Chronic bacterial seminal vesiculitis as a potential disease entity in men with chronic prostatitis.

AbstractOBJECTIVES:
To investigate bacterial infection in the seminal vesicles by bacteriological examination and radionuclide imaging in men with chronic prostatitis.
METHODS:
The study included 50 patients with chronic prostatitis who showed hot uptake in seminal vesicles on Tc-99m ciprofloxacin imaging and eight patients who did not show hot uptake. The evaluation included the National Institutes of Health Chronic Prostatitis Symptom Index and four-glass test. In all participants, transperineal aspiration of seminal vesicle fluid under the guidance of transrectal ultrasonography and bacteriological examination was carried out.
RESULTS:
Of the 50 patients who showed hot uptake in the seminal vesicles on the isotope study, microorganisms were isolated from the seminal vesicle fluid in 17 patients (positive predictive value, 34%). The most common causative organisms were Escherichia coli in 13 patients (26%), followed by coagulase-negative Staphylococcus species in two patients (4%), Enterococcus faecalis in one patient (2%) and Chlamydia trachomatis in one patient (2%). No microorganisms were isolated in the eight patients who did not show hot uptake in the seminal vesicles (negative predictive value, 100%). However, there were no significant differences in National Institutes of Health Chronic Prostatitis Symptom Index total scores and subscores between the study groups.
CONCLUSIONS:
Chronic bacterial seminal vesiculitis might simultaneously affect a considerable portion of patients with chronic prostatitis, although the clinical implication of the disease remains to be further investigated.
