545 male patients with a tentative diagnosis "urethritis" were examined bet
ween November 1984 and December 1994 in the Department of Dermatology and V
enerology of the Military Hospital in Ulm. The patients, aged from 18 to 58
years (mean age 24.1 years), were examined according to a standardized dia
gnostic procedure:
Smear preparations from the urethra with subsequent gram staining, bacteria
l cultures for aerobic bacteria, Neisseria gonorrhoeae (cultures and Phadeb
act gonococcus test), mycoplasma cultures (Mycoplasma hominis (M. hom.); Ur
eaplasma urealyticum (U. u),and Chlamydia trachomatis using several methods
, primarily DIFT (Syva Micro-Trak(R)).
Trichomonas vaginalis counts in urine sediment
441 patients (81%) had 4 or more leukocytes per high-power (x1000) field in
the gram stained specimens. In these 441 urethritis patients the following
germs could be detected: Trichomonas vagin 3 (1%), N.gonorrhoeae 80 (18%),
Mycoplasma 94 (21%) [U, u.59, M, hem. 24, both 11], C. trachomatis 114 (26
%), other pathogenic bacteria 135 (31%). In 114 patients (26%) no bacteria
could be identified.A single infection was diagnosed in a total of 242 pati
ents (55%), a double infection was determined in 71 patients (16%) while a
triple infection was found in 14 patients (3%). The spectrum determined in
the single infection included the following: N. gonorrhoeae 41 (9%), Mycopl
asma 45 (10%), C. trachomatis 67 (15%), other pathogenic bacteria 89 (20%)
(most frequently found germs were Enterococcus, beta-hemolytic Streptococcu
s, Escherichia coli, Staph. aureus). In the double infections combinations
with aerobic bacteria dominated. In triple infections, mycoplasma were most
common. During the investigation period the number of patients with urethr
itis symptoms declined at a constant rate.
