OBJECTIVE: To compare two transobturator suburethral tapes (Obtape, Mentor-Porges and TVT-O, Gynaecare, Johnson and Johnson) used in the management of urodynamic stress incontinence (USI), for tape erosion (vaginal/urethral) rates, clinical presentation, management and outcome. PATIENTS AND METHODS: We retrospectively studied women who underwent a transobturator suburethral tension-free vaginal tape (TVT) procedure for managing USI in a tertiary referral centre in the West of Scotland over a 36-month period. In our department, the transobturator approach has been the first-choice approach for TVTs since July 2003. Two types of tapes were mainly used, Obtape and TVT-O, and the choice of tape was primarily decided by the surgeons' preference. RESULTS: In all, 316 women had a transobturator tape procedure, of which 96 were associated with another procedure; 112 women had TVT-O using the 'inside-out' technique and 204 had the 'outside-in' technique. Of the latter, 192 had Obtape, four had Obtryx (Boston Scientific) and eight had Monarc (American Medical Systems Inc.) tapes. Sixteen women developed vaginal tape erosion, and significantly more were in the Obtape group than in the TVT-O group (7.29% vs 1.78%, P = 0.038). The patients' age, body mass index, previous vaginal surgery and concomitant vaginal surgery were not significant risk factors for erosions. The time between surgery and diagnosis of erosion was 1-45 weeks, with only one patient being asymptomatic; all others presented with clinical symptoms such as vaginal bleeding, discharge and dyspareunia. Thirteen patients were continent at presentation and 10 of these remained continent after surgical management. In the TVT-O group the erosions were in the lateral vaginal wall, while in the Obtape group the erosions were in the form of central tape extrusion secondary to defective vaginal wall healing. CONCLUSION: There were significantly more vaginal tape erosions in the Obtape group than in the TVT-O group. No cases of urethral erosions were identified.
