Abstract: ［Abstract］ Objective To investigate the effect of laparoscopic ureteroplasty in children with ureteropelvic junction stenosis. Methods 62 children with ureteropelvic junction stenosis were selected from Jiangmen People′s Hospital and the First Affiliated Hospital of Sun Yat?sen University from January 2018 to March 2019. According to the surgical plan， 31 cases were included. The control group underwent open surgery， and the observation group underwent laparoscopic pyeloplasty. The surgical indexes， complications， recurrence rate of hydronephrosis， and interleukin?6 （IL?6）， C?reactive protein （CRP） were compared between the two groups. Results The intraoperative blood loss was lower in the observation group than in the control group. The operation time， intestinal recovery and hospitalization time were shorter than the control group （P<0.05）. The incidence of complications in the observation group was 3.23% lower than that in the control group （P<0.05）. The levels of serum IL?6 and CRP in the observation group were lower than those in the control group 1 day after operation and 2 days after operation （P<0.05）. There was no significant difference in the recurrence rate of hydronephrosis between the two groups （P>0.05）. Conclusion Laparoscopic pyeloplasty for the treatment of ureteropelvic junction stenosis in children has the advantages of less trauma and quicker postoperative recovery， and it is safer.
