Hydronephrosis

Medically reviewed by Drugs.com. Last updated on May 6, 2024.

Hydronephrosis is swelling in one or both 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. Urine flow may also be prevented or slowed if your kidneys do not work correctly. Urine flows back into your urinary tract. Pressure builds up in the kidney and causes swelling.
