A Case of Exercise-Induced Hematuria Presenting as Gross Hematuria Lasting One Week / 대한내과학회지

ABSTRACT

Exercise-induced hematuria is a phenomenon occurring in subjects who participate in strenuous exercise. Rapid resolution is an important feature of exercise-induced hematuria. We report here a case of exercise-induced hematuria presenting as gross hematuria lasting 1 week in a 19-year-old male patient. Gross hematuria developed after strenuous exercise about 3 years ago. Three months ago, recurrent gross hematuria was lasting 1 week, regardless of exercise intensity. Compression of the left renal vein between the aorta and superior mesenteric artery, without prominent venous collaterals, was detected by computed tomography. However, no abnormalities were detected by renal venography, arteriography or kidney biopsy. Exercise-induced hematuria occurs with a high incidence, but is self-limiting. In contrast, recurrent and gross hematuria can be associated with bladder carcinoma or vascular abnormality. This should be kept in mind, and urological evaluations such as cystoscopy and angiography are necessary in gross and recurrent hematuria.
