The symptoms of urethral stricture are non-specific and may overlap with other common conditions that can confound diagnosis. Urologists play a key role in the initial evaluation of urethral stricture, currently provide all accepted treatments, and must be familiar with the evaluation, diagnostic tests, and surgical treatments for urethral stricture.
A systematic review of the literature using the Pubmed, Embase, and Cochrane databases (search dates January 1, 1990 to January 12, 2015) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of urethral stricture in men. The review yielded an evidence base of 250 articles after application of inclusion/exclusion criteria. The search for the 2023 Amendment was modified to included females and males (search dates December 2015-October 2022 for males; January 1990-October 2022 for females) and a new Key Question on sexual dysfunction was added (search dates: January 1990-10/2022). After inclusion and exclusion criteria were applied, 81 studies were added to the existing evidence base.
Once a urethral stricture is diagnosed, clinicians should determine the length and location of the stricture in order to inform treatment. After a period of urethral rest, patients with short (<2cm) bulbar urethral stricture may be treated endoscopically. Urethroplasty may be performed by an experienced surgeon in patients with first time or recurrent anterior and posterior urethral strictures. The best treatment option for urethral stricture in female patients is urethroplasty using oral mucosa grafts or vaginal flaps rather than endoscopic treatment.
This guideline provides evidence-based guidance to clinicians and patients regarding how to recognize symptoms and signs of a urethral stricture/stenosis, carry out appropriate testing to determine the location and severity of the stricture, and recommend the best options for treatment. The most effective approach for a particular patient is best determined by the individual clinician and patient in the context of that patient's history, values, and goals for treatment.
尿道狭窄的症状不具有特异性,可能与其他常见疾病相重叠,从而导致诊断困难。泌尿科医生在尿道狭窄的初步评估中发挥着关键作用,目前提供所有公认的治疗方法,并且必须熟悉尿道狭窄的评估、诊断测试和手术治疗。
对 Pubmed、Embase 和 Cochrane 数据库进行了系统的文献回顾(检索日期为 1990 年 1 月 1 日至 2015 年 1 月 12 日),以确定与男性尿道狭窄诊断和治疗相关的同行评议文献。在应用纳入/排除标准后,该研究得到了 250 篇文章的证据基础。2023 年修正案的检索进行了修改,纳入了男性和女性(男性检索日期为 2015 年 12 月至 2022 年 10 月;女性检索日期为 1990 年 1 月至 2022 年 10 月),并增加了一个关于性功能障碍的新关键问题(检索日期:1990 年 1 月至 10/2022 年)。在应用纳入和排除标准后,将 81 项研究纳入现有的证据基础。
一旦诊断出尿道狭窄,临床医生就应该确定狭窄的长度和位置,以便为治疗提供依据。在尿道休息一段时间后,短(<2cm)球部尿道狭窄的患者可以进行内镜治疗。对于首次发生的前尿道和后尿道狭窄或复发性狭窄的患者,有经验的外科医生可以进行尿道成形术。对于女性患者,尿道狭窄的最佳治疗选择是使用口腔黏膜移植物或阴道皮瓣进行尿道成形术,而不是内镜治疗。
本指南为临床医生和患者提供了关于如何识别尿道狭窄/梗阻症状和体征、进行适当的检查以确定狭窄的位置和严重程度以及推荐最佳治疗方案的循证指导。对于特定患者,最佳治疗方法最好由个别临床医生和患者根据患者的病史、价值观和治疗目标来确定。
