输精管结扎术后痛性结节的病理、细菌和免疫学研究

A Study of Pathology, Bacteriology and Immunology about the Painful Nodules Resulted from Vasectomy

本文报道３５例输精管结扎术后痛性结节的研究结果，表明绝大多数痛性结节的病理基础为精子漏出所致精子肉芽肿。它的发生、组织病理学类型、结节大小以及病程长短与抗体的发生率和滴度高低之间没有发现因果关系。细菌感染不是痛性结节产生的原因。

A study on 35 painful nodules (PN) resulted from vasectomy shows that sperm granulomas are microseopically noted in 86.57%(n=31).The present paper shows that the pathological basis of the most PN is sperm granulomas resulted from the leakage of sperm. No relationship is found between the origination, histopathological type, size and duration of PN, and the incidence, and mean titer values of antisperm antibodies. Bacteria infection ig not main cause of PN.
