阻塞性不育症的诊断中必须考虑射精管阻塞。若精液量少于1ml,精液中精子数极少甚至没有,精液呈水样,pH6～7,不能凝固也没有特殊气味者,应考虑射精管阻塞。若这些特点均存在则不必再作精液果糖测定,如测定果糖,也必定低或缺乏。若这些特点不存在,则阻塞的可能性较少。为排除此病,可作输精管穿刺,若无远端阻塞,输精管内仅有微量液体。通过钝头23号针头,将10ml无菌盐水注入远端输精管,如药液注完仅少许压力,则表示远端无阻塞。再用5～10ml稀释美蓝液(1ml美蓝于10ml盐水中)证实,导尿尿液为蓝色者为通畅。对侧可用5～10ml稀释氢化荧光素液(1ml氢化荧光素于25ml盐水中)注射,尿液呈黄、绿或
Obstruction of the ejaculatory duct must be considered in the diagnosis of obstructive infertility. If the amount of semen less than 1ml, the number of sperm in the semen with little or no semen was watery, pH6 ~ 7, can not coagulate nor have a special smell, should consider the vas deferens obstruction. If these characteristics are present you do not have to make semen fructose determination, such as the determination of fructose, must also be low or lack of. If these features do not exist, then less likely to block. To rule out the disease, for vas deferens puncture, if there is no distal obstruction, vas deferens only trace liquid. Through the blunt tip 23 needle, 10ml sterile saline into the distal vas deferens, such as liquid injection note only a little pressure, then the distal non-blocking. Re-use 5 ~ 10ml diluted methylene blue solution (1ml methylene blue in 10ml saline) confirmed that the catheterization of urine for the blue were unobstructed. The opposite side can be used 5 ~ 10ml diluted fluorescein solution (1ml of fluorescein in 25ml saline) injection of urine yellow or green or
