RELATIONSHIP BETWEEN ANASTOMOTIC STRICTURE AND TYPE OF SUTURE AFTER RADICAL PROSTATECTOMY
stricture of the vesicourethral anastomosis remains a well-documented complication after radical prostatectomy, it’s occurs in 0,5 to 32% of man after radical prostatectomy. We evaluate the relationship between anastomotic stricture and type of suture.
from 2008 al 2011 we looked incidence of anastomotic strictures in 210 patients randomized in two groups: in 110 patients we performed vesicourethral interrupted anastomosis with 3-0 absorbable braided suture (group A), in 100 patients with 3-0 absorbable monofilament suture (group B).
Al patients performed neck sparing radical prostatectomy.
There were no significant differences in two groups, in age, Gleason score, nerve-sparing status, intraoperative blood loss, degree of extravasation on initial cystography, or duration of the indwelling urinary catheter. While 9 patients (8,1%) developed an anastomotic stricture in group A, but no one in group B developed a stricture (P< 0,01). In 6 patients (56%), the bladder neck stricture occurred within 3 months after surgery, in 3 (28%) at 4-12 months after surgery and in nobody more than 12 months after surgery. Probably absorbable braided suture could be induce a flogistic reaction and conseguentely an anastomotic stricture. Conclusions: From 2012 we performed vesicourethral interrupted anastomosis with 3-0 absorbable monofilament suture in all patients and no one developed a stricture. In our experiences the type of suture is significant parameter for the anastomotic stricture. ==fine abstract==
