Horseshoe Kidney

Key Points about Horseshoe Kidney (Renal Fusion)

  • Horseshoe kidney is when the two kidneys join (fuse) together at the bottom. They form a 'U' shape like a horseshoe. It is also known as renal fusion.
  • The condition occurs when a baby is growing in the womb, as the baby’s kidneys move into place. Horseshoe kidney can occur alone or with other disorders.
  • Researchers aren’t sure exactly why horseshoe kidney occurs. It may be caused by a problem with chromosomes. Horseshoe kidney can occur along with some genetic disorders, such as Turner syndrome and Edward syndrome.
  • About 1 out of 3 children with horseshoe kidney will have a problem with the heart and blood vessels, nervous system or genitourinary system.
  • The condition can’t be changed or cured. But a child with no symptoms may not need any treatment. If your child has symptoms or related problems, those will be treated.
  • A child with horseshoe kidney is more at risk of kidney injury. A child with horseshoe kidney may not be able to play contact sports.
