ureterocele
Pronunciation: yur-EE-ter-oh-seel
A cystic dilation of the distal ureter that protrudes into the bladder, often causing obstruction.
Full Definition
A ureterocele is a congenital anomaly characterized by cystic dilation of the terminal portion of the ureter as it enters the bladder. The dilated segment creates a balloon-like structure that can obstruct urine flow and may be associated with duplicated collecting systems. Ureteroceles can be classified as simple (intravesical) or ectopic, with ectopic ureteroceles extending beyond the bladder neck. Treatment typically involves endoscopic incision or surgical excision depending on the type and associated complications.
Usage
Usage note: Often confused with urethrocele; ensure correct anatomical reference to ureter versus urethra.
