在苏格兰过去10年睾丸肿瘤发生率有所升高,此间输精管切除术已成为一种较常用的避孕方法。本文对1977～1987年某医院的37例(60岁以下)诊为睾丸肿瘤作了回顾性研究,同期3 079例行输精管切除术,其中8例于术后0.25～4年(平均1.9年)发现睾丸肿瘤。而在同地区、同期的20～59岁人群统计结果,术后睾丸肿瘤预期发生为1.9。作者认为输精管切除术与随后发生的睾丸肿瘤有关,已有人证实在输精管切除后可发生免疫学的及病理生理的影响,Thornhill等也观察到术后睾丸肿瘤发生率有所增高,但是提出在手术时肿瘤有时已经存在。作者认为从手术至肿瘤确诊的间隔看,不太支持在如此短期内发生新的肿瘤。其他学者及四大多中心研究报道手术与发生睾
The incidence of testicular tumors has risen in Scotland over the past 10 years, during which vasectomy has become a more common method of contraception. In this paper, we retrospectively reviewed 37 cases (under 60 years old) diagnosed as testicular tumors in a hospital from 1977 to 1987. During the same period, 3,079 cases underwent vasectomy, of which 8 cases were treated with 0.25 to 4 years (average, 1.9 years) Testicular tumor found. In the same area, the same period of 20 to 59-year-old population statistics, postoperative testicular cancer is expected to occur 1.9. The authors conclude that vasectomy is associated with a subsequent testicular tumor. It has been demonstrated that immunologic and pathophysiological effects can occur after vasectomy. Thornhill et al. Also observed an increase in the incidence of postoperative testicular tumors, however, Tumors sometimes already exist. The author believes that from surgery to tumor diagnosis interval, less support for such a short period of time new tumors. Other scholars and four major centers reported surgery and testis
