Summary
Strenuous exercise can cause hematuria, or blood in the urine, due to traumatic or non-traumatic injury. This common sports-related condition is usually self-limiting but requires careful evaluation.
Area of Science:
- Urology
- Sports Medicine
- Nephrology
Background:
- Intensive physical activity places significant stress on the body, potentially leading to urinary tract abnormalities.
- Hematuria, the presence of blood in the urine, is a common finding after strenuous exercise in both contact and noncontact sports.
Purpose of the Study:
- To explore the pathophysiology of exercise-induced hematuria.
- To differentiate sports hematuria from other causes of reddish urine.
Main Methods:
- Review of mechanisms causing exercise-induced hematuria, including traumatic and non-traumatic pathways.
- Distinguishing sports hematuria from march hemoglobinuria and exercise myoglobinuria.
Main Results:
- Traumatic causes include direct renal or bladder injury.
- Non-traumatic causes involve renal vasoconstriction leading to nephron hypoxia and increased glomerular permeability, or efferent arteriolar constriction increasing filtration pressure.
- Sports hematuria involves whole blood, unlike hemoglobinuria or myoglobinuria.
Conclusions:
- Exercise-induced hematuria is typically benign and self-resolving.
- It is crucial to rule out underlying urinary tract pathologies despite the benign nature of sports hematuria.
