Fate of the Leftover Bladder After Supravesical Urinary Diversion for Benign Disease

[Urinary diversion with or without simple cystectomy as a salvage option for benign diseases of the lower urinary tract]

Benign diseases of the lower urinary tract can occur as a result of oncological or neurological diseases or their respective therapies (e.g., surgery or radiation treatment) and can significantly reduce the quality of life for affected patients. Urinary diversion serves as a salvage option when all other therapeutic regimens have been carried out and proven unsuccessful. When selecting the suitable urinary diversion, a comprehensive clinical assessment of the patients is required in order to ensure long-term success. In some cases, a cutaneous, catheterizable pouch offers the last and only option for a long-term and definitive treatment of a patient's condition. Overall, a decreasing trend in the establishment of a continent urinary diversion is observed in Germany. Current data on benign indications for urinary diversion are limited. Therefore, further data collection and research are needed.

Pelvic Extirpative Surgery for the "End-Stage Irradiated Bladder"

Men with prostate cancer have the daunting task of selecting from multiple modalities of treatment. The long-term effects of radiation therapy are only now being recognized. For both patients and surgeons, the end-stage irradiated bladder poses numerous problems and challenges. Specifically, irradiated bladders with urosymphyseal fistula, radiation cystitis, and rectourethral fistula are challenging to manage and treat. This review outlines the presentation, workup, and management including cystectomy for these three devastating late complications of radiation therapy. There are special considerations when performing benign cystectomy that are not typically considered during oncologic cystectomy. We discuss an overview of the current literature regarding the "end-stage bladder" resulting from radiation therapy and the important considerations that must be acknowledged when managing these patients. It is shown that many of the less invasive and conservative options ultimately lead to cystectomy. Indeed, our review concludes that cystectomy with urinary diversion is a safe and viable option in select irradiated patients with the goal to improve quality of life.

[Guidelines on the urological management of the adult patient with spinal dysraphism (spina bifida)]

INTRODUCTION

Improved life expectancy and prenatal screening have changed the demographics of spina bifida (spinal dysraphism) which has presently become a disease of adulthood. Urinary disorders affect almost all patients with spinal dysraphism and are still the leading cause of mortality in these patients. The aim of this work was to establish recommendations for urological management that take into account the specificities of the spina bifida population.

MATERIALS AND METHODS

National Diagnosis and Management Guidelines (PNDS) were drafted within the framework of the French Rare Diseases Plan at the initiative of the Centre de Référence Maladies Rares Spina Bifida - Dysraphismes of Rennes University Hospital. It is a collaborative work involving experts from different specialties, mainly urologists and rehabilitation physicians. We conducted a systematic search of the literature in French and English in the various fields covered by these recommendations in the MEDLINE database. In accordance with the methodology recommended by the authorities (Guide_methodologique_pnds.pdf, 2006), proposed recommendations were drafted on the basis of this literature review and then submitted to a review group until a consensus was reached.

RESULTS

Bladder dysfunctions induced by spinal dysraphism are multiple and varied and evolve over time. Management must be individually adapted and take into account all the patient's problems, and is therefore necessarily multi-disciplinary. Self-catheterisation is the appropriate micturition method for more than half of the patients and must sometimes be combined with treatments aimed at suppressing any neurogenic detrusor overactivity (NDO) or compliance alteration (anticholinergics, intra-detrusor botulinum toxin). Resort to surgery is sometimes necessary either after failure of non-invasive treatments (e.g. bladder augmentation in case of NDO resistant to pharmacological treatment), or as a first line treatment in the absence of other non-invasive alternatives (e.g. aponeurotic suburethral tape or artificial urinary sphincter for sphincter insufficiency; urinary diversion by ileal conduit if self-catheterisation is impossible).

CONCLUSION

Spinal dysraphism is a complex pathology with multiple neurological, orthopedic, gastrointestinal and urological involvement. The management of bladder and bowel dysfunctions must continue throughout the life of these patients and must be integrated into a multidisciplinary context.

Urinary Diversion With or Without Concomitant Cystectomy for Benign Conditions: A Comparative Morbidity Assessment According to the Updated European Association of Urology Guidelines on Reporting and Grading of Complications

BACKGROUND

Evidence is scarce on morbidity after urinary diversion ± cystectomy as treatment for benign bladder indications.

OBJECTIVE

To conduct a morbidity assessment and to evaluate the impact of concomitant subtrigonal cystectomy (SC) versus urinary diversion (UD) alone.

DESIGN, SETTING, AND PARTICIPANTS

This was a retrospective study of 97 patients with benign bladder conditions between 2009 and 2017.

INTERVENTION

Open UD and/or concomitant SC.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Data for 30-d complications were extracted using a procedure-specific catalog and were graded according to the Clavien-Dindo classification (CDC), and Comprehensive Complication Index (CCI) values were calculated. Traditional morbidity endpoints focused on the comparative morbidity of UD + SC versus UD alone. Multivariable regressions were computed to evaluate the impact of SC versus UD alone on cumulative morbidity. Subgroup analyses were repeated for patients with previous irradiation.

RESULTS AND LIMITATIONS

Of 97 patients, 46 (47%) underwent UD + SC and 51 (53%) underwent UD alone. Forty-nine patients (51%) had a history of abdominopelvic radiotherapy. Overall, 69 (71%) patients underwent continent UD and 26 (27%) underwent a Mitrofanoff procedure. We registered 390 complications in 97 (100%) patients, the majority of which were classified as minor (CDC grade ≤IIIa; 93%). Overall, three patients (3.1%) were readmitted and no patient died within 30 d. On multivariable analyses, neither concomitant SC nor previous radiotherapy was associated with higher cumulative morbidity (all p = 0.2). Similarly, concomitant SC was not predictive of a higher complication burden in the irradiation subgroup (all p ≥ 0.05). Limitations include heterogeneity for indications and a lack of information on the radiation dose and field.

CONCLUSIONS

In a high-volume referral center, neither SC nor abdominopelvic radiotherapy increased perioperative cumulative morbidity for patients with benign bladder conditions undergoing UD. This is particularly relevant for patients who would benefit from concomitant SC to avert adverse sequelae related to the retained bladder.

PATIENT SUMMARY

Urinary diversion (UD) is a surgical procedure to create a new way for urine to exit the body. We found that among patients undergoing UD for benign bladder conditions, those who also have their bladder removed and patients who have received previous radiotherapy do not experience more complications.

Cystectomy for Benign Indications

PURPOSE OF REVIEW

This article evaluates the historical influences, current use, surgical techniques, and recent evidence on outcomes for cystectomy performed for benign indications.

RECENT FINDINGS

At the population level, cystectomy for benign indications has similar perioperative morbidity to radical cystectomy for cancer. Postoperative patient satisfaction is high and functional outcomes appear good, including sexual function. Patient regret about diversion choice is low provided decisions are well informed. Cystectomy is important both as a primary procedure for benign disease and as an adjunct to primary urinary diversion. Early morbidity remains high but long-term results are encouraging. Further studies are needed to guide patient decision-making, to help inform diversion choice, and to understand the long-term impact of surgery and diversion choice on quality of life.

Cystectomy and ileal conduit for neurogenic bladder: Comparison of the open, laparoscopic and robotic approaches

AIM

The objective of the present study was to compare the outcomes of open versus laparoscopic versus robotic cystectomy and ileal conduit for neurogenic lower urinary tract dysfunction (NLUTD).

METHODS

The charts of all patients who underwent cystectomy and ileal conduit for NLUTD between January 2004 and November 2020 in an academic center were retrospectively reviewed. The approach was either open, laparoscopic or robot-assisted depending on the period (i.e., three consecutive era). For the robotic approach, the diversion was done either intracorporeally or extracorporeally. We compared the perioperative and late postoperative outcomes between the three groups.

RESULTS

After exclusion of 10 patients with non-neurogenic benign conditions, 126 patients were included over the study period. The most frequent neurological conditions were multiple sclerosis (36.5%) and spinal cord injury (25.4%). The approach was open, laparoscopic or robot-assisted in 31 (24.6%), 26 (20.6%) and 69 (54.7%) cases respectively. Seventy-two patients experienced a 90-day postoperative complication (57.1%) of which 22 had a major complication (Clavien 3 or higher, 17.5%) including one death (0.8%). The rate of major postoperative complications was significantly lower in the robotic group (23% vs. 23% vs. 10%; p = 0.049) while the rate of overall complications was comparable across the three groups (58.1% vs. 53.9% vs. 60.6%; p = 0.84). After a median follow-up of 23 months, 22 patients presented a late complication (17.6%), mainly incisional hernia (5; 4%) and uretero-ileal stricture (9; 7.2%). The rate of late complications did not differ significantly between the three approaches.

CONCLUSION

Cystectomy and ileal conduit for neurogenic bladder is associated with a relatively high perioperative morbidity. The robot-assisted approach may decrease the risk of major postoperative complications.

Dissecting the role of radical cystectomy and urinary diversion in post-operative complications: an analysis using the American College of Surgeons national surgical quality improvement program database

OBJECTIVE

To characterize the contribution of the extirpative and reconstructive portions of radical cystectomy (RC) to complications rates, and assess differences between urinary diversion (UD) types.

MATERIALS AND METHODS

We conducted a retrospective cohort study comparing patients undergoing UD alone or RC+UD for bladder cancer from 2006 to 2017 using ACS National Surgical Quality Improvement Program database. The primary outcome was major complications, while secondary outcomes included minor complications and prolonged length of stay. Propensity score matching (PSM) was utilized to assess the association between surgical procedure (UD alone or RC+UD) and outcomes, stratified by diversion type. Lastly, we examined differences in complication rates between ileal conduit (IC) vs. continent UD (CUD).

RESULTS

When comparing RC + IC and IC alone, PSM yielded 424 pairs. IC alone had a lower risk of any complication (HR 0.63, 95% CI 0.52-0.75), venous thromboembolism (HR 0.45, 95% CI 0.22-0.91) and bleeding needing transfusion (HR 0.41, 95% CI 0.32-0.52). This trend was also noted when comparing RC + CUD to CUD alone. CUD had higher risk of complications than IC, both with (56.6% vs 52.3%, p = 0.031) and without RC (47.8% vs 35.1%, p=0.062), and a higher risk of infectious complications, both with (30.5% vs 22.7%, p< 0.001) and without RC (34.0% vs 22.0%, p=0.032).

CONCLUSIONS

RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, CUD had a higher risk of post-operative complication than IC.

Robot-assisted Cystectomy with Intracorporeal Urinary Diversion After Pelvic Irradiation for Prostate Cancer: Technique and Results from a Single High-volume Center

BACKGROUND

Radiation therapy (RT) for prostate cancer (PCa) treatment is burdened by high rates of late urinary adverse events (UAEs). The feasibility of robot-assisted cystectomy (RAC) with intracorporeal urinary diversion (ICUD) for treatment of high-grade UAEs has never been assessed.

OBJECTIVE

To report perioperative outcomes, early (≤90 d) and late (>90 d) complications among patients undergoing RAC for UAEs after RT.

DESIGN, SETTING, AND PARTICIPANTS

We retrospectively evaluated 32 patients undergoing RAC with ICUD for UAEs in a single tertiary centre.

SURGICAL PROCEDURE

Surgery was performed using a da Vinci Xi system with adaptation for the primary treatment.

MEASUREMENTS

Perioperative outcomes included estimated blood loss (EBL), operative time (OT), intraoperative complications, and length of stay (LOS). Data for early and late postoperative complications were collected using the quality criteria recommended by the European Association of Urology. Univariate logistic regressions were performed to test the effect of baseline and perioperative characteristics on early postoperative complications.

RESULTS AND LIMITATIONS

The median age-adjusted Charlson comorbidity index (ACCI) was 6 (IQR 5-7). The indication for RAC was hemorrhagic radiation cystitis in 29 cases (91%), contracted bladder in two cases (6.2%), and urinary fistula in one case (3.1%). The median EBL, OT, and LOS were 250 ml, 330 min, and 10 d, respectively. A total of 31 (97%) patients received an ileal conduit. The 90-d rate of Clavien-Dindo grade ≥IIIa complications was 28%. The late complication rate was 46% and the perioperative mortality rate was 0%. On univariate analyses, ACCI was the only parameter correlated with the risk of early complications (odds ratio 1.75, 95% confidence interval 1.05-2.9; p =  0.03). The median follow-up was 30 mo (IQR 15-40). The lack of comparison with open cystectomy represents the main limitation.

CONCLUSIONS

RAC for UAEs in patients with a history of pelvic irradiation is a feasible option in high-volume centers. The use of new technologies can help to overcome some of the technical difficulties and reduce the risk of perioperative and late complications.

PATIENT SUMMARY

We report our experience with robot-assisted surgery for removal of the bladder in the management of urinary problems after radiation therapy for prostate cancer. When performed by highly experienced surgeons, this is a feasible procedure with outcomes and early and late complication rates that are acceptable.

Cancer survivorship issues with radiation and hemorrhagic cystitis in gynecological malignancies

PURPOSE

Given that more cancers are being diagnosed earlier and that treatment of cancer is improving, health issues of cancer survivors are becoming more common and apparent. Pelvic radiation therapy for the treatment of gynecological cancers can lead to long-term collateral damage to the bladder, a condition termed radiation cystitis (RC). Late sequelae may take many years to develop and include incontinence and pain as well as hematuria. RC is a rare but potentially life-threatening condition for which there are few management and treatment options.

METHODS

There are limited data in the literature regarding the effects of radiation on the bladder after gynecological cancer therapy and we hereby review the literature on cancer survivorship issues of pelvic radiation for gynecology literature.

RESULTS

Treatment options are available for patients with radiation-induced hemorrhagic cystitis. However, most treatments are risky or only effective for a short timeframe and no therapy is currently available to reverse the disease progress. Furthermore, no standardized guidelines exist describing preferred management options. Common therapies include hyperbaric oxygen therapy, clot evacuation, fulguration, intravesical instillation of astringent agents, and surgery. Novel developing strategies include Botulinum Toxin injections and liposomal-tacrolimus instillations. These treatments and strategies are discussed.

CONCLUSIONS

In this review, we will present current and advanced therapeutic strategies for RC to help cancer survivors deal with long-term bladder health issues.

Challenges and Opportunities in Radiation-induced Hemorrhagic Cystitis

As diagnosis and treatment of cancer is improving, medical and social issues related to cancer survivorship are becoming more prevalent. Hemorrhagic cystitis (HC), a rare but serious disease that may affect patients after pelvic radiation or systemic chemotherapy, has significant unmet medical needs. Although no definitive treatment is currently available, various interventions are employed for HC. Effects of nonsurgical treatments for HC are of modest success and studies aiming to control radiation-induced bladder symptoms are lacking. In this review, we present current and advanced therapeutic strategies for HC to help cancer survivors deal with long-term urologic health issues.

[Laparoscopic cystectomy and ileal conduit urinary diversion for neurogenic bladders and related conditions. Morbidity and better quality of life]

OBJECTIVES

To assess morbidity and functional consequences of laparoscopic cystectomy with ileal conduit urinary diversion: in neurologic patients.

MATERIALS

We reviewed the records of forty-two patients (ten men and thirty-two women) who underwent surgery between August 2007 and October 2013. The median age of the patient was 54 years old (range between 21-79 years). A laparoscopic cystectomy was performed followed by a short laparotomy to perform the ileal conduit urinary diversion. Records were reviewed to retrieve the indications and describe the postoperative and functional course. Patients and GPs were interviewed during phone calls to appreciate the quality of life by the PGII scale in order to assess the functional outcome.

RESULTS

The operation was performed on 42 patients, of whom 18 had multiple sclerosis, nine a post-traumatic neurogenic bladder. Among the total population, 10 patients (23.81%) required a transfusion of at least one packed red blood cells (1-7). The overall rate of early complications was 35.71%. Belated complications were seen in 52.38% of the population. The median duration of hospital stay was 16 days (range between 9-70 days). The median follow up was 34 months (range between 1-76 months). For patients, the PGII scale rating had a median value of 6 (2-7). All referring physicians described a better functional status.

CONCLUSION

The laparoscopic cystectomy can make postoperative course smoother for the neurological patients. However, the surgeon must weigh individually the benefit of performing the operation.

Early urinary diversion with ileal conduit and vesicovaginostomy in the treatment of radiation cystitis due to carcinoma cervix: a study from a tertiary care hospital in South India

BACKGROUND

To study the magnitude of radiation cystitis following radiation therapy for carcinoma cervix, and propose an algorithm to decide on early diversion, with or without vesicovaginostomy.

METHODS

Women who developed radiation cystitis following radiotherapy for carcinoma cervix from January 1998 to December 2011 were included in this retrospective study. Electronic hospital records were analysed to document the presence of radiation cystitis. All women who developed evidence of radiation-induced cystitis, according to the common toxicity and Radiation Therapy Oncology Group criteria, were included in the study. We looked at transfusion requirements, number of hospital admissions, quality of life and cost involved. Chi-square tests were done where applicable. SPSS version 16 was used for analysis.

RESULTS

Of the 902 patients who received radiation for carcinoma cervix in the 13-year period, 62 (6.87%) developed grade 3/4 cystitis. Twenty-eight of them underwent ileal conduit diversion, with 18 undergoing concomitant vesicovaginostomy. When compared with the patients who did not have diversion, the transfusion requirements, number of hospital admissions and quality of life had a statistically significant difference. Cost analysis of early diversion too showed a marginal benefit with early diversion. The limitation of the study was that it was retrospective in nature.

CONCLUSION

In radiation cystitis, multiple hospital admissions and consequential increase in cost is the norm. In severe disease, early diversion is a prudent, cost-effective approach with good quality of life and early return to normal activity.

Managing urinary incontinence: what works?

Urinary incontinence is a common condition, which, although not life-threatening, impairs the health-related quality of life of affected individuals. All women complaining of incontinence require a basic assessment and those with complex or refractory symptoms may benefit from urodynamic studies. Initial treatment includes lifestyle advice, behavioral modifications, bladder retraining and pelvic floor muscle training. For those women with persistent stress urinary incontinence following conservative therapy, surgical management might be considered. The development of the minimally invasive, retropubic, synthetic, mid-urethral sling procedures has revolutionized stress incontinence surgery and reduced the popularity of 'traditional' procedures, such as colposuspension and autologous fascial sling. In an attempt to reduce further the morbidity, transobturator and single-incision slings have been introduced. While antimuscarinic agents are the mainstay of the current medical management of urgency urinary incontinence, a recently developed selective β3-adrenergic receptor agonist (mirabegron) offers an alternative pharmacological option. Modalities such as intravesical botulinum toxin and neuromodulation (peripheral or sacral) are available to women with refractory urgency incontinence. Finally, when all other options have been explored and proven unsuccessful, inappropriate or not feasible, reconstructive surgery or catheter insertion might be considered as a last resort. The aim of this paper is to review conservative, medical and surgical management for urinary incontinence by using the best available evidence in the literature.

Advances in Therapeutic Development for Radiation Cystitis

Radiation treatment for pelvic malignancies is typically associated with radiation injury to urinary bladder that can ultimately lead to radiation cystitis (RC). The late sequelae of radiation therapy may take many years to develop and include bothersome storage symptoms such as hematuria, which may be life-threatening in severe cases of hemorrhagic cystitis. Although no definitive treatment is currently available, various interventions are used for radiation and hemorrhagic cystitis including blood transfusion, bladder irrigation, intravesical instillation of substances such as alum, silver nitrate, prostaglandins or formalin, and fulguration of intravesical bleeding sites and surgery options such as supravesical urinary diversions and cystectomy. Effects of non-surgical treatments for radiation and hemorrhagic cystitis are of modest success and studies are lacking to control the effects caused by RC. When such measures have proven ineffective, use of bladder botulinum toxin injection has been reported. New therapy, such as intravesical immunosuppression with local tacrolimus formulation is being developed for the treatment of radiation hemorrhagic cystitis.

Options for independent bladder management in patients with spinal cord injury and hand function prohibiting intermittent catheterization

AIMS

Choosing the appropriate bladder management strategy for the spinal cord injury patient with neurogenic bladder and hand function prohibitive of self catheterization (urethral or stomal) catheterization is complex and based on limited literature. We have catalogued the available data in this review.

METHODS

A literature review was conducted on external sphincterotomy, suprapubic tube, ileal conduit, and ileovesicostomy between 1994 and 2012. Articles on neurogenic bladder focused primarily on spinal cord injury were included. Important aspects of each technique, patient selection, urologic events, and quality of life are described.

CONCLUSION

The available literature consists primarily of level 3 data. Patient reported outcomes were rarely measured. External sphincterotomy is a good option for males who are candidates for an external catheter and who wish to avoid a complicated reconstruction-most will need re-operations for failure. Suprapubic tube is an option in both genders. Complaints usually involve urine leakage and urinary tract infection, which typically resolve with conservative measures. There is some evidence to support patient satisfaction. Ileal conduit is an option for all patients with quadriplegia, offering continuous drainage and absence of foreign material. Many providers and patients will choose more conservative options first. The ileovesicostomy is best applied to small bladders with severe overactivity. The "reversibility" of this procedure makes it attractive to those not interested in an ileal conduit and who have had complications from prolonged suprapubic tube placement. The authors conclude with recommendations for future research, most importantly more standard reporting of objective data.

The management of overactive bladder refractory to medical therapy

Overactive bladder (OAB) is a clinical syndrome describing the symptom complex of urgency, with or without urgency incontinence and is usually associated with frequency and nocturia. Whilst many women may be initially managed using a clinical diagnosis alone a number will fail primary therapy and will require further investigation. Those women with refractory symptoms following initial conservative and medical therapy may benefit from alternative treatment modalities including intravesical Botulinum toxin, neuromodulation or reconstructive surgery. This review, the second of two covering the treatment of intractable OAB symptoms in women, will focus on management following the failure of medical therapy. It will principally focus on the role of Botulinum toxin, neuromodulation and reconstructive surgery.

Bladder augmentation and urinary diversion for neurogenic LUTS: current indications

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.

Prospective evaluation of laparoscopic assisted cystectomy and ileal conduit in advanced multiple sclerosis

OBJECTIVE

To assess the morbidity, mortality, and impact on quality of life and renal function after laparoscopic cystectomy and ileal conduit in patients with multiple sclerosis with lower urinary tract symptom refractory to conservative management.

MATERIALS AND METHODS

A prospective study was conducted between February 2004 and December 2010 on 44 consecutive patients with multiple sclerosis who underwent laparoscopic cystectomy and ileal conduit for lower urinary tract symptom. Median Expanded Disability Status Scale score was 8 (6.5-8.5). Mean duration of multiple sclerosis was 19.3 ± 7.9 years. The quality of life was determined using the validated Qualiveen questionnaire preoperatively and at minimum 6 months after the surgery.

RESULTS

No conversion to open surgery was required. Postoperative morbidity rate was 18.2%; minor (Clavien ≤ 2) and major (Clavien ≥ 3) complications occurred in 13.6% and 6.8%, respectively. Mean follow-up was 44.5 ± 20.6 months. Complications noted were asymptomatic ureteroileal stenosis (n = 6) and pyelonephritis (n = 3). Neurological status and Expanded Disability Status Scale score remained stable throughout. Renal function remained unchanged. Limitations, constraints, and specific urinary impact index subscores of the Qualiveen were significantly improved at 6 months time.

CONCLUSION

Laparoscopic cystectomy and ileal conduit for lower urinary tract symptom in advanced multiple sclerosis is a safe procedure with low complications. Neurological status and renal function remain stable and quality of life improves and continues to remain improved during long-term follow-up, suggesting this to be an attractive option in patients with advanced multiple sclerosis with lower urinary tract symptom refractory to conservative treatment.

Neurogenic detrusor overactivity in patients with spinal cord injury: evaluation and management

Lower urinary tract dysfunction can have a significant impact on patients with spinal cord injury. Over the years, many treatment options have become available. This article reviews the assessment and management of neurogenic detrusor overactivity, with a particular focus on articles from the recent literature. Recent guidelines on the subject will be discussed. Management options include antimuscarinics and bladder emptying measures, botulinum toxin A, and neuromodulation in refractory cases and surgery for intractable cases. Recent and relevant publications in these areas will be summarized and discussed.

Carcinoma in the inactive bladder - the dilemma of the forgotten organ

Etiologic factors affecting bladder tumor have been well confirmed and it is widely recognized that carcinogenic substances in urine may play an important role in a pathogenesis. Carcinoma developing in a defunctionalized bladder, although uncommon, does occur. We report a case of a transitional cell carcinoma (TCC) found in a remaining bladder of a male patient and a review of the most relevant literature.

Management of radiation cystitis

Acute radiation cystitis occurs during or soon after radiation treatment. It is usually self-limiting, and is generally managed conservatively. Late radiation cystitis, on the other hand, can develop from 6 months to 20 years after radiation therapy. The main presenting symptom is hematuria, which may vary from mild to severe, life-threatening hemorrhage. Initial management includes intravenous fluid replacement, blood transfusion if indicated and transurethral catheterization with bladder washout and irrigation. Oral or parenteral agents that can be used to control hematuria include conjugated estrogens, pentosan polysulfate or WF10. Cystoscopy with laser fulguration or electrocoagulation of bleeding points is sometimes effective. Injection of botulinum toxin A in the bladder wall may relieve irritative bladder symptoms. Intravesical instillation of aluminum, placental extract, prostaglandins or formalin can also be effective. More-aggressive treatment options include selective embolization or ligation of the internal iliac arteries. Surgical options include urinary diversion by percutaneous nephrostomy or intestinal conduit, with or without cystectomy. Hyperbaric oxygen therapy (HBOT) involves the administration of 100% oxygen at higher than atmospheric pressure. The reported success rate of HBOT for radiation cystitis varies from 60% to 92%. An important multicenter, double-blind, randomized, sham-controlled trial to evaluate the effectiveness of HBOT for refractory radiation cystitis is currently being conducted.

[Laparoscopic cystectomy and transileal ureterostomy for neurogenic vesicosphincteric disorders. Evaluation of morbidity]

OBJECTIVES

To evaluate the morbidity and mortality of laparoscopic cystectomy combined with transileal ureterostomy to treat neurogenic vesicosphincteric disorders.

MATERIAL

Prospective study performed between february 2004 and april 2006 on 26 consecutive patients with a mean age of 55.0 +/- 12.7 years treated by laparoscopic cystectomy for neurogenic vesicosphincteric disorders. The underlying neurological disease was multiple sclerosis (MS) in 20 cases, spinal cord injury in 4 cases and transverse myelitis in 2 cases. The median preoperative ASA score was 3 (range: 2-3).

RESULTS

No open conversion was necessary. One intraoperative complication was observed (vascular injury). No perioperative death was observed. The nasogastric tube was maintained postoperatively for an average of 8.69 +/- 5.9 hours. The mean time to resumption of oral fluids was 1.4 +/- 0.7 days and mean time to resumption of solids was 2.6 +/- 1.0 days. The mean time to resumption of bowel movements was 3.8 +/- 3.2 days. The mean intensive care stay was 3.9 +/- 1.1 days. Two postoperative complications were observed in the same patient (ileus and bronchial congestion). Postoperative narcotic analgesics were necessary in 60% of cases. The mean hospital stay was 10.3 +/- 4.1 days. Two late postoperative complications were observed in the same patient (two episodes of pyelonephritis).

CONCLUSION

Laparoscopic cystectomy has a low morbidity in neurological patients, allowing early return of feeding and a moderate length of hospital stay.
