<BR> 小刘夫妇结婚快三年了，还没有小孩。经医生检查，问题出在小刘身上。小刘睾丸大小、发育正常，性功能没问题，就是精液中没有精子。医生分析，可能是精子的输送管道（精道）堵塞了，使精子无法排出来。建议小刘做进一步检查以最后确诊?BR> <BR> 精道不通的病例中，最常见的是输精管道堵塞。检查输精管堵塞的方法可根据具体医疗条件来确定。最简单易行的方法的睾丸组织活检，即检查睾丸活组织。如果血中促卵泡素和睾酮含量正常，睾丸活组织检查也正常，可以肯定是输精管道被堵塞了，或者是先天性输精管发育不全。否则，可能是生精功能问题。也可以做一次Ｘ光照相，即做一次输精管精囊腺造影术。这种造影术早在１９１３年就用于临床了，因有一些副作用，一直没有得到很好的发展。过去做造影术时，要先切开阴囊皮肤，然后用注射针穿刺入输精管，将造影剂注入精囊腺方向后才能照Ｘ光片，根据该片可以判断精囊腺、前列腺、射精管、输精管、输精管壶腹部等有无问题。这种手术损伤大，加上当时所用的高浓度粘稠的造影剂会促进输精管阻塞，并可能造成感染，引起继发性阻塞。后来，人们改进了这种方法，采用亲水性造影剂，特别是不用开刀，直接经阴囊皮肤穿刺输精管，减轻了组织的损伤和病人的痛苦。实践证明这种改进了的方法，提高了安全性和成功率。但尚需在有条件的医院里才能进行这项检查?BR> 据国外资料报道，因精道阻塞造成的不育占男性不育的３－１０％，上海江鱼教授等报告可占０·６３％，其他也有人报告在２％左右的。引起精道阻塞的原因?BR> <BR> ①先天性异常；<BR> ②炎症、结核；<BR> ③外伤；<BR> <br><br>; ④囊肿或肿瘤?BR> ⑤外来压迫等?BR> ⑥杨氏综合征，此征常同支气管扩张合并?BR> <BR> 如果找到了阻塞部位，而且阻塞部位或闭锁部位不长，又可能手术的话，可以通过显微外科术予以吻合。如联邦德国汉堡大学多年来收治的３万多不育症患者中，有１千人属于这种梗塞性无精，即精道阻塞，其中一半有条件的患者进行了吻合手术。其他情况，可针对病情如炎症、结核等采取对症治疗方法?BR> <BR> <BR>
