[Anderson-Hynes pyeloplasty in children under 2 years. Is the laparoscopy the technique of choice?].

OBJECTIVE To analyze if the laparoscopic pyeloplasty is as effective as the open procedure in the ureteropelvic junction obstruction in patients under 2 years of age. PATIENTS AND METHODS Pyeloplasties performed in children under 2 years of age between 2007 and 2010. Weight, pre and postoperative renal pelvis and calices diameter, operating time, hospital stay and complications were analyzed. RESULTS We found no statistic differences in weight, complications, or pre and postoperative renal pelvis and calices diameter. However, we found differences in hospital stay and operating time (p<0.05). CONCLUSIONS Laparoscopic pyeloplasty in children under 2 years of age is a good alternative technique for ureteropelvic junction obstruction, although operating time are still long.
