[Relationship between type of suture and anastomotic stricture after radical prostatectomy]

We evaluated the relationship between the type of suture and occurrence of anastomotic stricture after radical retropubic prostatectomy (RRP). From April 2005 to February 2008, 48 RRP were performed. In the former 24 cases, 2-0 absorbable braided sutures were used (group A), and in the latter 24 cases, 3-0 absorbable monofilament sutures were used (group B) in the vesicourethral anastomosis. In group B, operation time was longer, blood loss was less and tumor stage was lower. While five patients in group A developed an anastomotic stricture, but no one in group B developed a stricture. Univariate analysis of the two groups revealed that only the type of suture and age were significant parameters for the anastomotic stricture.
