Additional four cases of infants and children have been treated at our hospital since April 1977. In this article, age, sex, symptoms at onset, radiological findings, histology of the removed kidney and operative procedures were mentioned. The ectopic orifice opens at the bladder neck in 14 caces (35.8%), at urethra in 15 (38.5%), and at external urethral meatus in 2 (5.1%), and the blind endnig ureter was seen in 3 cases (7.7%). Complete duplex collecting system was seen in 37 of 39 patients (94.9%). The other two had the single dysplastic kidney. Thirty-three patients (84.6%) were younger than 6 years of age at presentation. Thirty-four patients were female and 5 male. Twenty cases had the left, 15 the right and 1 the bilateral EUC. Pathological examination showed dysplastic change in 23 of resected kidneys (88.5%) with pyelonephritic change.
