Obstructive Uropathy and Ectopic Ureterocele on Renal Imaging

摘要

Ectopic ureteroceles are diagnosed with increasing frequency, usually in patients in infancy or early childhood. Unlike the simple ureteroceles, they are almost always associated with the upper segment of a duplex kidney. Scintigraphy with Tc-99m chelates demonstrates hydronephrosis and hydroureter. A ureterocele is rarely demonstrated in the bladder through scintigraphy (1). A case of marked hydronephrosis of the upper pole and a ureterocele in the bladder revealed on renal imaging is presented.
