    Abstract:
    UNLABELLED: Objetive: Pelvicureteric junction (PUJ) obstruction is the main cause of hydronephrosis in childhood. Open pyeloplasty has been the gold standard treatment of this condition with success rate above 90%. The role of laparoscopic pyeloplasty (LP) in children is less well defined and has slowly emerged as an alternative procedure. We report outcomes of our initial experience with LP in 38 children from 2 months of age. MATERIALS AND METHODS: From June 2015 to December 2017 38 children aged 2-60 months (mean age 1.7 years) underwent LP for correction of PUJ obstruction. The mean pre operative anteroposterior diameter of the renal pelvis (APD) was 43,5mm and all patients had hydronephrosis (APD 21.4-76 mm) and obstructed curve on diuretic renogram. Anderson-Hynes pyeloplasty was the performed technique. Results are reported. RESULTS: Mean operative time was 107 minutes (70-180) with no conversion to open procedure. Pain control was needed mainly in the fi rst 12hs. Mean hospitalization was 2 days (1-5). There were complications in 5 children not affecting the fi nal outcome. Two patients had a re-obstruction requiring a second procedure with good result. The mean follow up was 18 months (13-36). The mean reduction on the postoperative APD was 41% - p<0,001 (end APD 5 to 41mm). Overall success rate was 94,7%. All children had good cosmetic results. CONCLUSIONS: This is a small series limited by short follow up, however its data suggest that LP has good functional and cosmetic results, not compromising the success of the open procedure, regardless patient age.
