The efficacy of STRATAFIX® spiral PDS for vesicourethral anastomosis during robot-assisted laparoscopic radical prostatectomy: a single-center retrospective study.

PURPOSE: To investigate the efficacy of continuous suturing using barbed suture for vesicourethral anastomosis (VUA) during robot-assisted laparoscopic radical prostatectomy (RARP).

MATERIALS AND

METHODS

Seventy-three consecutive patients who underwent RARP by a single surgeon between 2020 and 2022 were retrospectively divided based on the suture type used for VUA: group A, 3-0 poliglecaprone-25 RB-1 needle (Monocryl®), n = 46; group B, 3-0 spiral polydioxanone (PDS) barbed suture with RB-1 needle (STRATAFIX®), n = 27.

RESULTS

There was no significant difference in patient background characteristics between groups, including age, body mass index, and clinical stage. However, group B had a significantly shorter operative time, console time, hospital stay, and duration of urethral catheterization. The VUA time was significantly shorter in group B than in group A (17.9 min vs. 10.6 min; p < 0.001). Only 1 case of minor leakage was observed during the intraoperative leak test (1 patient in group A). There was no significant difference in the number of pads used at 1, 3, 6 months and 1 year postoperatively. There were no urethral strictures, and there was no significant difference in pathologic results or postoperative prostate-specific antigen progression between groups.

CONCLUSIONS

Our study suggests that the use of barbed suture during VUA for RARP is associated with reduced VUA time.
