ureterocele
Pronunciation: yoo-REE-ter-oh-seel
Cystic dilatation of the distal ureter within the bladder, often associated with duplicated collecting systems.
Full Definition
A ureterocele is a congenital anomaly characterized by cystic dilatation of the terminal ureter as it enters the bladder. The condition results from incomplete dissolution of the ureteral membrane during fetal development, creating a balloon-like structure within the bladder. Ureteroceles are classified as either simple (intravesical) or ectopic, with ectopic ureteroceles being more common in children and frequently associated with complete ureteral duplication. The condition can cause urinary obstruction, vesicoureteral reflux, and increased risk of urinary tract infections. Treatment options range from endoscopic incision to complex surgical reconstruction, depending on the anatomy and associated complications.
Usage
Usage note: Specify whether simple or ectopic, and note association with ureteral duplication when present.
