精浆中性α-葡糖苷酶与附睾梗阻性无精子症梗阻部位的相关性研究

Neutral alpha-glucosidase activity is correlated with the location of epididymal obstruction in azoospermia men

目的:探讨精浆中性α-葡糖苷酶与附睾梗阻性无精子症梗阻部位的相关性。方法:59例附睾梗阻性无精子症患者,术前检测精浆中性α-葡糖苷酶水平,然后采用显微镜下阴囊探查术确定附睾梗阻部位。分析精浆中性α-葡糖苷酶与附睾梗阻部位的相关性。结果:双侧附睾尾部梗阻25例,双侧附睾体部梗阻15例,双侧附睾头部梗阻12例,一侧附睾头部对侧尾部梗阻4例,一侧附睾体部对侧尾部梗阻3例。双侧附睾尾部、体部、头部梗阻术前精浆中性α-葡糖苷酶水平分别为(4.1±1.9)、(13.8±4.4)、(46.8±19.3)mU/1次射精,3组间差异显著(P<0.05)。结论:精浆中性α-葡糖苷酶与附睾梗阻部位具有显著的相关性,可用于判断附睾梗阻的部位、手术愈后,缩短探查手术的时间。

Objective ： To evaluate the correlation of neutral alpha-glucosidase in seminal plasma with the location of epididymal obstruction in azoospermia men. Methods： We detected neutral alpha-glucosidase activity in the seminal plasma of 59 men with obstructive azoospermia followed by determining the location of epididymal obstruction by scrotal exploratory surgery. Then we analyzed the correlation between neutral alpha-glucosidase and the location of epididymal obstructive azoospermia. Results： Among the total number of patients, there were 25 cases of bilateral cauda epididymal obstruction, 15 bilateral corpus, 12 bilateral caput, 4 unilateral caput-opposite cauda, and 3 unilateral corpus-opposite cauda. The neutral alpha-glucosidase levels in the seminal plasma of bilateral cauda, corpus and capus epididymal obstructions were （4. 1 ± 1.9）, （13.8 ±4. 4） and （46.8 ± 19.3） mU per ejaculate, respectively, with statistically significant differences among the three groups （ P 〈 0.05 ）. Conclusion ： Neutral alpha-glucosidase activity is significantly correlated with the location of epididymal obstruction in azoospermia men, which helps to locate epididymal obstruction, evaluate surgical prognosis and reduce the time of scrotal exploratory surgery.
