Centrifuged and noncentrifuged first-cath urine screening for male urethritis

In this investigation a comparison was made between the method for dounting leucocytes in first and final voided centrifuged urine samples and that for noncentrifuged urine samples. Among 417 patients, with a presumed diagnosis of urethritis, 216 had their diagnosis confirmed by the centrifuged urine method and 221 by that which did not use centrifugation. This difference was considered signficant and showed the superiority of the method which did not use centrifugation
