Establishment and practical effect of comprehensive clinical management for out patients with orthotopic new bladder based on doctor-nurse cooperation / 中国实用护理杂志

Objective:To build a comprehensive clinical management of outpatient with orthotopic neobladder based on doctor-nurse cooperation to provide overall service to patients.Methods:The comprehensive clinical management was established in October 2018, 32 patients were collected retrospectively from January 2009 to before the establishment of the clinic, and 14 patients were collected from the establishment of the clinic to January 2020. After the establishment of the clinic, the comprehensive management mode was adopted, including the medical team implementing management from the aspects of implementing doctor-patient joint decision-making, guiding patients to carry out pelvic floor muscle rehabilitation training, teaching family members to carry out new bladder irrigation, and establishing patients′ records. Before the establishment of the clinic, there was no specialized personnel for unified management, and the doctor for new bladder irrigation and so on.Results:The rate of complete urinary control in the 46 patients with orthotopic neobladder was 82.6%(38/46) in the day and 71.7%(33/46) in the night. The rates of complete urine control of patients in the day and night were 12/14 and 9/14 after the establishment of the clinic. The length of stay which was (13.36 ± 9.44) d, and feeding time which was (5.00 ± 2.11) d of the patients after the establishment of the clinic were both less than those of the patients before the establishment of the clinic, which were (17.28 ± 9.98) d and (5.78 ± 2.90) d, but the differences were not statistically significant ( t values were -1.247 and -0.905 respectively, both P>0.05). However, for diurnal and night-time urine control, the proportion of people with more than one diaper was better after the establishment of outpatient clinic than before. Conclusions:The establishment of the comprehensive clinical management meets the needs of patients with orthotopic neobladder, enables patients to get the function of continence and urination sooner, and contributes to improve the clinical outcome of patients.

The feasibility and efficacy of total laparoscopic radical cystectomy with intracorporeal Xing's orthotopic neobladder / 中华泌尿外科杂志

Objective To explore the feasibility and clinical effect of laparoscopic radical cystectomy with intracorporeal Xing's orthotopic neobladder.Methods Forty-one patients who underwent laparoscopic radical cystectomy with intracorporeal Xing's orthotopic neobladder from July 2013 to August 2019.There were 31 cases performed in Beijing Chaoyang hospital and 10 cases in National Cancer Center.Mean age was 59 (range 44-78) years,mean BMI was 25.3 (range 20.1-34.7) kg/m2,and mean CCI was 3 (range 2-6).No urethral stricture or urinary incontinence was found by preoperative examination.No distant metastasis was identified by bone scans,chest X-ray and sonography.Cystoscopy or TURBT was performed on all patients and biopsy was taken to confirm the diagnosis.Preoperative pathology showed 30 cases (73.2％) of MIBC,9 cases of NMIBC (22.0％) and 2 cases (4.9％) of in-situ cancer.Laparoscopic radical cystectomy and lymphadenectomy were performed under general anesthesia.Urinary diversion was completed in the peritoneal cavity,by intercepting the terminal ileum about 60 cm,and taking the proximal ileum 10 cm as input loop on the right side with proximal to distal way,and the middle 40 cm ileum was detubated.After u-shaped suture,the ileum was folded back and stitched into a sphere building a novd orthotopic neobladder with bilateral isoperistaltic afferent limbs.The prognosis of perioperative data and postoperative satisfaction regarding continence were analyzed,continence was defined as 0-1 pad/day.The 41 patients were divided into two groups to compare the difference in term of operation time and blood loss between the first 21 patients and the last 20 patients.Results Mean total operative time was 324.9 mins (range 210-480) mins,and mean estimated blood loss was 177.6(range 50-700) ml.There were significant statistical differences in term of total operation time,construction time and blood loss between the first 21 patients and the next 20 patients (P ＜ 0.05).Postoperative pathological results were urothelial carcinoma in 40 cases (2 in situ carcinoma) and small cell carcinoma in 1 case.Mean number of dissected lymph nodes was 19 (range 11-58),with 7 cases(17.1％)of positive lymph nodes,and 3 cases(7.3％) had positive surgical margin.At a mean follow up of 17.6 (range 2-64) months,36 patients (87.8％) survived,including 2 patients (4.9％) with metastasis and 1 patient (2.4％) with recurrence,and 5 cases (12.2％)died.All patients were able to urinate without catheterization.Thirty-seven patients (90.2％) were satisfied with voiding control during the daytime (0-1 urinal pad),and 29 patients (70.7％) were satisfied with voiding control at nighttime (0-1 urinal pad) by the follow-up 12 months after the operation.Conclusions Total laparoscopic radical cystectomy combined with Xing's orthotopic ileum neobladder is a simple method with fewer postoperative complications and a satisfactory continence rate.

Research progress on prevention and intervention of incision-related complications after orthotopic neobladder surgery for bladder cancer / 中国肿瘤临床

The incidence of bladder cancer is increasing in China. Each year, nearly one third of newly diagnosed cases are muscle invasive bladder cancer (MIBC). The standard treatment for patients with MIBC is radical cystectomy (RC) with pelvic lymphadenectomy. Orthotopic neobladder (ONB) surgery is the primary method of urinary diversion after RC. However, ONB surgery is associated with many post-operative complications related to the urinary tract, intestine, and incision site. Here, we review the mechanism, prevention, and treatment measures of incision complications after ONB surgery.

Clinical application of sigmoid orthotopic neobladder after radical cystectomy in treatment of invasive bladder cancer:A report of 1 6 cases / 吉林大学学报(医学版)

Objective:To investigate the clinlic therapeutic effect of sigmoid orthotopic neobladder after radical cystectomy in the treatment of invasive bladder cancer.Methods:1 6 patients with invasive bladder cancer (all males;age range from 53 to 75 years)were admitted and underwent radical cystectomy and sigmoid orthotopic neobladder.Results:Sixteen patients were hospitalized for 37 to 62 d,with an average of 51 d.All patients were followed up for a mean of 26 months (range from 5 months to 6 years).The serum creatinine (Cr)and blood urea nitrogen (BUN)levels were both in the normal range and there was no acidosis in all the cases. No case had unilateral ureteral urine reflux during cystography. Of the 16 patients 14 cases (87.5%) achieved continence during daytime;6 cases (37.5%) were incontinent at night, but all of them could control urination by being woken up at night.The capacity of the neobladder was 245 to 380 mL with an average of 316 mL and the maximal pressure of the neobladder during filling was 28 to 57 cm H2 O (1 cm H2 O =0.098 kPa)with an average of 39 cm H2 O.Conclusion:As an operation the sigmoid orthotopic neobladder can be performed easily without serious postoperative complications and has more reliable results. This operation may be generally applied in clinical practice.

Total cystectomy and W-shaped orthotopic ileal neobladder for bladder cancer / 中南大学学报(医学版)

Objective: To investigate the clinical effect of total cystectomy and W-shaped orthotopic ileal neobladder for bladder cancer. Methods: Total cystectomy and W-shaped orthotopic ileal neobladder were performed on 29 male patients and 3 female patients. Atfer the cystectomy, 35-40 cm terminal ileal segment was isolated to make W-shaped orthotopic ileal neobladder. Bilateral uretero-ileal anastomoses were constructed by nipple technique, urethral stump was sutured to the lowest portion of the ileal pouch. Results: All surgeries were completed successfully. Patients were able to void by increasing the abdominal pressure, daytime continence rate was 87.5% and nighttime continence rate was 78.1%. The mean neobladder capacity was 410.6 mL and the mean postvoid residual urine was22.7 mL at 6 months. After the surgery, ileal neobladder leakage occurred in 3 (9.4%) patients, mild ileus occurred in 2 (6.3%) patients, ileo-urethral anastomosis stricture developed in 1(3.1%) patient, and dysuria occurred in 3 (9.4%) patients because of the mucus.HTe complications were treated properly and satisfactory results were obtained. Erection was preserved in 5 of the 9 male patients with normal erectile function, and normal sexual function was preserved in 1 female patient who underwent uterus-sparing cystectomy. HTe mean follow-up was 15 months.One patient died of distant metastasis and pneumonia, while other patients survived without tumor. Conclusion: Total cystectomy and W-shaped orthotopic ileal neobladder have the advantages of voiding through the native urethra, satisfactory continence, low complication rates of upper urinary tract damage and electrolyte imbalance. W-shaped orthotopic ileal neobladder may be considered as the ifrst option of urinary diversion atfer cystectomy. Postoperative management should focus on complications and follow-up.

Trece años de experiencia en el manejo de cáncer vesical con neovejiga ortotópica de Studer / Management of bladder cancer with Studer orthotopic neobladder: 13-year experience

Introducción: Posterior a la cistectomía radical, la derivaciones urinarias ortotópicas han tomado importancia en los últimos años. El objetivo de este informe es presentar los resultados en pacientes sometidos a derivación urinaria ortotópica tipo Studer posterior a cistectomía radical. Material y métodos: Se revisaron expedientes de pacientes con cáncer vesical sometidos a cistectomía radical más realización de neovejiga ileal entre enero de 1992 y diciembre de 2004. Resultados: De los 306 pacientes operados de cistectomía radial con derivación urinaria, se incluyeron 42 (13.7 %) pacientes en quienes la derivación urinaria fue neovejiga tipo Studer, 34 (80.9 %) hombres y ocho (19.1 %) mujeres, con una edad promedio de 60 años. El tiempo quirúrgico promedio fue de siete horas, con sangrado promedio de 1600 ml, requiriendo ingreso a unidad de terapia intensiva 55 % de los casos. La complicación temprana más frecuente fue la acidosis metabólica, presente en 28 (66 %) pacientes, y la más grave fue la fuga urinaria uretero-ileal, en siete (16.6 %). Entre las complicaciones tardías más importantes destacan la incontinencia urinaria diurna y nocturna, frecuentemente relacionadas a infecciones de vías urinarias y oclusión intestinal. A cinco años de seguimiento, la sobrevida global fue de 71 %, la mortalidad específica por cáncer fue de 15 % y la mortalidad relacionada a la cirugía de 7.3 %. Conclusiones: La realización de neovejigas ortotópicas es reproducible en centros con experiencia y una alternativa a la derivación urinaria heterotópica con conducto ileal.

BACKGROUND: We present the results of patients submitted to a Studer type urinary orthotopic derivation after radical cystectomy. METHODS: The files of patients with bladder cancer submitted to a radical cystectomy plus the procedure of the ileal neobladder were reviewed in our hospital from January 1992 until December 2004. Patients were divided into two groups: group A--60 years old or younger and group B-->60 years old. RESULTS: From 306 patients submitted to radical cystectomy with urinary derivation, there were 42 patients (13.7%) included with Studer type neobladder. There were 34 (80.9 %) men and 8 (19.1%) women, with an average age of 60 years. Average surgical time was 7 h with an average blood loss of 1600 cc requiring transfer to intensive care unit (ICU) in 55% of the cases. The most frequent early complication was metabolic acidosis that was present in 28 (66%) patients. The most severe complication was ileal-ureter urinary leak, which was present in seven (16.6 %) patients. Among the most frequent late complications are the day- and night-time urinary incontinence often related to urinary infections and intestinal occlusion. Overall 5-year survival was 71%, cancer-specific mortality was 15% and surgical-related mortality was 7.3%. CONCLUSIONS: The performance of procedures with orthotopic neobladders is actually feasible in experienced hospital centers and is a valuable alternative to urinary heterotopic derivation with ileal conduit. Postoperative patient management and regular follow-up is of major importance.

Long term follow up of patients with the ileal orthotopic neobladder / 中华泌尿外科杂志

Objective To discuss the long term clinical effect of ileal orthotropic neobladder.Methods From 1991 to 1998,79 patients,mean age 55(41～75)years,male 74,female 6,were followed up.The serum creatinine and urea,electrolytes,blood routine,B ultrasonic scan of the neobladder residual urine and IVU or MRU of the patients were followed up.The max transverse diameter of renal pelvis and the max verticaI/level diameter of neobladder were measured in 5,10 to 14,15 years of postoperative when IVU or MRU.All results of different time were compared by the multiple comparisons.The local or distant cancer recurrence and the complications of the operation Were evaluated. Results Sixty-four cases,58 male,6 famle,were long term followed up:mean time was 167 (range,121～216)months.Seven cases died of other diseases.Seven cases had pelvic recarrence.Two cases had urethral recurrence.Three cases died of tumor metastasis.One case had ureter recurrence.Forty-eight patients were alive more than 10 years.The value of the serum creatinine,urea,electrolytes and bloods routine of the patients were normal after 5,10 to 14 and 15 vears postoperative (P＞0.05).The max transverse diameter of the renal pelvis in 5,10 to 14 and 15 years Dostoperative were 14.0 mm,14.1 mm and 13.7 mm,respectively,P＞0.05.The max vertical/level diameter of the neobladder in 5,10 to 14,15 years of postoperative were 110.4 mm/90.4 mm,111.5 mm/95.3mm and 127.0 mm/97.0 mm,respectively,P＞0.05.The residual urine of 5 cases was more than 50 ml and had not increased during follow up.Eight cases with neobladder stone were cured by the intracavitary lithothrypsis.Two cases with uretheral stricture were cured by the intracavitary therapy.Twelve cases of 14 cases with inguinal hernia were cured by reoperation,2 cases accepted conservative treatment.Only 17 cases had no complication involve of the cancer and the operation. Conclusion The upper urinary tract and neobladder of the ileal orthotopic neobladder could be stable for long time,the cure rate of tumor is satisfactory and the lifetime follow up is necessary.

Neovejiga ileal ortotópica en mujeres / Orthotopic ileal neobladder in women

Introducción: En la actualidad existe consenso en que el método ideal de derivación urinaria luego de la cistectomía radical es la neovejiga ortotópica construida con un segmento detubulizado de intestino. Sin embargo no fue sino hasta hace pocos años que esta alternativa se ha considerado válida en mujeres, al constatar que es seguro preservar la uretra desde el punto de vista oncológico y que los resultados funcionales son adecuados. Presentamos una serie de pacientes sometidas a cistectomía por diferentes indicaciones en quienes se reconstituyó la vía urinaria con una neovejiga ileal ortotópica. Material y métodos: Se analizan los resultados de 6 pacientes sometidas a cistectomía y reconstrucción de la vía urinaria con una neovejiga ortotópica. Se realizaron 2 exanteraciones anteriores por cáncer vesical invasor y 4 cistectomías totales por cistitis intersticial en 2 casos, por cistitis actínica en 1 caso y por cistitis eosinofílica en 1 caso. La neovejiga se confeccionó en todos los casos con íleon desfuncionalizado, detubularizado y reconfigurado en forma esférica, anastomosado a la uretra y a ambos ureteres. Resultados: Ninguna de las pacientes de esta serie presentó complicaciones en el intraoperatorio ni en el postoperatorio inmediato. Con un seguimiento que va entre los 5 y 12 años todas las pacientes se encuentran vivas y orinando por la uretra nativa. Dos pacientes tienen continencia completa, una paciente tiene incontinencia nocturna y tres pacientes necesitan autocateterismo. Una de las últimas desarrolló una litiasis en la neovejiga. Todas las pacientes se encuentran satisfechas con su derivación urinaria. Conclusión: La neovejiga ortotópica es una alternativa válida luego de la cistectomía en mujeres seleccionadas, con resultados comparables a los obtenidos en hombres. Debiera ser la derivación urinaria de elección si se cumplen los criterios de selección y técnica quirúrgica.

Introduction: Current consensus places orthotopic ileal neobladder as the best option for bladder substitution alter radical cystectomy. However, recently this technique has gained wide acceptance in female patients only after it was proven safe to preserve urethra in an oncological setting. We report a series of female patients that underwent radical cystectomy and orthotopic ileal neobladder. Material and methods: Results in 6 patients that underwent radical cystectomy with ileal neobladder are analyzed. Two anterior exanterations for invasive bladder cancer and 2 total cystectomies for interstitial cystitis and 1 for actinic and eosinophilic cystitis respectively. In all cases neobladder was made out of detubularized ileon reconfigured as a pouch and anastomosed to the urethra and ureters. Results: None of the patients presented intraoperative or postoperative complications. Follow-up varied between 5 and 12 years. All patients are alive and urinating through their native urethra. Two patients have complete continence, one patient presents only day continence and 3 patients require authocatheterism, one of them presented with bladder stone. All patients are satisfied with their urinary diversion. Conclusion: Ileal neobladder is a valid alternative for bladder substitution in selected female patients. Results are comparable with the ones obtained in male patients. It should be the diversion of choice if selection and technical criteria are met.

Feasibility of QOL score in functional assessment of orthotopic neobladder after radical cystectomy / 中华泌尿外科杂志

Objective To estimate the feasibility of QOL score in functional assessment of or-thotopic neobladder after radical cystectomy. Methods Questionnaire survey,QOL score sheet and urodynamic examination were done in 22 patients with orthotopic neobladder.Investigations were fo-CUS on the micturition interval during daytime and nighttime.Micturition time,degree of incontinence and their relationship with QOI.scores and urodynamic parameters wete also analyzed. ResuIts There were 3,6,7,1,2,3 and 0 cases which QOI.score were 0 to 6 accordingly.In the dav time,2 patients complained a light incontinence while 1 patient of moderate incontinence.In the nighttime.3 patients had the complaint of moderate incontinence while 4 patients of light incontinence.The average daytime mlcturltlon interval was 136 min(45-210 rain).The average maximum urinary flow rate,maximal urethral closure pressure and postvoid residual were 12.9 ml/s(2.7-22.1 ml/s),69.3 cm H2O(33-114 em H20)and 91.8 ml(5-300 m1)respectively.QOL scores had D.sitive correlation with the degree of incontinence during daytime and nighttime(daytime:r-0.510,P=0.015,night time:r=0.911,P<0.001).The QOL scores had negative correlation with daytime micturition inter-val(r=-0.749,P<0.001).The factors which influenced the QOL scores included the maximaI ure-thral closure pressure,postvoid residual and the maximum urinary flow rate. Conclusions QOL score reflects the patients"continent ability,subjective feelings on quality of life.It is correlated with the common urodynamic parameters.QOI.score might be used as a new index to estimate the function of orthotopic neobladder.

Cistoprostatectomía radical laparoscópica con confección extracorpórea de neovejiga ortotópica: comunicación preliminar / Laparoscopic radical cystoprostatectomy and continent orthotopic neobladder performed extracorporeally: preliminary experience

Objetivo: Presentamos un abordaje quirúrgico para el manejo de pacientes con carcinoma vesical en candidatos a cirugía radical, buscando reunir los beneficios de la cirugía abierta tradicional, con las ventajas de la técnica laparoscópica. Material y Método: Se presenta una serie inicial de 5 pacientes de sexo masculino, llevados a cistoprostatectomía radical laparoscópica (CPRL) con confección extracorpórea de neovejiga ortotópica entre junio y septiembre de 2002. La edad promedio fue 50.6 años (rango: 29 a 70 años). La indicación quirúrgica fue carcinoma vesical infiltrante en cuatro de los cinco pacientes, uno de ellos previamente tratado con radioterapia. La técnica quirúrgica se presenta en 3 pasos. En el primero se realiza la linfadenectomía pelviana bilateral y la cistoprostatectomía radical (CPR) por laparoscopía; la segunda parte esta representada por la confección de la neovejiga, realizada completamente extracorpórea, y el tercer paso es la anastomosis uretra-neovejiga, desarrollada con técnica laparoscópica. Resultados: La técnica fue reproducida en los 5 pacientes. El tiempo operatorio promedio fue de 5.4 horas (rango: 4.5-7 horas). El sangrado promedio fue 410 ml (rango: 200-800 ml). Ninguno de los pacientes requirió transfusión sanguínea. El tiempo de hospitalización total varió entre 5 y 12 días, con un promedio de 6.8 días. Conclusión: La CPR puede realizarse completamente con técnica laparoscópica cuando se dispone de un adecuado entrenamiento laparoscópico. Con la técnica combinada que desarrollamos, la parte más complicada de la cirugía, representada por la elaboración de la neovejiga y el neoimplante ureteral, se realiza de forma convencional, haciendo que esta técnica sea totalmente reproducible.

Objective: We present our preliminary experience with laparoscopic radical cystoprostatectomy and continent orthotopic neobladder performed extracorporeally. We believe that this surgical approach combines the advantages of minimally invasive laparoscopy with the speed and safety of open surgery. Material and Method: Between June and September 2002, 5 male patients underwent to laparoscopic radical cystoprostatectomy and continent orthotopic neobladder performed extracorporeally. Average age was 50.6 years (range: 29-70). The operative indication was muscle-invasive carcinoma of the urinary bladder in 4 patients. One of these 4 patients was previously treated with radiotherapy. Our technique has 3 steps. Cystoprostatectomy and pelvic lymph node dissections are performed laparoscopically using five ports by a transperitoneal approach. We remove the surgical specimens through a 5 cm infraumbilical incision and through the same incision an ileal loop is extracted from the abdominal cavity, isolated, detubularized and neobladder is reconfigured. Finally, urethro-neobladder anastomosis is formed with laparoscopic technique. Results: Surgical technique was reproduced in all 5 patients. Mean operative time was 5.4 hours (range: 4.5-7). Mean blood loss was 410 ml (range: 200-800) and not transfusion was indicated. Mean hospital stay was 6.8 days (range: 5-12). Conclusion: Laparoscopic radical cystectomy is feasible when surgical team has experience in laparoscopic surgery. The most technically demanding steps of the procedure are neobladder confection and ureteral neoimplante, which are performed extracorporeally. We believe that with our combined approach, this technique is completely reproducible.

The effects of partial prostatic capsula sparing surgery on intestinal orthotopic neobladder / 中华泌尿外科杂志

Objective To investigate the effects of partial prostatic capsula and surrounding striated sphincter sparing surgery on the function of intestinal orthotopic neobladder. Methods Total cystectomy and orthotopic intestinal neobladder was performed in 23 male patients with invasive bladder cancer. The patients were divided into classical cystectomy group (n=10) and modified cystectomy group (n=13).In the classical group the prostate was removed completely and the residual urethra was anastomosed with the neobladder using interrupted suture.In the modified group transurethral resection of the prostate preceded the cystectomy,and the prostatic capsula below the verumontanum with its surrounding striated urethral sphincter was retained.The neobladder was anastomosed with the residual capsula using continuous suture.The function of the neobladder in the 2 groups was evaluated and compared. Results The pathological classification of the 23 patients was as follows:T 2aN 0M 0,13 cases;T 2bN 0M 0,6;T 1N 0M 0,1;T 3aN 0M 0,1;T 3bN 1M 0,1;T 4aN 0M 0,1.The patients were followed up for 3 to 40 months(mean,15.7 months).In modified group,11 patients survived disease-free and 2 survived with metastasis.All the 13 patients voided well with residual volume of 0 to 70 ml.Complete urinary continence was achieved in 12 patients and the remaining one had nocturnal incontinence.In classical group,10 patients survived disease-free;of them 7 voided well with residual volume of 10 to 100 ml and the other 3 needed intermittent catheterization because of their residual urine being up to 100 to 250 ml.Complete continence was achieved in 7 patients and the other 3 were incontinent(1 with incontinence day and night,2 with nocturnal incontinence). Conclusions Partial prostatic capsula and its surrounding striated sphincter sparing surgery can improve the continence and voiding of the orthotopic neobladder.$$$$

Continent urinary diversion and ileal orthotopic neobladder (report of 68 cases) / 中华泌尿外科杂志

Objective To evaluate the different methods of continent urinary diversion and the ileal orthotopic neobladder after total cystectomy. Methods 4 different kinds of continent urinary diversion were undertaken after total cystectomy for 68 cases.Continence and catheterization, volume and pressure of the reservoirs, image and hydroelectrolyte condition were investigated. Results Of the 3 cases with intussusceptive efferent tract,2 had partial deintussusception resulting in incontinence and had to be reoperated;44 cases with tapered terminal ileal efferent tract were continent and could be catheterized easily with 16～20F catheters, whereas only one case had difficulty in catheterization. 39 cases with detubularized and reshaped intestinal segment reservoirs, including 3 ileal,22 colonic and 14 ileocolonic, all achieved the demand of low intrareservoir pressure, whereas 8 cases operated in the early period had dilated reservoirs with a volume as large as 1 470～1 650 ml;8 cases with detenia cecocolonic reservoir had the volume of 430～600 ml and as intrareservoir pressure of 30～45 cmH 2O with peristalsis waves,2 of them had urine leakage in the early stage after operation.21 cases with ileal orthotopic neobladder had a volume of 350～480 ml and an intrareservoir pressure of 12～20 cm H 2O.1 being incontinent at daytime and 2 at night whereas all the others were continent. Conclusions Continent urinary reservoirs constructed by 30 cm detubularlized cecocolon can achieve the demand of low intrareservoir pressure.Detenial colonic reservoirs had more chance of urine leakage and adhesion, and higher intrareservoir pressure. Tapered terminal ileal efferent tract is better than ileal intussusception efferent tract for its excellent continence, large caliber, easy catheterization and fewer complications. Ileal orthotopic neobladder has the advantages of excellent continence, higher quality of life, but has limited indications.
