Sometimes the exact cause is not found.
Factors that may increase your child's chance of hematuria include: Urinary tract infectionRecent upper respiratory tract infectionFamily history of kidney problemsInjury or abuseMedications, such as certain antibiotics or pain relievers
Pelvic radiation therapy
for cancer treatment
In some cases, there may be other symptoms with hematuria. These other symptoms will depend on the underlying condition that is causing the hematuria. For example, if a urinary tract infection is the cause, your child may have to urinate often. There may also be a burning feeling during urination.
Call your child's doctor if you see blood in the urine.
You will be asked about your child’s symptoms and medical history. A physical exam will be done.
Tests to look for infections and signs of kidney trouble may include: Urine tests—tests to confirm the presence of blood and look for protein, bacteria, or cancer cells in the urineBlood tests—tests to check how well the kidneys are functioning and to look for conditions that cause hematuria
Your child's doctor may also need to look at the kidneys and urinary tract. Imaging tests may include: X-rayUltrasoundCT scanMRI scan
Other tests that may be done include: Cystoscopy—to look at the lining of the bladder
Kidney biopsy (done in rare cases)—to remove a small sample of kidney tissue for testing
Treatment will depend on the cause. Some causes do not require treatment. Other causes can be treated with medication. For example, a urinary tract infection is treated with antibiotics.
Surgery may be needed if the urinary tract is blocked.
By treating the underlying condition, the doctor may be able to prevent your child from developing hematuria.
