title: Factors influencing urinary fistula repair outcomes in developing countries: a systematic review.
abstract: We reviewed literature examining predictors of urinary fistula repair outcomes in developing country settings, including fistula and patient characteristics, and perioperative factors. We searched Medline for articles published between January 1970 and December 2010, excluding articles that were (1) case reports, cases series or contained 20 or fewer subjects; (2) focused on fistula in developed countries; and (3) did not include a statistical analysis of the association between facility or individual-level factors and surgical outcomes. Twenty articles were included; 17 were observational studies. Surgical outcomes included fistula closure, residual incontinence after closure, and any incontinence (dry vs wet). Scarring and urethral involvement were associated with poor prognosis across all outcomes. Results from randomized controlled trials examining prophylactic antibiotic use and repair outcomes were inconclusive. Few observational studies examining perioperative interventions accounted for confounding by fistula severity. We conclude that a unified, standardized evidence-base for informing clinical practice is lacking.
