Tension-free vaginal tape obturator (TVT-O) procedures for stress or mixed urinary incontinence are safe and effective long-term, investigators reported at the 2019 International Continence Society annual meeting in Gothenburg, Sweden.
Aino Warro, MD, and colleagues at Turku University Hospital in Turku, Finland, studied 106 women who underwent TVT-O surgery. Of these, 76 (72%) had stress urinary incontinence (SUI) and 30 (28%) had mixed urinary incontinence (MUI). Nineteen women (18%) previously had undergone surgery for urinary incontinence. Patients had a mean age of 57 years at the time of surgery and 66 years at the long-term follow-up visit.
After a mean time from surgery to follow-up visits of 9.25 years, the SUI and MUI groups had 89% and 73% objective cure rates, respectively, and 92% and 53% subjective cure rates, respectively. The objective and subjective cure rates were 74% and 58%, respectively, among women who underwent repeat surgery.
Clinical examination revealed that 3 (3%) patients had asymptomatic vaginal tape erosion and 3 (3%) had a post-void residual above 150 mL. In addition, 17 women (16%) reported groin pain, which was mild in 13 of them. One patient had urinary retention, and the tape was cut 3 months following surgery. She remained continent, with no reoperations for urinary continence, according to the investigators.
