To compare informative value of three tests (2-, 3- and 4-glass) in diagnosis ofprostatitis we examined 177 patients with chronic prostatitis (CP) who were randomized into 4 groups. Group 1 patients (n = 33) were examined with standard 4-glass test (Mearls and Stamey), patients of subgroup 2a (n = 42) were examined with 2-glass test before finger rectal test (FRT), FRT was made in subgroup 2b (n = 45) before urine collection (2 portions), group 3 (n = 57) was examined by an original technique proposed by the authors. While performing the latter test special focus was given to urination continuity, then the secretion obtained at FRT was studied. Efficacy of each of the tests was assessed by comfort of the procedure for the patient and the doctor, a proportion of false-positive results. The 3-glass test proved most informative and significant. Also, it is sensitive in detection of urogenital tuberculosis. The 4-glass test is not comfortable for both the patient and the doctor. The 2-glass test often produced false-positive results.
