Bladder exstrophy: staged reconstruction.

View original source ↗Export metadata ↓

Abstract

The modern staged approach to bladder exstrophy reconstruction has undergone significant changes since it was first advocated by Jeffs and Cendron in the 1970s. Although varied surgical approaches have been tried in the bladder exstrophy condition, the staged approach to bladder exstrophy repair has withstood the test of time. Progress continues to be made in evaluating the outcome of older types of staged reconstruction, with continuing modification and improvements in the modern approach to staged reconstruction. This treatise will update the reader on recent advances in the treatment of bladder and cloacal exstrophy.

Bilateral anterior pubic osteotomy in bladder exstrophy repair: report of increasing success.

Bilateral posterior iliac osteotomy is performed in most patients undergoing primary closure of an exstrophic bladder; the aims are to facilitate abdominal-wall closure, prevent postoperative wound dehiscene, and possibly, to achieve better urinary control in older age. A new technique, anterior pelvic osteotomy of the superior pubic ramus, seems to obtain tension-free symphysis approximation safely and quickly. We report our initial experience with this osteotomy. Five neonates, four males and one female from 1 to 4 days old, all underwent closure surgery for bladder exstrophy (BE) and subsequent bilateral osteotomy of the superior pubic ramus (SPRO). Postoperatively, Bryant's traction was applied. Tension-free, complete approximation of the symphysis and uncomplicated healing were achieved in all five cases without palsy of the obturator nerve or postoperative hemorrhage. Follow-up revealed partial rediastasis with a stable anterior pelvic ring. Tension-free closure and immobilization are important factors in both initial and subsequent closure of BE. Several osteotomy techniques are currently in use. SPRO presents numerous advantages, namely, ease and rapidity, minimal blood loss, and no requirement for an extra skin incision or need to turn the patient on the operating table. A certain degree of rediastasis with growth was subsequently observed: although undesirable, this complication is common to all osteotomy techniques. We believe that SPRO is a valid and uncomplicated method to facilitate BE closure.

A population based analysis of continence outcomes and bladder exstrophy.

PURPOSE: Whereas the literature on bladder exstrophy is replete with outcomes of specific continence surgical procedures in highly select patients, there are no data on the outcomes related to continence for a complete exstrophy population, which is more comprehensive with respect to a variety of surgical procedures performed to achieve continence. To provide urologists and patients with an overview of potential continence outcomes devoid of any selection bias, we report on a comprehensive exstrophy population, focusing on the various procedures required for urinary continence. MATERIALS AND METHODS: We reviewed the charts of all patients with bladder and cloacal exstrophy who underwent a staged repair to achieve urinary continence at a single institution between 1988 and 1998. Urinary continence was then correlated to the types of surgical procedures, and subgroup analysis for predictors of urinary continence was performed. The type of bladder neck reconstruction allowed subgrouping cases into group 1-bladder neck reconstruction only, group 2-bladder neck reconstruction with augmentation and/or appendicovesicostomy and group 3-bladder neck closure. RESULTS: Of the 43 patients identified 26 were male, 4 had cloacal exstrophy and 3 had complex exstrophy variants with ectopic hindgut and spina bifida. Groups 1 to 3 comprised 9, 15 and 19 patients with urinary continence rates of 56%, 67% and 100%, respectively. The age at which patients became continent was delayed in groups 2 and 3 (8.2 and 8.7 years, respectively) compared to group 1 (4.8). Of all the potential variants measured gender was the strongest predictor of continence with 94% of females versus 69% of males achieving it. Of the males those with (57%) compared to those without (83%) a history of bladder neck stenosis or paraexstrophy flaps had worse continence. Repeat bladder neck reconstruction was only successful in 23% of patients. CONCLUSIONS: All patients can be rendered continent but many may achieve this successful outcome by other procedures following initial bladder neck reconstruction. When managing failed bladder neck reconstruction, the type of surgical repair chosen may need to address the need for enhanced bladder storage and the issue of potential bladder augmentation. The advances made in the treatment of the epispadiac urethra may now facilitate clean intermittent catheterization. Earlier recognition of the need for adjunctive storage procedures in addition to bladder neck reconstruction may facilitate the timing of providing enhanced continence, independence and self-esteem, and do so with fewer operative procedures. We speculate that the current complete urethral and bladder repair in newborns will add further to the storage functions of the native bladder tissues and improve the potential of achieving more effective bladder outlet control.
