The purpose of this guideline is to provide guidance to clinicians who offer vasectomy services.
A systematic review of the literature using the search dates January 1949-August 2011 was conducted to identify peer-reviewed publications relevant to vasectomy. The search identified almost 2,000 titles and abstracts. Application of inclusion/exclusion criteria yielded an evidence base of 275 articles. Evidence-based practices for vasectomy were defined when evidence was available. When evidence was insufficient or absent, expert opinion-based practices were defined by Panel consensus. The Panel sought to define the minimum and necessary concepts for pre-vasectomy counseling; optimum methods for anesthesia, vas isolation, vas occlusion and post-vasectomy follow up; and rates of complications of vasectomy. This guideline was peer reviewed by 55 independent experts during the guideline development process.
Vas isolation should be performed using a minimally-invasive vasectomy technique such as the no-scalpel vasectomy technique. Vas occlusion should be performed by any one of four techniques that are associated with occlusive failure rates consistently below 1%. These are mucosal cautery of both ends of the divided vas without ligation or clips (1) with or (2) without fascial interposition; (3) open testicular end of the divided vas with MC of abdominal end with FI and without ligation or clips; and (4) non-divisional extended electrocautery. Patients may stop using other methods of contraception when one uncentrifuged fresh semen specimen shows azoospermia or ≤ 100,000 non-motile sperm/mL.
Vasectomy should be considered for permanent contraception much more frequently than is the current practice in the U.S. and many other nations. The full text of this guideline is available to the public at http://www.auanet.org/content/media/vasectomy.pdf.
本指南旨在为提供输精管切除术服务的临床医生提供指导。
对 1949 年 1 月至 2011 年 8 月的文献进行了系统评价,以确定与输精管切除术相关的同行评议出版物。搜索确定了近 2000 个标题和摘要。应用纳入/排除标准产生了 275 篇文章的证据基础。当有证据时,定义了输精管切除术的循证实践。当证据不足或不存在时,通过小组共识定义了基于专家意见的实践。小组试图定义输精管切除术术前咨询的最低和必要概念;最佳的麻醉、输精管隔离、输精管阻塞和输精管切除术后随访方法;以及输精管切除术的并发症发生率。本指南在指南制定过程中由 55 名独立专家进行了同行评审。
输精管隔离应使用微创输精管切除术技术进行,例如无刀输精管切除术技术。输精管阻塞应通过四种技术中的任何一种进行,这四种技术的闭塞失败率始终低于 1%。这些技术包括:(1)不结扎或夹闭分离的输精管两端的粘膜烧灼,或(2)不结扎或夹闭带筋膜间置;(3)开放分离的输精管睾丸端,用 MC 处理腹部端并带 FI,不结扎或夹闭;(4)非分割扩展电灼。当一份未经离心的新鲜精液标本显示无精子症或每毫升非运动精子数≤100,000 时,患者可以停止使用其他避孕方法。
输精管切除术应被视为永久性避孕方法,其应用频率应远高于美国和许多其他国家目前的实践。本指南的全文可在 http://www.auanet.org/content/media/vasectomy.pdf 上向公众提供。
