ABSTRACT
Ectopic ureter accounts with an incidence of 1 in 2000 newborns. When present, ectopic ureter can be associated with duplex kidneys in an 85 % of the cases. Clinical manifestations of this malformation include incontinence and urinary tract infections. Ectopic ureter frequently occurs in association with a dysplastic upper pole renal moiety. When a poorly functioning upper pole segment is present, a standard surgical treatment is upper pole heminephrectomy. A 23-years old woman presented with left renal colic pain, fever and urinary leak. Ultrasound, intravenous pyelogram and antegrade pyelogram revealed a partial duplex right kidney and a complete duplex left kidney with hydronephrosis and ectopic insertion into the urethra of the left upper pole moiety. Following diagnosis upper pole heminephrectomy and partial ureterectomy was performed.
