为了阐明输精管结扎术后附睾瘀积综合征的发病机制，探讨诊断与治疗方法，收集１０例病人，行血清及精浆抗精子抗体测定及Ｂ超、Ｃ超、ＭＲＩ等项硷查。手术采用附睾一近睾端输精管。结扎结节整块切除术。术中取附睾液行细菌培养及睾丸活检，标本行光镜和电镜检查。术后随访，９例治愈，１例无效。瘀积附睾的组织学检查表明是附睾对外漏精子的无菌性炎症反应。睾丸活检，生精过程正常２侧，其同侧结扎断端有精子肉芽肿形成，提示输精管结扎断端精子肉芽肿的形成对睾丸有保护作用。
To clarify the pathogenesis of epididymal stasis syndrome after vasectomy, the diagnosis and treatment methods were explored. Ten patients were collected for anti-sperm, serum and seminal plasma anti-sperm antibodies and B, C and MRI. Surgical use of a proximal epididymal vas deferens. Ligation nodules block resection. Intraoperative epididymal bacteria culture and testicular biopsy specimens were light microscopy and electron microscopy. Follow-up postoperatively, 9 cases were cured, 1 case was ineffective. Histological examination of stubborn epididymis showed aseptic inflammatory response of the epididymis to sperm leakage. Testicular biopsy, spermatogenesis normal 2 side, its ipsilateral ligation sperm granuloma formed, suggesting that the formation of the spermatic granuloma vasectomy ligament protective effect on the testis.
