To determine the level of uric acid (UA) in the expressed prostatic secretion (EPS) of chronic prostatitis patients and explore its clinical significance.
A total of 91 patients with chronic prostatitis diagnosed by NIH standard were divided into a III A (n = 48) and a III B (n = 43) group, and healthy volunteers were selected as the control. The scores on the NIH-Chronic Prostatitis Symptom Index (CPSI) and the WBC count, pH value and UA level in EPS were evaluated for all the three groups.
The EPS UA concentration was (257.02 +/- 144.84) micromol/L in Group III B, significantly higher than in Group III A, (159. 73 +/- 121.49) micromol/L, (P < 0.01), and the control, (78.55 +/- 44.53) micromol/L, (P < 0.01). The level of EPS UA was correlated negatively with pH value (r = -0.398, P = 0.000), but positively with CPSI-P, CPSI-U and CPSI-T (r = 0.436, 0.316 and 0.403, P < 0.01).
Backflow of urine into prostatic ducts might cause chemical inflammation reaction by increasing UA concentration. There is a close relationship between the UA level in EPS and chronic prostatitis symptoms. Determination of the UA level in EPS is of great significance for the diagnosis and treatment of chronic prostatitis.
