对９０例性病门诊慢性前列腺炎患者前列腺液及３６名正常对照组的前列腺液进行解脲支原体（ＵＵ）及人型支原体（ＭＨ）培养。结果表明，慢性前列腺炎组ＵＵ阳性１８例（２０００％），ＭＨ阳性４例（４４４％）；对照组ＵＵ、ＭＨ均为阴性。两组ＵＵ阳性率，经统计学处理有显著性差异（Ｐ＜００１）。作者认为，ＵＵ是性病后慢性前列腺炎的主要病原体之一 Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) were cultured in prostatic fluid from 90 STD clinic patients and prostatic fluid from 36 healthy controls. The results showed that 18 cases (2000%) had positive UU and 4 cases (444%) positive for MH in chronic prostatitis group. The UU and MH in the control group were all negative. The positive rates of UU in both groups were statistically significant (P <001). The authors believe that UU is one of the major pathogens of chronic prostatitis after sexually transmitted diseases
