Application of the urine-prostate-semen test in accurate diagnosing etiologically in the patients with chronic prostatitis-like symptoms 

Background: In diagnosis and differential diagnosis of chronic prostatitis-like symptoms, the prostatic secretion was considered to be the most important and even only specimen, little attention has been paid to other genital organ infections. This may be one of important factors affecting treatment effect of chronic prostatitis. Methods: : We used a urine-prostate-semen test (U-EPS-S test) to collect the specimens of urine, prostatic secretion and semen from 200 patients with chronic prostatitis-like symptoms. The specimens were inoculated respectively into a suitable media culture for the bacteriological localization detection and observe the number and their distribution of colonies in each isolation culture. Results: : All of the patients had an infection of the internal genital organs (infection rate = 100%). Of these, prostatic secretion positive isolation cultures were obtained in 66 cases (33%), semen positive isolation cultures were obtained in 34 cases (17%), and prostatic secretion and semen positive isolation cultures were obtained in 100 cases (50%). Conclusion: The U-EPS-S test is useful to identify the pathogens and contaminatives in isolation cultures, and accurate diagnose and differential diagnose the multiple microbial infection (MMI) and the multi-organ infection (MOI) in patients with chronic prostatitis-like symptoms.
