The Kalicinski ureteral folding technique for megaureter in children. Experience in 23 cases

We report our series of 16 children with 23 megaureters: 7 were refluxing, 11 were obstructive (7 primary and 4 secondary), 3 both refluxing and obstr uctive and 2 nonrefluxing nonobstructive. These patients had a Kalicinski f olding-under remodeling of their megaureter and Cohen or Lead-better reimpl antation. Success rate was 96 % with only 2 failures: 1 recurrent low-grade reflux treated with subureteric Teflon injection and 1 stenosis that neces sitated reoperation. Kalicinski's technique with Cohen type reimplantation is one of the best alternatives for megaureters, mainly because it does not present the disadvantages of the excisional procedure.
