[A comparative study of transcolonic and paracolic laparoscopic pyeloplasty in children with UPJO]

Comparing the laparoscopic pyeloplasty via the mesocolon and para-colonic gutter approach for the treatment of pediatric pelvi-ureteric junction obstruction (UPJO) induced simple hydronephrosis, and analyzing the potential factors influencing surgical outcomes.

Clinical data of 71 children with UPJO who underwent laparoscopic pyeloplasty at the Department of Urology of the Second Hospital of Hebei Medical University from January 2020 to January 2023 were analyzed. The patients, aged 0.25 to 18 years, were divided into two groups: 30 cases underwent the transcolonic route (mesangial group) and 41 cases underwent the transcolonic paragutter route (paragrow group).

showed that both surgical approaches had similar outcomes in terms of operation completion, smooth process, absence of laparotomy, operation time, intraoperative blood loss, postoperative feeding time, and postoperative drainage tube indwelling time, total hospitalization cost, surgical effect, and satisfaction. Common complications such as postoperative fever and abdominal pain were managed with drug treatment or observation, with no need for secondary surgery or fatal complications. Factors such as age, body mass index, preoperative symptoms, severity of hydronephrosis, and ABO blood group classification did not impact the surgical outcome.

There was no statistically significant difference between laparoscopic pyeloplasty and another surgical method in terms of various surgical outcomes for children with ureteropelvic junction obstruction. Factors such as age, body mass index, preoperative symptoms, severity of hydronephrosis, and ABO blood group classification did not have a significant impact on the surgical outcome.
