Unilateral Ureterocele.

This video shows Unilateral Ureterocele. A ureterocele appears as a cystic structure projecting into the bladder, often near the normal location of the vesicoureteric junction (VUJ). A ureterocele is a birth defect that affects the kidney, ureters (the tubes that carry urine from the kidneys to the bladder), and bladder. A ureterocele blocks the flow of urine which causes swelling at the bottom of the affected ureter. Ureteroceles are often diagnosed by prenatal ultrasound where a dilated ureter and kidney (or upper part of a kidney) and a cystic structure (the ureterocele) in the bladder are seen. Ureteroceles can also be found by ultrasound after a child has a urinary tract infection or other reason to obtain a renal ultrasound. Ureteroceles are birth defects that occur in approximately 1 out of every 2,000 babies. They occur most often in Caucasians. A ureterocele is 10 times more common in girls than in boys because a duplex collecting system (two ureters for one kidney) is more common in girls. Ectopic (extravesical) ureterocele refers to ureteroceles with tissue that originates at the bladder neck or beyond, into the urethra. They typically arise from the upper pole moiety of a duplicated collecting system and are more common in the pediatric population. A ureterocele is a swelling at the bottom of one of the ureters. Ureters are the tubes that carry urine from the kidney to the bladder. The swollen area can block urine flow. A ureterocele is a birth defect. In most cases, urethrocele does not cause serious health problems. But it may cause you to leak urine. You may notice this when you cough, laugh or jump. You may also have problems emptying your bladder. In most cases, if there is reflux up the ureter into the lower part of the kidney, the reflux should be treated. It is unlikely to disappear with time. If this is the case, removal of the ureterocele and ureteral re-implantation (recreation of the flap valve) is recommended. A ureterocele usually occurs in the lower part of the ureter, where the ureter enters the bladder. Ureteroceles are equally common in both left- and right-side ureters. Some persons with ureteroceles are asymptomatic. Often, the diagnosis is made later in life due to kidney stones. Ureteroceles are cystic dilatations of the distal ureter that occur due to congenital ureteric wall weakness. They can be orthotopic, occurring in normal ureteric locations and most commonly seen in adults. It is simply a swelling limited to the end of the ureter as it enters the bladder. The swelling resembles a balloon on ultrasound or during a camera examination. Radiographically ureterocele appears as a round, constant filling defect at the ureteral orifice. Ureteroceles appear as transonic intravesical lesions on ultrasonic demonstration of the bladder, producing a 'cyst within a cyst' appearance. In most cases, urethrocele does not cause serious health problems. But it may cause you to leak urine. You may notice this when you cough, laugh or jump. You may also have problems emptying your bladder. In most cases, if there is reflux up the ureter into the lower part of the kidney, the reflux should be treated. It is unlikely to disappear with time. If this is the case, removal of the ureterocele and ureteral re-implantation (recreation of the flap valve) is recommended.
