Hydronephrosis: Causes, Risks, and What You Need to Know

When hydronephrosis, a condition where urine builds up in the kidney due to a blockage, causing swelling and potential damage. Also known as kidney swelling, it doesn’t happen on its own—it’s always a sign something else is wrong with how urine moves out of the body.
