Robot-assisted Supratrigonal Cystectomy and Augmentation Cystoplasty with Totally Intracorporeal Reconstruction in Neurourological Patients: Technique Description and Preliminary Results.

Abstract

Augmentation cystoplasty as a third-line therapy for neurogenic detrusor overactivity performed by an open approach has long been studied. Few laparoscopic and robot-assisted series have been reported. To evaluate the feasibility, safety, and functional outcomes of completely intracorporeal robot-assisted supratrigonal cystectomy and augmentation cystoplasty (RASCAC) in patients with refractory neurogenic detrusor overactivity. We identified all patients undergoing RASCAC, as treatment for refractory neurogenic detrusor overactivity, from August 2016 to April 2018. RASCAC was performed in all cases using a standardized technique with the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) in a four-arm configuration. Perioperative data, and functional and urodynamic results at 1-yr follow-up were assessed. Statistical analysis was performed using Stata version 15.1. Ten patients were identified. No conversion to open surgery was needed. The median operative time was 250 (interquartile range 210-268) min, the median estimated blood loss was 75 (50-255) ml, and the median hospitalization time was 12 (10.5-13) d. The 30-d major complication rate was 10%. Two patients presented a late urinary fistula; in one of the cases, surgical revision was needed. In both cases, low compliance to intermittent self-catheterization was identified. At 1-yr follow-up, functional and urodynamic outcomes were excellent. Robot-assisted augmentation cystoplasty has been shown to be safe and feasible, with a reasonable operative time and low complication rate in experienced hands. A higher number of patients and longer follow-up are, however, warranted to draw definitive conclusions. In this report, we look at the outcomes of robot-assisted supratrigonal cystectomy and augmentation cystoplasty in neurourological patients. Perioperative, functional, and urodynamic results are promising. Further studies with a longer follow-up are needed to confirm these findings.
