摘要
目的探讨经直肠超声对诊断和评估慢性前列腺炎所致男性不育症的价值。方法对2013-06~2015-11我院门诊以不育就诊的男性患者进行筛查,发现43例不育患者伴有慢性前列腺炎。采用经直肠超声、尿四杯检查以及精液分析等,对43例不育患者与30例健康对照者的前列腺液、精液和前列腺超声改变进行研究。结果 143例不孕患者中,25例（58.1%）表现为无力型精子症,11例（25.6%）表现为畸形精子症,7例（16.3%）表现为少精子症。2慢性前列腺炎组的超声检查主要表现为前列腺体积稍增大,内腺回声减低,边缘伴钙化,有不均回声光点,前列腺尿道动脉血流丰富,流速增快。3与健康对照比较,慢性前列腺炎所致男性不育患者的前列腺尿道动脉收缩期峰值血流速度（PSV）及阻力指数（RI）显著增高,差异有统计学意义（P〈0.01）,而两组的前列腺包膜动脉PSV及RI差异无统计学意义（P〉0.05）。结论慢性前列腺炎致不育患者的前列腺有比较特异的超声表现,经直肠彩色多普勒超声检查可以为慢性前列腺炎所致男性不育患者提供准确的二维超声及血流动力学指标,有助于男性不育症病因的诊断。
Objective To explore the value of transrectal ultrasound in the diagnosis and assessment of male infertility caused by chronic prostatitis. Methods A total of 43 infertile males with chronic prostatitis and 30 normal controls were included in the study from June 2013 to November 2015. The prostatic fluid,semen and prostate ultrasound changes were studied by transrectal ultrasound,urine four-cup test and semen analysis. Results 1 Among 43 infertile males with chronic prostatitis,25 cases（58. 1%）suffered from asthenozoospermia,11 cases（25. 6%）suffered from teratozoospermia,and 7 cases（16. 3%）suffered from oligospermatism. 2The ultrasound showed enlarged prostate volume,lower resonance of the inner gland,marginal calcification,low-level uneven echo,abundant blood flow in the urine vein of prostate and increased velocity in chronic prostatitis patients. 3The peak systolic velocity（PSV）and resistant indexes（RI）of prostatic urethra arteries and seminal vesicles arteries in male infertility patients with chronic prostatitis were significantly higher than in normal controls（P 0. 01）,but PSV and RI of prostatic capsule arteries showed no significant difference between two groups（P 0. 05）. Conclusion Transrectal ultrasound can provide specific sonographic findings and objective hemodynamic indexes of the infertile males with chronic prostatitis,which is helpful in the screening of etiological factors of the male infertility.
