Abstract：Objective:To evaluate the efficacy and feasibility of laparoscopic pyeloplasty(LP)combined with nephrolithotomy associated flexible ureteroscopy(f-URS)for treatment of ureteropelvie junction obstruction(UP-JO)with nephrolithiasis in children at one stage.Methods:The clinical data of 8 patients who underwent LP and f-URS for UPJO with renal stones were retrospectively summarized from January 2013 to January 2016.There were 6 males and 2 females,5 cases of left sides and 3 cases of right sides,and all cases were unilateral.The average age was 4.5 years(3-10 years).The diagnosis of UPJO complicated with nephrolithiasis was made by ultrasonog-raphy,intravenous pyelogram(IVP),magnetic resonance urography(MRU).All patients were treated by laparo-scopic pyeloplasty combined with fiberscope nephrolithotomy at one stage.The pelvis was exposed under laparo-scopic procedure,fiberscope was taken into the opened pelvis through one trocar,and holmium laser litholapaxy was performed.Then laparoscopic pyeloplasty was performed.Results:All operations were successful,and there was no transfer to open operation.The average operation time was 98 min(85-130 min),and the average bleeding was 15 mL(10-30 mL).During the postoperative follow-up period of 3-6 months,reexaminations of renal ultra-sonography and KUB revealed that hydronephrosis regressed,the thickness of renal parenchyma increased,the stones in the pelvis and calyx were fully removed,and split renal function improved.Conclusions:The operation of laparoscopic pyeloplasty combined with fiberscope nephrolithotomy at one stage is feasible,safe,minimally inva-sive and scarless.We propose that laparoscopic pyeloplasty combined with fiberscope nephrolithotomy is potential-ly a viable treatment option for children with UPJO complicated with nephrolithiasis.
