Vascular injury during tension-free vaginal tape procedure for stress urinary incontinence.

Background: Tension-free vaginal tape procedure is a popular surgical treatment of genuine stress urinary incontinence.
Cases: Two cases of retropubic hematoma after tension-free vaginal tape procedure are reported. One woman with an 8 x 10 cm hematoma localized to the retropubic space required transfusion of two units of packed red blood cells for symptomatic relief. Neither case required reoperation, and both patients' hematomas resolved over 6 months without treatment. Both patients were continent 9-12 months after surgery.
Conclusion: Although the tension-free vaginal tape procedure is a minimally invasive operation for stress urinary incontinence and appears to be effective, significant vascular complications can result.
