The surgical outcome of total urogenital mobilization for cloacal repair

J Urol. 2007 Apr;177(4):1492-5. doi: 10.1016/j.juro.2006.11.055.


Purpose: Total urogenital mobilization is deemed to preserve the urogenital sinus blood supply and avoid ischemic complications. We report our experience with this technique for cloacal repair.

Materials and methods: We retrospectively reviewed all consecutive cases of persistent cloaca managed by total urogenital mobilization via a posterior sagittal approach by a single pediatric urologist between 1998 and 2003. During this period 22 girls (12 with a common channel longer than 3 cm) underwent total urogenital mobilization for cloaca repair (1 redo) at a median age of 10 months (range 2 to 102). A total of 15 procedures (68%) could be completed by a perineal approach only. Four patients with a long common channel required additional maneuvers after mobilization to complete the reconstruction.

Results: Urethral stenosis was observed in 2 patients after urethral separation from the vagina (1) and common channel retubularization (1). One child with a perineal hemangioma required a redo posterior sagittal anorectoplasty for complete vaginal and anal closure. In addition, 1 case of urethrovaginal fistula was diagnosed on cystovaginoscopy but was asymptomatic, and 1 child with a minor residual common channel underwent urethral revision to allow easier intermittent catheterization. With a median followup of 48 months (range 11 to 162) the latest examination involving endoscopy with anesthesia showed a good result in 17 patients, a tight introitus that might require further surgery in 3 and a minimal residual common channel of 0.5 cm in 2.

Conclusions: Total urogenital mobilization is an effective technique for repairing short and long common channels, and a low surgical complication rate can be anticipated.
