Prevention Of Urethral Retraction With Stay Sutures (PURS) During Robot Assisted Radical Prostatectomy Improves Early Urinary Control: A Prospective Cohort Study

To evaluate early continence rates with a novel modified vesico-urethral anastomosis technique based on prevention of urethral retraction using anastomosis sutures as stay sutures (PURS) during robot-assisted radical prostatectomy.

The modified anastomosis technique was used in 60 patients and data collected prospectively. This cohort was compared with another consecutive 60 patients operated with standard anastomosis technique. This new technique is based on preventing urethral retraction of the posterior urethra with 2 anastomosis sutures being used as stay sutures. The outcomes were prospectively followed and groups compared regarding early continence. International Consultation on Incontinence Questionnaire Short Form (ICIQSF) was used to assess incontinence and its impact on the quality of life. Pad use (yes or no pads) was evaluated as a more stringent criterion.

Preoperative patient characteristics were similar between the two groups. Anastomosis was completed faster in PURS group (15.1 vs. 18.5 min, p=0.05). At postoperative week 1 and month 1, the severity and bother of incontinence was significantly less in the PURS group (12.7 vs. 4.1 and 10.1 vs. 2.6, p<0.001). PURS cohort reported significantly superior pad-free rates at both postoperative month 1 (73% vs. 35%, p<0.0001) and month 3 (83% vs. 53%, p=0.0004) On multivariable analysis, younger age and the new anastomosis technique were two independent predictors to improve early continence. Four patients in modified anastomosis group (4/60) and 1 in standard anastomosis group (1/60) necessitated temporary urethral recatheterization due to urinary retention.

We describe a simple and time efficient modified urethrovesical anastomosis technique by using anastomosis sutures as stay sutures to prevent perineal retraction of the urethral stump. Our results demonstrated that the technique is an independent factor impacting on early recovery of urinary continence. Future randomized controlled studies would be required to further test the reproducibility of this technique.
