Abstract

To assess the validity of the American Urological Association guidelines, we investigated 14-year outcomes of men aged > or = 50 years who had hematuria detected in a bladder cancer (BC) screening trial, were thoroughly evaluated, and were not found to have urological cancers. The American Urological Association guidelines for follow-up of adults with asymptomatic microhematuria (MH) who have negative evaluations include repeat urinary cytologies, urinalyses, and office visits for several years, primarily to detect BC (Cohen and Brown, N Engl J Med 348: 2330-2338, 2003; and Grossfeld et al, Urology 57:604-610, 2001). Of 1575 screening participants, 258 had MH detected by daily home testing with the Ames hemastix during two 14-day periods. This test has been shown to accurately reflect MH on microscopic urinalysis when each is correctly performed. Any man with at least 1 positive test (> or = "trace") underwent a complete evaluation including microscopic urinalysis, culture, cytology, complete blood count, serum creatinine, coagulation profile, intravenous urography or computed tomography scan, and cystoscopy. BC or other urological tumors was not detected in 234 participants. Using Wisconsin state tumor registry and death certi...Continue Reading
