Genitourinary fistula is a distressful condition involving mental, social, marital, and financial repercussions.The objective of this study is to systematically evaluate etiology, clinical presentation, diagnosis, the timing of repair, and perform a meta-analysis evaluating the success rate of various treatment modalities with respect to time taken to seek treatment.We performed a critical review of PubMed/Medline, Embase, and the Cochrane Library in April 2020 according to the PRISMA statement. Seventeen studies were included in the final analysis and all were retrospective in design.Each article was rated by the evidence-based medicine levels of evidence scale and the Methodological Index for Nonrandomized Studies scale for assessment of bias among nonrandomized studies.Of the 799 fistulae reported in 17 studies, endoscopic management was done in 35.6% (12 studies), whereas surgical management was preferred in 85.6% fistulae (15 studies). The pooled success of endoscopic stenting was 32% (95% confidence interval [CI]: 7-64) and 100% (95% CI: 98-100) in operated patients. Patients who underwent stenting within 2 weeks (20%), 2-6 weeks (21%), and6 weeks (40%) had pooled success rates of 95% (95% CI: 87-100), 46% (95% CI: 0-100), and 20% (95% CI: 1-49), respectively. Patients who underwent surgical management6 weeks (15.9%) and6 weeks (22%) of diagnosis had pooled success rates of 100% (95% CI: 99-100) and 100% (95% CI: 99-100), respectively.Stent placement as early as6 weeks (preferably 2 weeks) had better outcomes as compared to6 weeks. Proceeding to surgery regardless of timing in cases of stent failure seems to be a feasible option. |
