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.
