A cut or bruise on a kidney. Sometimes, the injury results in a collection of blood either in or around the kidney which causes damage to the kidney. 

Kidneys are located in the back of the abdomen and protected by back muscles and the rib cage. Due to their age and development, children have a higher chance of injuring one or both of their kidneys. 

The function of kidneys is to remove waste from the body through urine. It’s important to keep the kidneys working to keep the body in good health.

  • During a CAT scan, your child lies on a bed and slides through a machine, which gives the doctor multiple views of their stomach, including the top, side and front. 

How do specialists at Children’s Colorado make a diagnosis?

Our pediatric specialists make a diagnosis by gathering all of the information from the tests and looking at the CAT scan. Using this information, the doctor will determine if there is damage to the kidneys and determine the best treatment approach. 

How is a kidney injury treated?

Most kidney injuries are treated with bed rest 

The goal of treatment is to keep your child’s kidneys functioning and in good health. In most cases, kidney injuries are treated without surgery. Children are placed on bed rest for five to seven days until the visible blood in their urine clears up. Additionally, blood tests may be completed to monitor for internal bleeding.

Sometimes, kids need surgery

If the kidney is severely damaged, a procedure may be required to stop the bleeding. After surgery, the child stays in the hospital until the organ starts healing. Once they are discharged, your child may have limited activity for a period of time.

What to expect when you leave the hospital

Sometimes the blood in the child’s urine has not completely resolved before being discharged. In this case, the child should follow-up with his or her pediatrician every week to test for blood in the urine. 

After a child has experienced an injury to their kidney, they should have their blood pressure checked by the pediatrician at least once a year depending on the severity of the injury.
