To determine whether the results of voided urine cultures in men are affected by meatal cleansing, midstream sampling, or circumcision status, 308 paired (initial and midstream) specimens were collected from 254 urology clinic patients. Half of the patients cleansed their urethral meatus with povidone-iodine prior to voiding. The circumcision status of all patients was noted. The rates of true bacteriuria (growth of 104 or greater colony-forming units/ml urine with a single predominant species) and contamination (growth of 103 or greater colony-forming units/ml urine with two or more colonial types) were compared in the various collection technique subgroups. Neither the bacteriuria nor contamination rates were significantly different (p > 0.05) in circumcised and uncircumcised patients, or in those who cleansed their meatus and those who did not. Contamination, but not bacteriuria, rates were higher in initial as compared with midstream specimens. These data suggest that the clean-catch midstream void procedure is unnecessary for obtaining routine voided urine culture specimens from men.
