Robotic bladder diverticulectomy: step-by-step extravesical posterior approach – technique and outcomes

AbstractObjective: The aim of this study was to evaluate the feasibility of robotic extravesical posterior surgical bladder diverticulectomy for treatment of symptomatic bladder diverticula (BD).Materials and methods: Data from patients with posterior BD who consecutively underwent robotic bladder diverticulectomy (RBD) from 2013 to 2016 in Azienda Ospedaliera Universitaria Integrata, Verona, were retrospectively reviewed. Baseline characteristics, perioperative outcomes including operative time (OT), estimated blood loss (EBL), postoperative transfusion rate and length of hospital stay (LOS), and early (30 days) and late (90 days) postoperative complications were recorded and analysed.Results: Six patients underwent RBD. Storage, voiding and postvoiding lower urinary tract symptoms (LUTS) were reported by 33.3%, 100% and 33.3% of patients, respectively. The median [interquartile range (IQR)] BD diameter was 7.1 (5.5–9.5) cm; median (IQR) preoperative postvoiding residual volume (PVR) was 300 (90–395) ml....
