THE T POUCH: AN ORTHOTOPIC ILEAL NEOBLADDER INCORPORATING A SEROSAL LINED ILEAL ANTIREFLUX TECHNIQUE

Purpose

At our institution the Kock ileal neobladder has been the primary form of urinary diversion after cystectomy. The few associated complications are primarily related to the intussuscepted antireflux afferent limb, including stones, stenosis and extussusception of the afferent nipple. We present a novel orthotopic ileal neobladder, the T pouch, with an innovative antireflux technique designed to prevent complications of the intussuscepted afferent nipple.

Material and Methods

From November 1996 through August 1997, 40 patients an average of 67 years old underwent construction of an orthotopic ileal neobladder (T pouch). Mean followup is 10.5 months (range 8 to 14). The T pouch incorporates an antireflux mechanism using a serosal lined ileal tunnel technique. Urinary reflux is prevented without ileal intussusception and with complete preservation of the blood supply to the afferent ileal segment. Followup in all cases includes clinical and functional results, and radiographic evaluation of the urinary reservoir and upper urinary tracts.

Results

One perioperative death (2.5%) and 5 early complications (12.5%) were unrelated to urinary diversion. There have been no late complications. All T pouch reservoirs had excellent capacity without evidence of urinary reflux. The upper urinary tracts remain unchanged or improved in all patients.

Conclusions

The T pouch is an orthotopic ileal neobladder that incorporates an effective, innovative antireflux mechanism created by a serosal lined ileal tunnel. Early clinical and functional results of this type of urinary diversion have been excellent. Furthermore, we suspect that this antireflux technique may eliminate the complications associated with an intussuscepted afferent nipple and maintain an effective antireflux mechanism.     

The serous-lined tunnel principle for urinary reconstruction: a more rational method.

OBJECTIVE: To examine the feasibility of using the serous-lined-tunnel principle for orthotopic neobladder, continent cutaneous diversion and ureteric replacement by an intestinal segment. Patients and methods We created: (i) an orthotopic ileal neobladder using the serous-lined technique for antirefluxing ureteric implantation in 16 patients; (ii) a continent ileal pouch, adopting the principle for continent-valve construction and for ureteric implantation, in 10 patients (another patient with a failed continent valve underwent revision using an adaptation of this principle; and (iii) by applying the same principle an ileal ureter with a proximal antirefluxing mechanism was constructed in two patients (with lower ureteric cancer), and total replacement of the ureter by a tubular segment of the colon in association with a continent transverse colon pouch in one irradiated patient. RESULTS: In all, 52 ureters implanted into ileal neobladders or continent pouches functioned well, with neither obstruction nor reflux; 11 continent valves functioned well with no incontinence. Two patients with ileal ureters showed no ileo-ureteric reflux and had less hydronephrosis than before surgery. The tubularized ureter provided a unidirectional flow into the pouch. Conclusion Ureteric reimplantation and continent valve formation achieved by adopting the serous-lined tunnel principle provided satisfactory results. The versatility of the principle is apparent in the present experience and the creative application of the serous-lined tunnel principle should be possible in urinary reconstruction.     

Laparoscopic radical cystectomy and continent orthotopic ileal neobladder performed completely intracorporeally: the initial experience

PURPOSE: We introduce the operative technique of laparoscopic radical cystectomy and orthotopic ileal neobladder with a Studer limb performed completely intracorporeally. MATERIALS AND METHODS: The procedure was performed in 1 man and 1 woman. Using a 6 port transperitoneal approach, radical cystectomy in the female patient and radical cystoprostatectomy in the male patient were completed laparoscopically with the urethral sphincter preserved. Bilateral pelvic lymphadenectomy was done. A 65 cm. segment of ileum 15 cm. from the ileocecal junction was isolated, and ileo-ileal continuity was restored using Endo-GIA staplers (U.S. Surgical, Norwalk, Connecticut). The distal 45 cm. of the isolated ileal segment were detubularized, maintaining the proximal 10 cm. segment intact as an isoperistaltic Studer limb. A globular shaped ileal neobladder was constructed and anastomosed to the urethra. Bilateral stented ureteroileal anastomoses were individually performed to the Studer limb. All suturing was done exclusively using free-hand laparoscopic techniques and the entire procedure was completed intracorporeally. An additional case is described of Indiana pouch continent diversion in which the pouch was constructed extracorporeally. RESULTS: Total operative time for laparoscopic radical cystectomy and orthotopic neobladder was 8.5 and 10.5 hours, respectively, with a blood loss ranging from 200 to 400 cc. Hospital stay was 5 to 12 days and surgical margins of the bladder specimen were negative in each case. Both patients with orthotopic neobladder had complete daytime continence. Postoperative renal function was normal and excretory urography revealed unobstructed upper tracts. During followup ranging from 5 to 19 months 1 patient died of metastatic disease, while the other 2 are doing well without local or systematic progression. CONCLUSIONS: Laproscopic radical cystectomy and orthotopic ileal neobladder performed completely intracorporeally are feasible.

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.     

Orthotopic ileal neobladder in male patients: Functional outcomes of 66 cases

BACKGROUND: Orthotopic urinary diversion has become the preferred form of bladder reconstruction after cystectomy. We report on our experience with 66 male patients undergoing this procedure from November 1990 to February 1998. METHODS: A neobladder was constructed using an ileal segment with a Hautmann type bladder. Complications were assessed and subdivided into early and late types. Voiding function was evaluated in terms of voiding pattern and continence. Median follow up was 19.5 (range 3.5-87.7) months. RESULTS: There was one (1.5%) perioperative death. The most frequent pouch-related and unrelated early complications were persistent urine leak (7.6%) and prolonged ileus (16.7%), respectively, the majority of cases of which were managed conservatively. Analysis of late complications revealed 6.2% ureteroileal stenosis and 1.5% urethrointestinal stenosis rates, but no case of bladder stone formation. Of the 61 patients in whom voiding function was evaluable, 95.1% achieved excellent daytime continence, while only 67.2% had night-time continence. With regard to posture at voiding, 23 (37.7%) voided in a sitting position. Three of the patients (4.9%) were unable to void and required regular intermittent catheterization. CONCLUSIONS: An orthotopic neobladder can be constructed with acceptable morbidity and excellent functional results. We believe that orthotopic urinary diversion offers an attractive alternative to a bladder substitute when cystectomy is required.     

Surgical complications of urinary diversion

We comprehensively reviewed the published literature on urinary diversion, specifically examining the surgical complications associated with conduit, continent cutaneous diversion and orthotopic urinary diversion. Appropriate patient selection and adherence to proper surgical technique are of paramount importance in preventing surgical complications of urinary diversion. Complications can be broadly divided into those related to bowel, conduit or reservoir, stoma and ureterointestinal anastomosis. Each type of urinary diversion has unique characteristics predisposing to certain surgical complications as well as similarities related to intestinal surgery. With conduit urinary diversions, problems related to the stoma such as stomal stenosis and parastomal hernia present not uncommonly. With continent cutaneous diversion, complications include difficulties with catheterizing of the efferent limb, formation of pouch stones and urinary leakage. With orthotopic neobladder formation, voiding dysfunction manifesting as incontinence or hypercontinence may present unique challenges in patient management. Increased surgical experience and technical refinements have led to decreasing surgical complication rates for all types of diversion in contemporary series.     

Hammock nonrefluxing ureteroileal anastomosis]

Hammock nonrefluxing ureteroileal anastomosis was performed on 14 patients who had urinary tract reconstruction using ileal conduit (4), Kock pouch (3), modified Kock pouch with plicated efferent limb (1) and ileal neobladder (6). Radiographic examinations showed ureteral reflux of contrast medium in one patient (7.1%), ureteral stenosis in one patient (7.1%) and no urine leakage. Three patients had pyelonephritis (21.4%) and no one had any upper tract urolithiasis. This technique provides a simple and reliable antireflux mechanism into ileal segments without nonabsorbable material.     

Urinary undiversion; Bricker to Studer. With regard of two cases

We present two cases of urinary undiversion from an ileal loop (Bricker) to an orthotopic neobladder. Due to miss adaptation to the stoma, two patients demanded reconversion to a continent urinary diversion. We proceed to change their urinary diversion to an ileal neobladder (Studer), one by open surgery and the other by laparoscopic surgery. In both cases immediate postoperative went uneventful. Both patients are continent, satisfied with their new situation, and without metabolic complications. Urinary undiversion from an ileal conduit to an orthotopic neobladder is technically feasible by open or laparoscopic surgery. It is a valid alternative for patients with complications due to their urinary diversion or miss adaptation to the cutaneous stoma.     

Retrograde ureteroscopy in patients with orthotopic ileal neobladder urinary diversion

PURPOSE: We assess the feasibility, technique, complications and clinical outcomes of retrograde ureteroscopy in patients with orthotopic ileal neobladder. MATERIALS AND METHODS: We retrospectively reviewed our ureteroscopy experience to identify procedures performed in patients who had previously undergone cystectomy with orthotopic ileal neobladder urinary diversion. These procedures were reviewed and data collected regarding patient characteristics, indication for endoscopic evaluation, surgical technique, findings, complications and followup. RESULTS: Eight patients with neobladder diversion were taken for 9 sessions in the cystoscopy suite for attempted retrograde ureteroscopy on 13 renal units. The indication for ureteroscopy was an upper tract filling defect, positive cytology or calculi. The ureter and renal pelvis were successfully accessed and visualized in 10 of 13 renal units. The cause of failure in the 3 unsuccessful procedures was inability to access the ureteral orifice. Mean operative time +/- SD was 78 +/- 34 minutes. Urothelial abnormalities were identified in 4 patients, extrinsic compression in 2 and stones in 3. In 1 patient postoperative hematuria developed, which spontaneously resolved. Fluoroscopy was essential to identify the afferent limb of the reservoir, and a directional guide wire was helpful in engaging the ureteral orifice. CONCLUSIONS: Ureteroscopic evaluation and treatment of upper tract abnormalities are feasible and practical in most patients with orthotopic neobladder urinary diversion. Identification of the ureteral orifice is challenging but can be accomplished with a combination of endoscopic and fluoroscopic techniques. This procedure avoids the morbidity of percutaneous access, and complications are minimal.

The Kock Ileal Neobladder: Updated Experience in 295 Male Patients

Purpose

Since 1986 orthotopic lower urinary tract reconstruction using the Kock ileal neobladder has been our diversion of choice in patients undergoing cystectomy. We report on the first 295 male patients undergoing this procedure from May 1986 through December 1993.

Materials and Methods

Complications were assessed, tabulated, subdivided into early (3 months or less postoperatively) and late types, and further categorized with respect to relationship to neobladder construction. Continence was individually evaluated via a detailed patient questionnaire.

Results

The pouch related early and late complication rates were 7.2 and 11.6 percent, respectively, and pouch related abdominal reoperation rates were 0.0 and 1.4 percent, respectively. Analysis of late pouch related complications revealed 4.1 percent stone formation and 2.4 percent afferent nipple stenosis rates, and only 1 case (0.3 percent) of ileal urethral anastomotic stricture. Of the patients 87 and 86 percent reported good or satisfactory daytime and nighttime continence, respectively. With regard to age, while overall continence was similar, a significantly greater percentage of patients younger than 70 years experience good daytime and nighttime continence relative to the older counterparts. Of the patients 5 percent perform regular intermittent catheterization and 2.7 percent required an artificial urinary sphincter due to unacceptable continence.

Conclusions

The Kock orthotopic ileal neobladder can be constructed with minimal morbidity and extraordinary functional results. We strongly advocate its use when possible.     

Lower urinary tract reconstruction following cystectomy: experience and results in 126 patients using the Kock ileal reservoir with bilateral ureteroileal urethrostomy

Between May 1986 and February 1990, 126 consecutive men underwent lower urinary tract reconstruction by means of bilateral ureteroileal urethrostomy using a Kock ileal reservoir. The early complication rate was 11.1%. Late complications requiring rehospitalization or reoperation have been surprisingly few: 1 for prolapse of the afferent antirefluxing nipple valve, 1 for calculi and 4 for artificial urinary sphincter placement due to unsatisfactory continence. Good continence has been achieved in 94% of the patients during the day and in 84% at night. Tumor recurred in the pelvis in 5 patients, with 4 requiring cutaneous urinary diversion. All patients had progression or died of metastatic disease. Our experience has yielded extraordinary results in terms of patient acceptance with few late complications or need for reoperation.     

Use of external ureteral catheters and internal double J stents in a modified ileal neobladder for continent diversion: a comparative analysis

INTRODUCTION: Open-ended straight ureteral stents are typically used for the support of the ureteroileal anastomosis during the creation of an orthotopic 'S-pouch' ileal neobladder. The use of double J stents as an alternative in this setting is evaluated. MATERIALS AND METHODS: Medical charts from 43 patients undergoing radical cystectomy with formation of an ileal 'S-pouch' neobladder were retrospectively evaluated. In 30 patients (group A), a 6-Fr open-ended straight ureteral catheter was used to stent the ureteroileal anastomosis, while a double J stent was used for the same reason in 13 patients (group B). The ureteral catheter was removed 15 days after the procedure while the double J stent 3 weeks postoperatively. Hospital stay, early and late complications were evaluated for both groups during a mean follow-up period of 22.5 and 19.6 months respectively. RESULTS: Stricture of the ureteroileal anastomosis was observed in 2 (6.6%) and 1 (7.6%) patient of groups A and B respectively. All complications presented with similar rates, except for an increased but not statistically significant incidence of urethrovesical anastomotic leakage and early urinary tract infections in group B. Hospital stay was significantly (p<0.005) shorter for patients of group B (9.9 vs. 15.2 days). CONCLUSIONS: The use of double J stents to support the ureteroileal anastomosis can be used as an alternative to open-ended ureteral stents. With double J stents a shorter hospital stay was achieved with similar complication rates but a higher incidence of upper urinary tract infections.     

Ileal orthotopic neobladder (modified Hautmann) via a shorter detubularized ileal segment: experience and results

OBJECTIVE: To evaluate the clinical, urodynamic, functional, radiological and metabolic results of the ileal (modified Hautmann) orthotopic neobladder over 10 years of experience. PATIENTS AND METHODS: Between January 1992 and March 2002, 124 men (mean age 62.4 years, range 44-76) with advanced bladder cancer had a radical cystoprostatectomy and urinary diversion via an ileal orthotopic neobladder (modified Hautmann). Only 40 cm of small bowel (detubularized ileum) was used to construct the reservoir, as a modification of the method described by Hautmann. All patients were followed periodically and their data recorded. RESULTS: While no patients died during surgery six died (mortality rate was 5%) in the first 30 days afterward (two of them from causes unrelated to the urinary diversion surgery). The early reoperation rate was 14%; there were early complications not requiring surgery in 40 (34%) and later reoperation rate was required in 20.6%. The mean (range) maximum neobladder capacity was 550 (310-720) mL, the maximum intravesical pressure at maximum capacity 26.4 (11-48) cmH(2)O, and the minimum and maximum flow rates 25.2 (16-64) and 17.5 (11-30) mL/s, respectively. Day- and night-time continence rates were 92% and 90% after 4 years. While there was no electrolyte imbalance, there was mild to moderate metabolic acidosis in 58% of patients. There was no urethral tumour recurrence in any patient. CONCLUSION: Detubularization of ileum to form a neobladder gives a more favourable low-pressure and high-capacity reservoir. Therefore, a shorter ileal segment can be used for orthotopic urinary diversion, to avoid various metabolic dysfunctions when using detubularized bowel, but the surgery is not as free of complications as the original technique.     

回肠膀胱术与原位回肠尿流改道术后患者生活质量的调查评估

Quality of life after cystectomy and orthotopic neobladder versus ileal conduit urinary diversion

The impact of bladder removal and urinary diversion for patients' everyday life is largely unknown. The aims of this study were to compare subjective morbidity of ileal neobladder to the urethra versus ileal conduit urinary diversion and to elucidate its influence on quality of life. A total of 102 patients who underwent cystectomy due to a bladder malignancy were included in the study. In 69 patients (67.6%) an orthotopic neobladder and in 33 patients (32.4%) an ileal conduit was performed as urinary diversion. The compliance was 99% and mean follow-up was 37 months. All patients completed two retrospective quality of life questionnaires, namely the QLQ-C30 and a questionnaire developed at our institution to ask for urinary diversion specific items. The questioning and assessment was performed by non-urologists. The results obtained from the validated (QLQ-C30) and our own specially compiled questionnaire clearly demonstrate that patients with an orthotopic neobladder are more able to adapt to the new situation than patients with an ileal conduit. In addition, neobladder to the urethra improves the quality of life because it improves self-confidence, causes better rehabilitation as well as the restoration of leisure, professional, travelling, and social activities, and reduced risk of inadvertent loss of urine. For example, 92.8% of neobladder patients did not feel handicapped at all, and 87% did not feel sick or ill, in contrast to 51.5% and 66.7% of ileal conduit patients, respectively. Of the neobladder patients, 74.6% felt absolutely safe with the urinary diversion in contrast to 33.3% in the ileal conduit group. Only 1.5% of neobladder patients had wet clothes caused by urine leakage during the day, versus 48.5% of ileal conduit patients. Moreover, 97% of our neobladder patients would recommend the same urinary diversion to a friend suffering from the same disease, but only 36% of ileal conduit patients would do so. These results demonstrate that the quality of life is preserved to a higher degree after orthotopic neobladder than after ileal conduit urinary diversion.     

Urinary diversions after cystectomy: the association of clinical factors, complications and functional results of four different diversions

PURPOSE: We present a single institute experience of the four most widely used diversions after cystectomy in 281 patients, with an evaluation of the association between clinical factors, complication rates, functional results, and metabolic complications. MATERIALS AND METHODS: Between 1990 and 2005, 281 consecutive cystectomies were performed at our institute. Four different diversions were offered: an ileal conduit according to Bricker (IC; 118 patients), an Indiana pouch (IP; 51 patients), and orthotopic diversions after cystectomy/neobladder (N; 62 patients), or sexuality-preserving cystectomy and neobladder (SPCN; 50 patients). RESULTS: Forty-four percent developed early complications: IC 48%, IP 43%, N 42%, and SPCN 38%. High ASA score was the only variable significantly associated with early major complications (ASA 1 vs. 3: HR, 0.32; 95%CI, 0.14-0.72). Late complication rate was 51% with fewer complications in the IC group, IC 39%, IP 63%, N 59%, and SPCN 60% (HR, 0.32; 95%CI, 0.14-0.72), which was explained by fewer uncomplicated urinary tract infections (one third of all late complications) in the IC group. There were no differences in experienced late major complications. We found no significant association between tumour stage, ASA, age, preoperative radiotherapy, gender, and diversion-related complication rates. Complete daytime and nighttime continence, respectively, was achieved in 96% and 73% after IP, 90% and 67% after neobladder, and 96% and 67% after SPCN. Metabolic changes were found in 24% of the patients: 21% after IC, 26% after IP, and 28% after orthotopic diversion (neobladder and SPCN combined); low vitamin B12 was measured in 23%, 15%, and 15% respectively. CONCLUSIONS: Cystectomy with any subsequent diversion remains a procedure with considerable morbidity. High ASA score was associated with more early complications. Orthotopic diversions provide good functional results, but at the cost of more late complications compared with ileal conduits. We found no evidence that age, ASA score, positive lymph nodes, extravesical tumour growth, or previous radiotherapy were contraindications per se for any diversion.     

Continent urinary diversion after radical cystectomy: 3 years' experience

The authors performed 27 continent urinary diversions among 36 urinary diversion operations between 1992 and 1995. Fifteen orthotopic diversions (14 ileal neobladders, 1 sigma neobladder) and 12 Mainz pouch II were created. During these 3 years, 4 patients died after operation. Tumour progression was observed in four patients. Three ureteral and 1 urethral stricture developed, 1 patient had complete incontinence (after Mainz pouch II operation) and another three had stress and night incontinence. In 12 patients a modified Hautmann operation was performed (modified by the authors) and the ureters were implanted in a 15 cm long tubular afferent ileum. Also they changed the convential Goodwin technique for ureter implantation in Mainz pouch II operation and instead they used the Paquin technique for ureter reimplantation in the sigma. The authors concluded according to the literature and their own results that continent urinary diversion (ileal or sigma neobladder or Mainz pouch II) could be the first choice after radical cystectomy to achieve for these patients a better quality of life.
