[Complete ureteric duplication associated with ureterocele: two cases report].

Herein we report two cases of complete ureteric duplication associated with ureterocele. A 4-month-old girl with non-visualizing left kidney was hospitalized with complaints of cloudy urine and fever. An antegrade left pyelogram revealed a completely duplicated collecting system; a duplex tortuous ureter, and round radiolucent filling defect in the bladder. Under the diagnosis of completely duplicated ureter associated with the upper pole ureterocele, ureterocystoneostomy was performed. A circumferential incision was made around the base of the ureterocele and the Politano-Leadbetter technique was employed. Her postoperative course was uneventful. However, an excretory urogram showed a mild hydronephrotic upper pole. A 1-year and 4-month-old girl with the history of repeated urinary tract infections and fever attacks was admitted. The excretory urogram showed a left hydronephrotic lower pole with a "drooping flower" and no opacification of the upper pole. A radiolucent filling defect was seen in the bladder. A left antegrade pyelogram demonstrated the massively dilated upper pole with a hydroureter terminating in the ureterocele. Left heminephrectomy with partial ureterectomy was performed and left hydronephrosis and hydroureter with an atrophic kidney were seen. The postoperative course was uneventful.
