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.
외래에서 혈뇨 환자를 접하게 되면, 환자의 활동성 및 운동 여부를 반드시 확인하고, 혈뇨가 운동으로 유발되고, 운동 중단 후 호전되는지 확인하여야 한다. 그리고 종양, 감염, 약물, 요석, 신염과 운동 유발 혈뇨를 감별하여, 검사의 진행여부를 결정해야 한다. 하지만 운동 유발 혈뇨가 다른 신장-비뇨기계의 증상 중 하나일 수 있기 때문에 반복적인 혈뇨, 연령 등에 따라 검사가 필요함을 염두해 두어야 한다.
