Nerve-Sparing Radical Cystectomy and Orthotopic Bladder Replacement in Female Patients

ObjectivesOrthotopic diversion, initially performed solely in men, has now become a viable option in women. Approximately 15 yr ago, at several centres, urethra-sparing cystectomy and orthotopic diversion were initiated in women with bladder cancer. Several studies have since addressed both the oncologic and functional outcomes of this procedure. MethodsWe describe our surgical technique of cystectomy and orthotopic urinary diversion in female patients, with an emphasis on how we preserve the neurovascular bundle. Results and ConclusionsAn improved understanding of the anatomic neurovascular and fascial planes related to the rhabdosphincter has facilitated identification of elements needed for orthotopic diversion in female patients. The technique of en bloc anterior exenteration includes the anterior portion of the vagina; however, preservation of the rhabdosphincter and its autonomic nerve supply necessitates specific modifications of the standard operation. The video provides a detailed description of our surgical technique with attention to anatomic details necessary to avoid damage to the proximal urethra and to preserve the autonomic innervation of the rhabdosphincter.

Radical Cystectomy and Orthotopic Bladder Replacement in Females

IntroductionMore than 15 years ago, several centers started to offer urethra-sparing cystectomy and orthotopic urinary diversion for female patients with bladder malignancies. Several studies have been published, outlining both the anatomical and oncological aspects of such an approach. MethodsIn this contribution, the main aspects regarding the surgical technique of cystectomy and orthotopic urinary diversion in female patients, including technical variations which have been derived over the years, are presented. Results and ConclusionThe video shows a detailed description of the surgical technique, and the main steps of the procedure are demonstrated in schematic drawings as well as in animations to facilitate understanding. Emphasis is given on important anatomical and physiological aspects, which have influenced the current surgical steps. Possible sequelae on oncological and functional outcome, which play an important role in the evaluation of this procedure, are also discussed.

Continent cutaneous urinary diversion: long-term follow-up of more than 800 patients with ileocecal reservoirs

We report the clinical outcome of more than 800 patients, who underwent continent cutaneous urinary diversion with an ileocecal reservoir (Mainz-pouch I) in two urological tertiary referral centers at a mean follow-up of 7.6 years. Complications related to the continence mechanism (intussuscepted ileal nipple vs. submucosally embedded in situ appendix) and the antirefluxive uretero-intestinal anastomosis (submucosal tunnel vs. serosa-lined extramural tunnel) were recorded retrospectively. Stomal stenosis was observed in 23.5% of the patients with appendix stoma and in 15.3% of the patients with intussuscepted ileal nipple. The incidence of calculi was 10.8% in reservoirs with intussuscepted ileal nipple and 5.6% in reservoirs with appendix stoma. Eleven patients (eight with appendix, three with ileal nipple) required reoperation because of ischemic degeneration of the continence mechanism. The overall continence rate (day and night) was 92.8%. Anastomotic strictures of the afferent limb occurred in 6.5% of renal units (RUs) with a submucosal tunnel and in 5.0% of RUs with a serosa-lined extramural tunnel. Continent cutaneous urinary diversion with an ileocecal pouch is a highly satisfactory and safe option for patients, in whom orthotopic urinary diversion is impossible or contraindicated.

Erection‐ and Ejaculation‐Preserving Cystectomy With Orthotopic Urinary Diversion: Is It Feasible?

Nerve-sparing techniques to preserve sexual function in men undergoing cystoprostatectomy have been documented by different centers. We evaluated the results of the first 4 erection- and ejaculation-preserving cystectomies performed in our department. The ages of patients ranged between 36 and 43 years. In all cases, patients wished to maintain sexual function. Of the cases, 3 patients had pT1 G3 transitional cell carcinoma (TCC) refractory to treatment and one had pT2a adenocarcinoma of the bladder. Extirpation of the bladder and anterior proximal prostate en bloc with preservation of the vasa deferentia, seminal vesicles, posterior prostate, and neurovascular bundles was performed after pelvic lymphadenectomy. W-ileal neobladder was performed by using 40 cm of ileum. All patients had erections at the third month. Of the cases, 2 patients had antegrade ejaculation. The ejaculate volumes were 0.8 and 1.2 mL in patients with antegrade ejaculation. Patients in the other cases had retrograde ejaculation. All patients were continent day and night. We started clean intermittent catheterization in 1 case because of residual urine. There were no local recurrences. One patient with TCC died because of systemic disease in the postoperative 32nd month. The most important drawback of potent cases in cystectomy decision is erectile dysfunction after radical cystectomy. This drawback causes delay of the operation and sometimes mortality. As was the case in other reports, our limited number of cases in this study demonstrated that erection and ejaculation could be preserved in selected groups of patients.

Persistent and occasional nocturnal enuresis in orthotopic urinary diversion: is there a urodynamic difference?

To establish urodynamic criteria differentiating between men with a radical cystoprostatectomy and ileal neobladder who are persistently enuretic and those who are occasionally enuretic. Fifty enuretic men at least 1 year after a radical cystoprostatectomy and ileal neobladder (hemi-Kock or 'W' neobladders) were divided into two groups according to the persistence of their complaint; 17 men were persistently enuretic (nightly) and 33 were occasionally enuretic (<3 episodes/week). Both groups were compared with 50 fully continent men with similar reservoirs. Uroflowmetry, enterocystometry and urethral pressure profilometry were carried out according to International Continence Society standards and terminology. Both enuretic groups had significantly higher residual urine volumes, pressure at mid-capacity and at maximum enterocystometric capacity, amplitude of uninhibited contractions, and lower compliance than continent men. Men with occasional enuresis also had a significantly higher frequency and duration of uninhibited contractions than continent men. Men with persistent enuresis had significantly lower average and maximum urinary flow rates than continent men, and significantly lower functional urethral length and maximum urethral pressure. Uroflowmetric and urethral pressure differences were dissimilar between men with occasional enuresis and controls. Enuretic men had significantly higher residual urine volumes and enterocystometric pressure variables than continent men. Men with persistent enuresis had significantly lower flow rates and less urethral resistance. Pharmacological inhibition of reservoir contraction and/or management of residual urine by clean intermittent catheterization before sleep might cure occasional enuresis.

Preservation of the anterior vaginal wall during female radical cystectomy with orthotopic urinary diversion: technique and results.

Orthotopic urinary reconstruction has been shown to be a viable option in women undergoing radical cystectomy. However, due to anatomical differences and technical considerations orthotopic diversion has been performed in a relatively small number of patients. We examined our technique of vaginal wall preservation during female radical cystectomy and orthotopic neobladder construction. We reviewed the records of all patients who underwent radical cystectomy between January 1994 and December 2001. Of these 542 patients we identified 94 females, of whom 25 (27%) underwent orthotopic neobladder substitution. We reviewed perioperative major and minor complications, postoperative care, followup and pathological results. Overall 21 of the 25 patients (84%) underwent anterior vaginal wall sparing. Five patients (24%) had minor complications, there were no major perioperative complications and no patients required transfusion. Median estimated blood loss in this group was 575 ml. (range 200 to 1,250). A single neobladder-vaginal fistula developed in a patient early in our series in whom the anterior vaginal wall was incised and repaired during dissection. Of the 21 patients 15 (72%) were continent. Pathological specimens revealed a negative posterior bladder wall and urethral margins in all cases. At a median followup of 12 months 1 patient had local recurrence. Anterior vaginal wall preservation in female radical cystectomy with orthotopic neobladder substitution is technically feasible, maintains vaginal length and support, has an acceptable complication rate and can achieve negative margins. Prospective evaluation is needed to assess the long-term impact on functional outcomes and cancer control.

Prostatic Capsule‐ and Nerve‐sparing Cystectomy in Organ‐confined Bladder Cancer: Preliminary Results

We present a novel radical cystectomy technique that allows bladder cancer control while maintaining urinary continence and reducing the risk of erectile dysfunction by sparing the prostatic capsule and the neurovascular bundles. Between September 1997 and December 2002, 85 men were candidates for cystectomy; 32 were selected for a prostatic capsule- and seminal-sparing cystectomy with orthotopic urinary diversion. All patients had clinical organ-confined bladder cancer (cT1 to cT3a). One patient died of unrelated causes. Of the remaining 31 patients, two with pT4, N+ disease underwent three cycles of adjuvant chemotherapy and are free of disease at 10 and 12 months postoperatively. Twenty-nine patients with organ-confined bladder cancer are free of disease after a mean follow-up of 32 months. At 24 months, 98% of the patients are completely continent during the day and 83% during the nighttime hours. In addition, 80% of the patients are able to complete sexual intercourse without auxiliary measures at a mean of 24 months postoperatively. Prostatic capsule- and nerve-sparing cystectomy permits en bloc removal of the bladder, of the adenomatous prostatic tissue, and of the seminal vesicles, thereby achieving local cancer control and preserving erectile function and urinary continence.

Short- and long-term issues regarding urethral management in male radical-cystectomy patients

Radical cystectomy remains the gold-standard therapy for invasive bladder cancer. Management of the urethra before, during, and after cystectomy, however, is still not standardized. Herein, the rationale for different management algorithms is given. The literature remains inconsistent regarding the best diagnostic and therapeutic management of the urethra before and during cystectomy as well as afterwards. The risk of urethral recurrence may in fact be lower after orthotopic urinary diversion, but the evidence for this and other recommendations comes from retrospective series. Urethral recurrence, although uncommon, continues to have a poor prognosis, and the optimal follow-up regimen is unclear. The importance of lifelong follow-up is unquestioned. Risk factors for urethral involvement/recurrence can be determined before, during, and after radical cystectomy. The best way to diagnose and predict who will recur, however, is still unknown, as is the optimal follow-up regimen and treatment for the remnant urethra. The type of urinary diversion may in fact influence disease recurrence, as it also affects possible therapy for patients with recurrence.

Implantation des artifiziellen Sphinktersystems AMS 800 bei der Frau über einen paraurethralen Zugang

The procedure described demonstrates the feasibility of reliable implantation of an artificial sphincter system in female patients via a paraurethral access between the urethral orifice and the clitoris following radical cystectomy with continent, orthotopic urinary diversion and postoperatively developed urinary stress-incontinence. The technique presented avoids the more invasive transperitoneal or transvaginal approaches which jeopardize the neobladder-neck and increase the risk for infections or fistulas.

Radical cystectomy in the elderly

The authors report their experience with radical cystectomy for transitional cell carcinoma (TCC) of the bladder comparing clinical outcomes, including complication rates, among older patients versus younger patients in a high-volume center specializing in the treatment of patients with advanced carcinoma of the urinary bladder. A retrospective review was undertaken of 1054 patients who underwent radical cystectomy for bladder TCC from 1971 through 1997. Four age groups were compared; < 60 years at the time of cystectomy (n = 309 patients), age 60-69 years (n = 381 patients), age 70-79 years (n = 314 patients), and age > or = 80 years (n = 50 patients). The median length of hospital stay in patients ages < 60 years, 60-69 years, 70-79 years, and > or = 80 years was 10 days, 10 days, 11 days, and 11 days, respectively (P < 0.001). The corresponding rates of overall early complications were 24%, 25%, 37%, and 30%, respectively (P = 0.002); whereas the corresponding late complication rates were 36%, 30%, 22%, and 14%, respectively (P < 0.001). The rate of early diversion-related complications did not differ significantly (11%, 8%, 12%, and 6%, respectively; P = 0.14). The operative mortality rates were 1%, 3%, 4%, and 0%, respectively (P = 0.14). There was no difference with respect to early complications, early diversion-related complications, late complications, or operative mortality comparing patients age > 70 years who underwent ileal conduit versus orthotopic urinary diversion (P = 0.20, P = 0.61, P = 0.53, and P = 0.78, respectively). Elderly patients who underwent cystectomy for TCC had similar mortality and early diversion-related complication rates. Carefully selected elderly patients safely can be offered an orthotopic urinary diversion. Chronological age, per se, is not a contraindication for radical cystectomy in the setting of invasive bladder carcinoma.

Urethral recurrence in patients following orthotopic urinary diversion: Hassan JM, Cookson MS, Smith JA Jr, Chasubng SS, Department of Urologic Surgery, Vanderbilt University Medical Center, Nashville, TN

We present our experience with urethral recurrence of transitional cell carcinoma following cystectomy and orthotopic urinary diversion in a contemporary series. 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. 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). 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.

Prostatic capsule- and seminal-sparing cystectomy for bladder carcinoma: initial results for selected patients: Botto H, Sebe P, Molinie V, Herve JM, Yonneau L, Lebret T, Department of Urology, Hopital Foch, Suresnes, France

To evaluate the oncological outcome and functional results of prostate-sparing cystectomy (PSC), proposed for treating bladder cancer, used since 1999 in our institution in an attempt to preserve male sexuality and to increase continence after cystectomy. Between January 1999 and December 2001, 111 men were candidates for cystectomy; 42 were selected for a prostatic capsule- and seminal-sparing cystectomy with orthotopic urinary diversion. All patients had clinically organ-confined tumours (clinical stage </= T2, N0M0). The first stage of the procedure was a transurethral resection of the prostate to exclude the involvement of transitional cell carcinoma (TCC) in the prostate. Eight patients were excluded from PSC because they had TCC (seven) or prostate adenocarcinoma (one). The mean age of the remaining 34 patients was 61 years and all underwent PSC. After a mean follow-up of 26 months, seven patients (21%) had a recurrence; one developed a local recurrence, there were widespread metastases in six (18%), and five had histologically confirmed organ-confined tumour (T1-2N0M0). Rates for daytime and night-time continence were 90% and 85%, and in 29 patients potency was unchanged. These early results suggest that PSC is not equivalent to radical cystoprostatectomy for bladder cancer control, despite marked improvements in the functional results. Moreover, in carefully selected patients this approach appears to dramatically increase an unusually high metastasis rate. Therefore, the indications for PSC should be either clearly well defined or abandoned in these patients.

URETHRAL TUMOR RECURRENCE FOLLOWING CYSTECTOMY AND URINARY DIVERSION: CLINICAL AND PATHOLOGICAL CHARACTERISTICS IN 768 MALE PATIENTS

We evaluated the incidence and risks of urethral recurrence following radical cystectomy and urinary diversion in men with transitional cell carcinoma of the bladder. Clinical and pathological results were evaluated in 768 consecutive male patients undergoing radical cystectomy with intent to cure for bladder cancer with a median followup 13 years, including 397 (51%) who underwent orthotopic urinary diversion with a median followup of 10 years and 371 (49%) who underwent cutaneous urinary diversion with a median followup of 19 years. Demographically and clinically these 2 groups were well matched with the only exception being longer median followup in the cutaneous group (p <0.001). Urethral recurrence was analyzed by univariate and multivariable analysis according to carcinoma in situ, tumor multifocality, pathological characteristics (tumor grade, stage and subgroup), the presence and extent of prostate tumor involvement (superficial vs stromal invasion) and the form of urinary diversion (cutaneous vs orthotopic). A total of 45 patients (6%) had urethral recurrence at a median of 2 years (range 0.2 to 13.6), including 16 (4%) with an orthotopic and 29 (8%) with a cutaneous form of urinary diversion. Carcinoma in situ and tumor multifocality were not significantly associated with an increased risk of urethral recurrence (p = 0.07 and 0.06, respectively). The presence of any (superficial and/or stromal invasion) prostatic tumor involvement was identified in 129 patients (17%). Prostate tumor involvement was associated with a significantly increased risk of urethral recurrence (p = 0.01). The estimated 5-year chance of urethral recurrence was 5% without any prostate involvement, increasing to 12% and 18% with superficial and invasive prostate involvement, respectively. Patients undergoing orthotopic diversion demonstrated a significantly lower risk of urethral recurrence compared with those undergoing cutaneous urinary diversion (p = 0.02). Patients without any prostate tumor involvement and orthotopic diversion (lowest risk group) demonstrated an estimated 4% year chance of urethral recurrence compared with a 24% chance in those with invasive prostate involvement undergoing cutaneous diversion (highest risk group). On multivariate analysis any prostate involvement (superficial and/or invasive) and urinary diversion form remained independent and significant predictors of urethral recurrence (p = 0.035 and 0.01, respectively). At long-term followup urethral tumor recurrence occurs in approximately 7% of men following cystectomy for bladder transitional cell carcinoma. Involvement of the prostate with tumor and the form of urinary diversion were significant and independent risk factors for urethral tumor recurrence. Patients undergoing orthotopic diversion have a lower incidence of urethral recurrence compared with those undergoing cutaneous diversion. Although prostate tumor involvement is a risk factor for urethral recurrence, it should not preclude orthotopic diversion, provided that intraoperative frozen section analysis of the urethral margin is without evidence of tumor.

What is the ratio of urethral recurrence risk after radical cystoprostatectomy for bladder cancer?

There is always a risk of urethral recurrence after radical cystoprostatectomy in patients with bladder transitional cell cancer. Taking these risk factors of urethral recurrence into account, orthotopic neobladders or urinary diversions without using the urethra are performed. But urethral tumour recurrence occurs much less than the expected. We assessed the etiological factors that affect the urethral recurrence in orthotopic and nonorthotopic urinary diversion cases. Sixty-four patients with bladder cancer who underwent radical cystoprostatectomy and urinary diversion between 1994 and 2002 were included this study. Conventional risk factors effecting the selection of operation type and urethral recurrence were evaluated in these patients. Cystoscopy and biopsy were done and pathologic specimen was obtained preoperatively, and cystoscopy and urethral washout cytology were done postoperatively. Routine bladder biopsies were done in uncertain cases at follow-up. Risk factors increasing the urethral recurrence are as follows: papillary and multiple tumours, tumour invading bladder neck and trigone, extensive CIS, prostatic stromal and urethral invasion, positive surgical margin and history of upper urinary tract tumour. In 31 patients having one or more of these criteria, continent nonorthotopic urinary diversion was performed, but 33 patients without these risk factors underwent orthotopic urinary diversion. Simultaneous urethrectomy was not done in any of these patients. Among the patients who underwent radical cystoprostatectomy, none was with positive surgical margin in the distal end of the prostatic urethra. In preoperative cystoscopy, tumoural mass was seen near to collum in eight patients and in the prostatic urethra in three patients. Histopathological examination of cystoprostatectomy specimen displayed transient epithelial cell carcinoma of prostatic urethra in three patients, transient epithelial cell metaplasia inside the prostate in five patients and invasion to the urothelium of bladder neck in three patients. There were not any transient epithelial cell cancer metastases in prostatic stroma in any of these patients. One patient underwent urethrectomy, since atypical cells were observed in postradical prostatectomy urethral washout cytology but there was no tumour found in pathological examination of the specimen. Therefore, urethral tumour recurrence did not occur after 25 months follow up. These findings suggest that some of the conventional risk factors of urethral recurrence were exaggerated. We may also conclude that there is no need for prophylactic urethrectomy unless there is urethral cancer or cancer in the surgical margin. But if utilization of urethra is planned, evaluation of prostatic stroma by TUR biopsies and urethral anastomose margin by frozen section during the operation is necessary.

Prostatic capsule‐ and seminal‐sparing cystectomy for bladder carcinoma: initial results for selected patients

To evaluate the oncological outcome and functional results of prostate-sparing cystectomy (PSC), proposed for treating bladder cancer, used since 1999 in our institution in an attempt to preserve male sexuality and to increase continence after cystectomy. Between January 1999 and December 2001, 111 men were candidates for cystectomy; 42 were selected for a prostatic capsule- and seminal-sparing cystectomy with orthotopic urinary diversion. All patients had clinically organ-confined tumours (clinical stage </= T2, N0M0). The first stage of the procedure was a transurethral resection of the prostate to exclude the involvement of transitional cell carcinoma (TCC) in the prostate.

These early results suggest that PSC is not equivalent to radical cystoprostatectomy for bladder cancer control, despite marked improvements in the functional results. Moreover, in carefully selected patients this approach appears to dramatically increase an unusually high metastasis rate. Therefore, the indications for PSC should be either clearly well defined or abandoned in these patients.
