Comparative analysis of suturing technique in pediatric pyeloplasty on surgical outcomes

Abstract

Purpose: Pyeloplasty for ureteropelvic junction obstruction is the gold standard for surgical repair. There are currently no reports outlining optimal suturing technique. This paper compares the effect of suturing technique in dismembered pediatric pyeloplasty (open and laparoscopic) on post-operative outcomes.

Methods: A non-concurrent cohort study assessed different suturing techniques in both open and laparoscopic dismembered pyeloplasty performed two senior urologists at a tertiary referral pediatric center. Cases were stratified according to different suturing techniques for ureteropelvic anastomosis and subgroup analysis was performed according to open or laparoscopic approach.

Results: A total of 185 renal units were evaluated. The overall comparative analysis of different anastomotic suturing techniques and clustered analysis according to open and laparoscopic approach showed no significant differences on post-operative complication rate, leakage, stenosis, redo-pyeloplasties, operative time and hospital stay. There was a significant difference between suturing techniques on stent duration, age and weight of the patient. There was no effect of suture type or size on post-operative complication rate, leakage, UPJ stenosis and redo pyeloplasty rates, however, sample sizes were small.

Conclusion: Suturing technique has no significant effect on the surgical outcomes assessed regardless of open or laparoscopic technique.
