Robotic-assisted bladder diverticulectomy: point of technique to identify the diverticulum

We aim to outline our technique of performing a robotic-assisted bladder diverticulectomy at our institution and report our surgical outcomes. We report the cases of three robotic-assisted bladder diverticulectomies, performed at the Royal Surrey County Hospital during the period of January 2014 to December 2015. Patient was positioned in low dorsal lithotomy position. A 6Fr double-J stent was prophylactically inserted at the start of the procedure. Foley catheter was placed over guide wire into the diverticulum and balloon inflated on the diverticulum neck. We used a transperitoneal extravesical approach to mobilise the distended bladder diverticulum, dissected en bloc and transected at the diverticulum neck in all cases. The bladder was closed in two layers with absorbable sutures. The procedures were uneventful, without post-operative complications and minimal blood loss. The median length of stay was 3 days and all three patients reported a significant improvement in all symptoms with non-significant post-void residuals. Robotic-assisted bladder diverticulectomy is a safe and effective procedure that results in both symptom relief and minimal post-void residuals.
