Abstract
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 analysis. We compared classification based on evaluation of these 3 specimens to the traditional classification based on expressed prostatic secretion examination alone. MATERIALS AND METHODS: A prospective clinical and laboratory protocol was used to evaluate symptomatic patients who had no evidence of urethritis, acute bacterial prostatitis or chronic bacterial prostatitis. RESULTS: Thorough clinical and microbiological evaluation of 310 patients attending our prostatitis clinic was used to select a population of 140 subjects who provided optimal expressed prostatic secretion, post-massage urine and semen specimens. Inflammation was documented in 111 (26%) of 420 samples, including 39 expressed prostatic secretion samples with 500 or greater leukocytes/mm.3, 32 post-massage urine samples with 1 or greater leukocytes/mm.3 and 40 seminal fluid specimens with 1 or greater million leukocytes/mm.3. Of the 140 subjects 73 (52%) had inflammatory chronic prostatitis/pelvic pain according to the consensus criteria but only 39 (28%) had nonbacterial 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 category of nonbacterial prostatitis.
