Background: The aim of this report is to describe our surgical technique for robot-assisted laparoscopic bladder diverticulectomy. In this technique, methylene blue is instilled into the bladder to aid in intra-abdominal identification of the diverticular neck. Subjects and Methods: We retrospectively reviewed the records of patients who underwent robot-assisted bladder diverticulectomy by a single surgeon. Results: Between September 2008 and January 2011, 5 patients successfully underwent robot-assisted laparoscopic bladder diverticulectomy using 1% intravesical methylene blue. All cases were completed without intraoperative complication or need for open conversion. Mean operative time was 216 minutes, with a mean estimated blood loss of 45 mL. Patients were discharged 1-2 days following surgery. No patient experienced a perioperative complication. Conclusions: The robot-assisted approach for bladder diverticulectomy is a viable alternative to both open and laparoscopic surgery. The use of intravesical methylene blue greatly aids in identification of the diverticular neck during this procedure.
