摘　　要：目的探讨经直肠超声在梗阻性无精子症检查中的临床价值。方法回顾性分析42例临床诊断为梗阻性无精子症患者的临床资料,总结分析梗阻性无精子症患者的前列腺、精囊及射精管的经直肠声像图表现。结果本组病例前列腺的体积为8.2~19.9 mL,平均13.5 mL,经直肠超声检查前列腺、双侧精囊腺、输精管壶腹及双侧射精管无异常者23例,前列腺发育不良2例,前列腺中线部位囊肿4例;双侧精囊发育不良或缺如4例,精囊慢性炎症2例;射精管囊肿3例,射精管结石2例,射精管闭锁1例,射精管慢性炎症1例。结论梗阻性无精子症的梗阻原因多样;经直肠超声可以清晰显示前列腺、精囊及射精管的结构与病变,有助于判断梗阻性无精子症的病变类型及梗阻部位,可视为梗阻性无精子症的首选检查方法。Objective To investigate the evaluation of transreetal uhrasonography in the diagnosis of obstructive azoospermia. Methods We performed transrectal uhrasonography for 42 patients with obstructive azoospermia, observed the sonographic features of the prostate gland, seminal vesicle and ejaculatory duct. Results The volume of the prostate gland was in the range of 8.2ml to 19.9 mL, and the average volume was 13.5 mL. A total of 23 cases showed normal sonographic features ; 2 cases prostate aplasia, 4 cases had cysts in the midline of the prostate ; 4 cases bilateral seminal vesicle defect or aplasia, 2 cases chronic seminal vesiculitis; 3 cases had cysts and 2 cases had stone in ejaculatory duct, 1 case ejaculatory duct atresia, 1 case had chronic inflammation in ejaeulatory duct. Conclusion The reason of obstruction varies in kind. Transrectal ultrasonography can reveal the details of the prostate, seminal vesicle and ejaculatory duct and help to classify ob- structive azoospermia and determine the location of the lesion. It can be regard as the first examination for the patients with obstructive azoospermia.
