Comparison Of Suture Material For Vesico-Urethral Anastomosis In Robotic Radical Prostatectomy

Introduction The aim of this study was to compare outcomes after vesicourethral anastomosis (VUA) with barbed suture (BS) and non-barbed monofilament suture (NBS) in robot-assisted laparoscopic radical prostatectomy (RALRP) in a match - pairs design.Material and methods Medical recordings of 385 consecutive patients with prostate carcinoma have been evaluated, and 70 patients who have undergone RALRP-BS were compared with 70 patients with RALRP-NBS in a matched - pairs design. Preoperative clinical parameters (age, prostate-specific antigen, clinical stage, Gleason score of the prostate biopsy, and prostate volume) and operative data (operation, docking, console, posterior reconstruction (PR), anastomosis times, duration of catheter, length of hospital stay, estimated blood loss, time to perform the anastomosis and its quality) were evaluated, as well as postoperative parameters (pathological stage, Gleason score, specimen weight, follow-up duration, biochemical recurrence, complication rates, and duration of postoperative analgesic treatment).Results No statistically significant difference was found for pre-operative parameters between the two groups. Although, anastomosis time, quality of anastomosis, duration of urethral catheter and total anesthesia time were significantly less in the RALRP-BS group than in the RALRP-NBS group (P <0.01). Other peri- and postoperative parameters were not statistically significant between the two groups. Pathological data and the follow-up period and complication rates were similar between the two groups.Conclusions This study showed that, RALRP-BS is a safe, efficient and cost-effective PR and VUA during RALRP than compared with RALRP-NBS. Shorter anastomosis time, operative time and posterior reconstruction time, while it may be equivalent with regard to estimated blood loss (EBL), catheterization time and early continence rates at 4-6 weeks.
