Purpose: Urinary continence is the goal of exstrophy-epispadias complex (EEC) reconstruction. Patients may require a continent urinary diversion (CUD) if they are a poor candidate for bladder neck reconstruction or are receiving an augmentation cystoplasty (AC) or neobladder (NB). This study was designed to identify the incidence of surgical complications among various bowel segments typically used for CUD.
Methods: A prospectively kept database of 1078 patients with EEC at a tertiary referral center from 1980 to 2012 was reviewed for major genitourinary reconstruction. Patient demographics, surgical indications, perioperative complications, and outcomes were recorded.
Results: Among reviewed EEC patients, 134 underwent CUD (81 male, 53 female). Concomitant AC was performed in 106 patients and NB in 11. Median follow up time after initial diversion was 5 years. The most common CUD bowel segments were appendix and ileum. The most common surgical complications after CUD were small bowel obstruction, post-operative ileus, and intraabdominal abscess. There was a significantly increased risk in the occurrence of pelvic or abdominal abscess when colon was used as a conduit compared to all other bowel segments (OR=16.7, 95% CI: 1.16-239) and following NB creation compared to AC (OR=39.4, 95% CI: 3.66-423). At postoperative follow-up, 98% of patients were continent of urine via their stoma.
Conclusion: We report the largest series to date examining CUD in the EEC population. The increased risk of abdominal and pelvic abscesses in patients who receive a colon CUD and undergo NB compared to AC indicates that while surgical complications following major genitourinary reconstruction are rare, they do occur. Practitioners must be wary of potential complications that are best managed by a multi-disciplinary team approach.
