Effect of a novel technique of posterior reconstruction of pubourethralis on 'early' return of continence after robot assisted radical prostatectomy (RARP): A comparative study.

Abstract

To study the effect of a novel technique of posterior reconstruction of pubourethralis on early return of continence after robot assisted radical prostatectomy (RARP). The study included 206 patients of organ confined prostate cancer managed at our centre between March 2014 and December 2018.The patients were randomly distributed into two comparable groups with respect to age, height, weight and BMI, with 100 patients in control and 106 patients in study group. After standard excision of the specimen, the posterior reconstruction in the form of Rocco stitch was done in control group while in addition to Rocco stitch pubourethralis was approximated posteriorly in midline at the proposed site of vesicourethral anastomosis in study group. Continence was defined as the need to use 0-1 pad in 24 h. The data was collected on day 0, 3, 7, 15, 30, 90 and 180 after removal of catheter. At day zero, 3,7, 15, 30, 90 and 180 days after catheter removal continence rates (⩽1 pad usage per day) were observed to be 18.8% versus 0%, 22.6% versus 0%, 50.9% versus 5%, 72.6% versus 20%, 84.9 versus 32%, 97.1% versus 83%, and 97.1% versus 91% in the study and control group respectively. Despite small number of patients in this study the results with respect to early return of continence are encouraging in the reconstruction group and there by in favour of this technique .Furthermore the technique is easily reproducible and may be seen as one more additional step to be applied in order to enhance the recovery of continence after RARP. However it is necessary to further validate the efficacy of this procedure through multicenteric controlled trials.
