Home screening for hematuria: results of a multiclinic study.

The majority of urinary tract tumors cause bleeding in the urine. A program designed to detect hematuria before it is grossly apparent may contribute to earlier detection and more successful treatment of these malignancies. To test this hypothesis a hematuria home screening study was conducted. A total of 1,340 healthy men 50 years old or older used chemical reagent strips for 14 consecutive days to test the urine. Of the men 283 (21.1%) had at least 1 episode of hematuria. Of the 192 hematuria positive men who received a complete urological evaluation 16 (8.3%) had urological cancers and 47 (24.5%) had other hematuria-causing diseases that required immediate treatment. The quantity and frequency of hematuria were not related to disease severity. A hematuria home screening regimen is feasible and economical, and may promote the early detection of urinary tract cancers and other diseases in men more than 50 years old.
