From January 1981 through December 1986, 27, 513 individuals consisting of 17, 918 males and 9, 595 females underwent health examinations at Health Care Center in Obihiro Kosei Hospital. 14.2% of healthy and asymptomatic men and 29.1% of healthy and asymptomatic women had microscopic hematuria (one or more RBCs per HPF).
To evaluate the clinical significance of microhematuria, about one third of patients with asymptomatic microhematuria who had undergone complete urological examination were reviewed.
Genitourinary neoplasms were found in 0.21%(8 bladder cancers, 2 prostatic cancers and 1 renal cell cancer). The incidence of cancers increases proportionate to increase in age, furthermore, lesions were found more commonly in men than in women. We could find no relationship between the degree of hematuria and the cause. The results suggest that patients with asymptomatic microhematuria should undergo urological examinations.
