The authors report the findings from an on-going of 1764 vasectomized men followed up by means of the Scottish medical record linkage system for a total of 4500 man-years after operation. The authors view the results so far as reassuring regarding the safety of vasectomy, although the mean length of follow-up (2.6 years) is still short. The study will continue. Some features of this method of follow-up are described and discussed.
作者报告了一项正在进行的研究结果,该研究对1764名接受输精管切除术的男性进行了随访,通过苏格兰医疗记录链接系统在术后共随访了4500人年。作者认为,就输精管切除术的安全性而言,目前的结果令人安心,尽管平均随访时间(2.6年)仍然较短。该研究将继续进行。文中描述并讨论了这种随访方法的一些特点。
