Hydronephrosis in Children
WHAT YOU NEED TO KNOW:
What is hydronephrosis?
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.
What are the signs and symptoms of hydronephrosis?
Your child may not have any signs and symptoms, or he may have any of the following:
- Frequent urinary tract infections
- Blood in his urine
- Dribbling urine or loss of urine control
- Pain or tenderness in his abdomen, side, or lower back
- Abdominal mass
- Nausea and vomiting
How is hydronephrosis diagnosed?
- Blood and urine tests will be used to check kidney function.
- X-rays or a CT scan may be taken of your child's kidneys, bladder, and ureters. Your child may be given contrast liquid to help the blockage show up better in the pictures. Tell the healthcare provider if your child has ever had an allergic reaction to contrast liquid.
- An ultrasound uses sound waves to show pictures of your child's kidneys and bladder on a monitor. An ultrasound may show if the kidneys are swollen or enlarged. It may also show blocked urine flow or abnormal structure.
- A voiding cystourethrogram , or VCUG, is an x-ray that will show urinary reflux. The pictures will show how well your child's bladder empties and if there is any blockage.
- A kidney scan will show how well your child's kidneys are working. This test may also show the cause of any blockage and if it is severe.
How is hydronephrosis treated?
Treatment depends on the cause of your child's nephrosis. It also depends on how severe your child's hydronephrosis is. Your child's healthcare provider may decide to wait and see if it gets better on its own. Your child may need treatment for any conditions that have caused his nephrosis. Surgery may be needed to remove a blockage so urine can drain normally. An abnormal structure may be fixed or a shunt may be placed to help widen a narrowed part of the urethra.
When should I contact my child's healthcare provider?
- Your child has a fever.
- Your child's abdomen feels full.

- Your child cannot control when he urinates and has accidents.
- Your child has low back pain or pain on one side when he urinates.
- You have questions or concerns about your child's condition or care.
When should I seek immediate care or call 911?
- Your child has severe, stabbing back pain.
- Your child has blood in his urine.
- Your child cannot urinate, or he urinates very little.
