作者采用回顾性群组研究的方法对输精管金属环节育术的效果和安全性进行了流行病学评价。共调查了6省2028例受术对象,成功率为99.4％。生命表法分析第60顺序月累积成功率为99.34％。术后6个月内的并发症:切口渗血(0.54％)、精索血肿和阴囊血肿(0.35％)、切口感染(0.74％)、精索炎(0.15％)、附睾炎(0.05％)。远期的并发症和副作用:痛性结节(0.64％)、附辜淤积(2.81％)、阴囊坠痛(0.39％)、附睾精索痛(0.30％)。应用多元Logistic回归分析的结果显示,术后并发症和副作用的发生与术时遇到困难和切开输精管有关,采用大量突击的手术方式或施术者不熟练时,其发生率高。调查数据进一步证实,输精管金属环节育术具有安全、有效、简便、经济的优点,是一种非常有推广价值的男性节育新技术。
The authors used a retrospective cohort study to evaluate the efficacy and safety of vas deferens metatarsal disease. A total of 2028 cases in 6 provinces were investigated, with a success rate of 99.4%. Analysis of life table 60th month cumulative success rate of 99.34%. Postoperative complications within 6 months: incisional bleeding (0.54%), spermatic hematoma and scrotal hematoma (0.35%), incisional infection (0.74%), spermatic cord inflammation (0.15%), epididymitis (0.05% . Long-term complications and side effects: painful nodules (0.64%), noxious deposition (2.81%), scrotal pain (0.39%) and epididymal sphincter (0.30%). The results of multivariate Logistic regression analysis showed that the incidence of postoperative complications and side effects were related to the difficulty of operation and incision of vas deferens. The use of a large number of assault surgery or unskilled practitioners, the high incidence. Survey data further confirmed that the vas deferens metal ring surgery has the advantages of safe, effective, simple and economical, is a very promotional value of male birth control new technologies.
