URINARY TRACT FISTULAE

URINARY TRACT FISTULAE

A fistula is an abnormal or surgically made passage between a hollow or tubular organ and the body surface, or between two hollow or tubular organs. The most common cause of urinary tract fistulae in less economically developed countries is traumatic labour; in well-resourced countries, fistulae are most commonly iatrogenic, resulting from pelvic surgery (hysterectomy accounts for the majority) or radiotherapy , or they can be due to advanced pelvic malignancy , inflammatory conditions (e.g. tuberculosis [TB]), congenital disorders or foreign body erosion.
