OBJECTIVE: To compare the intraoperative and immediate postoperative performance of the retropubic tension-free vaginal tape (TVT) procedure with that of the transobturator tension-free vaginal tape (TVT-O) procedure as primary treatment for female urinary stress incontinence.

METHODS: Randomized multicenter comparative trial including four university hospitals and three central hospitals in Finland. Assessment preoperatively and 2 months postoperatively included a cough stress test and the following condition-specific quality of life questionnaires: the Urinary Incontinence Severity Score (UISS), the Detrusor Instability Score, the Incontinence Impact Questionnaire-Short Form, the Urogenital Distress Inventory-Short Form, and a visual analog scale (VAS). Operation time, theater time, hospital stay, intraoperative and immediate postoperative complications were recorded.

RESULTS: Of the 273 originally randomized patients, 267 underwent the allocated operation, 136 in the TVT group and 131 in the TVT-O group. No significant differences in objective or subjective cure rates were detected. Patients in the TVT-O group had a significantly longer hospital stay, needed significantly more postoperative opiate analgesia and had significantly more complications than the patients in the TVT group. Patients in both groups had a significant postoperative improvement in quality of life, as indicated by the results of all the questionnaires used, with no difference between the groups.

CONCLUSION: The TVT and the TVT-O procedures perform equally in terms of objective and subjective cure. The statistically significant higher complication rate in the TVT-O group is not regarded as clinically significant.
