摘要

背景:即使存在潜在的风险因素和局限性,逆行尿道造影术(RGU)仍是评估前尿道狭窄最常用的成像方式。尿道声学造影(SUG)是近几年开始使用的一种有效的成像方式,它可以评估前尿道狭窄而不存在这些风险,但由于其复杂性,目前仍不太流行。这项前瞻性研究旨在比较 SUG 与 RGU 的评估结果,并分析 SUG 与 RGU 的评估结果对手术决策的影响:方法: 用 RGU 评估了 30 名前尿道狭窄患者的狭窄位置、长度和相关尿道病变,并制定了相应的手术计划。之后,所有患者都接受了 SUG 重新评估,将结果与 RGU 的结果进行比较,并考虑 RGU 和 SUG 的结果重新制定手术计划。所有结果均与手术结果进行了比较:SUG、RGU 和手术的平均狭窄长度分别为 20.45 毫米、17.15 毫米和 20.38 毫米。SUG 对实际狭窄长度预测的总体敏感性和特异性分别为 92.3% 和 96.1%,而 RGU 的敏感性和特异性分别为 78.9% 和 85.1%。海绵状纤维化仅通过 SUG 进行评估,准确率为 85%-90%。在考虑 SUG 和 RGU 结果的情况下,31% 的病例改变了手术方案:结论:SUG 被认为是测量狭窄长度更精确的方法,在提供更多关于海绵体纤维化程度以及病变尿道和尿道周围组织的相关病理知识方面更具信息性和详细性。为了更好地制定前尿道狭窄的术前计划,SUG 应与 RGU 一起加入术前检查。

Impact of Adding Urethral Sonography with Retrograde Urethrography in Preoperative Assessment of Anterior Urethral Stricture.

Background: Even with underlying risk factors and limitations, retrograde urethrography (RGU) is the most popular imaging modality in the assessment of anterior urethral stricture. Urethral sonography (SUG) is an able imaging modality in use for the last few years which evaluates anterior urethral stricture without these risks, though it is still not much popular due to its complexity. This prospective study was designed to compare the assessment made on SUG with the results of RGU and to analyze its impact on surgical decision-making when the results of SUG were taken into consideration with RGU.

Methods: Thirty patients with anterior urethral stricture were assessed for stricture location, length, and associated urethral pathologies with RGU and surgery planned accordingly. Later, all were reevaluated with SUG, results compared with that of RGU and surgery replanned, considering both RGU and SUG findings. All results were compared with operative findings.

Results: The mean stricture lengths on SUG, RGU, and surgery were 20.45 mm, 17.15 mm, and 20.38 mm, respectively. Overall sensitivity and specificity of SUG in actual stricture length prediction were 92.3% and 96.1%, whereas these were 78.9% and 85.1%, respectively, on RGU. Spongiofibrosis was assessed only with SUG, that too, with 85%-90% accuracy. Surgical plan was changed in 31% of cases when SUG findings were taken into account along with RGU findings.

Conclusion: SUG was found more precise modality in the measurement of stricture length and more informative and elaborative in providing added knowledge of degree of spongiofibrosis and associated pathologies of diseased urethra and periurethral tissue. For better preoperative planning of anterior urethral strictures, SUG should be added to work-up along with RGU.

期刊介绍: The Journal of Medical Ultrasound is the peer-reviewed publication of the Asian Federation of Societies for Ultrasound in Medicine and Biology, and the Chinese Taipei Society of Ultrasound in Medicine. Its aim is to promote clinical and scientific research in ultrasonography, and to serve as a channel of communication among sonologists, sonographers, and medical ultrasound physicians in the Asia-Pacific region and wider international community. The Journal invites original contributions relating to the clinical and laboratory investigations and applications of ultrasonography.
