Reliability of a single urine culture in establishing diagnosis of asymptomatic bacteriuria in adult males.
Fifty-nine asymptomatic men without catheters of ileal-loop bladders, who were attending a urology clinic and were incidentally discovered to have 100,000 or more Enterobacteriaceae per ml ("significant bacteriuria") in a clean voided urine sample, were prospectively evaluated. To identify these 59 patients, 5,876 urine samples, collected exclusively from men, had been subjected to quantitation and identification. A repeat urine culture performed on these patients invariably confirmed the results of the initial culture. The reproducibility of a single urine culture containing significant bacteriuria occurred independently of the tissue source of infection, as determined by the antibody-coated-bacteria immunofluorescence test. We conclude that a single urine culture obtained from a cooperative man can establish the diagnosis of asymptomatic bacteriuria.
