Treatment results of 74 secondary megaureters in 48 children (25 males and 23 females with one segmental and 73 total megaureters) are presented. The left side prevailed over the right one (ratio 1.4:1.0); the lesion was bilateral in 54%. Forty-two children (88%) were treated surgically. Eleven megaureters (15%) were modelled. and 2 megaureters had to be reoperated. The follow-up period ranged between 7 months and 9.5 years. Urinary infection was reduced from 80 to 54%, chronical renal failure was reduced from 65 to 54%, and the occurrence of arterial hypertension remained unchanged. Excellent results were achieved in 27%, they were satisfactory in 60% and poor in 13% of the megaureters.
