Transobturator versus transabdominal mid urethral slings: a multi-institutional comparison of obstructive voiding complications.

Purpose: In the last year TO slings have become an increasingly popular alternative to TA slings for the surgical treatment of SUI. Proposed advantages of the transobturator approach include improved speed, safety and the reduction of obstructive complications. We assessed outcomes of TO and TA slings in a large series of women treated at several institutions to compare the rate of obstructive complications from these procedures.
