Our aim is to present surgical technique and outcome of robotic-assisted bladder diverticulectomy (RABD). A 60-year-old patient diagnosed with bladder diverticulum in the right cranial side of his bladder underwent RABD. We inserted 6 F double J stent on the right side before the procedure. A transperitoneal approach was preferred with patient position and port placement similar to that of robotic-assisted laparoscopic radical prostatectomy. The diverticulum was expanded by filling the bladder with 100 cc of normal saline through the Foley catheter. The distended bladder diverticulum was mobilized, transacted at its neck and dissected from the surrounding tissue. The bladder and peritoneum were closed by 3/0 barbed V-Loc continuous suture.
