Abstract: Objective To discuss the efficacy of retroperitoneal laparoscopic dismembered pyeloplasty for pediatric ureteropelvic junction obstruction(UPJO). Methods Retroperitoneal laparoscopic dismembered pyeloplasty was performed on 24 patients with UPJO.The age of the patients ranged from 3 to 14 years(mean,7 years).The diagnosis was set up by ultrasonography,IVU,CT or magnetic resonance urography.All the patients had hydronephrosis,with 4 cases mild,10 cases moderate and 10 severe ones. Results All operations were completed laparoscopieally,without conversions to open surgery during operation.The mean operative time was 180 min(range 150 to 200).The mean blood loss was 60 ml(range 40 to 100)and the mean postoperative hospital stay was 7 d (range 5 to 9).All 24 patients were followed-up for 6 to 24 months(mean,1 4 months).There was no stricture at UPJ.Eighteen patients had complete resolution of hydronephrosis and 6 patients showed obvious alleviation in hydronephrosis. Conclusion Retroperitoneal laparoseopie dismembered pyeloplasty could be a mini-invasive,safe,and effective procedure for the treatment of UPJO in pediatric patients.
