[Ectopic ureter in infancy and childhood].

Two infants, 7 children and 1 young woman have been surgically treated for ureteral ectopy in the Departments of Paediatrics and of Urology of the Medical University of Pécs over the last 15 years (1974-1989). The girl/boy ratio was 8/2. In girls, who were otherwise toilet-trained with a normal voiding pattern, constant wetting and urinary infection were the leading clinical findings. The site of ureteral drainage was the vestibule in 4 patients, the urethra in 3, the vagina in 1, the prostatic utricle in 1, and it could not be determined in 1 girl. Diagnosis was based on intravenous urography, voiding cystourethrography, ultrasonography, isotope scan, endoscopy and filling up of the bladder with a methylene blue solution. The diagnosis was more obscure when the ectopic ureter drained a poorly functioning kidney. Considering that in ectopy with duplicated system the upper pole renal segment is almost always destroyed, upper pole nephrectomy and proximal ureterectomy are advocated. In 1 neonate with esophageal atresia and tracheo-esophageal fistula ultrasonography detected the ureteral malformation. In 1 girl bilateral single ureteral ectopy was found.
