A case of Prolapsed Ureterocele / 대한비뇨기과학회지

ABSTRACT

Ureteral duplication is the most common developmental abnormality of the urinary tract. The ureter which is originated from upper segment of kidney is often associated with a ureterocele and the lower ureter, the vesicoureteral reflux. An ureterocele is a sacculation of the terminal portion of the ureter. On the base of location of the orifice, ureterocele is classified into simple and ectopic type. The simple ureterocele has normally located ureteral orifice and is more commonly found in adults than in children and relatively small in size. The ectopic ureterocele is found in the bladder neck or urethra and is protruded external meatus, seldomly, and can produce infravesical obstruction. We treated prolapsed huge ureterocele in 10 month old female with pyelopyelostomy. And in follow up study, the ureterocele was not found in radiologic study and urinary tract infection was eradicated.
