Hydronephrosis that develops before birth will often resolve on its own without kidney damage, either before or after birth. Your child's kidneys will be monitored until the swelling has gone away.
When necessary, the condition causing the back up of urine will be treated. Treatment options may include:
Medications may include:
Over-the-counter medication to reduce pain and/or fever
Antibiotics to prevent or treat infection
If the hydronephrosis is causing painful symptoms, there are signs of kidney damage, and there is a correctable lesion that will not get better on its own surgery may need to be done to allow urine to flow properly. The type of surgery that is done depends on the cause of your child's hydronephrosis. In rare cases, surgery may need to be done before birth.
There are no current guidelines to prevent hydronephrosis.
