RESUMO

Urologists have always been leaders in advancing surgical technology and were the first to utilize modern robotic surgery for robotic-assisted laparoscopic radical proctectomy. Surgeon ergonomics, instrument precision, operative time, and postoperative recovery were all objectively improved. In urology, robotic surgery is now used for all intra-abdominal, retroperitoneal, and pelvic procedures and has been expanded to renal transplants and pediatric use. Modern robotic surgery has become an essential part of treating complex urologic disease in the developed world. Urologists continue to lead the way with the latest robotic surgical systems, including the newly approved single port systems.

RESUMO

The initial results robot-assisted pyeloplasty (RAP) performed on 6 patients were compared with those of laparoscopic pyeloplasty (LP) for ureteropelvic junction obstruction performed on 26 patients in a Japanese regional center. The median operating time, estimated blood loss, time to oral intake, time to start walking, and hospital stay were not significantly different between the groups. There was no difference in the rate of complications of Clavien-Dindo≥grade III between the two groups. Although the number of entered patients was small, the results indicated that RAP is feasible with favorable outcome.

RESUMO

OBJECTIVE: To characterize the bulbospongiosus muscle (BSM) in patients with bulbar urethral strictures. MATERIALS AND METHODS: We studied 21 patients divided into 2 groups: Stricture Group (n = 14; mean age = 62.00 years) with bulbar stricture submitted to open urethroplasty; and Control Group (n = 7; mean age = 60.14 years) with penile strictures (hypospadias cripples, penile cancer and/or penile infection) who were submitted to perineal urethrostomy. Samples of the BSM were dissected and histologic sections were stained by histochemical and immunohistochemical techniques. Histomorphometric analyzes were performed on photomicrographs. Means were statistically compared using the unpaired Student t test and the Mann-Whitney test (P <.05). RESULTS: The etiology of bulbar urethral stricture was idiopathic in 2 cases (14.29%), post-TURP in 6 (42.86%), post open radical prostatectomy in 5 (35.71%) and post open prostatectomy in 1 case (7.14%). The average length of the stricture was 2.08 cm. The only parameter analyzed with significant difference between the groups was the vessels (significant difference between the control group: 5.11 ± 1.98% and stricture group: 3.57 ± 1.32%, P = .0460). The quantitative analysis of collagen (Control Group: 10.63 ± 5.37% and Stricture Group: 10.83 ± 4.55%, P = .9296); diameter of BSM muscle fibers (Control Group: 41.71 ± 14.63 µm and Stricture Group: 40.11 ± 8.59 µm, P = .76 and elastic system fibers (Control Group; 3.83 ± 1.54% and Stricture Group: 5.43 ± 2.90%, P = .2601) showed no significant difference. CONCLUSIONS: Histologic analysis showed a significant decrease of the BSM vessels in urethral stricture, without changes in elastic fibers, collagen, nerves, and muscle fiber diameter. These findings show that the bulbar urethral stricture causes minimal alterations in the structure of the BSM.

RESUMO

Due to a safety alert issued by the US Food and Drug Administration (FDA) in 2011 for transvaginal mesh implants to treat female prolapse as a result of numerous reports of complications such as infection, chronic pain, dyspareunia, vaginal erosion, shrinkage and erosion into other organs nearly all industrial products have been withdrawn from the market in the meantime. The United Kingdom, Australia, and New Zealand extended warnings and prohibitions even on the implantation of midurethral slings (TVT, TOT). In view of these current international controversies regarding the use of implanted materials for the treatment of stress incontinence and prolapse and the lack of clear guidelines for the use of biomaterials, the opinion of the Working Group on Urological Functional Diagnostics and Female Urology should provide clarity. The Opinion is based on the SCENIHR Report of the "European Commission's Scientific Committee on Emerging and Newly Identified Health Risks", the "Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence" and in compliance with relevant EAU and national guidelines and the opinion of the Association for Urogynaecology and Plastic Pelvic Floor Reconstruction (AGUB eV). In addition, recommendations are given for the future handling of implants of slings and meshes for the treatment of stress incontinence and prolapse from a urologic viewpoint.

RESUMO

PURPOSE: The objective of this study was to examine national trends in the surgical management of urinary incontinence in women in the United States from 2004 to 2013. MATERIALS AND METHODS: We analyzed the CDM (Optum® de-identified Clinformatics® Data Mart) for women 18 to 64 years old and the CMS (Centers for Medicare and Medicaid Services) Medicare 5% Sample for women 65 years old or older. We created annual cross-sectional cohorts and assessed trends in the annual prevalence of urinary incontinence related surgical procedures overall and by age, race/ethnicity and geographic region. RESULTS: We observed a decline in the percent of women with urinary incontinence who underwent surgical treatment according to the CMS (from 4.7% in 2004 to 2.7% in 2013) and the CDM (from 12.5% in 2004 to 9.1% in 2013). This trend persisted independently of age, race/ethnicity and geographic region. Slings were the most common procedure but started to decline in 2011, ultimately decreasing by about 50% during the study period. Compared to other groups the prevalence of urinary incontinence related surgical procedures, including slings, was highest among women 35 to 54 years old and White women, and lowest among women residing in the Northeast. These sociodemographic patterns persisted with time. During the study period injection procedures remained stable, sacral neuromodulation increased slightly but remained uncommon and suspension decreased to nearly 0% of all anti-incontinence procedures. CONCLUSIONS: Surgical management of female urinary incontinence experienced several shifts from 2004 to 2013, including a decline in sling procedures. Age, racial/ethnic and regional differences in treatment persisted with time. Improved understanding of the drivers of these trends may help direct future development of treatments of pelvic floor disorders.

RESUMO

PURPOSE: The primary rationale for antimicrobial prophylaxis (AP) is to decrease the incidence of surgical site infection (SSI) and other preventable periprocedural infections, with the secondary goal of reducing antibiotic overuse. This Best Practice Statement (BPS) updates the prior American Urological Association (AUA) BPS and creates a comprehensive and user-friendly reference for clinicians caring for adult patients who are undergoing urologic procedures. MATERIALS AND METHODS: Recommendations are based on a review of English language peer-reviewed literature from 2006 through October 2018 and were made by consensus by a multidisciplinary panel. The search parameters included timing, re-dosing, and duration of AP across urologic procedures where there was the possibility of SSI. Excluded from the search were the management of infections outside the genitourinary (GU) tract and pediatric procedures. RESULTS: Single-dose AP is recommended for most urologic cases and antimicrobials should only be used when medically necessary, for the shortest duration possible, and not beyond case completion. Surgeons are the most accurate discerners of an SSI, and should use standard definitions to make better calculations of patient risk. The risk classification developed is dependent on the likelihood of developing SSI, and not the associated consequences of SSI. CONCLUSIONS: The AUA developed a multi-disciplinary BPS to guide clinicians on the proper usage of AP across urologic procedures and wound classifications. It is recommended that the lowest dose of antimicrobials be administered to decrease the risk of infection and to minimize the risk of drug-resistant organisms.

RESUMO

OBJECTIVE: To determine whether the presence of detrusor overactivity (DO) is associated with the 12-week and 12-month clinical outcomes of selective bladder denervation (SBD) in women with refractory overactive bladder (OAB). METHODS: Prospective single institutional study of refractory OAB females who underwent a urodynamic study and were categorized according to DO status (DO- vs DO+) prior to receiving SBD. RESULTS: Among the 23 patients, 10 were DO- and 13 were DO+. Both groups reported improvement at 12 weeks on the 24-hour pad weight test, in urgency urinary incontinence (UUI) and urgency. At 12 months, both groups still reported improvement in urgency, but only the DO- group reported reduction on the pad weight test and only the DO+ group maintained improvement in the UUI rate. Clinical success (≥50% reduction in UUI) was achieved by all DO- and by 69% of DO+ patients at 12 weeks, and by 60% of DO- and 92% of DO+ patients at 12 months. Treatment benefit (Treatment Benefit Scale ≤2) was reported in 90% of DO- and 85% of DO+ patients at 12 weeks, and in 60% of DO- and 85% of DO+ patients at 12 months. When directly comparing both group outcomes, the only significant difference was the greater reduction of UUI in the DO- group at 12 weeks (-9.0 vs -6.5; P = .045). CONCLUSION: Refractory OAB females appear to be effectively treated by SBD regardless of baseline DO status. DO status does not seem to be associated with the 12-week and 12-month outcomes of SBD.

RESUMO

BACKGROUND: According to the current definition of the German guideline for prevention of venous thromboembolism, urological surgery includes a high number of high-risk patients. All patients undergoing urological surgery between 2012 and 2016 were analyzed with regard to complications (bleeding or thrombosis). MATERIALS AND METHODS: This study is a retrospective and monocentric cohort study. Included were all patients who underwent surgery between 2012 and 2016 at the Urological Department at the University Hospital of Luebeck. Information was collected relating to anticoagulation, patient-specific and surgery-specific risk factors, and complications. RESULTS: In all, 3609 surgeries were analyzed: 77.8% of patients received no medical prophylaxis, 10.2% received an aggregation inhibitor, and 8.5% synthetic, unfractionated or low molecular weight heparin. Heparin was administered to 80.4% of patients after surgery. During an average hospital stay of 4.5 days, 93.3% of the patients received no change in anticoagulation. Merely 0.8% of all patients suffered from clinical thomboembolic events within 28 days. In contrast the number of bleedings was higher with 20.3% (minor: 4.8%, major: 15.5%). CONCLUSION: We found a slight risk for postoperative thromboembolism (0.8%). The risk for postoperative bleeding in contrast was 20.3%, including 15.5% major bleedings. The results are discussed in relation to the current guidelines.

RESUMO

OBJECTIVE: To explore a series of classic bladder exstrophy (CBE) cases referred to the authors' institution where primary closure with penile disassembly epispadias repair was complicated by penile injury. The penile disassembly technique is frequently combined with bladder closure in patients with CBE undergoing the complete primary repair of exstrophy (CPRE). Penile disassembly has been posited as a risk for penile injury by ischemic mechanisms. METHODS: A prospectively-maintained institutional database of 1337 exstrophy-epispadias complex patients was reviewed for CPRE cases referred to the authors' institution, and those with injury to the penis were identified. The location, extent of injury, and subsequent management is reported. RESULTS: One hundred and thirteen male CBE patients were referred after prior CPRE. Twenty-six (20%) were identified with penile loss and reviewed. Eighty-one percent were closed in the neonatal period, and 54% had a pelvic osteotomy. Median follow-up time was 9.9 years (range 0.6-21.3). Of 26 patients with penile loss, 77% had unilateral loss and in 23% had bilateral loss involving the glans and/or one or both corpora cavernosa. Three patients were successfully managed with myocutaneous neophalloplasty. CONCLUSION: Complete penile disassembly during bladder exstrophy closure may lead to penile injury. This major complication questions the continued application of complete penile disassembly in the reconstruction of bladder exstrophy.

RESUMO

PURPOSE: We investigated surgical approaches to urinary incontinence and long-term continence outcomes after successful bladder reconstruction in a heterogeneous patient population with classic bladder exstrophy. We hypothesized that while most patients will achieve urinary continence after surgery, only a select group will void volitionally per urethra. MATERIALS AND METHODS: An institutional database of 1,323 patients with exstrophy-epispadias complex was reviewed for patients with classic bladder exstrophy who underwent successful bladder closure and a subsequent continence procedure between 1975 and 2017. Procedures included bladder neck reconstruction, bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, and bladder neck closure with continent catheterizable stoma. Cloacal exstrophy, epispadias and variant exstrophy cases were excluded from analysis. Continence at last followup was defined as a dry interval of 3 or more hours without nighttime leakage. Those patients with more than 3 months of followup were assessed. RESULTS: Overall 432 patients underwent successful bladder closure (primary 71.5%, repeat 28.5%) and a urinary continence procedure. At last followup 162 (37%) underwent bladder neck reconstruction, 76 (18%) underwent bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, 173 (40%) underwent bladder neck closure with continent catheterizable stoma and 18 underwent other procedures. Median followup from the first continence procedure was 7.2 years (IQR 2.3-13.7). Continence was assessed in 350 patients. After isolated bladder neck reconstruction 91 of 142 patients were continent (64%, 95% CI 56-72). After bladder neck closure with continent catheterizable stoma 124 of 133 patients evaluated were continent (93%, 95% CI 87-97). CONCLUSIONS: Most patients with classic bladder exstrophy require multiple reconstructive procedures to achieve continence. Only about 25% of patients are expected to void normally per urethra without reliance on catheterization or urinary diversion.

RESUMO

PURPOSE: Opioids are frequently overprescribed after surgery. The 2018 AUA position statement on opioid use suggests using the lowest dose and potency to achieve pain control but the lack of procedure specific prescribing guidelines contributes to wide variation in prescribing patterns. To address this gap we aimed to develop opioid prescribing recommendations through an expert panel consensus. MATERIALS AND METHODS: The 15-member multidisciplinary expert panel included representatives from 5 stakeholder groups. A 3-step modified Delphi method was used to develop recommendations for postoperative opioid prescribing. Recommendations were made for opioid naïve patients without chronic pain conditions. The panel used oxycodone 5 mg equivalents to define the number of prescribed tablets. RESULTS: Procedure specific recommendations were developed for 16 endourological and minimally invasive urological procedures. The panel agreed that not all patients desire or require opioids and, thus, the minimum recommended number of opioid tablets for all procedures was 0. Consensus ranges were identified to allow prescribed quantities to be aligned with expected needs. The maximum recommended quantity varied by procedure from 0 tablets (3 procedures) to 15 tablets (6 procedures) with a median of 10 tablets. Attending urologists typically voted for higher opioid quantities than nonattending panel members. The panel identified 8 overarching strategies for opioid stewardship, including contextualizing postoperative pain management with patient goals and preferences, and maximizing nonopioid therapies. CONCLUSIONS: Procedure specific guidelines for postoperative opioid prescribing may help align individual urologist prescribing habits with consensus recommendations. These guidelines can aid quality improvement efforts to reduce overprescribing in urology.

RESUMO

Objective: To explore the pathological mechanism and role of autologous peritoneum transplantation onenterocystoplasty in porcine model. Methods: Randomly, four experimental female swine were chosen, and each of their body weight was 28-33 kg. By intravenous anesthesia, the transplantation of autologous peritoneum for bladder reconstruction operation was carried out (to transplant the peritoneum onto an ileum segment of which the mucosa and submucosa had been removed. These flaps were used to mend and augment the bladder by suturing the edge of detective bladders). After removal of ureteral catheters and balloon catheter at day 5 respectively, their voiding behaviors were monitored, and respectively 2 swine were euthanized at week 3/6 for routine pathology, immunohistochemistry, and electron microscopic examinations. Results: Four swine underwent reconstruction, but none died for complications such as peritonitis, ileus and urinary fistula. The length of ileum was 35 cm, and the area of peritoneum was 15 cm×10 cm. Voiding behaviorsof the swine were normal, with clear urine after removal of their catheters. At autopsy, reconstructed bladders were healthy. Pathological examination showed the neobladder had been covered by continuous urothelium while the peritoneum disappeared without ileal mucosa regrowth or residual. Scanning electron microscope showed that the transitional cells of neobladder of swine were complete and orderly, and urothelium around suture border was continuous withoutmalposition. Conclusions: In porcine model, autologous peritoneal transplantation witnessed no immune rejection response for itself, which was replaced by crawling transitional epithelium around anastomosis, rather than by metaplasia.

RESUMO

Objetivos: El objetivo de este estudio fue evaluar el rol de la aplicación de fluoroscopia en pacientes intervenidos mediante cirugía retrógrada intrarrenal y su efecto sobre los resultados quirúrgicos. Material y métodos: Los pacientes que ingresaron en nuestro centro con diagnóstico de cálculos renales se dividieron en 2 grupos. En el grupo 1 se utilizó fluoroscopia de rutina en todos los casos (n: 58). En el grupo 2 se ejecutó el mismo procedimiento sin fluoroscopia (n: 67). Posteriormente se compararon los resultados de los 2 grupos. Resultados: No hubo diferencias estadísticamente significativas entre los 2 grupos en términos de tiempo quirúrgico, tasa libre de cálculos, complicaciones, necesidad de analgésicos, requerimiento de nuevo tratamiento y escala visual analógica. Conclusión: El uso de fluoroscopia no altera la frecuencia de complicaciones ni la tasa libre de cálculos. Creemos que el uso de fluoroscopia no es indispensable en los casos en los que se consigue acceso a la pelvis renal (especialmente en procedimientos de ureteroscopia semirrígida) y que su uso debe ser limitado para evitar un aumento innecesario de exposición a la radiación


Objectives: The aim of this study was to evaluate the role of the use of fluoroscopy in patients undergoing retrograde intrarenal surgery and the effect on surgical outcomes. Material and methods: The patients who were admitted to our center with the diagnosis of kidney stones were divided into 2 groups. In group 1, routine fluoroscopy was used in all cases (n: 58). In group 2, the same procedure was performed without fluoroscopy (n: 67) and the results of the 2 groups were compared. Results: There were no statistically significant differences between the 2 groups in terms of operation time, stone-free rate, complication rate, need for analgesic and re-treatment requirement and Visual Analogic Scale score. Conclusion: The use of fluoroscopy does not alter the complication frequency and stone-free rate. We think that the use of fluoroscopy is not mandatory in cases in which renal pelvis access is achieved especially with semirigid ureteroscopy and that unnecessary fluoroscopy increases radiation exposure

RESUMO

Contexto y objetivo: La incontinencia urinaria es el efecto secundario con mayor impacto en la calidad de vida después de la prostatectomía radical. El objetivo de nuestro artículo es revisar la evidencia científica actual sobre las variaciones quirúrgicas descritas para preservar la continencia urinaria después de la prostatectomía radical. Adquisición de la evidencia: Se realizó una revisión sistemática de la literatura en PubMed, Cochrane y ScienceDirect según los criterios PRISMA (Preferred reporting items for systematic reviews and meta-analyses), utilizando los términos: urinary continence, urinary incontinence, urinary leakage, radical prostatectomy, open radical prostatectomy, laparoscopic prostatectomy, robot assisted laparoscopic prostatectomy, robotic prostatectomy y los criterios de selección PICO. Se identificaron 1.603 referencias de las que se seleccionaron 27 publicaciones que cumplieron los criterios de inclusión, 6 fueron ensayos clínicos aleatorizados y 4 metaanálisis. Síntesis de la evidencia: Las técnicas más empleadas para alcanzar una continencia urinaria precoz son la preservación del cuello vesical, de las bandeletas neurovasculares y la reconstrucción del rabdoesfínter, siendo esta la técnica con mayor evidencia, ya que existen 3 ensayos clínicos aleatorizados. Pese que algunas variaciones técnicas han conseguido mejorías en los resultados funcionales, la ausencia de consenso en la definición de incontinencia urinaria y la manera de evaluarla no permiten elaborar recomendaciones técnicas basadas en evidencia científica de calidad. Conclusiones: La reconstrucción del rabdoesfínter es la única técnica que ha demostrado mejoría en la recuperación precoz de la continencia urinaria tras la prostatectomía radical. La evidencia científica actual es heterogénea y limitada, por lo que son necesarios estudios aleatorizados bien diseñados para evaluar las modificaciones técnicas


Background and objective: Urinary incontinence is the adverse effect with more impact on patients’ quality of life after undergoing radical prostatectomy. The objective of this study is to review the present evidence that describes the variations on surgical techniques which aim to preserve urinary continence after radical prostatectomy. Evidence acquisition: We searched the literature on PubMed, Cochrane, and ScienceDirect according to the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement, using the PICO review protocol. The search terms were urinary continence, urinary incontinence, urinary leakage, radical prostatectomy, open radical prostatectomy, laparoscopic prostatectomy, robot-assisted laparoscopic prostatectomy, robotic prostatectomy. We identified 1,603 registers, and 27 articles were reviewed for meeting the inclusion criteria. Six of them are randomized clinical trials and 4 of them, meta-analysis. Evidence synthesis: The surgical techniques more frequently used to achieve early urinary continence are bladder neck and neurovascular bundles preservation, as well as the reconstruction of the rhabdosphincter. The latter has been presented in three randomized clinical trials. Even though some approaches have obtained improved functional outcomes, the lack of consensus on the definition of urinary incontinence and its measurement methods have not advocated for the creation of technical recommendations based on scientific evidence. Conclusions: The reconstruction of the rhabdosphincter is the only technique that has shown improved functional results through randomized trials. The current evidence is limited and heterogenous, and more studies with consistent criteria are needed in order to establish a standard surgical technique

RESUMO

Objetivos: Comparar los resultados oncológicos de dos técnicas quirúrgicas abiertas y dos endoscópicas para el manejo del uréter distal durante nefroureterectomía laparoscópica (NUL). Material y métodos: Revisión retrospectiva de 152 pacientes sometidos a NUL por tumor del tramo urinario superior entre 2007 y 2014. Se analizó el potencial impacto de distintas técnicas de desinserción abierta (extravesical vs. intravesical) y endoscópica (resección meato con evacuación de fragmentos vs. rodete perimeático) sobre el desarrollo de recidiva vesical, extraurotelial y supervivencia cáncer-específica (SCE). Resultados: Un total de 152 pacientes con edad media de 69,9 años (±10,1) fueron sometidos a NUL. Se reportaron 62 pTa-T1 (41%), 35 pT2 (23%) y 55 pT3-4 (36%). Treinta y dos fueron bajo grado (21,1%) y 120 alto grado (78,9%). Se realizó desinserción endoscópica en 89 casos (58,5%), 32 con resección (36%) y 57 con rodete (64%), y abierta en 63 (41,5%), 42 intravesical (66,7%) y 21 extravesical (33,3%). Con mediana de seguimiento de 32 meses (3-120), 38 pacientes (25%) desarrollaron recidiva vesical, 42 extraurotelial (27,6%) y 34 murieron por tumor (22,4%). En el análisis univariante, el tipo de técnica endoscópica no se relacionó con recidiva vesical (p = 0,961), extraurotelial (p = 0,955) ni SCE (p = 0,802). El abordaje abierto extravesical no se relacionó con recidiva vesical (p = 0,12) pero sí con aumento de recidiva extraurotelial (p = 0,045) y menor SCE (p = 0,034) respecto al intravesical. Conclusiones: El subtipo de desinserción endoscópica no influye en los resultados de la NUL. La desinserción abierta extravesical es una técnica más compleja que la intravesical y podría empeorar los resultados oncológicos


Objectives: To compare the oncological outcomes between two open surgical techniques and two endoscopic approaches for the management of the distal ureter during laparoscopic radical nephroureterectomy (LRNU). Material and methods: Retrospective review of 152 patients submitted to LRNU for the management of upper urinary tract tumors between 2007-2014. We analyzed the potential impact of two different open surgical (extravesical vs intravesical) and two endoscopic (resection of ureteral orifice and fragment removal vs endoscopic bladder cuff) techniques on the development of bladder recurrence, distant/local recurrence and cancer-specific survival (CSS). Results: A total of 152 patients with a mean age of 69.9 years (±10.1) underwent LRNU. We reported 62 pTa-T1 (41%), 35 pT2 (23%) and 55 pT3-4 (36%). Thirty-two were low grade (21.1%) and 120 high grade (78.9%). An endoscopic approach was performed in 89 cases (58.5%), 32 with resection (36%) and 57 with bladder cuff (64%), and open approach in 63 (41.5%), 42 intravesical (66.7%) and 21 extravesical (33.3%). Within a median follow-up of 32 months (3-120), 38 patients (25%) developed bladder recurrence, 42 distant/local recurrence (27.6%) and 34 died of tumor (22.4%). In the univariate analysis, the type of endoscopic technique was not related to bladder recurrence (P = .961), distant/local recurrence (P = .955) nor CSS (P = .802). The open extravesical approach was not related to bladder recurrence (P = .12) but increased distant/local recurrence (P = .045) and decreased CSS (P = .034) compared to intravesical approach. Conclusions: LRNU outcomes are not dependant on the type of endoscopic approach performed. The open extravesical approach is a more difficult technique and could worsen the oncological outcomes when compared to the intravesical

RESUMO

Objective: To establish experimental porcine model of reconstruction the neobladder by ileal seromuscular with transplantation of autologous peritoneum. Methods: This was an animal experiment carried out from January to April 2018 at animal center of Guizhou Medical University. Randomly 6 experimental female porcines were chosen, and their body weight was 28 to 33 kg. By intravenous anesthesia, the transplantation of autologous peritoneum for bladder reconstruction operation was carried out by transplanting the peritoneum onto an ileum segment which mucosa and submucosa had been removed. These flaps were used to mend and reconstruct the neobladder by suturing with edge of the detective bladder. After removal of ureteral catheters and balloon catheter at day 5 and day 7 respectively, voiding behavior was monitored, and animals were euthanized at week 12 for routine pathology, immunohistochemistry, and electron microscopic examinations. Results: Six porcines underwent reconstruction, but no one lost to complications such as peritonitis, ileus and urinary fistula. Voiding behavior was normal, and urine was clear in all animals after removal of catheters. At autopsy, reconstructed bladders were healthy. Pathological examination showed the part of reconstruction had been covered by continuous urothelium while the peritoneum disappeared and showed no ileal mucosa regrowth and residual. Scanning electron microscope showed that the transitional cells of neobladder were complete and orderly, and urothelium around suture border was continuous and no malposition. Conclusion: In this experimental porcine model, reconstruction bladder by autologous peritoneum and ileal seromuscular flaps is an ideal approach.
