Jn. Krieger et al., Does the chronic prostatitis/pelvic pain syndrome differ from nonbacterialprostatitis and prostatodynia?, J UROL, 164(5), 2000, pp. 1554-1558
Purpose: The new consensus classification considers the chronic prostatitis
/pelvic pain syndrome (CPPS) based on presence or absence of leukocytes in
the expressed prostatic secretions, post-massage urine or seminal fluid ana
lysis. We compared classification based on evaluation of these 3 specimens
to the traditional classification based on expressed prostatic secretion ex
amination alone.
Materials and Methods: A prospective clinical and laboratory protocol was u
sed to evaluate symptomatic patients who had no evidence of urethritis, acu
te bacterial prostatitis or chronic bacterial prostatitis.
Results: Thorough clinical and microbiological evaluation of 310 patients a
ttending our prostatitis clinic was used to select a population of 140 subj
ects who provided optimal expressed prostatic secretion, post-massage urine
and semen specimens. Inflammation was documented in 111 (26%) of 420 sampl
es, including 39 expressed prostatic secretion samples with 500 or greater
leukocytes/mm.(3), 32 post-massage urine samples with 1 or greater leukocyt
es/mm.(3) and 40 seminal fluid specimens with 1 or greater million leukocyt
es/mm.3. Of the 140 subjects 73 (52%) had inflammatory chronic prostatitis/
pelvic pain according to the consensus criteria but only 39 (28%) had nonba
cterial prostatitis according to traditional expressed prostatic secretion
criteria (p <0.001).
Conclusions: The new consensus concept of inflammatory chronic prostatitis/
pelvic pain includes almost twice as many patients as the traditional categ
ory of nonbacterial prostatitis.
