Exercised-induced hematuria.

Bloody or discolored urine after exercise can have various etiologies. Exercise-induced hematuria is a common, benign cause of discolored urine following strenuous exercise. Evaluation of patients with this complaint begins with a thorough history, a focused physical examination and a microscopic examination of the urine. Using a systematic approach, the physician can detect serious, treatable problems, and testing can be limited. Patients with exercise-induced hematuria can be reassured that the condition is benign and that they can return to full activity.
