[Four-glass or two glass test for chronic prostatitis]

Abstract

Chronic pelvic pain syndrome is still an important clinical problem. The NIH prostatitis classification introduced in 1998 for diagnosis and treatment measures is based on extended microbiological analysis of urine and expressed prostate secretion (4-glass test). In 1997 J.C. Nickel proved that the culture and microscopic examination of urine before and after prostatic massage leads to the same results as the 4-glass test. In our prospective study on 143 patients with a diagnosis of chronic prostatitis, we analyzed this statement and came to the same results. We therefore recommend replacing the expensive and time-consuming 4-glass test by a simple preprostatic and postprostatic massage urine culture. Further examinations should only be performed in special cases.
