Bladder perforation during tension-free vaginal tape surgery: does it matter?

Abstract

Objective: To analyze the incidence, possible risk factors, preoperative morbidity and outcome results in tension-free vaginal tape (TVT) cases complicated by lower urinary tract injury in a large, heterogeneous, consecutive group of women.

Study design: Four hundred sixty consecutive women who underwent TVT surgery for correction of urodynamically proven stress urinary incontinence were enrolled prospectively. All the procedures were performed at 1 center by 3 experienced surgeons.

Results: In this series, 3.9% cases of lower urinary tract injury occurred. Most of the injuries occurred during the learning curve. TVT-related urinary tract injury was not associated with increased perioperative morbidity. The cure rates were similar with and without injury. De novo urge and persistent urge incontinence were slightly more common in patients with bladder perforation.

Conclusion: Lower urinary tract injury during the TVT procedure is directly related to the inexperience of the surgeon. However, TVT-related lower urinary tract injury does not appear to affect medium-term outcome results.
