Ileal conduit in era of systemic chemotherapy

The records of 62 patients with invasive transitional cell carcinoma of the bladder whose planned treatment was radical cystectomy with ileal conduit urinary diversion and postoperative systemic chemotherapy were reviewed. Seven of the patients received radical cystectomy but not postoperative chemotherapy as planned, 3 of them (5%) for reasons directly related to complications from the urinary diversion. Fifty-five patients received the planned postoperative chemotherapy. Complications during chemotherapy that were related to the ileal conduit were urinary tract infection in 37 percent and stenosis at the ureteroileal anastomosis requiring percutaneous nephrostomy in 3.6 percent. Chemotherapy was not discontinued in any patient, however, because of complications specifically related to the urinary diversion. We conclude that the ileal conduit is well tolerated by patients who require systemic chemotherapy and is, today, the simplest, safest, and best diversion method when systemic chemotherapy is to follow radical cystoprostatectomy.     

Improvement of ureteroileal anastomosis in orthotopic ileal neobladder with modified le duc procedure: short submucosal tunnel technique

PURPOSE: A modified Le Duc procedure with a short submucosal tunnel was applied for ureteroileal implantation in ileal orthotopic neobladder and bladder augmentation with the ileum. We assessed the rate of stenosis and ureteral reflux at the ureteroileal anastomosis after this procedure. MATERIALS AND METHODS: Two women and 22 men underwent radical cystectomy and creation of a Hautmann ileal neobladder for invasive bladder cancer. Another woman underwent ileal bladder augmentation with bilateral ureteral reimplantation into the ileal segment. Ureteroileal anastomosis was performed using the modified Le Duc technique in 48 renoureteral units. Followup in all patients included retrograde cystography done before discharge home and excretory urography, renal ultrasonography or abdominal computerized tomography every 4 to 6 months. Followup was 11 to 39 months in 23 of the 25 cases. RESULTS: Retrograde cystography before discharge home revealed no urinary reflux in any reimplanted ureter. There was no ureteral stenosis or reflux in 20 male and 3 female patients (44 renoureteral units) who voided successfully without catheterization. A unilateral ureteral stricture at the ureteroileal anastomotic site in 1 man who voided successfully was treated with endoscopic surgery. Bilateral slight upper urinary tract dilatation caused by ureteral reflux was present in another man who did not void successfully. CONCLUSIONS: The modified Le Duc technique is simple and safe for forming an ureteroileal anastomosis in ileal orthotopic neobladder creation. It appears to have a low ureteral stenosis and reflux complication rate in patients who successfully void postoperatively.     

Kidney stone formed around refluxed surgical staple and removed by transureteral endoscopic manipulation.

We present a case of a kidney stone that developed around a surgical staple which refluxed up to the kidney following a Bricker urinary diversion and bilateral ureteroileal anastomosis. A GIA stapler had been utilized to construct the ileal conduit. The stone was retrieved by means of flexible ureterorenoscopy through the ileal conduit. To our knowledge, this is the first report of such a complication following construction of an ileal conduit with a stapling device.     

膀胱全切原位回肠新膀胱术后输尿管肠吻合口良性狭窄的处理

目的：探讨膀胱全切原位回肠新膀胱术后输尿管肠吻合口良性狭窄的处理方法。方法：我科自2003年1月～2012年6月采用膀胱全切原位回肠新膀胱术治疗395例膀胱癌患者。术后发生输尿管肠吻合口良性狭窄10例,采用输尿管镜扩张、内镜下逆行／经皮穿刺顺行球囊扩张、内镜下狭窄段内切开、开放输尿管膀胱再植术,并留置双J管3～6个月。结果：本组10例中,1例（1处）因导丝不能通过狭窄段而改行开放手术,术后随访36个月,肾积水明显改善。其余9例（11处）采用腔内技术处理,其中3例（4处）采用输尿管镜扩张,2例（3处）采用内镜下狭窄段内切开,4例（4处）采用内镜下逆行／经皮穿刺顺行球囊扩张。术后随访9～72个月（中位25个月）。5例（7处）肾积水明显改善,2例（2处）肾积水长期随访无加重,2例（2处,狭窄段长分别为1．2cm、1．5cm）再发狭窄,遂采用开放手术,分别随访16及24个月,肾积水改善。结论：腔内技术操作简单,创伤小,可作为输尿管肠吻合口良性狭窄的首选治疗方案。开放手术仍然是治疗输尿管肠吻合口狭窄的金标准。对于狭窄段〉1cm的患者,应首先考虑开放手术。     

Laparoscopic radical cystectomy with urinary diversion: completely intracorporeal technique

Laparoscopic radical cystectomy with urinary diversion performed using intracorporeal techniques exclusively is a new development in the growing field of minimally invasive urology. This report details step by step the completely intracorporeal laparoscopic technique of cystectomy, bilateral pelvic lymphadenectomy, and urinary diversion with creation of an ileal conduit or neobladder, including the isolation of ileum, restoration of bowel continuity, retroperitoneal transfer of the left ureter to the right side, bilateral stented ureteroileal anastomoses, and urethroileal anastomosis in case of orthotopic diversion. Although at present, this is still a technique in development at high-volume medical centers, it holds promise as a minimally invasive yet appropriately radical form of treatment for patients with muscle-invasive bladder cancer. Definition of its true role awaits greater experience and long-term comparisons of the outcomes with those of traditional open surgery.

Vescica Ileale Padovana: a technique for total bladder replacement

A new technique for detubularized and originally reshaped ileal total bladder replacement following radical cystectomy for bladder cancer is described and named 'Vescica Ileale Padovana'. 16 patients have been clinically, radiologically and urodynamically evaluated with a follow-up ranging from 4 to 18 months (mean 10 months). The complication rate was low: 1 ureteroileal stenosis; 2 urethroileal strictures. Daytime continence was perfect in 87% (14 of 16 patients). Nighttime continence was perfect (dry sleep for 6-7 h) in 81% (13 of 16 patients). The reservoir features were: high capacity (400-650 ml); low pressure (mean pressure at capacity 17 cm H2O no pressure waves in 50% of patients 30-50 cm H2O wide pressure waves with 250-ml threshold volume in 50%); absence of reflux; complete voiding by abdominal straining, and perineal relaxation.     

Extraperitonealization of ileal conduit reduces parastomal hernia after cystectomy and ileal conduit diversion

ObjectiveParastomal hernia (PSH) is a common complication of ileal conduit diversion after radical cystectomy. Novel surgical techniques for preventing PSH formation are needed. We aimed to evaluate surgical technique of extraperitonealizing the ileal conduit (modified ileal conduit) for preventing PSH.MethodsA retrospective analysis of 375 consecutive patients who underwent ileal conduit after cystectomy at the Sun Yat-sen University Cancer Center between January 1, 2000 and June 31, 2019 was conducted. 214 patients had modified ileal conduit diversion and 161 patients conventional ileal conduit (Bricker) diversion. The demographic and clinicopathologic characteristics of patients in the 2 groups were compared using the t test and Chi square test. Univariable and multivariable Cox regression analyses were used to predict the risk of PSH formation.ResultsThe 2 groups were comparable in regard to all demographic and clinicopathologic variables. The incidence of PSH diagnosed by CT scan was 7.5% in the modified group and 21.1% in the conventional group (P < 0.001). High BMI and history of prior abdominal surgery was identified by univariable analysis as risk factors of PSH formation. Multivariable analyses revealed that technique of extraperitonealizing ileal conduit significantly reduced incidence of PSH in patients with or without risk factors of PSH formation (OR = 0.29, 95% CI 0.16–0.54, P < 0.001).ConclusionsTechnique of extraperitonealizing ileal conduit appeared to be effective in reducing PSH formation after ileal conduit diversion.

Is adjuvant chemotherapy for bladder cancer safer in patients with an ileal conduit than a neobladder?

OBJECTIVE: To assess the safety of adjuvant chemotherapy in patients with neobladder reconstruction in comparison to ileal conduit, as radical cystectomy and urinary diversion is an effective curative surgical treatment for muscle-invasive and high-risk superficial bladder cancer, and adjuvant chemotherapy is usually considered for patients with clinical stage > T2 and nodal metastasis. PATIENTS AND METHODS: We analysed retrospectively patients who had had a radical cystectomy and urinary diversion between 1992 and 2004. Patients with high-risk disease who had adjuvant chemotherapy were identified and stratified based on the type of urinary diversion (ileal conduit or neobladder). The chemotherapy regimen, complications from the adjuvant chemotherapy and other relevant data were analysed. RESULTS: Overall, 343 patients had radical cystectomy, 40 had adjuvant chemotherapy; 25 had an ileal conduit and 15 had a neobladder. Patient characteristics including age, stage and follow-up were similar. In all, 55% of patients had grade 1 toxicity, 23% grade 2, 18% grade 3, and 13% grade 4. No patients had serious organ toxicity and none died. There were no significant differences in the toxicity among the two groups. CONCLUSIONS: Adjuvant chemotherapy appears to be safe in patients with a neobladder and equally safe in patients with an ileal conduit. Hence neobladder reconstruction should not be denied to patients with bladder cancer who are at high risk of recurrence and who might require adjuvant chemotherapy.     

Case report: Laparoscopy-assisted urinary undiversion: transforming an ileal conduit into an orthotopic continent neobladder

PURPOSE: To describe the technique of laparoscopy-assisted undiversion of an ileal conduit into a continent orthotopic ileal neobladder performed on a patient with a previous radical cystoprostatectomy and ileal conduit. CASE REPORT: A 57-year-old man presented with a prolapsed stoma and a history of a right radical nephroureterectomy for grade 3 ureteral transitional-cell carcinoma and a radical cystoprostatectomy and ileal conduit urinary diversion for in-situ bladder carcinoma, performed 12 and 8 years ago, respectively. After the ileal stoma was resected, five trocars were placed transperitoneally. Partial resection of the distal ileal conduit was performed, leaving in place the proximal segment with its left ureteroileal anastomosis. Flexible urethroscopy revealed a contracting external sphincter, and random urethral frozen-section biopsies ruled out tumor. A 45-cm segment of ileum was isolated and exteriorized through the stoma site, and an ileal neobladder was created extracorporeally, suturing the proximal ileal-conduit segment, with its ureteroileal anastomosis, to it. The ileal neobladder was reintroduced into the abdomen and anastomosed laparoscopically to the urethral stump with six 2-0 polyglactin sutures. The total operative time was 7 hours with a blood loss of 100 mL. There were no intraoperative complications. The hospital stay was 7 days. At a follow-up of 24 months, the patient had total daytime continence and normal renal function, and intravenous urography revealed an unobstructed urinary tract. CONCLUSION: Laparoscopy-assisted ileal-conduit undiversion into an orthotopic ileal neobladder is technically feasible. It can be considered an alternative to open surgery for patients who have undergone urinary diversion.     

Transitional cell carcinoma in the ileal conduit following radical cystectomy and nephroureterectomy.

We report a case of transitional cell carcinomas (TCCs) at the terminal of ileal conduit and right ureteroileal junction after cystectomy and left nephroureterectomy. When upper urinary tract tumor occurs after cystectomy with ileal conduit, it is necessary to beware of the recurrence of TCC in the ileal conduit.     

Urinary fistula into ureteral stump after ileal conduit diversion

Despite ileal conduit diversion for urinary incontinence, an adolescent male with meningomyelocele continued to void per urethram postoperatively. Urologic investigation disclosed spontaneous fistulization from a ureteroileal anastomosis to a ligated ureteral stump, with resultant urinary drainage to the bladder. This unusual complication of ileal conduit diversion has not been reported previously. More attention should be directed to securing a watertight ureteroileal anastomosis. A careful single layer anastomosis is recommended to minimize urinary leakage without increasing the risks of stenosis and obstruction.
