To investigate the ultrasonographic features of obstructive azoospermia and to evaluate transrectal ultrasonography in the diagnosis of the disease.
We performed transrectal ultrasonography for 248 patients with obstructive azoospermia, observed the sonographic features of the prostate gland, seminal vesicle and ejaculatory duct.
The average volume of the prostate gland of the studied group was 13.2 ml. A total of 111 cases showed normal sonographic features, 39 cases bilateral seminal vesicle defect, 33 cases bilateral seminal vesicle aplasia, 23 cases unilateral seminal vesicle defect and contralateral seminal vesicle aplasia, 28 cases bilateral and 14 cases unilateral seminal vesicle dilatation. Of the 42 cases of seminal vesicle dilatation, 18 had ejaculatory duct dilatation and 17 had cysts in the midline of the prostate.
Obstructive azoospermia varies in kind. Transrectal ultrasonography can reveal the details of the prostate, seminal vesicle and ejaculatory duct and help to classify obstructive azoospermia and determine the location of the lesion.
探讨梗阻性无精子症的超声特征，并评估经直肠超声检查在该疾病诊断中的价值。
对248例梗阻性无精子症患者进行经直肠超声检查，观察前列腺、精囊及射精管的超声特征。
研究组前列腺平均体积为13.2 ml。共111例超声表现正常，39例双侧精囊缺如，33例双侧精囊发育不全，23例一侧精囊缺如对侧精囊发育不全，28例双侧及14例一侧精囊扩张。在42例精囊扩张患者中，18例伴有射精管扩张，17例前列腺中线有囊肿。
梗阻性无精子症类型多样。经直肠超声检查可显示前列腺、精囊及射精管的细节，有助于梗阻性无精子症的分类及病变部位的确定。
