Abstract

Introduction
The purpose of the current study was to investigate the separation of the bacterial factors of men’s urinary tract infections using the prostate massage technique and comparing them with the initial-stream urine, midstream urine, and end-stream urine in Tehran’s Health Centers. 
 
Methods
In this study, samples were collected from 50 men with genital-urinary tract defects who were referred to medical centers. During sampling, demographic information, medical history, and drugs are taken were asked from patients. Prostate secretions and first-void urine (VB1) were collected from the first 25 patients; prostate secretions and VB1, midstream urine (VB2), and end-stream urine (VB3) were collected from the second 25 patients.
 
Results
Using prostate secretions culture, out of the first 25 samples, 7 samples (28%) were infected by Mycoplasma hominis and 9 samples (36%) were infected by Ureaplasma urealyticum. using VB1 culture it was analyzed that 6 samples (24%) were infected by Mycoplasma hominis and 8 samples (32%) were infected by Ureaplasma urealyticum. In the second 25 samples, Bacterial contamination was seen in 23 samples (92%) by prostate secretions culture. VB1 culture showed bacterial contamination in 14 samples (56%). VB2 and VB3 cultures showed bacterial contamination in 3 (12%) and only 2 samples (8%), respectively.
 
Conclusions
In conclusion, the results obtained from the prostate secretions culture were more accurate and precise than the VB1 culture, but they were close to each other. Therefore, instead of using prostate massage which can be irritating for the patients or if the patient does not have prostate secretions, VB1 culture can be used.
