    Abstract:
    OBJECTIVE: Asymptomatic microhematuria continues to be a problem. It has a prevalence of 16% and numerous conditions can present this clinical manifestation. METHODS: A prospective study was carried out on all patients that consulted at the urological services during 2000 for asymptomatic hematuria. Patients presenting with irritative symptoms, urethral secretion, perineal or suprapubic pain, urinary tract infections, renal lithiasis or history of trauma were not included in the study. RESULTS: None of the patients presented tumors. Two patients presented renal lithiasis, 5 simple renal cysts, 8 hypercalciuria and 3 hyperuricosuria. None of the 11 patients with hypercalciuria or hyperuricosuria had a history of lithiasis. CONCLUSIONS: Although the size of the study is small, the incidence of tumors in patients with asymptomatic microhematuria appears to be far from the 12.5% incidence reported by some authors and might probably be closer to the 0.5% incidence reported by others. Furthermore, the significant pathology (renal lithiasis), which requires treatment, is also infrequent.
