Urinary retention is the most common
complication to occur in the immediate postoperative period after
tension-free vaginal tape (TVT) placement. This complication can easily
be corrected by inserting a Hegar dilator or cystoscope into the urethra
with downward traction. Bladder perforation occurs in fewer than 5% of
patients undergoing placement of TVT. Urethral erosion (protrusion) of
the tape is another rare complication of this procedure.
