosomal aberrations have been reported in small cell cancer of the bladder. There are no specific clinical features that differentiate these patients from transitional cell carcinoma of the bladder; however, some patients may have associated paraneoplastic conditions. Diagnosis is established by cystoscopic-assisted biopsy. Like small cell carcinoma of the lung, small cell carcinoma of the bladder has a propensity for early metastases. There is no standard therapy for small cell carcinoma of the bladder and the prognosis is poor; however, patients treated with cisplatin-based chemotherapy regimens seem to have a better prognosis.

Abstract
A case of tubulovillous adenoma arising in an augmented bladder is described. Ureteroileal substitution and ileocystoplasty was performed when the patient was 18 years old. She noticed gross hematuria 44 years after the surgery. Cystoscopy revealed a non-papillary multiple tumor at the site of ileovesical anastomosis and transurethral resection biopsy was performed. Histopathological examination revealed a tubulovillous adenoma. A tubulovillous adenoma developing at the augmented bladder is rare. To our knowledge, this is the second case in which a tubulovillous adenoma developed in an augmented bladder.

Abstract
The overactive bladder is a common condition, which has significant effects on quality of life. The aetiology in most cases is unknown, and treatment outcomes have until recently been unsatisfactory. Management includes excluding pathology and implementing behavioural changes such as caffeine reduction, bladder and pelvic floor training, as well as antimuscarinic drug therapy. Compliance is often problematic, and this can be improved with some of the newer antimuscarinics with fewer side-effects, and a good therapist/patient relationship. In the majority of cases this 'treatment package' is successful, but in those where it is not, intravesical therapies have been introduced, e.g. neuromodulation, alternative drug therapies (e.g. vanilloids, botox) and surgery. With a better understanding of the aetiology and identification of risk factors better outcomes from treatment are likely.

Abstract
PURPOSE The aim of this study was to investigate the long-term histologic changes after bladder augmentation with gastric segment in an animal subject. MATERIALS AND METHODS Gastrocystoplasty was performed in 13 young, 3-month-old male rabbits. Open biopsies were taken from the native bladder and the gastric segment preoperatively and at 3, 6, and 12 months postoperatively. Sections were examined with H&E and periodic acid-Schiff (PAS) staining. Indirect immune peroxidase method was additionally applied to detect the carcinoembrionic antigen, the proliferative activity, and the gene for the tumor protein p53 in the epithelium. RESULTS On the native bladder, at the 3-month follow-up, polyps, mucosal edema, submucosal fibrosis, and squamous cell metaplasia were detected, which did not change during the follow-up. On the gastric segment, at the 3-month follow-up, parietal cell hyperplasia and inflammatory mucosal overgrowth were detected; at the 6-month follow-up, inflammation or atrophy of the gastric mucosa and colonic-type metaplasia was found. These alterations remained unchanged during later course of follow-up. Neither dysplasia nor malignancy was observed during the 12-month follow-up. CONCLUSIONS The present study supports the clinical observations of low cancer risk after gastrocystoplasty and may indicate different effect of gastric secretion on uroepithelium and that of urine on gastric mucosa.

Abstract
The objective of the study was to evaluate the effectiveness of an implant of porcine dermis to augment the bladder in women with refractory overactive bladder syndrome (OAB). Twelve women underwent a Pelvicol bladder augmentation. A visual analogue score for severity of incontinence and a quality of life questionnaire was carried out pre-operatively and at 12 months post-operatively. Follow up cystoscopy was carried out in three women in addition. Three women were dry and cured; five women were significantly improved; two women were slightly improved and the procedure was unsuccessful in the remaining two women. There were no significant complications and voiding was spontaneous in every case. A bladder augmentation using porcine dermis may have a role in the surgical management of non-neuropathic women with OAB that has failed to respond to conservative therapy.

Abstract
PURPOSE We present our experience with urethral recurrence of transitional cell carcinoma following cystectomy and orthotopic urinary diversion in a contemporary series. MATERIALS AND METHODS Between June 1995 and December 2001, 415 patients underwent radical cystectomy for transitional cell carcinoma. Of those patients 196 (47.2%) received an orthotopic urinary diversion. Demographics, clinical characteristics, pathological stage and patient outcomes were reviewed. RESULTS Mean followup was 34.1 months (range 0.3 to 97.3). Of the 196 patients who underwent orthotopic diversion 59 (30.1%) had T3 or greater disease on final pathological evaluation. Thirteen patients (6.6%) were found to have prostatic urethral involvement while 83 (42.3%) had elements of carcinoma in situ. No patient with prostatic urethral involvement had subsequent urethral recurrence. Overall only 1 patient (0.5%) had urethral recurrence of transitional cell carcinoma following orthotopic urinary diversion. The urethral recurrence rate in patients with orthotopic diversion was less than in patients with ileal conduit creation during the same period (2.1%). The overall disease recurrence rate following orthotopic diversion was 31.6% (62 of 196). CONCLUSIONS Urethral recurrence following orthotopic neobladder was rare in this series despite using selection criteria that were less stringent than those of other comparable series. Overall disease recurrence was relatively high in patients with high risk pathological features but urethral recurrence in this group with orthotopic urinary diversion remained low.

Abstract
PURPOSE Cancer following augmentation cystoplasty is a recognized risk factor. The procedure has only gained popularity in pediatric urology within the last 25 years, limiting the population being studied by statistical power and the lack of long-term followup. The majority of reported cases of post-augmentation malignancy have occurred in adults with multiple risk factors. Currently the most common indication for augmentation cystoplasty in children and adolescents is neuropathic bladder. We review 3 cases of transitional cell carcinoma (TCC) following augmentation cystoplasty in this unique population with no additional risk factors for bladder cancer. MATERIALS AND METHODS We reviewed our clinical database of children and adolescents who underwent bladder augmentation since 1978 to evaluate the incidence of cancer. This study represents a captured population within a single institutional practice. There were 483 cases entered into the database, and particular attention was paid to 260 augmentations with at least 10 years of followup. We reviewed medical history, clinical outcomes, cancer risk factors, augmentation type and pathology of the 3 patients who presented with TCC after augmentation cystoplasty. RESULTS Three patients presented with grade 2 to 3 TCC following bladder augmentation, all of whom underwent exploratory laparotomy and eventually died of metastatic disease. No patient had a history of smoking exposure greater than 10 packs per year or other known risk factors for bladder cancer. Two patients had an ileocecal augmentation and 1 had a cecal augmentation for neuropathic bladder. Patient age at augmentation was 8, 20 and 24 years, and age at diagnosis of TCC was 29, 37 and 44 years, respectively. Mean time from augmentation to TCC was 19 years. Assuming a 10-year lag period before the risk of cancer, in at least 1.2% of bladder augmentation cases in our database cancer has developed. CONCLUSIONS This study supports the hypothesis that bladder augmentation appears to be an independent risk factor for TCC, with a lag time of less than 20 years. We recommend endoscopic surveillance of all patients with a history of bladder augmentation beginning 10 years after initial surgery.

Abstract
PURPOSE Tumor development following ureterosigmoidostomy is a worldwide accepted late complication. In contrast, tumor risk in other forms of urinary diversion with the separation of urine and feces is still unclear. We present a complete and detailed analysis of all reported tumors following urinary diversions using isolated gut segments in the literature. We estimated the tumor risk in comparison to ureterosigmoidostomies and to the general population. MATERIALS AND METHODS We reviewed the world literature up to April 2003 via MEDLINE for secondary tumors in urinary diversions using isolated intestinal segments. RESULTS We found 81 tumor case reports following urinary diversion using isolated intestinal segments. Tumors developed in 18 conduits, 45 cystoplasties, 5 rectal bladders, 3 neobladders, 6 colonic pouches and 4 ileal ureter replacements. CONCLUSIONS All urinary diversions using bowel with or without separation of urine and feces carry a significantly higher tumor risk for intestinal tumor development compared to the general population. The tumor spectrum and tumor location in isolated gut segments are different than tumors following ureterosigmoidostomies but the total tumor risk is probably similar. The latency period depends on the initial diagnosis with malignant diseases leading to a shorter induction time. Concerning etiology, many theories exist but the exact mechanism remains unclear. Regular endoscopic control beginning with postoperative year 3 for early detection of secondary malignancies is mandatory.

Abstract
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.

Abstract
Tumours developing after urinary tract or bladder reconstruction with intestinal tissue have well been described. Adenocarcinomas and transitional cell carcinomas are the most frequent histological features. We report here a case of small cell carcinoma developing after augmentation enterocystoplasty. This rare observation is an opportunity to review the literature about extrapulmonary small cell carcinoma and tumours developing after uro-intestinal reconstruction surgery.

Abstract
Most tumors arising after augmentation ileocystoplasty have been reported to develop adjacent to the ileovesical anastomosis. Herein, we report a case of adenocarcinoma arising at the ileoileal anastomotic site 33 years after augmentation ileocystoplasty (Scheele's ring plasty) for tuberculous contracted bladder. The present case shows the possibility of late malignancy developing at the ileoileal junction after ileal neobladder.

Abstract
PURPOSE To assess the feasibility of transplanting adult bladder tissue to its offspring as a source of neobladder tissue for bladder augmentation. METHODS The dome of the bladder of an adult Lewis rat was excised and transplanted into the omentum of a 6-week-old offspring (living-related partial bladder transplant: n = 15). The bladder remnant of the donor rat was closed. Two weeks after transplantation, a laparotomy was performed to mobilize the bladder graft with its omental pedicle into the pelvis. Bladder augmentation (BA) was performed by anastomosing the graft to the recipient's bladder. Thirty days after BA, the entire neobladder was excised and histopathologically examined. RESULTS At laparotomy, each bladder graft appeared macroscopically as a thin-walled cyst in the recipient's omentum. Each graft could be mobilized into the pelvis and anastomosed to the recipient's bladder. BA was successful in all 15 recipients, and histopathologic studies showed that the mucosa was normal throughout each neobladder. Postoperatively, donors and recipients were clinically well without any sign of urinary incontinence or obstruction. CONCLUSIONS This is the first report of adult tissue being transplanted successfully into a recipient without vascular reconstruction in a rat. Living-related partial bladder transplantation for the purpose of BA is feasible using our technique and could have application as an alternative technique for BA in a rat.

Abstract
Urinary bladder augmentation with segments of the stomach (gastrocystoplasty), small bowel, or large intestine (enterocystoplasty) improves capacity and compliance in patients with bladder dysfunction. Although malignant complications of enterocystoplasty have been reported, the risk of malignancy in the setting of gastrocystoplasty is not known. We describe the case of a 73-year-old woman who developed a transitional cell carcinoma associated with transitional cell metaplasia and dysplasia of the gastric epithelium 14 years following gastrocystoplasty. To our knowledge, this is the first reported case of a malignant complication of this surgical procedure. We conclude that patients who have undergone gastrocystoplasty are at an increased risk for the development of malignancy in the neobladder and require close long-term follow-up, similar to patients who have undergone enterocystoplasty.

Abstract
The development of cancer on the ileal graft after augmentation ileocystoplasty for benign bladder disease is a little known complication. The authors report a case of squamous cell carcinoma in the ileal bladder occurring 37 years after augmentation ileocystoplasty for tuberculous bladder, in a 68-year old patient. Carcinomatous degeneration is usually occurs more than ten years after cystoplasty. Patients treated by this operation must be submitted to annual cystoscopy combined with guided biopsies at the slightest doubt. This surveillance should be started between the 5th and the 10th postoperative year.

Abstract
OBJECTIVES To evaluate the microbiologic characteristics of enterocystoplasty urine and assess the influence of bacteria type and effect of prophylactic and therapeutic antibiotic administration on the urinary nitrosamine levels of patients with enterocystoplasty. Nitrosamines have been implicated in the development of cancer in patients with an enterocystoplasty. Urinary tract infection (UTI) is associated with elevated nitrosamine levels. METHODS Urine samples were collected to determine the urinary nitrosamine levels and for microscopy, culture, and sensitivity from 42 patients with an enterocystoplasty and 6 normal controls. A subgroup of 5 enterocystoplasty patients with proven UTI was also evaluated by measuring the urinary nitrosamine levels before and after a therapeutic course of antibiotics. RESULTS Of the 42 cystoplasty patients, 22 had a proven UTI; none of the controls had one. Sixteen of the cystoplasty patients were taking prophylactic antibiotics and had mean N-nitrosamine levels equivalent to the control levels. The mean nitrosamine levels were highest in patients with a UTI (1.9 micromol/L). Escherichia coli was the most common infecting organism (11 patients) and resulted in the highest mean nitrosamine levels (2.1 micromol/L). The nitrosamine levels fell with UTI treatment to within the control range. CONCLUSIONS UTI occurs in 51% of enterocystoplasty patients and is associated with elevated mean urinary nitrosamine levels. E. coli is the infecting organism in 50% of cases. Antibiotic prophylaxis reduces the nitrosamine levels to those of the controls. UTI treatment results in a rapid reduction of elevated nitrosamine levels to control levels.

Abstract
OBJECTIVE When conservative treatment for bladder overactivity fails the "clam" ileocystoplasty has been proposed to restore continence and preserve urethral voiding. This study presents our experience with this technique. MATERIALS AND METHODS Thirty patients, 4 men and 26 women, with a mean age of 50.3 years (range 21-71 years) were operated upon. Five patients had an incomplete spinal lesion and detrusor hyperreflexia, 25 subjects had an idiopathic, unstable detrusor. The ileocystoplasty was combined with a colposuspension procedure in 8 patients. In one patient simultaneous repair of an urethro-vaginal fistula was performed using omentum flap interposition. The mean follow-up was 60 months (range 4-127). RESULTS To the surgeon, 27 patients (90%) reported satisfaction with bladder control and relief of symptoms at follow-up. When asked by a nurse in a written questionnaire, 18 out of 23 patients (78%) were quite happy with their bladder function postoperatively. No serious complications to surgery were noted. Postoperatively, 11 patients used self-intermittent catheterization and one, by choice, preferred an indwelling catheter. Due to failure, two patients later underwent reoperation with urinary diversion and one further patient required an additional artificial sphincter. Metabolic consequences owing to enteric malabsorption were infrequent and of a mild nature. No malignant change was identified. CONCLUSION In patients with refractory overactive bladder, we found the "clam" ileocystoplasty to be an effective technique for symptom reduction and increased quality of life.

Abstract
OBJECTIVES Detrusor hyperreflexia with elevated storage pressures presents a major risk factor for renal damage in patients with neurogenic lower urinary tract dysfunction. If standard anticholinergic treatment is unsuccessful, surgical treatment must be considered. We evaluated the effects of intravesical oxybutynin treatment on detrusor hyperreflexia in patients in whom standard oral treatment had failed. METHODS Twenty-five patients (mean age 36. 7 years) with storage pressures greater than 40 cm H(2)O despite standard anticholinergic treatment received intravesical (15 mg three times daily) and oral oxybutynin chloride treatment. The follow-up evaluations included urodynamic testing, renal ultrasound, urine examination (urinalysis and urine culture), and evaluation of side effects. RESULTS The mean follow-up was 6 months. Intravesical treatment led to an increase in bladder storage volume from 349 to 420 mL. The mean maximum storage pressure was significantly reduced from 54 to 26.5 cm H(2)O. Detrusor storage pressures returned to values less than 40 cm H(2)O in 21 of 25 patients. Dysreflexia was treated successfully in 3 of 5 patients. No patient developed renal damage. No severe side effects or drug-related discontinuation of treatment were observed. CONCLUSIONS Intravesical oxybutynin therapy seems to be a safe and effective treatment option for detrusor hyperreflexia in adults and avoids surgical treatment in most patients. Long-term observations concerning side effects, acceptance, and efficacy are needed.

Abstract
PURPOSE The aim of this study was to examine the histopathology of neobladder mucosa biopsy specimens obtained routinely as part of postsigmoidocolocystoplasty (SCP) follow-up. METHODS One hundred cases of SCP (mean age at surgery, 10.6 years) performed by the authors were examined for the presence of dysplasia or malignant changes in the mucosa of the neobladder using H&E and proliferating cell nuclear antigen (PCNA) staining. RESULTS No dysplastic or malignant changes were identified in any case. Metaplasia was found in 5 cases and hyperplasia in 2. There were no major differences found on H&E and PCNA staining of specimens obtained after different periods of follow-up post-SCP; follow-up was short term (up to 5 years) in 44 cases, medium term (from 5 to 10 years) in 48 cases, and long term (over 10 years) in 8 cases. PCNA staining was significantly more intense in subjects who stopped regular bladder irrigations (BI) post-SCP and in subjects in whom bladder stones developed (P < .05; Welch's t test), compared with subjects who continued BI and subjects in whom bladder stones did not develop. CONCLUSIONS After SCP, patients are advised to continue BI. Regular biopsies should be part of routine follow-up, especially in subjects with bladder stones.

Abstract
Augmentation cystoplasty is associated with an increased risk of bladder cancer development between 10 and 20 years after augmentation. Using microsatellite analysis, we analyzed urine obtained before surgical resection of the malignant lesion from a patient who developed invasive adenocarcinoma after augmentation cystoplasty. Loss of heterozygosity was identified in both urine and tumor samples from this patient. This observation suggests that microsatellite urine analysis may be useful as a monitoring tool for patients after augmentation cystoplasty.

Abstract
PURPOSE Ureter is one of the best tissues for bladder augmentation. The amount of ureteral segment available is extremely variable among patients. We compared results in patients who underwent ureterocystoplasty with 2 ureters, 1 complete ureter or a distal segment only after transureteroureterostomy. MATERIALS AND METHODS During a 6-year period we performed 32 ureterocystoplasties at 2 pediatric centers in Argentina (16) and Chile (16). Median patient age at surgery was 9 years (range 4 months to 20 years). Clinical presentation included urinary infection, hydronephrosis, incontinence and undiversion. The diagnosis was neurogenic bladder in 20 cases, infravesical obstruction in 7, massive reflux in 3 and ureterocele in 2. All patients had poor bladder compliance and vesicoureteral reflux. We used different options to augment the bladder, including 2 ureters in 5 patients, bilateral nephrectomy in 3, a complete duplex system in 1 and a bilateral partial ureter in 1 (group 1); a complete ureter in 14 (group 2), and a distal segment of ureter with transureteroureterostomy in 13 (group 3). When transureteroureterostomy was performed, a suprapubic tube remained indwelling for 2 weeks and a Double-J stent was placed for 1 month. Median followup was 16 months (range 4 months to 6 years). Clinical and radiological evaluations, including ultrasound, cystography, urodynamics, renal scan and renal function measurement, were done 4 months postoperatively and twice yearly thereafter as needed. RESULTS We noted no significant difference in bladder capacity when 1 or 2 ureters were used. Median increase in bladder capacity in groups 1 and 2 was 375% (range 80 to 800). All patients who received a complete segment of ureter had clinical improvement, decreased hydronephrosis and resolution of reflux with improved bladder compliance. When a partial segment of ureter was used median capacity increased 230% (range 40 to 400) with clinical improvement in 12 patients (92.3%). Compliance improved, which led to longer intervals between clean intermittent catheterizations. No patient has needed repeat augmentation to date. CONCLUSIONS There is a difference in median increased bladder capacity when a segment of distal ureter is used to augment the bladder versus 1 or 2 whole ureters. However, the use of distal ureter still represents a safe alternative for augmenting the bladder and simultaneously resolving massive reflux. Ureterocystoplasty is an excellent choice for increasing bladder capacity and improving bladder compliance despite the different amounts of tissue available.
