[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.
