Transobturator vaginal tape in comparison to tension-free vaginal tape: A prospective trial with a minimum 12 months follow-up.
BACKGROUND
The tension-free vaginal tape (TVT) procedure is based on the integral theory that the midurethra has an important role in the continence mechanism. Transobturator vaginal tape (TOT) is the same in concept as TVT but it differs from TVT in that, rather than passing through the retropubic space, sling materials are drawn through the obturator foramina. We prospectively compared TVT with TOT with respect to operation-related morbidity and surgical outcomes at a minimum follow up of 12 months.


METHODS
A total of 36 women with stress urinary incontinence (SUI) were alternatively assigned to the TVT group (18) or the TOT group. Preoperative evaluation included urodynamic study and I-QOL questionnaire. One year after operation the surgical result, patient satisfaction, incontinence quality-of-life questionnaire, long-term complications, and uroflowmetry were evaluated in both groups.


RESULTS
The patient characteristics in both the TVT and TOT group were similar. Mean operating time was significantly shorter in the TOT group likened to the TVT group.


CONCLUSIONS
Both the TVT and TOT procedures are minimally invasive and similar in operation-related morbidity. TOT appears to be as effective as TVT, and safer than TVT for the surgical treatment of SUI in women at 12 months follow-up.
