Ultrasonic evaluation of simple and ectopic ureteroceles.
Ureteroceles appear as transonic intravesical lesions on ultrasonic demonstration of the bladder, producing a 'cyst within a cyst' appearance. Four patients, three with simple ureteroceles and one with an ectopic ureterocele were investigated by intravenous urography (IVU), ultrasound (US) and cystoscopy. Two patients had bilateral simple ureteroceles with non-dilated ureters and two had unilateral ureteroceles, one simple, and one ectopic with a hydroureter. Previously ultrasonography of the fluid-filled bladder has demonstrated only large ureteroceles. The present study was successful in demonstrating both large and small ureteroceles.
