BACKGROUND: The aim of the work is to describe an original technique of posterior musculofascial reconstruction (PMFR) during robot-assisted radical prostatectomy (RARP).
METHODS: From January 2015 to June 2016, 121 consecutives patients underwent RARP and were submitted to a novel technique of PMFR, using a single 3/0 barbed bidirectional (Filblock®, Assut Europe) suture. The first step of this new technique of PMFR, is to approximate the posterior layer of Denonvilliers fascia (DF) to the posterior part of the sphincteric apparatus. Then, the second step consists in the anastomosis of the posterior blabber neck edge with the posterior urethra edge. We realize the completion of anastomosis clockwise from 7 to 12 o’clock and anticlockwise from 5 to 12 o’clock.
RESULTS: No leakage of anastomosis was observed and the catheter was removed in the 5th day after surgery. After catheter removal, the urinary recovery of early continence at 3 days was 45% and at 7 days was 75%, while the urinary continence recovery at 1 month was 88% and at 3 months was 94%.
CONCLUSIONS: In our experience this novel approach results feasible in all patient, without extending the operation time and gives a good safety in terms of reduction of bleeding and leakage with shorter urinary continence recovery’s time. The aim of the combination of the PMFR and the vesicourethral anastomosis with one bidirectional barbed suture is to have all the advantages of both techniques plus the stability of a single running suture.
