Purpose: Male genitalia reconstruction in patients with exstrophy-epispadias complex often leads to secondary hypospadias, thus requiring additional surgery and resulting in possible complications. We describe a technique of male epispadias repair to prevent resultant hypospadias., Materials and Methods: The complete penile disassembly technique is modified by multiple Z-plasties, which enable creation of a funnel-like bladder neck and urethral plate lengthening. A total of 29 patients 2 months to 12 years old presenting with pure epispadias and bladder exstrophy were treated with this technique between 2004 and 2011. These patients were compared to 19 patients 1 day to 11 years old with exstrophy-epispadias treated with the standard penile disassembly technique between 2000 and 2004., Results: Outcome measures were urethral orifice position, penile length and complications. There was no statistically significant difference between the 2 groups regarding penile length or complications. In the study group the urethra reached the tip of the glans in all patients, whereas the creation of intentional hypospadias was necessary in 6 patients (31.5%) in the control group (p <0.05)., Conclusions: The modified technique was effective in obtaining appropriate meatal location without decreasing the penile length. The complication rate was not changed. Creation of resultant hypospadias at genitalia reconstruction in male epispadias should strongly be prevented., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Some patients with vesicoureteral reflux also experience voiding dysfunction. Dextranomer/hyaluronic acid copolymer (Deflux, Q-MED AB, Uppsala, Sweden) is an effective endoscopic treatment for vesicoureteral reflux. In an open label study we investigated the effect of voiding dysfunction on the efficacy of endoscopic treatment with dextranomer/hyaluronic acid copolymer in patients with vesicoureteral reflux., Materials and Methods: A total of 320 children 3 to 11 years old with grade II to IV vesicoureteral reflux confirmed by voiding cystourethrography underwent endoscopic treatment with dextranomer/hyaluronic acid copolymer. Of the patients 50 were re-treated with dextranomer/hyaluronic acid copolymer because of persistent reflux (grade II or greater). The first implantation technique was recorded on videotape. Voiding cystourethrography and micturition details were recorded at the 3 to 6-month followup visit and compared with baseline measurements., Results: At baseline 13 patients had known voiding dysfunction and 18 were misdiagnosed as not having voiding dysfunction. Of the 50 patients who required re-treatment, the initial implant was correctly positioned in 45 according to the videotape. Endoscopic observation at the time of re-treatment revealed no evidence of the implant in 15 patients. The implant was displaced in 27 patients and remained correctly positioned in 3. A total of 27 patients had voiding dysfunction, the majority of whom had urgency and frequency incontinence, had not received any anticholinergic therapy and had a displaced implant., Conclusions: Uncontrolled voiding dysfunction contributed to endoscopic treatment failure with dextranomer/hyaluronic acid copolymer in our series. Therefore, we suggest that patients with voiding dysfunction be treated at least 6 months before endoscopic therapy with anticholinergics and/or micturition rehabilitation.

Purpose: Continence is a difficult goal in exstrophy-epispadias complex repair. It is presumed that all anatomical components involved in the exstrophy-epispadias abnormality are present but laterally and anteriorly displaced. The penile disassembly technique for epispadias restores the normal anatomical relationship of the male genital components. Its extension to complete primary bladder exstrophy closure enables deeper positioning of the bladder neck within the pelvic diaphragm. We identified the perineal striated muscular complex and present its appropriate periurethral reassembly as a main step in exstrophy-epispadias complex repair., Materials and Methods: Bladder exstrophy and epispadias repairs were performed in 10 male and 3 female consecutive patients with the exstrophy-epispadias complex, including 1-stage reconstruction in 2 male newborns and 2 females with exstrophy, and as further surgery in a female with cloacal exstrophy and previous failed 1-stage repair, 4 males with incontinent epispadias (secondary repair in 1) and 4 males with epispadias in whom exstrophy closure had been previously done. In the males after bladder plate closure and corporeal body splitting a sagittal incision was made in the intersymphyseal tissue and extended posteriorly to the perineal body midline. The bipolar electrical stimulator was used to identify pelvic muscle components in the sagittal plane and reapproximate them along the tubularized posterior urethra to form the periurethral muscle complex. In the 3 females the urethral plate and vagina were similarly mobilized posterior through the sagittal incision of the perineal body. No patient underwent bladder neck plasty., Results: At 9 months to 4 years of followup cosmesis was good in 12 patients, while 1 required secondary glanular urethroplasty. There was mild pyelectasis in 3 cases but no severe hydronephrosis and no renal function deterioration. Pyelonephritis developed in 6 patients (46%). Cystography at 1 year showed that bladder capacity was 35 to 80 and 65 to 120 cc in exstrophy and epispadias cases, respectively. There was cyclic voiding with 30 to 90-minute dry intervals in 7 patients (54%), of whom 5 had exstrophy and 2 had epispadias. Daytime voiding control with a 2 to 3-hour voiding interval was achieved in 1 female with exstrophy and 2 patients with epispadias (23%). Incontinence was present in 2 patients with previous exstrophy closure and 1 with cloacal exstrophy (23%)., Conclusions: Early restoration of a physiological vesicourethral balance of coordinated activity is feasible for the progressive achievement of continence in patients with the exstrophy-epispadias complex. Sagittal splitting of the perineal tissue with identification of the muscle components as well as midline reassembly of the periurethral striated muscular complex helps to reconfigure the pelvic anatomy in a more normal fashion and allows better restoration of coordinated vesicourethral activity.

Purpose: We report our experience with the retroperitoneal laparoscopic approach for treating pediatric patients and when the percutaneous needle approach is not possible due to uncontrolled hypertension, bleeding disorders, anti-clotting medications and anatomical abnormalities., Materials and Methods: Retroperitoneal laparoscopic renal biopsy was performed in 20 patients 2 to 18 years old (mean age 9.7) during a 16-month period. At the same time 53 percutaneous needle biopsies and 1 open biopsy were performed. The child is in a flank position, and 2 trocars are used via a direct vision approach. The first trocar is 12 mm. in diameter and positioned on the posterior axillary line, and the second trocar is 5 mm. in diameter and is entered 4 cm. anteriorly. Gentle dissection is done to free the lower pole of the selected kidney, biopsy forceps are used to grasp the specimen under direct vision and the biopsy site is fulgurated using bipolar electrocautery., Results: Biopsy was performed successfully in all cases except 1, which was converted to an open procedure. Mean operative time was 40 minutes, blood loss was minimal and mean hospital stay was 1.2 days postoperatively. No pain medication was required postoperatively, and all patients returned to their usual activities within 3 to 5 days. A minor intraoperative complication, which was a peritoneal tear with no postoperative sequelae, occurred in 1 case., Conclusions: The retroperitoneal laparoscopic technique is simple and safe, and does not require extensive laparoscopic experience. We believe that this approach is reliable, and has less morbidity and several advantages compared to open surgery. It should be selected as the first choice for treating pediatric patients when percutaneous needle renal biopsy is contraindicated.

Purpose: Contralateral vesicoureteral reflux occurs after successful unilateral reflux repair in a significant proportion of patients without correlation to the surgical approach. Unilateral congenital obstructive megaureter was compared to primary vesicoureteral reflux with regard to the risk of onset of contralateral reflux after unilateral ureteral reimplantation., Materials and Methods: Unilateral congenital obstructive megaureter was diagnosed in 58 consecutive patients 2 to 10 years old (mean age 3.2). Cross-trigonal ureteroneocystostomy was performed in 57 cases and longitudinal ureteral reimplantation, according to the Politano-Leadbetter technique was done in 1. Longitudinal tapering according to Hendren was performed in 44 ureters, and the Kalicinski folding was used to repair 11 ureters. All patients underwent serial renal ultrasound, diethylenetetraminepentaacetic acid nuclear scan, excretory urogram and voiding cystourethrogram. The control group was composed of 98 age matched children with unilateral vesicoureteral reflux who underwent unilateral reimplantation with or without tapering. Fisher's exact test and Student's t test were used for statistical analysis., Results: Followup ranged from 1 to 5 years. All patients in both groups underwent a voiding cystourethrogram at 6 months, and renal ultrasound at 3, 6 and 12 months postoperatively. Grade 2 reflux developed in 1 study group patient after contralateral Kalicinski ureteral folding and cross-trigonal reimplantation (1.7%). In the control group new onset contralateral reflux developed in 11 cases (11.2%). The difference was statistically significant (p <0.005, Fisher's exact test p = 0. 033)., Conclusions: Ureteral reimplantation for unilateral congenital obstructive megaureter is not correlated with the development of contralateral reflux. The occurrence of contralateral reflux after successful unilateral reflux repair is high (11.2%), and is not correlated with age, sex and technique of reimplantation or tapering. These results support the hypothesis that the functional anatomy of the trigone is preserved in congenital obstructive megaureter but is impaired on both sides in cases of unilateral vesicoureteral reflux. The surgical management of unilateral primary vesicoureteral reflux and congenital obstructive megaureter should be differentiated based on these results.

Purpose: Contralateral vesicoureteral reflux is a well-known development after successful unilateral ureteral reimplantation that is not apparently influenced by the reimplantation technique. We sought to determine whether bilateral reimplantation should be performed routinely in unilateral cases., Materials and Methods: From 1984 to 1995 we performed contralateral ureteral meatal advancement in 53 children 1 to 9.5 years old (mean age 2.5) undergoing surgery for unilateral grades II to V vesicoureteral reflux, including 12 with reflux in duplex systems. Ureteral meatal advancement involves a transverse Y shaped mucosal incision from the nonrefluxing orifice to the opposite hemitrigone. The inferior half of the ureteral orifice is then advanced toward the midline using 3 or 4 long-term resorbable sutures. The control group included 98 children who underwent unilateral surgery for grades II to V reflux from 1990 to 1995., Results: No evidence of vesicoureteral reflux was observed in the 53 children who underwent contralateral meatal advancement. There was no obstruction or other complications. At followup contralateral reflux was found in 11 controls after unilateral reimplantation., Conclusions: Contralateral reflux has been reported in up to 27% of previously reported cases and in 11% of our control group after successful unilateral antireflux surgery. Contralateral ureteral meatal advancement has proved effective for preventing reflux in 100% of cases. It requires minimal invasion of the nonrefluxing ureter, and little additional operative time and cost.

Purpose: In 1987 we developed distal urethral advancement and glanuloplasty, a surgical technique specifically intended for coronal and subcoronal hypospadias repair that involves moving the distal urethra 0.5 to 1 cm., Y shaped meatoplasty and glanuloplasty., Materials and Methods: From January 1987 to December 1992, 271 boys 9 months to 14 years old (mean age 2.5 years) underwent repair of distal coronal and subcoronal hypospadias, including distal urethral advancement and glanuloplasty in 135 (49.8%)., Results: Long-term results in 118 cases were determined at 4 to 9 years of followup (mean 6.3). In 112 cases (95%) good functional and cosmetic results were achieved, while in 6 (5%) complications required surgical repair, including meatal stenosis in 3 (2.5%), fistulas in 2 (1.7%) and complete glanuloplasty disruption in 1. We evaluated outcomes in 19 postpubertal patients 15 to 20 years old and noted no psychological or sexual problems as a consequence of hypospadias repair., Conclusions: Long-term followup confirms the validity of distal urethral advancement and glanuloplasty for correcting a large number of coronal and subcoronal hypospadias cases.
