男性泌尿生殖道支原体感染标本采集研究

目的:探讨男性泌尿生殖道不同标本(尿道分泌物、前列腺液、精液)支原体检测结果的差异。方法:对初诊疑泌尿生殖道感染者412例,复查患者308例。分别取尿道分泌物、前列腺液、精液为标本进行支原体检测。结果:初诊412例中,尿道分泌物标本支原体阳性194例,占47.0%;前列腺液标本支原体阳性202例,占49.0%;精液标本支原体阳性214例,占51.9%;214例精液支原体阳性标本覆盖前列腺液标本阳性202例,覆盖尿道分泌物标本阳性194例。精液支原体阳性漏诊率为0,前列腺液漏诊率为5.6%,尿道分泌物漏诊率为9.3%。三个标本组两两间比较支原体阳性率及漏诊率无显著性差异。复查患者308例,尿道分泌物标本支原体阳性30例,占9.7%;前列腺液标本支原体阳性61例,占19.8%;精液标本支原体阳性77例,占25.0%。77例精液标本支原体阳性覆盖前列腺标本支原体阳性59例。漏诊2例;覆盖尿道分泌物标本支原体阳性30例;总阳性79例,精液标本支原体漏诊率2.5%(2/79),前列腺液标本支原体漏诊率22.8%(18/79),尿道分泌物标本支原体漏诊率62.0%(49/79)。前列腺液标本支原体阳性率与尿道分泌物标本支原体阳性率比较有显著性差异;精液标本支原体阳性率与前列腺液标本支原体阳性率比较无显著性差异;精液标本支原体阳性率与尿道分泌物标本支原体阳性率比较有显著性差异。标本组间两两比较漏诊率均有显著性差异。结论:精液标本覆盖面广,支原体培养标本应首选精液。

Research on malegenitourinary tract mycoplasma sample Collection

Objective:To investigate the distinction of mycoplasma detection in different sample collected from male genitourinary tract (urethral secretions, liquor prostaticus, ejaculum). Methods: Urethral secretions, liquor prostaticus and ejaculum were collected respectively from 412 people who were preliminary diagnosed genitourinary tract infector and 308 patients who recheck. And then the samples were undertaken mycoplasma detection. Results: Among the 412 examples of preliminary diagnosed infector, 194 samples of urethral secretions were mycoplasma positive, occupying 47.0%, 202 samples of liquor prostaticus were mycoplasma positive, occupying 49.0%, and 214 samples of ejaculum were mycoplasma positive, occupying 51.9%. The rates of mycoplasma missed diagnosis in ejaculum, liquor prostaticus and urethral secretions were 0, 5.6% and 9.3%, respectively. Among the 308 examples of rechecking patients, 30 samples of urethral secretions were mycoplasma positive, occupying 9.7%, 61 samples of liquor prostaticus were mycoplasma positive, occupying 19.8%, and 77 samples of ejaculum were mycoplasma positive, occupying 25.0%. The 77 mycoplasma positive ejaculum samples cover the 59 mycoplasma positive liquor prostaticus samples, 2 examples were missed diagnosis. The 77 samples also cover 30 mycoplasma positive urethral secretions samples. The total positives are 79 samples. And the rate of mycoplasma missed diagnosis in ejaculum, liquor prostaticus and urethral secretions were 2.5% (2/79), 22.8%(18/79) and 62.0% (49/79), respectively. Conclusion: The coverage of ejaculum sample is wide. So ejaculum is the first choose to untake mycoplasma culture.
