Transobturator tape procedure outcome: a clinical and quality of life analysis of a 1-year follow-up.

To report the results obtained with the transobturator sub-urethral tape (TOT) for the surgical treatment of stress urinary incontinence (SUI) after 1 year follow-up. Ninety-three patients diagnosed with SUI or mixed urinary incontinence (MUI) underwent a TOT procedure associated to prolapse surgery, if necessary. Pre-operative quality of life (QoL) was assessed with the Urogenital Distress Inventory Short Form (UDI-6)/Incontinence Impact Questionnaire Short Form (IIQ-7) questionnaires. Surgical and early complications were monitored. A stress test and an urodynamic test if urge incontinence de novo appeared were performed at 1 year follow-up. UDI-6/IIQ-7 questionnaires and SUI symptoms were recorded. Patients' characteristics, pre-operative quality of life and urodynamic evaluation were similar in the TOT and in the pelvic floor surgery group. From the sample, 15% had post-operative retention and 10% had vaginal erosion. The global rate of objective cure was 97% in both groups. The scores of the QoL questionnaires were worse by 9% and 10% with the procedure, respectively. Patients with urodynamic (MUI) or persistence of SUI symptoms (10%) did not reach a significant improvement, although patients with urge incontinence de novo (10%) did. The TOT procedure is safe and effective. Results showed that the association to pelvic floor surgical techniques did not diminish 1 year later. The stress test outcome assessment can overestimate the results, compared to the QoL assessment. In our report, the MUI did not improve with this surgical approach. Our results highlight the necessary employment of both the objective testing and the patient's opinion of her symptoms during daily life.
