输精管滤过装置节育术的临床研究

本文报告51例输精管腔植入由作者研制的输精管滤过装置与40例钳穿法输精管结扎术经过1至3年的临床比较研究。其结果:两组不同术式的节育有效率均为100％,滤过装置组术后1～3年仍有51.6％(16/31)测出中性α-糖苷酶活性,至今仅有12例附睾轻度肿胀和近附睾段输精管轻度增粗;而结扎组一年后均有不同程度的附睾肿胀和近附睾段输精管增粗,并有1例并发附睾淤积症。两组间有非常显著的统计学差异(P<0.005)。结果提示:输精管滤过装置不仅能限制精子通过而达到节育的目的,又不完全影响附睾液的排出,较好地避免或减少了附睾淤积的发生。因此,有可能作为一种新型的、非阻塞性的男性节育方法用于临床。     

Preliminary Clinical Study of Intra-vas Device

Fifty-one volunteers with implanted intravas device (IVD ) in comparison with 40 volunteers undergone no-scalpel vasectomy have been recruited for 1 to 3 years clinical follow-up study, The results demonstrate that efficacy rates of contraception in both the IVD group and the vasectomy group are 100%, Sixteen out of thirty - one volunteers (51.6% ) in the IVD group were found to have glucosidase activity in their seminal plasma 1 to 3 years after the operation. Only 12 subjects in the IVD
