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

Area of Science:

• Urology
• Gynecologic Surgery

Background:

• Stress urinary incontinence (SUI) affects many women.
• Tension-free vaginal tape (TVT) is a common surgical treatment for SUI.
• Complications, including lower urinary tract injury, can occur during TVT procedures.

Purpose of the Study:

• To investigate the incidence and risk factors of lower urinary tract injury during TVT surgery.
• To analyze preoperative morbidity and outcome results in TVT cases with lower urinary tract injury.
• To assess the impact of surgeon experience on TVT-related injuries.

Main Methods:

• Prospective enrollment of 460 women undergoing TVT for SUI.
• Data collection on incidence, morbidity, and outcomes.
• Analysis of injuries related to surgeon experience and learning curve.

Main Results:

• Lower urinary tract injury occurred in 3.9% of cases, primarily during the learning curve.
• TVT-related injuries did not increase perioperative morbidity.
• Surgical cure rates were similar with or without injury; de novo urge incontinence was slightly more common with bladder perforation.

Conclusions:

• Lower urinary tract injury during TVT is associated with surgeon inexperience.
• TVT-related lower urinary tract injury does not negatively affect medium-term outcomes.
• Careful surgical technique and experience are crucial for minimizing TVT complications.
