Laparoscopic and robot-assisted continent urinary diversions (Mitrofanoff and Yang-Monti conduits) in a consecutive series of 15 adult patients: the Saint Augustin technique.

OBJECTIVE

To present a series of 15 laparoscopic and robot-assisted Mitrofanoff and Yang-Monti vesicostomies in an adult population, and to assess the feasibility and safety of these minimally invasive approaches.

PATIENTS AND METHODS

Between 2009 and 2012, 15 patients underwent laparoscopic (n = 11) or robot-assisted (n = 4) construction of vesicostomy by a single surgeon (D.R.): Mitrofanoff appendicovesicostomy (n = 11) or double Yang-Monti ileal conduit (n = 4). Fourteen patients underwent concomitant augmentation enterocystoplasty. Indications for surgery included neurogenic bladder (n = 11) and urethral dysfunction (n = 4). The patients were evaluated postoperatively using cystography. Quality of life (QoL) was evaluated using an internally developed questionnaire.

RESULTS

All surgeries were successfully completed with no conversions. Operating time was always <5 h. The mean estimated blood loss was 150 mL and the mean follow-up was 22 months. Early postoperative complications included deep retrovesical abscess (n = 2) and upper urinary tract infections (n = 4), and one patient had peri-operative cardiac failure. Late postoperative complications included stomal stenosis (n = 2), persistent low-pressure bladder incontinence (n = 1) and recurrent infections (n = 1). Surgical excision of the conduit was necessary in one patient. Postoperatively, patients showed complete bladder emptying and no leak on follow-up cystography. According to our QoL questionnaire, 13/15 patients did not regret the surgery.

CONCLUSIONS

While a longer follow-up is needed to assess the durability of our results, this series shows that the laparoscopic and robot-assisted approaches for the construction of continent urinary diversions are feasible and safe in an adult population.
