Comparison of different methods of urine sampling to estimate bacteriuria in male patients

ABSTRACT

This work was done to elicit the validity of different urine specimens taken by both clean and unclean methods on the culture of organisms in male patients with pyuria; thus trying to facilitate the methods of sampling. Urine samples from 25 patients complaining of acute dysuria or other irritative genito-urinary symptoms were collected by different methods [unclean urine sample, mid-stream clean catch urine sample, urethral catheterization and suprapubic aspiration]. Culture interpretation was done for these specimens. In our study we found that all patients [100%] who showed a positive culture by unclean first void urine sample gave identical results as those taken by clean catch midstrean urine, urethral catheterizalion and suprapubic aspiration. Thus, the first void urine is an easy and accurate method for taking samples from men. As most previous studies, we demonstrated that the common organism causing urinary tract infection in men is E. Choli followed by Staphylococci and to a lesser extent Klebsiella, Proteus and Pseudomonas organisms
