慢性前列腺炎患者前列腺液中尿酸检测及临床意义

目的:检测慢性前列腺炎患者EPS中的尿酸(UA)水平并探讨其临床意义。方法:按NIH诊断标准确诊的91例慢性前列腺炎患者分为2组,ⅢA组(n=48)和ⅢB组(n=43)。对照组(n=22)为无慢性前列腺炎的健康志愿者。分别进行CPSI评分,EPS中WBC计数、pH值及UA浓度测定。结果:ⅢB组的EPS中UA浓度[(257.02±144.84)μmol/L]显著高于ⅢA组[(159.73±121.49)μmol/L,P<0.01]和对照组[(78.55±44.53)μmol/L,P<0.01]。EPS中UA水平与pH值之间呈负显著相关(r=-0.398,P<0.01),而与CPSI疼痛症状评分(CPSI-P)、排尿症状评分(CPSI-U)以及CPSI总分(CPSI-T)之间均呈显著正相关(r分别为0.436、0.316、0.403,P均<0.01)。结论:前列腺内的UA浓度升高可能会导致化学性炎症反应。EPS中的UA水平与慢性前列腺炎的症状相关。检测EPS中的UA水平对慢性前列腺炎的诊断和治疗具有重要意义。

Determination of Uric Acid in the Expressed Prostatic Secretion of Chronic Prostafitis Patients and Its Clinical Significance

OBJECTIVE: To determine the level of uric acid (UA) in the expressed prostatic secretion (EPS) of chronic prostatitis patients and explore its clinical significance. METHODS: 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. RESULTS: 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). CONCLUSION: 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.
