Abstract Objective: To study the effect of laparoscopic dismembered pyeloplasty (LDP) on perioperative indexes, postoperative complications and prognosis in children with hydronephrosis caused by ureteropelvic junction obstruction (UPJO). Methods: A retrospective analysis was conducted. 190 children with hydronephrosis caused by UPJO diagnosed and treated in the hospital between September 2016 and September 2019 were selected by convenience sampling. They were divided into the study group (106 cases) and the control group (84 cases) according to the operation methods. The former were treated with LDP and the latter were treated with open pyeloplasty. Observe and compare the perioperative indicators and postoperative complications of the two groups, and evaluate the renal morphology and renal function of the children after surgery. Results: The operation time of the study group was longer than that of the control group. The intraoperative blood loss, length of hospital stay and the dosage of analgesics were less or shorter than those of the control group (P<0.05). The incidence of postoperative complications was significantly lower than that of the control group (5.66% vs 14.19%, P<0.05). The thickness of renal parenchyma and glomerular filtration rates (GFR) in the two groups were increased, while the renal volume and serum creatinine (Scr) levels were decreased in 6 months after operation. Besides, the increase or decrease in study group was greater than that in the control group at 3 months after operation (P<0.05). However, there was no significant difference between the two groups at 6 months after operation (P>0.05). Conclusion: LDP is safe and effective in the treatment of children with hydronephrosis caused by UPJO. It can reduce the intraoperative blood loss and postoperative complications, promote postoperative recovery of renal morphology and renal function, and improve the prognosis.
