What is the time duration for developing a vesicovaginal fistula following an obstructed labour?
Correct Answer: After 1st week
Description: With dystocia, the presenting pa is firmly wedged into the pelvic inlet and does not advance for a considerable time. Tissues of the bih canal lying between the leading pa and the pelvic wall may be subjected to excessive pressure. Because of impaired circulation, necrosis may result and become evident several days after delivery as vesicovaginal, vesicocervical, or rectovaginal fistulas. In vesicovaginal fistula, dribbling of urine occurs after varying interval following delivery (5-7 days). Most often, pressure necrosis follows a very prolonged second stage.
