[TVT and TOT: a comparison between these two techniques based on our clinical experience]

A retrospective evaluation and a comparison of results from two minimally invasive surgery techniques that we adopted for the treatment of SUI. MATERIALS AND METHODS. In this study we evaluated 113 selected patients who underwent SUI minimally invasive surgery from 1-1-2000 to 31-12-2007. 87 patients underwent epidural anesthesia. 26 local anesthesia. In Group A (TVT) 61 patients were enrolled, mean age 57.6 (±22). 43 patients (70%) were on menopause. In Group B (TOT out-in) 52 patients were enrolled (for 34 of them we used the Obtape® sling while for 18 the Obtryx® one), their mean age was 58.5 (±20.5) and 39 patients (75%) were on menopause. Patients from both groups did not undergo any past previous urogynecological surgery and suffered from stress urinary incontinence with cervico-urethral hypermobility butno other associated pathology. The pre-operative work-up included an evaluation of patients based on ICS guidelines. RESULTS. Group A (TVT) - mean follow-up 66.3 months, dry patients 53/61 (86.8%). Bladder perforations resolved by catheterization 3/61 (5%). Transient voiding dysfunction 14/61 (22.8%). "De novo" urgency 8/61 (13%). One patient on self-catheterization due to persistent urinary retention underwent a single-side section of the sling with spontaneous micturition and complete continence recovery. Group B (TOT out-in) - mean follow-up 35.5 months, dry patients 43/52 (82%). 4 patients (7.6%) complained oftransient voiding dysfunction, 5 patients (9.5%) for "de novo" urgency, 1 patient underwent a sling removal due to vaginal erosion 4 months after surgery (Obtape®).
