Can Kidney Stones Cause Blood in the Urine?

Yes, kidney stones can cause blood in the urine, a condition known as hematuria. As a stone moves through the kidney or ureter, its hard or jagged surface can irritate the urinary tract, resulting in bleeding. The blood may be visible, making urine appear pink, red, or brown, or it may only be detected through a urine test.

Why Do Kidney Stones Cause Blood in Urine?

Kidney stones form when certain minerals and substances in urine become concentrated and form hard crystals. When a stone moves or becomes lodged in the urinary tract, it can irritate the surrounding tissue and cause bleeding. This is one of the recognized symptoms of Kidney Stone Disease.

Blood in the urine may occur alongside other symptoms, including:

• Sharp pain in the back, side, abdomen, or groin
• Pain or burning while urinating
• Frequent urge to urinate
• Nausea or vomiting
• Cloudy or foul-smelling urine

However, blood in the urine does not always mean you have a kidney stone. Urinary infections, kidney conditions, certain medications, and other urinary tract problems can also cause hematuria. Therefore, unexplained blood in the urine should be medically evaluated.

How Is the Cause Diagnosed?

A doctor may begin with your medical history, physical examination, and a urine test to look for blood or signs of infection. Depending on your symptoms, additional tests such as ultrasound or CT imaging may be recommended to identify the size and location of a stone or investigate other possible causes.

When Should You Seek Medical Attention?

Blood in the urine should not simply be assumed to be caused by a stone. Seek prompt medical evaluation, particularly if bleeding occurs with severe pain, fever, chills, difficulty passing urine, or other concerning symptoms. A stone blocking urine flow can sometimes be associated with infection and requires urgent assessment.

For anyone experiencing persistent urinary symptoms or suspected Kidney Stone Disease, consultation with an experienced urology team, such as Kapoor’s Kidney & Urostone Centre, can help determine the cause and appropriate treatment.
