Ureterocele

Ureterocele is a congenital dilation of the intravesicular portion of a ureter. In this anomaly, the part of the distal ureter that enters the bladder balloons at its opening into the bladder, forming a sac-like pouch. It appears balloon-shaped on cystoscopy. Most ureteroceles get prenatal diagnosis while doing routine antenatal Ultrasound. The ureterocele causes prenatal hydronephrosis. And, in the child, it causes frequent urinary tract infections because it is associated with vesicoureteral reflux.
