Clinical classification of vesicouterine fistula

Objectives and Methods: The aim of this paper is to propose a classification of vesicouterine fistula based on the routes of menstrual flow. Results: Three types of the fistula are distinguished: type I — with menouria; type II — with dual flow via both the bladder and vagina; and type III — with normal vaginal menses. Conclusions: There is relevance of such division to both diagnosis and treatment. The simplicity and clinical utility of this classification warrant its widespread use.
