Hypercalciuria: A Rare Contributing Cause of Exercise-Induced Visible Haematuria

Exertional haematuria is a relatively common reported symptom. We present a case of exercise induced haematuria in a long distance runner with proven hypercalciuria. Our case report highlights that urothelial calcifications in patients with hypercalciuria have the potential to cause traumatic haematuria during high intensity exercise. Whilst diagnostic work up of haematuria still applies, careful attention to the history in this specific group of patents has the potential to avoid further invasive investigations, such as renal biopsies.
