Reviewer's report:
The aims of this retrospective, observational study were to evaluate the causes and management of OGF in
women treated at a pelvic floor centre in a developed country between January 2006 and June 2020 and to
share the practices and experience with other surgeons who care for women with urinary or fecal
incontinence due to obstetric fistulas. These goals have been met despite limitations to the study.
The manuscript is generally well written and clear with good description of surgical repair techniques
utilized. Clear presentation of the findings was included.
As pointed out by the authors, the study was limited in that the number of women treated was small, the
design was observational and retrospective, and follow-up was early in some cases. In addition, no
mention of how selection bias was avoided. 
How did the investigators assure that all cases were included?
