Abstract：
Obstructive azoospermia is a kind of common clinical disease, which often happens in epididymis, vas deferens and ejaculatory duct obstruction and accounts for male infertility. Azoospermia, which is caused by obstruction of the ejaculatory duct, is relatively rare. but the development of endoscopic technology now allows the disease to be resolved by surgery. In the past, transurethral resection of ejaculatory duct (TURED) has been used to treat patients with ejaculatory duct obstruction and azoosperm-free disease. But with the further study of TURED operation in recent years, as well as in patients with postoperative follow-up results showed that the urine - tube reflux and retrograde ejaculation ejaculation the incidence of iatrogenic injury is higherduring the TURED.therefore, in recent years, some experts committed to seeking a less damage and better effect of the surgical method. With the continuous development of endoscopic technology, seminal vesiculoscopy has come into being, which also creates conditions for further understanding the structure and function of the seminal vesicle and distal seminal duct, accurate diagnosis and minimally invasive treatment of the currently discovered diseases. In this article, we summarized the semen abnormalities associated with seminal vesiculoscopy in the treatment of ejaculatory duct obstruction, and also reviewed the surgical methods, clinical application and research progress of seminal vesiculoscopy.
摘要：
梗阻性无精子症是临床常见病,这经常发生在附睾，输精管和射精管阻塞和男性不育的原因。无精子症,这是由射精管阻塞引起的，相对罕见。但是内窥镜技术的发展现在可以通过手术解决这种疾病。在过去,经尿道射精管切除术（TURED）已用于治疗射精管阻塞和无精子疾病的患者。但随着近年来对TURED手术研究的深入,以及术后随访结果显示，尿管反流和逆行射精的患者在TURED期间医源性损伤的发生率较高。因此,近年来,一些专家致力于寻求一种损伤更小、效果更好的手术方法。随着内镜技术的不断发展,精囊镜检查已经出现，这也为进一步了解精囊和远端精管的结构和功能创造了条件，对目前发现的疾病进行准确的诊断和微创治疗。在这篇文章中,我们总结了精液异常与精囊镜检查治疗射精管阻塞相关的，并回顾了手术方法，精囊镜检查的临床应用及研究进展.
