Objectives: Asymptomatic microscopic hematuria is often discovered as part of a routine examination; some of these patients are likely to have clinically significant diseases and a full urologic evaluation is justified. To address the signifcance of asymptomatic microscopic hematuria, OPD patients with asymptomatic microscopic hematuria were evaluated for the underlying urologic diseases. Methods: We retrospectively evaluated the data of 84 patients with asymptomatic microscopic hematuria, but without other urinary symptoms, from 1999 to 2001. All patients received a series of studies including urine analysis, urine cytology, intravenous urography (IVU) or renal ultrasonography (US) and cystoscopy. Results: A total of 84 patients were enrolled. There were 26 men and 58 women agerange, 13 to 83 years (mean: 48.8). Sixty-three patients (75%)showed normal findings. Twenty-one patients (25%) had abnormal findings which included 12 (14.2%) stones (2 staghorn stones, 2 ureteral stones and 8 small renal stones), l (1.2%) urinary bladder TCC, 1 (1.2%) renal cyst, 6 (7.1%) bladder neck polyps, 2 (2.4%) urinary bladder diverticulums, l (1.2%) telangiectasis and l (1.2%) urethra stricture. In all 84 patients, 3 patients had two problems. They received further operations for their underlying disease: TUR-Bt (1), PCNL (2) and URSL (2). Conclusions: Causes of asymptomatic microscopic hematuria range from minor, incidental findings that do not require treatment to highly significant lesions that immediately threaten the patient's life. Patients with asymptomatic microscopic hematuria should undergo an appropriate evaluation because it will often determine the cause of the hematuria.
