Although the evaluation of surgical procedures for the repair of ureteropelvic junction obstruction continues, open pyeloplasty is still the gold standard in the management of pediatric cases. The use of stents in open pyeloplasty is subject to discussion among pediatric urologists. To clarify this question on the basis of our experience, we retrospectively reviewed our 28 stented and 15 unstented pediatric pyeloplasty operations in terms of hospital stay, early and late complications, and success rates. While there were no differences between both groups in terms of early and late complications and success rates, hospital stay favored the unstented cases. We have concluded that routine stenting in pyeloplasty is not necessary unless a perfect anastomosis is accomplished.
