Doctor! will I be dry? factors determining recurrence after vesicovaginal fistula repair
To evaluate various prognostic factors which determine outcome after surgical repair of vesicovaginal fistula.
The retrospective study was conducted at Koohi Goth Fistula Hospital, Karachi, and comprised data related to patients having undergone vesicovaginal fistula repair from January 2007 to June 2012. Multivariate analysis of the record was done using SPSS 19 software determining odds ratio with 95% confidence interval.
Record of 640 patients were analysed with an overall success in 558(87.2%) cases. Multivariate analysis determined that the recurrence of vesicovaginal fistula was significantly related to multiplicity (9-fold recurrence risk), pre-operative size (10-fold recurrence risk for fistula >2cm compared to0.05 each) prognostic factors for recurrence.
Successful surgical repair of vesicovaginal fistula require careful evaluation of various factors, including number, size, previous attempts to surgical repair and duration of fistula.
