Ureterocele and Ureteral Duplication
Ureterocele and Ureteral Duplication What is a ureterocele? A ureterocele involves the kidney, ureter, and bladder. A normal ureter is one that transports urine from the kidney to the bladder. When a child has a ureterocele, the portion of the ureter closest to the bladder becomes enlarged because the ureter opening is very tiny and obstructs urine outflow. As the urine flow is obstructed, urine backs up in the ureter tube. What is ureteral duplication? Children who have a ureterocele may also have an u...
Urinary Tract Infections (UTI)

Umbilical Cord Care
Umbilical Cord Care The umbilical cord is the baby's lifeline to the mother during pregnancy. However, it is no longer needed once the baby is born.
