We reviewed literature examining predictors of urinary fistula repair outcomes in developing country settings, including fistula and patient characteristics, and peri-operative 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 following 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 peri-operative interventions accounted for confounding by fistula severity. We conclude that a unified, standardized evidence-base for informing clinical practice is lacking.

“…Schistosoma hematobium mainly infests the urinary system but can also affect the genitalia. Infestation of the bladder wall with bilharzia ova can interfere with the normal process of healing after surgery (1). In this report we present a patient in whom vaginal schistosomiasis is likely to have contributed to the impaired healing of a vaginal tear after delivery.…”

ObjectiveTo assess the association between chronic schistosomiasis infection, determined by bladder biopsies, and vesicovaginal (VVF) repair outcomes at an urban hospital in Angola. Other objectives were to quantify the prevalence of chronic schistosomiasis among patients with VVF and to assess agreement between pelvic X‐rays and bladder biopsies for chronic schistosomiasis diagnosis.MethodsIn this retrospective chart review, data were collected on patients who underwent VVF repair between 1 June 2022 and 30 November 2022 including: age, number of previous fistula repairs, Goh classification of fistula, X‐ray and biopsy results, fistula repair outcome, perioperative complications and postoperative incontinence. Age and number of previous repairs were described using means with standard deviations. Goh classification, X‐ray and biopsy results, fistula repair outcome, perioperative complications, and postoperative incontinence were described using frequencies. Parametric and nonparametric tests and Cohen's κ were calculated using R software and Excel.ResultsOf the 76 charts retrieved, 60 met inclusion criteria. The overall fistula repair failure rate was 26.7% (n = 16). There was no difference in the fistula repair failure rate between those with (26.9%) and without (26.5%) evidence of chronic schistosomiasis infection (χ2 = 2.33 e‐31, 95% confidence interval [CI]: −0.30, 0.28). The prevalence of chronic schistosomiasis was 43.3%. There was no agreement between X‐ray and biopsy in diagnosing chronic schistosomiasis infection (Cohen's κ = 0.23, 95% CI: −0.001, 0.47).ConclusionThere was no difference in the chance of fistula repair failure between those with evidence of chronic schistosomiasis infection and those without.
