OBJECTIVES: To determine the influence
of barbed suture in laparoscopic radical prostatectomy.
METHODS: A retrospective study of 150 patients
who underwent laparoscopic radical prostatectomy
was carried out by our department. The patients were
divided in two groups according to the kind of suture
used during the vesicourethral anastomosis: conventional
3-0 absorbable multifilament running suture (Group 1)
and bidirectional barbed suture (Quill®) (Group 2).
Operating time, postoperative urinary fistula, hospital
stay and urinary catheter duration were analysed in both
RESULTS: After the analysis of all the preoperative
variables, such as age, PSA, prostate volume, Gleason
and stage on biopsy, no statistically significant
differences were found in both groups. Operating
time was significantly shorter in Group 2 (169±43
min vs 215±45 min, p=0.00). Statistically significant
differences were found regarding postoperative urinary
fistula rate, hospital stay and urethral catheterization
duration, favourable to Group 2.
CONCLUSIONS: The use of bidirectional barbed suture
(Quill®) for vesicourethral anastomosis in laparoscopic
radical prostatectomy, when compared with the
conventional suture, shortens surgical time, reduces
urinary fistula rate, catheter duration and hospital stay,
as the anastomosis is easily performed and prevents
