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. [ABSTRACT FROM AUTHOR]
