A new approach to laparoscopic implantation of the artificial urinary sphincter: Vesicovaginal approach to the bladder neck

The artificial urinary sphincter (AUS) is not used extensively in the treatment of female urinary stress incontinence (USI) due to the poor reproducibility of the techniques used. We describe a new approach to laparascopic implantation, of which dissection of the vesicovaginal space is an essential step. This enables an approach under direct vision to the posterior surface of the bladder neck.

We present two cases where this approach was used. A transperitoneal approach was made in the Trendelenburg position. The main steps were: creating the vesicovaginal space until identifying the bladder neck, creating two laterovesical spaces, communicating these with the vesicovaginal space, and dissecting the anterior surface of the bladder neck, attempting to preserve the pubovesical ligament. The cuff and reservoir were inserted through the 12mm infraumbilical trocar. The connections were externalised through a left suprapubic incision and a subcutaneous tunnel created up to the labia majora where the activation pump was placed. The procedure was completed with closure of the peritoneum. It is essential to use a vaginal valve to facilitate dissection.

Surgery time: 140 and 135minutes, with no intraoperative complications. After removing the urinary catheter, one patient had elevated postvoid residual urine volume, which was managed conservatively. Hospital stay: 72h. At 3 and 9 months the patients were fully continent.

We present the preliminary results of laparoscopic implantation of an AUS through a vesicovaginal approach to the posterior surface of the bladder neck, which might reduce potential complications that have been observed after the routine techniques.
