Transvesical bladder diverticulectomy via bladder neck opening during robot-assisted radical prostatectomy.

INTRODUCTION

As bladder diverticula in older adults are often secondary to bladder outlet obstruction, bladder diverticulectomy is often performed with prostate treatment. Cases of sequentially performed robot-assisted bladder diverticulectomy and prostatectomy have been reported; however, performing cystotomy for each procedure may increase the risk of complications and prolong operative time.

MATERIALS AND SURGICAL TECHNIQUE: We reported the cases of three patients who underwent diverticulectomy without additional cystotomy via the bladder opening during robot-assisted laparoscopic radical prostatectomy in our hospital.

DISCUSSION: This technique corresponds to a transvesical approach through the bladder neck opening. Hence, it is especially useful for well-visualized diverticula close to the ureteral orifice or on the posterior wall. Although other approaches may be better depending on the location of the diverticulum, it is considered a reasonable approach that does not require an additional cystotomy.
