Hydronephrosis

Skilled Kidney Care for Kids

When urine is blocked and can’t drain from the bladder to the kidneys, one or both kidneys can swell. This condition, called “hydronephrosis,” can cause infection or kidney damage. A baby may be born with hydronephrosis, but it can happen at any age. It usually goes away on its own. But if your child needs more advanced treatment, our highly experienced team at Nemours can care for even the most complex cases.

Services We Offer to Treat Hydronephrosis

Services We Offer to Treat Hydronephrosis


Pediatric urologists at Nemours treat children of all ages with hydronephrosis. Our teams develop a care plan that’s just right for your child’s condition. Our care, which may vary depending on the location and which doctor your child sees, may include:

  • advanced diagnostics to tell us how the bladder and kidney are functioning, including voiding cystourethrogram (VCUG) (X-ray imaging of the bladder using contrast dye inserted through a tiny tube when the bladder is full to examine it as it empties) or a kidney scan (imaging using a small amount of radioactive material inserted into a vein) 
  • close monitoring, including advanced ultrasounds before and after birth
  • antibiotics to prevent or treat infection
  • surgery to repair severe cases of urinary tract blockage, including minimally invasive techniques that use small cuts for faster healing, less pain and scarring, and fewer risks
