Stepwise Description and Outcomes of Bladder Neck Sparing Robot-Assisted Simple Prostatectomy.

To present a stepwise description and outcomes of bladder neck sparing (BNS) robot-assisted simple prostatectomy (RASP). Between March 2015 and December 2018, 30 consecutive patients with benign prostate hyperplasia underwent BNS RASP. Baseline characteristics, and intraoperative and postoperative variables were retrospectively abstracted. Descriptive statistics were used to report the variables. The median age was 66.5 (59.3-72.3) years, and median body mass index was 27.6 (24.5-72.3) kg/m. The median preoperative International Prostate Symptoms Score was 23 (17.5-27), and median prostate size was 97 (74-148.75) mL. The mean (standard deviation [SD]) operative time was 107.5 (22.2) minutes, and the mean (SD) estimated blood loss was 132.4 (35.4) mL. All cases were completed robotically without any intraoperative complications, and continuous bladder irrigation was not necessary for any patient postoperatively. All patients were able to void after catheter removal except one patient with a preexisting diagnosis of neurogenic bladder who resumed clean intermittent catheterization. All patients were continent as defined as using 0 pads postoperatively. Of the 19 patients who had antegrade ejaculation before the operation, 8 patients (42%) reported of continued antegrade ejaculation after the operation. In this report, we demonstrate a simplified approach of BNS RASP that is reproducible with a favorable perioperative complication rates and acceptable postoperative functional outcomes. This technique obviates the need for continuous bladder irrigation and intraperitoneal drain.
