Hydronephrosis in Children

Medically reviewed by Drugs.com. Last updated on Jun 5, 2024.

Hydronephrosis is swelling in one or both of your child's kidneys caused by urine buildup. Urine normally flows from the kidneys to the bladder through tubes called ureters. A blockage in the ureters can prevent urine from flowing properly. Blocked urine flow may be caused by a narrow ureter, a kidney stone, or reflux (urine travels back up to the kidney). It may also be caused by abnormal structure of your child's kidney. Examples include a ureter that drains outside the bladder or swelling at the bottom of the ureters.
