Abstract:
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 obstructive and 2 nonrefluxing nonobstructive. These patients had a Kalicinski folding-under remodeling of their megaureter and Cohen or Lead-better reimplantation. Success rate was 96% with only 2 failures: 1 recurrent low-grade reflux treated with subureteric Teflon injection and 1 stenosis that necessitated 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.
