A Comparison of Continuous and Interrupted Suturing in Laparoscopic Pyeloplasty

Abstract

Background:Laparoscopic pyeloplasty is one of the most common reconstructive procedures performed by urologists. Both continuous and interrupted sutures are being practiced for ureteropelvic anastomosis. The success rate and the complications associated with the suturing technique needs evaluation. We analyzed the results from of our patients who underwent laparoscopic pyeloplasty using both techniques.Objective:To review the outcome differences among patients undergoing laparoscopic pyeloplasty regarding suturing technique.Materials and Methods:All patients who underwent laparoscopic, transperitoneal dismembered pyeloplasty of the primary pelviureteric obstruction were analyzed. The primary outcome was successful pyeloplasty, as assessed by the resolution of symptoms and T½ <10 minutes. The secondary outcomes were the complication rate and the operative parameters. The difference in the parameters was assessed by Student t test analysis.Results:Of the 107 patients we studied, 65 had interrupted suturing and 42 had continuous suturing. The success rate was not significantly different among the 2 groups. The mean suturing time, postoperative drainage volume, postoperative hospital stay, and total cost of the procedure were significantly less in the continuous suturing group.Conclusion:The continuous suturing technique is preferred over the interrupted suturing technique for laparoscopic pyeloplasty because the success rates are equal and the postoperative stay, suturing time, drain output, and cost of the procedure are better.

“…Running suture is usually faster and associated with a lower leakage rate [17,18]. But it also raises concerns for a higher incidence of stricture [19].…”

Robotic surgery in pediatric urology: Current status

“…We perform ureteropelvic anastomoses with 6‐0 PDS® II (Johnson & Johnson K.K., Tokyo, Japan) running sutures . The running suture is preferred over the interrupted suture for LP because the success rates are equal and because the postoperative stay, suturing time, drain output, and cost are better . In RP, the surgical outcomes between interrupted and continuous suture groups have been reported to be the same .…”

Retrospective comparison of outcomes of laparoscopic pyeloplasty using barbed suture versus nonbarbed suture: A single-center experience

“…The most important, time-intensive, and also the most difficult part of LP is intracorporeal suturing and knotting for ureteropelvic anastomosis. [5678] In conventional LP, ureteropelvic anastomosis is done using polyglactin (vicryl) or polydioxanone in continuous or interrupted manner. Ureteropelvic anastomosis using the continuous suturing technique has a comparable success rate with that using interrupted suturing.…”

“…Various methods have been invented in the past to simplify the process of suturing and knot tying such as knot pushers, suture clips, and pretied sutures. [5678]…”
