Chinese Journal of Urology 2009;30(2):127-129
Objective To analysis the differences of age, prostate volume, serum PSA and PSAD, IPSS between the BPH and BPH with prostatitis. Methods Clinical data of 100 patients whom received surgical treatments with a pathologic diagnosis of BPH were retrospectively analyzed. The occurrence of prostatitis was determined by pathology. The differences of age, prostate volume, serum PSA and PSAD, IPSS between the BPH cases and BPH with prostatitis cases were analyzed. The capability of B-ultrasound in diagnosis of the prostatitis combined with BPH was evaluated. Re-suits 66% BPH patients were found combined with prostatitis. There was a significant correlation between inflammatory infiltration grade and aggressiveness grade (r= 0. 772, P<0. 001). There was a moderate correlation between prostate volume and patient age(r= 0. 420, P<0. 001). There was a low correlation between serum PSA and patient age (r= 0. 258, P<0. 01) while no significant correla-tion between PSAD and age. The patient age of BPH combined with prostatitis group was significantly higher than BPH group (P<0. 05). Average prostate volume of combined with prostatitis group was significantly higher than BPH group (P<0. 05). There was a significant correlation between prostate volume and inflammatory infiltration grade(r=0. 292, P=0. 003), PSA and aggressiveness grade(r=0. 254, P=0.007). Both average PSA and PSAD of BPH combined with prostatitis group were signif-icantly higher than the BPH group (P<0. 05). When the factor of difference in age distribution was considered, the conclusion were still valid (P<0.05). On α= 0.05 level, relatively low correlations were found between PSA and inflammatory infiltration grade(r=0. 319, P=0. 001), PSA and aggres-siveness grade(r=0. 214, P=0. 032), PSAD and inflammatory infiltration grade ( r=0. 212, P=0. 034). There was no significant correlation between PSAD and aggressiveness grade(r=0.081 ,P=0.425). Average IPSS of combined with prostatitis group were significantly higher than BPH group. On diagnosis of the combined prostatitis in BPH, the sensitivity of ultrasonic was 21.2% with a speci-ficity of 82.4%. Conclusions Prostatitis is often found in more than half BPH samples. The BPH with prostatitis usually has bigger prostate volume, higher PSA, PSAD and may present relatively se-verer clinic syndromes.
