The long-term consequences of the hypospadias salvage repair issue.

PURPOSE: To present the long-term results of redo-hypospadias at our tertiary referral center following a failed prior repair. METHODS: One hundred sixty-four individuals with a history of unsuccessful repairs qualified for our retrospective cohort study. Our inclusion criteria were as follows: pre-operative data that was accessible, redo-hypospadias that was successfully repaired, and at least three years of follow-up at the last hospital visit. RESULTS: The mean patient age was 91.3 ± 21.1 months. The mean follow-up after successful repair was 41.3 ± 3.1 months. Ninety-two (group A) had one prior repair, and 72 (group B) had 2 or 3 repairs. Group A underwent six primary techniques: 32 underwent Onlay Island Flap (OIF), 10 underwent Mathieu, 12 underwent Tubularized Incised Plate Urethroplasty (TIPU), 8 underwent Urethral Mobilization (UM), and 34 underwent Buccal Mucosal Graft (BMG) { dorsal inlay Graft Urethroplasty (DIGU) in 4 and staged BMG in 30 patients}. In group B, four procedures were used: TIPU in 4, UM in 6, and BMG in 62 (staged BMG in 50 cases and DIGU in 12). CONCLUSIONS: The selected type of repair will depend on many factors, like residual healthy local skin and expertise. Safe techniques for repair of redo hypospadias after its 1st failure include TIPU, Mathieu, UM, OIF, and DIGU for distal varieties. After 2nd or 3rd repair DIGU, UM, and TIPU can be performed in distal types, while staged BMG can be applied for proximal ones.

Does primary urethral realignment improve the outcome of pediatric pelvic fracture urethral injury? A randomized controlled trial.

OBJECTIVE: To assess the efficacy of primary urethral realignment in the prevention of urethral stenosis and in simplifying delayed urethroplasty after complete pelvic fracture urethral injury in male children. METHODS: This randomized comparative trial included 40 boys <18 years with complete pelvic fracture urethral injury. The initial management was a primary urethral realignment in 20 boys and suprapubic cystostomy alone in the remaining 20 boys. The boys who underwent primary urethral realignment were assessed regarding the development of urethral stenosis. Boys who needed to be delayed urethroplasty in the two groups were compared regarding urethral defect length, intraoperative details, postoperative outcomes, number of procedures, and time to achieve normal voiding. RESULTS: Although 14 (70%) patients were able to void after primary urethral realignment, all of them developed urethral stenosis and needed delayed urethroplasty. No statistically significant difference between the two groups was found regarding urethral defect length, intraoperative details, and postoperative outcomes. Patients in the primary urethral realignment group underwent significantly more procedures (p < 0.001) and took a significantly longer time to achieve normal voiding (p = 0.002). CONCLUSION: Primary urethral realignment is neither able to prevent urethral stenosis nor effective in simplifying later urethroplasty after complete pelvic fracture urethral injury in male children. It exposes the patients to more surgical procedures and a prolonged clinical course.

Mini-open Anterior Pelvic Osteotomy and Spica Casting for Primary Closure of the Pelvis in Infants With Classic Bladder Exstrophy.

BACKGROUND: The objective of this study was to investigate the efficacy and safety of mini-open Salter-like anterior pelvic osteotomy followed by spica casting as an adjunct to urological reconstruction in infants with classic bladder exstrophy (CBE). METHODS: Twenty-eight infants with CBE were operated upon according to the following protocol: initial bilateral mini-open Salter-like osteotomies followed by urological reconstruction and subsequent spica casting for 3 to 4 weeks. Postoperative clinical and radiologic assessments of wound complications and union were done, respectively. During subsequent follow-ups, the foot progression angle (FPA), the interpubic (IP) distance, interischial (IS) distance, and the IS/IP ratio were measured. The Pearson correlation was used to correlate between age at the time of last follow-up, the FPA, the IP and IS distances, and the IS/IP ratio. RESULTS: The mean age at the time of operation was 5.89±0.89 months. The operative procedure took 10 to 15 minutes (mean of 12.5±1.5 min) for each side and the blood loss was negligible. Tension-free complete approximation of the symphysis was achieved in all cases. No wound complications were reported in any case. The total duration of the cast was 3.07±0.14 weeks. The mean duration of follow-up was 4.78±3.09 years. Strong positive correlation was found between the IP and IS distances ( r =0.833, P <0.0001) as well as the IS distance and age (r=0.455, P =0.015). CONCLUSION: Mini-open anterior pelvic osteotomy and spica casting may provide a minimally invasive and effective option for closure of the pelvis in infants with CBE. LEVEL OF EVIDENCE: Level IV-case series.

Penile reconstruction after complete bladder exstrophy repair.

INTRODUCTION: The decreased penile length in patients born with bladder exstrophy (BE) results partly from pubic symphysis diastasis and the separation of the corporal bodies. Also, intrinsic shortening of anterior corporal compartment, residual penile dorsal curvature, and postsurgical scarred skin share in creation of short penile length. OBJECTIVE: The goal of this study was to look at whether adult men who had bladder exstrophy (BE) surgery as babies needed and benefited from penile reconstruction, which included penile lengthening and repair of any redo penile pathology that was present at the same time. STUDY DESIGN: We reviewed the records of 31 repaired BE patients with mean age of 21.4 ± 3.7 years. The patients complained of their dissatisfaction with short penile length, residual dorsal penile curvature, distal dorsal or hypospadiac urethral opening and scared penopubic skin. The penile lengthening was performed by sub-periosteal detachment of the corporal bodies from the pubic rami in all cases. In 8 patients full thickness dermal grafts were used to penile resurfacing after its lengthening. Twelve patients underwent coronal or glanular urethroplasty. Phalloplasty was performed in one patient using forearm free graft. RESULTS: Subjective evaluation by the patient reported satisfactory results in 25/31 (80.6 %). The degree of penile lengthening measured at 6 months and one year postoperatively showed increased length which varied between 50 % and 150 % of the preoperative penile length. DISCUSSION: We hypothesize that congenital causes, such as short anterior corporeal compartment, wide pubic rami diastasis, and short penile urethra, as well as iatrogenic causes, such as post-surgical peno-pubic scars, could account for the coexisting multifactorial causes of penile shortening in male adults with BE. Penile lengthening is permitted, in our opinion, provided that the crura from the pubic rami is carefully and partially mobilized. CONCLUSIONS: The short phallus, residual dorsal chordee and distal urethroplasty can be corrected successfully in the majority of patients. Adult males with BE may have short penis that requires another reconstructive stage. The short phallus, residual chordee and distal urethroplasty can be corrected` successfully in the majority of patients.

Outcome of bilateral laparoscopic Fowler-Stephens orchidopexy for bilateral intra-abdominal testes.

INTRODUCTION: To evaluate the outcome of bilateral laparoscopic Fowler-Stephens orchidopexy (BLFSO) for bilateral intra-abdominal testes. MATERIALS AND METHODS: Prospectively, all patients with bilateral intra-abdominal testes between 2006 and 2010 were included in this study. Patients' data were analyzed for age, procedure whether single stage or staged Fowler-Stephens, intraoperative and postoperative complications, and follow up results. RESULTS: BLFSO was performed in a total of 48 testes in 24 boys with a median age of 31.6 months (range 12 to 150). All procedures were performed on an outpatient basis. Of the 24 boys, six were managed with a single stage BLFSO. The remaining 18 patients were managed with staged Fowler-Stephens orchidopexy. Testicular position after laparoscopy was the mid lower scrotum in 43 testes, the remaining five testes retracted to the inguinal canal in three (required inguinal approach for orchidopexy) and to the neck of scrotum in two. Testicular atrophy was encountered in two testes with a follow up of 18 months postoperatively. CONCLUSIONS: Outpatient single stage or staged bilateral laparoscopic Fowler-Stephens orchidopexy were successful in managing boys with bilateral intra-abdominal testes.

Long term evaluation of continence after complete primary bladder exstrophy repair.

INTRODUCTION: Continence after bladder exstrophy (BE) repair remains a major debatable challenge to pediatric urologists, together with the lack of standard definitions and long-term results in large series. OBJECTIVE: We assessed the long-term urinary continence in 142 toilet-trained cases after one (1-) stage of complete primary repair of bladder exstrophy (CPRE) and consequent procedures to achieve this goal in a single tertiary referral center. STUDY DESIGN: The current retrospective study included 123 boys and 19 girls with BE that were repaired by (1-) stage CPRE. The Mean age at (BE) repair was 9.5 ± 2.6 weeks. Complete penile disassembly (CPD) was used for epispadias repair in 42 (34.1%) and modified Cantwell-Ransley repair (MCR) was used in 81 (65.9%) boys. Bilateral anterior transverse innominate osteotomies (ATIO) were applied in all. Urinary continence was expressed in terms of the dry interval (DI). Continence procedures were afforded if CPRE failed to achieve DI ≥ 3 h (hrs.), those were in the form of endoscopic bladder neck injection (BNI), bladder neck reconstruction (BNR), and bladder neck closure (BNC) with catheterizable stoma. RESULTS: The mean age at follow up was 12.1 ± 5.2 years. DI ≥ 3 h was gained in 23 (16.2%) after CPRE alone, while complementary post-CPRE continence procedures were required to reach this goal in the remaining patients. Deflux injection was reported in 10 (7%), CIC in 8 (5.6%), BNR in 32 (22.5), and BNC with catheterizable stoma alone in 37 (26.1%), or with Charleston pouch in 32 (22.5%). DISCUSSION: We think that ≥3 h DI with voiding represents an appropriate definition of continence after BE repair. According to the results in the current series, we think that successful anatomical closure of BE is achievable, but the functional outcome in terms of continence and its evaluation is tricky. Results of continence were reported to change with age of the child, and it is difficult to evaluate both before toilet training age and long-term follow up. CONCLUSIONS: Long-term follow up of CPRE with bilateral ATIO alone or with BNI results in ≥3 h DI in a few cases; BNR after CPRE can provide a good chance for continence; otherwise, BNC with catheterizable stoma is a valid option.

Can Bcl-XL expression predict the radio sensitivity of bilharzial-related squamous bladder carcinoma? A prospective comparative study.

BACKGROUND: Local pelvic recurrence after radical cystectomy for muscle invasive bilharzial related squamous cell carcinoma accounts for 75% of treatment failures even in organ confined tumors. Despite the proven value of lymphadenectomy, up to 60% of patients undergoing cystectomy do not have it. These factors are in favor of adjuvant radiotherapy reevaluation. objectives: to evaluate the effect of adjuvant radiotherapy on disease free survival in muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder and to test the predictability of radio-sensitivity using the anti apoptotic protein Bcl-XL. METHODS: The study prospectively included 71 patients, (47 males, 24 females) with muscle invasive bilharzial related squamous cell carcinoma of the bladder (Stage pT2a-T3N0-N3M0) who underwent radical cystectomy in Assiut university hospitals between January 2005 and December 2006. Thirty eight patients received adjuvant radiotherapy to the pelvis in the dose of 50Gy/25 fractions/5 weeks (Group 1), while 33 patients did not receive adjuvant radiotherapy (group 2). Immunohistochemical characterization for bcl-xL expression was done. Follow up was done every 3 months for 12 to 36 months with a mean of 16 ± 10 months. All data were analyzed using SPSS version 16. Three years cumulative disease free survival was calculated and adjusted to Bcl-XL expression and side effects of the treatment were recorded. RESULTS: The disease free cumulative survival was 48% for group 1 and 29% for group 2 (log rank p value 0.03). The multivariate predictors of tumor recurrence were the positive Bcl-XL expression (odd ratio 41.1, 95% CI 8.4-102.3, p < 0.0001) and radiotherapy (odd ratio 0.19, 95% CI 0.05-0.78, p < 0.02). With Cox regression, the only independent multivariate predictor of radio-sensitivity was the Bcl-XL expression with odd ratio 4.6 and a p value < 0.0001. All patients tolerated the treatment with no life threatening or late complications during the period of follow up. CONCLUSIONS: Adjuvant radiotherapy for muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder has potential effectiveness and minor side effects. Moreover, Bcl-XL expression is a valuable tool for predicting those who might not respond to this adjuvant treatment.

Egyptian clinical practice guideline for kidney transplantation.

Objective: To present the first Egyptian clinical practice guideline for kidney transplantation (KT). Methods: A panel of multidisciplinary subspecialties related to KT prepared this document. The sources of information included updates of six international guidelines, and review of several relevant international and Egyptian publications. All statements were graded according to the strength of clinical practice recommendation and the level of evidence. All recommendations were discussed by the panel members who represented most of the licensed Egyptian centres practicing KT. Results: Recommendations were given on preparation, surgical techniques and surgical complications of both donors and recipients. A special emphasis was made on the recipient's journey with immunosuppression. It starts with setting the scene by covering the donor and recipient evaluations, medicolegal requirements, recipient's protective vaccines, and risk assessment. It spans desensitisation and induction strategies to surgical approach and potential complications, options of maintenance immunosuppression, updated treatment of acute rejection and chemoprophylactic protocols. It ends with monitoring for potential complications of the recipient's suppressed immunity and the short- and long-term complications of immunosuppressive drugs. It highlights the importance of individualisation of immunosuppression strategies consistent with pre-KT risk assessment. It emphasises the all-important role of anti-human leucocyte antigen antibodies, particularly the donor-specific antibodies (DSAs), in acute and chronic rejection, and eventual graft and patient survival. It addresses the place of DSAs across the recipient's journey with his/her gift of life. Conclusion: This guideline introduces the first proposed standard of good clinical practice in the field of KT in Egypt.

Acid ceramidase upregulation in prostate cancer cells confers resistance to radiation: AC inhibition, a potential radiosensitizer.

Radiation resistance in a subset of prostate tumors remains a challenge to prostate cancer radiotherapy. The current study on the effects of radiation on prostate cancer cells reveals that radiation programs an unpredicted resistance mechanism by upregulating acid ceramidase (AC). Irradiated cells demonstrated limited changes of ceramide levels while elevating levels of sphingosine and sphingosine-1-phosphate. By genetically downregulating AC with small interfering RNA (siRNA), we observed radiosensitization of cells using clonogenic and cytotoxicity assays. Conversely, AC overexpression further decreased sensitivity to radiation. We also observed that radiation-induced AC upregulation was sufficient to create cross-resistance to chemotherapy as demonstrated by decreased sensitivity to Taxol and C(6) ceramide compared to controls. Lower levels of caspase 3/7 activity were detected in cells pretreated with radiation, also indicating increased resistance. Finally, utilization of the small molecule AC inhibitor, LCL385, sensitized PPC-1 cells to radiation and significantly decreased tumor xenograft growth. These data suggest a new mechanism of cancer cell resistance to radiation, through upregulation of AC that is, in part, mediated by application of the therapy itself. An improved understanding of radiotherapy and the application of combination therapy achieved in this study offer new opportunities for the modulation of radiation effects in the treatment of cancer.

Ureteral stricture after ureteroscopy for stones: A prospective study for the incidence and risk factors.

CONTEXT: A ureteral stricture is a serious complication of ureteroscopy (URS) that was reported in the literature in highly variable rates from 0.2% to 24%. AIMS: Our aims are to estimate the incidence and to detect the risk factors of ureteral stricture after URS. SETTINGS AND DESIGN: This is a prospective, case-series study. MATERIALS AND METHODS: During the period from May 2015 to August 2016, 251 adult patients underwent 263 URS for the treatment of 304 ureteral stones. Postoperative regular follow-up was done for 12 months by ultrasound. Computed tomography urography and diuretic renogram were performed for the cases developed hydronephrosis to confirm and detect the level of the stricture. STATISTICAL ANALYSIS: IBM SPSS Statistics for Windows, Version 19.0, Armonk, NY: IBM Corp. used for data analysis. Chi-square and Fisher's exact tests were used to compare between qualitative variables. Mann-Whitney test was used to compare between two quantitative variables in case of nonparametric data. Multiple logistic regression analysis was done to measure the risk factors. P value was considered statistically significant when <0.05. RESULTS: The mean age was 43.5 years (standard deviation [SD]: ±13.6), and the mean body mass index was 28.39 (±3.96). The mean total stone burden was 12.8 mm (SD: ±5.9). Bilateral URS was performed in 12 cases. The mean operative time was 54.8 min (SD: ±22.68). Initial and final stone-free rates were 83.3% and 100%, respectively. The overall complications rate was 28.1%. Stricture occurred in four cases (1.5%). CONCLUSIONS: In our experience, the incidence of post-URS ureteral stricture is low. The impacted stone is the most common cause of URS complications and hence stricture formation.

Does the site of the orthotopic neobladder outlet matter? A prospective randomized comparative study.

BACKGROUND: To compare the results of urethral anastomosis to a button hole and to the lowest part of the anterior suture line during orthotopic neobladder substitution. METHODS: From January 2012 to December 2015, 87 consecutive male patients with invasive bladder cancer underwent radical cystectomy and Hautmann ileal neobladder. Patients were randomly divided into two groups; group I (44 patients), the outlet was created as a button-hole at the most dependent part of the pouch, group II (43 patients), the lowest 1 cm of the anterior suture line of the pouch was left open as an outlet. Patients were randomly assigned to either group using computer-generated random numbers (JMP, Version 12.0.1; SAS Institute, Cary, NC, USA) via a sealed envelope. The functional outcomes of both groups were compared especially at the urethro-enteric anastomosis. RESULTS: There were no intraoperative complications. Early postoperative complications occurred in 9 patients (5 in group I and 4 in group II, p = 0.484). Prolonged urinary leakage persisted for 11 and 14 days in 2 patients in group I and 10 and 16 days in 2 patients in group II. Delayed postoperative complications occurred in 11 patients (5 [12.5%] in group I and 6 [15.6%] in group II) (p = 0.711). Three patients developed urethro-enteric strictures (2 in group I and 1 in group II) (p = 0.571). CONCLUSION: The "non-hole" technique of urethral anastomosis was not associated with a significant increase in the complication rate when compared to the commonly performed "hole" technique.

The use of small intestinal submucosa graft for hypospadias repair: Pilot study.

OBJECTIVE: To evaluate the outcome of using commercially available (SIS) grafts for repairing hypospadias. Collagen-based acellular matrices, including SIS and bladder submucosa matrix, have been used to repair urethral strictures, with varying success, and patients with hypospadias and with inadequate or no genital skin need a substitute tissue for urethroplasty. PATIENTS AND METHODS: This pilot study included 12 patients (mean age 8 years, range 1.5-15) with hypospadias (distal in six, mid-shaft in four and proximal in two). They underwent a repair with four layers of prefabricated SIS as an onlay graft. The outcome was assessed for cosmetic appearance, urinary stream and the postvoid residual volume. The chi-squared and Mann-Whitney U-tests were used to assess the relationship between preoperative factors and the outcome of the repair with SIS grafting. RESULTS: The mean (range) follow-up was 23 (6-36) months. Nine patients ultimately voided normally, with a good cosmetic appearance and no postvoid residual urine. Six patients had a successful repair with no further intervention, whilst three had small fistulae that were treated by simple closure. In three patients the graft failed, by complete disruption or stricture. Graft infection adversely affected the outcome of SIS grafting. CONCLUSIONS: The prefabricated SIS graft can be used as an alternative substitute for urethral reconstruction when genital skin is insufficient or lacking, as in circumcised patients or a repeat hypospadias repair. Graft infection is the chief reason for graft failure and should be prevented. Further studies with more patients are needed to confirm these preliminary results.

Which type of urethroplasty in failed hypospadias repair? An 8-year follow up.

OBJECTIVE: To report our 8-year follow up for redo hypospadias repair. METHODS: A total of 56 patients with previous failed hypospadias repair were included in our study. Patients' data were analyzed regarding age, number of previous repairs, meatal location, procedure performed, operative time and complications. Patients were followed up for 3 to 102 (mean 52) months. RESULTS: Patient age ranged from 15 to 204 (mean 90.7) months. Forty-two patients had a single previous hypospadias repair, eleven had two previous repairs and three had four previous repairs. Of the 56 patients, 16 underwent oral mucosal graft urethroplasty, 15 onlay island flap, 14 parameatal flap, 10 tubularized incised plate urethroplasty, and 1 tubularized preputial flap. Complications were encountered in 16 (28.5%) patients in the form of graft contracture in 3, meatal stenosis in 2, urethral stricture in 2 including the patient with tubularized flap, urethra-cutaneous fistula in 7, bleeding in 1 and skin disruption in 1. The final complication rate was 25%. CONCLUSIONS: Decision making in redo hypospadias surgery depends mainly on local tissue availability and the degree of tissue scarring. The characteristics of oral mucosal graft make it suitable for urethroplasty in the absence of local donor tissues. A long-term follow up for redo hypospadias repair is required to assess the late neourethral stricture and residual penile curvature.

Management of calculus anuria in children: experience of 54 cases.

OBJECTIVE: To evaluate the outcome of different treatment plans for calculus anuria in children. PATIENTS AND METHODS: Patients were subdivided into three groups, A, B and C. Group A included patients who were critically ill, had serum creatinine> or =3.5mg/dl, blood urea> or =100mg/dl, serum potassium> or =7meq/l and/or blood pH< or =7.1; and they were treated initially by peritoneal dialysis. Patients in groups B and C were stable with serum creatinine<3.5mg/dl, blood urea<100mg/dl, serum potassium level<7meq/l and blood pH>7.1. In group B, the obstructing stone could not be localized, and they were treated either by percutaneous nephrostomy or JJ stent. In group C, stone level was confidently determined and patients were treated by open surgery. RESULTS: Fifty-four patients were included. All patients regained normal serum creatinine levels within 72-120h. Overall complication rate in groups A and C was 26% and 13%, respectively. In group B, overall complication rate was 66% for percutaneous nephrostomy and 50% for internal stent. CONCLUSIONS: Urinary diversion in children is associated with a high complication rate while dialysis is highly effective in children. Formal surgery in compensated children is associated with a low complication rate with good outcome and early recovery.

Bcl-XL and Bcl-2 expression in bilharzial squamous cell carcinoma of the urinary bladder: which protein is prognostic?

OBJECTIVES: Bcl-2 and Bcl-XL are the most important antiapoptotic members of the Bcl-2 family frequently overexpressed in bladder cancer. Overexpression of Bcl-XL bilharzial-related bladder cancer was associated with tumor progression. However, the negative prognostic value of Bcl-2 expression is still questionable. This work studied the expression of Bcl-XL and Bcl-2 immunohistochemically in bilharzial-related squamous cell carcinoma of the urinary bladder and determined their prognostic value in relation to recurrence after radical cystectomy. METHODS: A total of 72 patients with muscle-invasive bilharzial squamous cell carcinoma of the urinary bladder underwent radical cystectomy at our institution. The specimens were examined immunohistochemically for Bcl-XL and Bcl-2 expression. The patients were followed up for 3 years or until recurrence. The expression of Bcl-XL and Bcl-2 were related to the other prognostic indicators and patient survival. RESULTS: The expressions of both Bcl-2 and Bcl-XL were significantly different according to the grade of malignancy. Bcl-XL expression was significantly related to tumor recurrence, but Bcl-2 expression was not. CONCLUSIONS: To our knowledge, the present study is the first report of a negative prognostic value for Bcl-XL in bilharzial squamous cell carcinoma of the urinary bladder. However, this is another negative report on the prognostic value of bcl-2 in bilharzial bladder tumors.

Results of complete penile disassembly for epispadias repair in 42 patients.

PURPOSE: We evaluated the Mitchell complete penile disassembly technique for epispadias repair. MATERIALS AND METHODS: A total of 42 males 1 month to 22 years old presented for repair of epispadias between 1998 and 2002. Cases were divided into 2 groups. Group 1 included 29 cases of complete epispadias as a component of bladder exstrophy, 8 with previous continent urinary diversion. Group 2 included 13 cases of epispadias alone (10 primary and 3 secondary). Of the 29 patients in group 1, 21 underwent complete penile disassembly as part of 1-stage primary closure of bladder exstrophy. RESULTS: Mean followup was 37.5 months (range 6 to 52). Ischemic changes at the glans penis were observed in 5 cases during our initial experience. Ventral orthotopic meatus was observed in all 42 patients, conical glans in 40 (95.2%), straight shaft in 34 (81%) and urethral fistula in 1 (2.4%). There were no cases of dehiscence, meatal stenosis or urethral stricture. Erectile function was preserved in all patients. CONCLUSIONS: Complete penile disassembly is a safe procedure that can provide normalization of the urethra and penis together with satisfactory cosmetic and functional outcome.

Functional evaluation of modified T pouch as ileal neobladder orthotopic reservoir.

BACKGROUND AND OBJECTIVE: We report on the functional results of orthotopic modified T pouch ileal neobladder, incorporating serous-lined extramural ileal antireflux technique for urinary diversion after radical cystectomy. MATERIAL AND METHODS: From September 1998 through November 2001, 42 patients of mean age of 49 years (range 45-54) having invasive bladder carcinoma underwent radical cystectomy and orthotopic ileal neobladder urinary diversion, the modified T pouch. Thirty-three patients were males while the remaining 9 were females. The mean follow up was 24 months (range 18-42). Preoperative uni or bilateral ureteral dilatation was noted in 13/42 (30.9%) patients. Follow up included clinical examination, laboratory, radiological and urodynamic investigations. RESULTS: Early postoperative complications were recorded in 3 cases, that were managed conservatively. Day and night continence were achieved in 34/42 (81%) and 29/42 (69%) patients, night enuresis in 2 (4.8%), while satisfactory day and night continence were noted, respectively. Upper urinary tract (UUT) remained unchanged or improved in all cases. No need for clean intermittent catheterization (CIC). No evidence of reflux was detected. Pressure at maximum capacity (average 17 cm H2O at 600 ml). Mean flow rate was 17.6 ml/sec (range 15-24). Pelvic cancer recurrence was recorded in 5 patients at mean 24 months, respectively. CONCLUSIONS: Modified T pouch has an excellent functional criteria as an orthotopic ileal neobladder reservoir. It is absolutely indicated in short and/or massively dilated ureter.

Complete primary repair of bladder exstrophy: initial experience with 33 cases.

PURPOSE: We evaluated our initial experience with complete primary repair of bladder exstrophy in 33 children. MATERIALS AND METHODS: Between 1998 and 2001, 33 children with classic bladder exstrophy were treated with 1-stage primary repair for the first time in all except 4, who had undergone previous failed initial bladder closure. Our series included 26 boys and 7 girls with a mean age of 2 months (range 3 weeks to 14 months). The bladder was closed in continuity with the urethra and complete penile disassembly was used for epispadias repair. Anterior transverse innominate osteotomy was performed in all cases. Combined general and caudal anaesthesia were applied in all cases with an indwelling epidural caudal catheter in 7. RESULTS: Median followup was 42 months (range 24 to 62). Enterocystoplasty was needed in 3 cases during primary repair of a small bladder plate. Wound dehiscence was not recorded. Bladder neck fistula was reported in 2 children, while urethral fistula was recorded in 1 boy. Abdominal ultrasound detected no hydronephrosis in all except 3 patients. Voiding cystourethrogram showed vesicoureteral reflux in 6 patients. No loss of renal function or febrile urinary tract infection was recorded. A dry interval of 3 hours or greater was reported in 24 children (72.7%), while 9 who were incontinent of urine after failed toilet training needed other procedures to achieve continence. CONCLUSIONS: Complete primary repair with penile disassembly provides a good approach to achieve this purpose without the need for bladder neck reconstruction in some cases. Selection of the proper surgical technique together with adjunctive procedures such as osteotomy and a pain-free early postoperative period can maximize the chance of successful exstrophy repair.

Tubularized incised plate repair: functional outcome after intermediate followup.

PURPOSE: We describe the functional outcome following tubularized incised plate repair of hypospadias in toilet trained children after an intermediate followup. MATERIALS AND METHODS: Children were included in this study only if they were toilet trained and had flow rate data not less than 6 months after primary tubularized incised plate hypospadias repair or 2 months after any secondary procedure to correct complications. Uroflow data (peak flow, voided volume and post-void residuals) were analyzed and plotted on previously determined age-volume dependent nomograms. RESULTS: Of the 48 boys 39 required no secondary procedures, while 9 secondary fistula closures were performed in 2, meatotomy in 2 and dilation in 5. After either primary (26) or secondary (7) procedures 33 of the 48 patients (68.7%) had normal peak flow rate and 15 (31.3%) had low peak flow rate. Of the 48 patients 46 had post-void residual urine less than 10% of voided volume. CONCLUSIONS: Most children will void efficiently with no straining and no post-void residual (1/2) to 4 years after tubularized incised plate hypospadias repair. Of our patients 68.7% have normal peak flow rate. Intermediate followup of larger series and followup at puberty are recommended to resolve the debate concerning the long-term functional outcome of tubularized incised plate hypospadias repair.
