We present a case study of 2 young men referred to our department with presumed macroscopic haematuria based on red dyscologation of the urine as well as the presence of hemoglobin in the urine which was determined by a urine test strip. Laboratory-confirmed significant rhabdomyolysis with myoglobinuria required hospitalization for renoprotective treatment.
When examining young and otherwise healthy individuals for hematuria, myoglobinuria has to be considered in the differential diagnosis and the patient should be asked specifically about prior physical exertion.
