Robot-assisted laparoscopic bladder diverticulectomy combined with photoselective vaporization of prostate: a case report and review of literature.

摘要

PURPOSE: Open surgery, endoscopic technique, and standard laparoscopic technique are surgical options for the management of bladder diverticuli. In this article, we report robot-assisted bladder diverticulectomy (RABD) and photoselective vaporization of prostate (PVP) in the same patient sequentially. To the best of our knowledge, this is the first case report of RABD combined with PVP. MATERIALS AND METHODS: A 63-year-old patient with benign prostatic hyperplasia and a secondary large bladder diverticulum underwent sequential PVP and RABD. Cystoscopic examination revealed obstructing prostate lobes and a large diverticulum at posterior wall of bladder. After completion of PVP procedure, a 16F urethral catheter was inserted into the diverticulum via outer sheath of optic urethrotome and another 16F urethral catheter was left in bladder for urinary drainage. A transperitoneal approach was preferred. The diverticulum was distended with saline infusion via the Foley catheter inside the diverticulum. The distended diverticulum was seen easily and dissected from the surrounding tissue. The bladder was closed in two separate layers. RESULTS: Total operative time, including diverticulectomy with PVP procedure, was 230 minutes, and console time was 90 minutes. The length of stay was 7 days. CONCLUSIONS: There has been always concern about the high intravesical pressures secondary to irrigant instillation that may disrupt the bladder repair. To avoid this problem we combined robotic diverticulectomy with PVP. Because of hemostatic properties of potassium-titanyl-phosphate laser, we did not encounter with bleeding after prostatectomy procedure. Moreover, we did not use irrigation, and the suture line of the bladder was kept safe. Therefore, we recommend to use greenlight laser in combined prostate and RABD operations. RABD is a feasible and safe procedure. RABD and PVP can be performed safely in the same patient sequentially.
