The disorder is congenital. Children often present with severe urinary tract infections . A urinalysis may reveal blood in the urine or signs of urinary infection. In IVP may show ureterocele and hydronephrosis. An abdominal ultrasound or CT scan of the abdomen may show hydronephrosis.
Treatment is focused on relief of the obstruction.
Surgical repair of the ureterocele is usually curative. The outcome varies. If the obstruction can be cured, the damage may be temporary. However, damage to the kidney may be permanent, especially if the condition persists. The other kidney may continue to function adequately.
