Objective: 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. The median (IQR) OT was 112.5 (83.7–133.7) min and median (IQR) EBL was 25.8 (0–50) ml. The median (IQR) LOS was 7 (4.7–9.0) days. One patient (16.7%) reported early minor postoperative complication. No patient showed early or late major postoperative complications. At 2 month follow-up, all patients underwent a lower abdomen ultrasound and minimal or no postoperative PVR was found. At 6 month follow-up no LUTS were reported. Conclusions: RBD appears to be a safe treatment for posterior BD with excellent perioperative and functional outcomes. The three-dimensional visualization, greater magnification and wristed instrumentation with seven degrees of freedom allow precise dissection of BD and reconstruction of the bladder wall.

Abstract

Objective: 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. The median (IQR) OT was 112.5 (83.7–133.7) min and median (IQR) EBL was 25.8 (0–50) ml. The median (IQR) LOS was 7 (4.7–9.0) days. One patient (16.7%) reported early minor postoperative complication. No patient showed early or late major postoperative complications. At 2 month follow-up, all patients underwent a lower abdomen ultrasound and minimal or no postoperative PVR was found. At 6 month follow-up no LUTS were reported. Conclusions: RBD appears to be a safe treatment for posterior BD with excellent perioperative and functional outcomes. The three-dimensional visualization, greater magnification and wristed instrumentation with seven degrees of freedom allow precise dissection of BD and reconstruction of the bladder wall.
