Our experience with genitourinary fistulae.

INTRODUCTION

Our objective was to analyze the incidence, etiopathology, diagnosis and therapeutic aspects of the genitourinary fistula in an Indian population.

METHODS

This is a retrospective analysis of the genitourinary fistulae repaired at the Department of Urology, Institute of Medical Sciences, Banaras Hindu University, between January 1990 and December 2006. The surgical approach varied in each patient. Interposition grafts or flaps were used as and when required. The main outcomes analyzed were the incidence, etiology, surgical approaches, accessory procedure required, need for tissue interposition, cure rate per repair and overall success rate.

RESULTS

Out of 558 cases, 403 were vesicovaginal, 84 ureterovaginal, 43 urethrovaginal and 28 vesicouterine fistulae. The most common etiology was obstructed labor (72.2%), followed by hysterectomy. The transvaginal route was preferred for repair wherever possible. The transabdominal route was adopted for the repair of supratrigonal vesicovaginal, ureterovaginal and vesicouterine fistulae and if bladder augmentation was required. Conservative management was successful in 1.9% of the vesicovaginal fistulae and in 8 cases of ureterovaginal fistula. The remaining cases were managed surgically with excellent results.

CONCLUSION

Genitourinary fistulae are not life-threatening but are socially debilitating. Surgical repair provides the definitive cure, but expectant treatment can be tried in selective patients.
