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.     

Clinical outcome of orthotopic neobladder replacement in patients with a solitary functioning kidney

OBJECTIVE: To evaluate the outcome of orthotopic neobladder creation in patients with a solitary functioning renal unit at the time of surgery. METHODS: This study included a total of 18 patients (15 men and three women) with a solitary functioning kidney who underwent radical cystectomy for invasive bladder cancer followed by orthotopic neobladder replacement. Of these, an ileal, ileocolic or sigmoid colon neobladder was constructed in 11, three or four patients, respectively. Clinical data from these patients were retrospectively reviewed to clarify the significance of neobladder creation in patients with a solitary functioning kidney. RESULTS: During the observation period of this series (mean, 44.2 months; range, 15-95 months), there were nine early complications in six patients (wound infection, ileus, urine leakage and pulmonary embolism in four, three, one and one, respectively) and 10 late complications in nine patients (severe metabolic acidosis, vesicourethral anastomotic stricture, ureterointestinal anastomotic stricture and neobladder calculi in six, two, one and one, respectively). Severe metabolic acidosis occurred in six (five ileal neobladders and one ileocolic neobladder); however, there were no significant differences in preoperative renal function and serum electrolytes as well as postoperative voiding function between patients with and without severe metabolic acidosis. These six patients required administration of sodium bicarbonate, and their metabolic status was normalized thereafter. Furthermore, there were no significant differences in renal function and serum electrolytes between these two groups throughout the observation period, and none of the patients demonstrated renal deterioration. CONCLUSIONS: These findings suggest, despite the analysis including a small number of patients with a short follow-up period, orthotopic neobladder replacement could provide comparatively satisfactory results in patients with a solitary functioning kidney; hence, a solitary kidney should not be regarded as a contraindicated factor for neobladder creation after radical cystectomy.     

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.     

The "B-bladder"-an ileocolonic neobladder with a chimney: surgical technique and long-term results

OBJECTIVES: A modified version of the "Le Bag" ileocolonic neobladder with a "Studer"-like ileal chimney (B-bladder) is presented. The surgical technique, perioperative complications, and long-term results, including cancer control and continence, are described. METHODS: Twenty-nine patients underwent radical cystectomy and urinary diversion to an orthotopic ileocolonic neobladder with an ileal chimney. All operations were done by a single surgeon. Preoperative, perioperative and postoperative data were recorded. Median duration of follow-up was 3.4 years. RESULTS: The operation was technically successful in all cases. Late complications included recurrent urinary tract infection (17%) and uretero-neobladder anastomotic stricture (3%), both at acceptable rates. Postoperative daytime continence was excellent. Cancer control was satisfactory during follow-up; 11 patients (38%) died of disease progression with distant metastases. Median survival was 71.1 months. CONCLUSIONS: The B-bladder maintains the simplicity of preparation of the original "Le-Bag" neobladder while gaining the advantages of ureteral anastomosis to an ileal chimney. The incidence of perioperative complications is low and long-term results with regard to cancer control, continence, and complications are excellent.     

Orthotopic Ileal Neobladder Reconstruction after Renal Transplant

Radical cystectomy and urinary diversion is an effective curative treatment for muscle invasive bladder cancer. The orthotopic ileal neobladder has become a favorable choice of urinary diversion as it offers superior quality of life, cosmetic outcome and the potential for normal voiding. We treated two patients with bladder cancer who previously underwent renal transplant for end-stage renal disease. Radical cystectomy and orthotopic ileal neobladder reconstruction was performed in both patients. One patient had two renal transplants and underwent transplant nephrectomy at the time of cystectomy. In the other patient, the native kidneys were still present and the ureters were anastomosed to the neobladder. There is excellent function of the neobladder. There were no increased complications seen in these patients. Our cases demonstrate that an orthotopic ileal neobladder is safe and feasible after renal transplant and should be offered to these patients.     

Simplified laparoscopic radical cystectomy with orthotopic ileal neobladder creation in a porcine model

BACKGROUND AND PURPOSE: Laparoscopic radical cystectomy with orthotopic ileal neobladder creation is a technically challenging and lengthy surgical procedure. We present our experience with a simplified technique for laparoscopic cystectomy and neobladder creation in the porcine model. MATERIALS AND METHODS: Ten female minipigs underwent a purely laparoscopic radical cystectomy with orthotopic ileal neobladder creation. Nine ureterointestinal anastomoses were performed using a simplified "dunk" technique, where the ureter was prolapsed 5 mm into the afferent limb and the periureteral tissue was secured to the bowel serosa with three superficial sutures. Six ureters were not stented, and three had indwelling stents inserted. In 11 ureters, the anastomosis was performed using a running mucosa-to-mucosa technique (three with stents, eight without stents). The Lapra-Ty suture clip (Ethicon Endosurgery, Cincinnati, OH) was used to secure the running sutures on the urethra, ureters, and neobladder. Animals were harvested at 3 to 8 weeks (mean 6.5 weeks) after surgery. Serology, static cystogram, intravenous urography, and gross and histopathologic evaluations were performed. RESULTS: Of six unstented dunked ureterointestinal anastomoses, two (33%) were widely patent, two were strictured but patent, and two were completely obstructed. In the three stented ureters implanted using the dunk technique, one (33%) was widely patent, one was strictured, and one was completely obstructed. All ureterointestinal anastomoses performed with a mucosa-to-mucosa running anastomosis, whether stented (three ureters) or not stented (eight ureters), were widely patent. Lapra-Ty clip migration into the neobladder pouch caused urethral obstruction resulting in delayed bladder perforation in two animals. CONCLUSIONS: Laparoscopic cystectomy and ileal neobladder creation is technically feasible. Attempts to simplify the ureterointestinal anastomosis require further evaluation and modification. Stent placement appears to be unnecessary in the laparoscopic ureterointestinal anastomosis. Laparoscopic creation of the ileal neobladder remains a technically challenging procedure.     

Orthotopic ileal neobladder reconstruction in patients with recurring bladder cancer after renal transplantation – a report of two cases and a review of the literature

Abstract:  Renal transplant recipients have a high risk of developing multiple and invasive urothelial tumors because of long-term immunosuppression and infections with oncogenic viruses in China. However, treatment of renal transplant recipients who developed invasive bladder tumor is challenging. We aimed to evaluate the efficacy and safety of orthotopic ileal neobladder reconstruction following radical cystectomy in renal transplant recipients. Orthotopic ileal neobladder reconstruction and preservation of the transplanted kidney were performed in two patients after one and 36 months of transplantation, respectively. One recipient was lacking a bladder because of prior cystectomy before the transplantation, and the other developed multiple and invasive bladder cancer after the transplantation. During the 14-month and seven-yr follow-up postoperation, no serious complications occurred except slight hydronephrosis in one patient. No rejection and graft dysfunction occurred in both patients with reduced dosage of immunosuppressants, and serum creatinine as a marker of renal function remained stable. Urinary continence was satisfactory during the day and night with voluntary voiding. Our experience showed that radical cystectomy and orthotopic ileal neobladder reconstruction in transplant patients with stable renal function is a safe and effective way to provide better quality of life, satisfactory urinary diversion and preservation of renal function simultaneously.     

Ileal Neobladder for Bladder Substitution after Radical Cystectomy

Background: Studer's ileal neobladder is technically simple, and favorable clinical results have been reported. However, there have been only a few follow-up studies on this type of ileal neobladder. We reviewed the clinical outcomes of patients who received Studer's ileal neobladder, with a minor modification, in our institution.
Methods: Twenty-five men underwent bladder reconstruction with Studer's ileal neobladder after radical cystectomy. The function of the ileal neobladder and voiding status were evaluated during follow-up. The follow-up period ranged from 3 to 42 months (mean, 24 months).
Results: The ileal neobladder achieved a large capacity at a low basal pressure, associated with a relatively low complication rate directly related to the neobladder. At 12 months after surgery, daytime and nighttime continence rates were 90|X% and 74|X%, respectively. In 5 patients who were incontinent, the maximal urethral closure pressure was statistically lower than in patients with continence.
Conclusion: Studer's ileal neobladder is an easy operative procedure for bladder substitution, and has a relatively low complication rate directly related to the neobladder. Good compliance ofthe pouch and preservation of the external sphincter mechanism are the most important factors for achieving urinary continence, after construction of the ileal neobladder.     

Voiding function and sexual activity in patients following Hautmann neobladder construction

PURPOSE: We retrospectively evaluated the outcome of Hautmann neobladder reconstruction in terms of complications, lower urinary tract symptoms, and sexual function in a large group of patients who underwent radical cystectomy. METHODS: We reviewed the medical records of 118 patients (105 men and 13 women) who underwent radical cystectomy and Hautmann neobladder construction at the Gifu University Hospital or one of its affiliate hospitals between Jan 1993 and Dec 1999. The 118 patients were asked to complete a questionnaire regarding lower urinary tract symptoms and sexual activity, and the data was compiled. RESULTS: The mean follow-up period was 50.4 months (range, 6.8-88.2). Early complications comprised wound infection (in 17.8% of patients) and ileus (in 10.1% of patients). Late complications comprised ileus, pyelonephritis, stone, and stricture of the pouch-urethral anastomosis, each of which occurred in 3.4% of patients. Eighty-one (73 men and 8 women, 72.9%) of 90 surviving patients replied to the questionnaire. Seventy-seven (95.1%) of these patients reported spontaneous micturition, whereas 4 (4.9%) patients required intermittent self-catheterization. The mean total I-PSS was 11.6 points. Twenty-five percent of patients experienced interrupted voiding almost always; 38% of patients did not experience this at all. Approximately 26% of patients experienced weak urinary streams; 36% did not. Daytime continence was achieved in 97.3% of patients; nighttime incontinence was present in 61.3%. Preoperatively, 79.7% of the men were capable of sexual intercourse. Postoperatively, 63.6% of men who underwent radical cystectomy with the nerve-sparing procedure were capable of sexual intercourse, whereas only 14.8% of men who underwent radical cystectomy without the nerve-sparing procedure were. CONCLUSIONS: Morbidity rates were acceptable and functional outcome was excellent in this rather large group of patients who underwent Hautmann neobladder construction. Some problems have not been fully overcome, however, i.e., nocturnal incontinence and sexual dysfunction.     

Results of the ureteral reimplantation with serous-lined extramural tunnel in orthotopic ileal W-neobladder

Background: Our experience in uretero‐ileal anastomosis using the serous‐lined extramural tunnel in orthotopic ileal W‐neobladder is presented. Methods: Between June 1998 and November 2001, 42 patients (40 men and two women) underwent radical cystectomy and orthotopic ileal neobladder for invasive bladder cancer. The ureters were reimplanted into serous‐lined extramural tunnels as described by Abol‐Enein and Ghoneim. However, we made minor modifications during the ureteral reimplantation in cases that necessitated distal ureteral excision and with grossly dilated ureters. Evaluation included clinical and radiographic studies to determine functional and oncological outcomes. Results: There was no operative mortality. The mean follow‐up period was 28 months (range 12–52). Early complications occurred in four patients (9.5%). An endarterectomy for acute popliteal arterial embolism, the excision of the pouchointestinal fistula and a temporary colostomy were performed in two of these four patients. The other two patients were treated conservatively. Late complications occurred in eight patients (19%). Reflux was observed in three renal units (3.7%), ureterointestinal strictures in another three renal units (3.7%) and urethroileal stenosis in two patients (4.8%). In all cases, stabilization or improvement of renal function was achieved. No metabolic complications were observed. Conclusions: Ileal W‐neobladder with a serous‐lined extramural tunnel is a safe, reliable form of lower urinary tract reconstruction. The method can be carried out with equal ease in grossly dilated ureters and in cases that necessitate distal ureteral excision.     

Complications and neobladder function of the Hautmann orthotopic ileal neobladder

OBJECTIVE: To report the complications and function of the Hautmann orthotopic ileal neobladder . PATIENTS AND METHODS: In a 6.5-year period, 67 patients had an ileal neobladder constructed after radical cystectomy as treatment for invasive carcinoma of the bladder. All complications were reported systematically. Neobladder function was assessed by patient interviews, uroflowmetry and cystometric analyses. RESULTS: There were early complications in 41 patients (61%), and late complications in 32 (48%); 23 (34%) had both early and late complications and 17 (25%) had none. Eighteen of the patients (27%) required a re-operation for complications. At the 4-month follow-up, 90% were continent during the day and 65% during the night; at 1 year after surgery 95% were continent during the day and 73% during the night. The functional bladder capacity and maximum cystometric capacity were close to the natural bladder volume (median 450 and 480 mL, respectively). CONCLUSIONS: Despite the high rate of complications in this study, most were considered as minor and could be treated by conservative or minimally invasive methods. The neobladder had an acceptable resemblance to the native bladder in capacity and function. Consequently the ileal neobladder might be preferred as a urinary diversion after radical cystectomy, if no contraindications are present.     

Long-term results of standard procedures in urology: the ileal neobladder

Over the past 20 years orthotopic urinary reconstruction with the techniques developed at Ulm and Bern has become a widely accepted form of urinary diversion. So far, both centers together have performed more than 1,300 orthotopic bladder substitutions with an overall rate of neobladder formation in 58% of all cystectomized patients. Today, the absolute contraindications for this procedure are urinary stress incontinence, damaged rhabdosphincter, severely impaired renal and liver function, severe intestinal diseases or an oncologic situation requiring urethrectomy. In patients treated for transitional cell carcinoma of the bladder, the rate of urethral recurrence in both centers was 1.5 and 5%, respectively, and the rate of upper urinary tract recurrence was 2–3%. Local tumor recurrence usually did not affect neobladder function. The rate of outlet obstruction by local recurrence was 2%, that of gross hematuria 1%, and of entero-reservoir fistulas 1–2%. Daytime continence at 12 months was 92%, while nighttime continence was lower around 80%. Transient or permanent urinary retention was seen in 11–12% of male patients. In both series, long-term upper urinary tract safety was good. The risk of stenoses of the uretero-intestinal anastomosis with consecutive loss of renal function decreased with the introduction of non-refluxing implantation techniques. The rate of long-term metabolic complications remains low when adequate substitution with sodium bicarbonate is guaranteed in patients with impaired renal function. Patient selection and meticulous postoperative follow-up contributed to achieve good long-term results after cystectomy and orthotopic ileal neobladder substitution of the two large series of patients from the Universities of Ulm and Bern.     

Experience with the orthotopic ileal neobladder in women: a mid-term follow-up

OBJECTIVE: To report our experience with orthotopic bladder reconstruction in women, as currently the ileal orthotopic neobladder is the diversion of choice for women requiring a bladder substitute at our institution. PATIENTS AND METHODS: From February 1995 to March 2001, 29 women with muscle-invasive bladder carcinoma underwent a nerve-sparing radical cystectomy and had an orthotopic ileal neobladder reconstructed. The outcome was evaluated at 2 and 6 months and then yearly, by a clinical history, physical examination, voiding diary, stress test and estimate of functional neobladder capacity. RESULTS: All patients were followed for at least 14 months (mean 27.5); there were no major complications related to the surgery. The mean (range) neobladder capacity 2 months after surgery was 250 (190-320) mL; at 6 months it increased, remaining stable for the remaining follow-up, at 450 (350-700) mL. Four patients (14%) had nocturnal incontinence and one stress urinary incontinence, associated with using three pads per day. Three patients (10%) required catheterization for a postvoid urinary residual of >100 mL. Of the 29 patients, seven died with metastatic disease and three from causes unrelated to the reservoir or bladder cancer. Currently, 19 patients (65%) are alive and disease-free, with a mean follow-up of 35 months. CONCLUSION: Orthotopic neobladder reconstruction in women, using 40 cm of ileum, is safe and gives high continence and low urinary retention rates. Therefore, it should be advised as the first option in women with good renal function and a tumour-free bladder neck.

Orthotopic bladder substitute in renal transplant recipients: experience with Studer technique and literature review

Renal transplant recipients with high‐risk bladder cancer following cystectomy need a urinary diversion preserving the renal function and possibly maintaining body image, while still offering the best oncological outcome. The aim of this report is to describe our experience of radical cystectomy and orthotopic ileal neobladder with Studer technique in this population, and to review the literature. We performed radical cystectomy and Studer ileal neobladder in four male patients (median age 67 years) after median time of 9.5 years following renal transplantation. Pathology revealed pT1HGN+ transitional cell carcinoma in one case, pT1HGN0 in two and pT3aHGN0 in one. Two patients presenting aggressive disease (N+ and pT3a) died of tumour progression after 20 and 14 months, respectively, while the other two are alive after 56 and 36 months of follow‐up with no evidence of disease, stable serum creatinine (2.29 and 1.6 mg/dl) and mild metabolic acidosis. Day and night‐time urinary continence were satisfactory in all patients. Good functional outcomes have been reported in the 20 cases of ileal orthotopic neobladder with different techniques published so far and the global experience of 24 cases with a median follow‐up of 39 months documents a cancer specific survival of 62.5%.

National survey on orthotopic neobladder

Objective A national survey was conducted among the urologists in India to find the preference for urinary diversion after radical cystectomy for muscle invasive carcinoma of the urinary bladder, percentage of neobladder reconstruction, segment of the bowel used, complication rate, need for self-intermittent catherisation on follow up and the survival. Material and methods A detailed questionnaire was mailed to all members of the urological society of India (USI) to find out their preference for urinary diversion following radical cystectomy for muscle invasive carcinoma urinary bladder. For the neobladder reconstruction, they were asked for the type of bowel segment used, complication rate, reoperation rate, need for intermittent clean catheterisation on follow up and 5-year survival. Results A total of 24 institutions responded to the mailed questionnaire. Of all institutions 12 (50%) did not prefer the orthotopic neobladder (ONB) reconstruction. Among the institutions carrying out neobladder reconstruction, majority perform ileal conduit in more than 50% of the cases. Ileum (66.66%) or ileocaecal (16.66%) segment was the choice of bowel segment for most of the urologists. Only three institutions used sigmoid colon. The complications encountered were wound infection (5–25%), burst abdomen (5%), urinary fistulas (3–25%), faecal fistulas (2–5%), bladder neck stenosis (5–15%) and ureterointestinal anastomosis stenosis (5–25%). The reoperation rate was 5–15% with a perioperative mortality of 0.5–3%. Around 10–100% (average 50%) of the patients require intermittent clean catherisation. Only seven institutions could provide 5-year survival rate data. Of these three institutions reported more than 50% and four institutes less than 50% 5-year survival. Conclusion Ileal conduit still remains the urinary diversion of choice following radical cystectomy for muscle invasive carcinoma of the bladder among most of the urologists in India. Orthotopic neobladder reconstruction is practiced only in selected centres. Wound infection, urinary leak and obstruction at ureterointestinal anastomosis are the main complications. Clean intermittent cathaterisation is required at an average of 50% of the patients to ensure complete emptying of the neobladder.     

勃起神经保留性膀胱全切Roux-y乙状结肠新膀胱的临床结果

目的:观察勃起神经保留性膀胱全切和Roux-y乙状结肠新膀胱术后患者阴茎勃起功能、尿控、排尿和肿瘤复发情况。方法:共有18例患者进行了勃起神经保留性膀胱全切和Roux-y乙状结肠新膀胱术,评价肿瘤复发情况和功能性结果(尿控、排尿、勃起功能)。结果:平均随访41个月,2例分别于术后10个月和15个月死于癌症广泛性转移,这2例均为盆腔淋巴结阳性的患者。白天和夜间尿控率均为100%,11例患者有阴茎勃起功能,勃起率达61.1%,2例患者勃起功能受损,5例无勃起功能,手术前后ⅡEF-5评分为(13.72±6.39)、(10.83±8.25)分,差异有显著性(P<0.05)。结论:勃起神经保留性膀胱全切和Roux-y乙状结肠新膀胱术后患者阴茎勃起功能和尿控情况良好,肿瘤复发情况尚可接受,但仍需要长时间随访和大样本患者证实。
