    Abstract:
    OBJECTIVES: To determine the feasibility of vesicourethral anastomosis using running suture during retropubic radical prostatectomy and to compare the surgical outcomes of vesicourethral anastomosis using running suture with those of the standard interrupted suture technique. METHODS: A total of 60 patients undergoing radical prostatectomy from 2010 to 2012 at the Yamaguchi University Hospital, Japan were included in the present study, and were randomly assigned to vesicourethral anastomosis using running suture (n = 30 patients) or a standard interrupted suture technique group (n = 30 patients). Vesicourethral anastomosis using running suture was carried out with 12-bite sutures using 3-0 poliglecaprone. The primary end-point was the time to catheter removal. Patients' health-related quality of life was assessed using the Expanded Prostate Cancer Index Composite in 56 patients (28 patients in each group). RESULTS: No significant difference was found in the median suturing time between the two study groups (both 19 min, P = 0.449). The time to catheter removal was significantly better in the vesicourethral anastomosis using running suture group (hazard ratio 5.23, 95% confidence interval 1.73-17.65, P = 0.003). The pad-free rate was significantly higher in the vesicourethral anastomosis using running suture group at 1 month after surgery (20.7% vs 3.3%, P = 0.0463); however, there was no significant difference at 3 months and beyond. The Expanded Prostate Cancer Index Composite urinary and bowel summary scores at 1 month were significantly better in the vesicourethral anastomosis using running suture patients (both P < 0.01), though no significant difference was observed thereafter. A vesicourethral anastomosis stricture was noted in three patients (10%) in the standard interrupted suture technique group, and none in the vesicourethral anastomosis using running suture group. CONCLUSION: Running suture for vesicourethral anastomosis is feasible during retropubic radical prostatectomy. Furthermore, it offers better outcomes than the conventional standard interrupted suture technique, with a higher likelihood of improvement in patients' health-related quality of life.
