[en] Stress urinary incontinence represents an important, often unknown and, yet, certainly most unpleasant pathology. Over years, several different surgical techniques have been proposed and reported to have variable success. TVT, a simple and reproducible technique, aims at stabilizing mid-urethra, and not bladder-neck. Our own clinical experience amounts to 139 cases. All these patients were evaluated by clinical examination and, subjectively, by a questionnaire. 89.2% were cured and 6.5% improved. The most frequent complication was bladder perforation (6.5%), but it had no incidence on the final results. Morbidity was low. This revolutionary technique is very promising and our own results are similar to those reported by others.
