[A comparative study between two procedures of TVT retropubic mid-urethral sling placement for treatment of female stress urinary incontinence]. / Étude comparative entre deux procédures de mise en place d'une bandelette sous-urétrale rétropubienne TVT dans le traitement de l'incontinence urinaire d'effort féminine.

OBJECTIVE: To evaluate complications and functional outcomes at 1 year and more of a modified Tension-free Vaginal Tape (TVT) technique from that of classic TVT. PATIENTS AND METHODS: Retrospective study comparing the two techniques. For the modified TVT technique, a peri-urethrovesical hydrodissection was performed. An 18-gauge hollow needle, in which a thread was introduced, was used as an ancillary for the placement of the sling. The sling was secured to the thread and then positioned with it. Bladder filling objectified perforations. An absorbable suture around the sling allowed its descent if necessary. RESULTS: One hundred and eighteen procedures were performed (54 classic TVT and 64 modified TVT). For the standard TVT and the modified TVT, the vesico-urethral perforation rates were respectively 7.4% and 1.5% (P<0.05), those of reoperations for pulling the sling downward 11.1% and 1.5% (P<0.05). A 1 year and more, healing and satisfaction rates were respectively 83.3% and 79.2% for the standard TVT versus 88.2% and 90% for the modified TVT (NS). The dissatisfaction rate was lower for the modified TVT (P<0.05). CONCLUSION: By modifying the placement of the classic TVT, it is possible to reduce its complications while maintaining its efficacy.
