概括

吸管尿管接入罩 (S-UAS) 提高了即时无石头率,并减少了逆行性内手术 (RIRS) 中的辅助程序. 这种最少的侵入性技术增强了石块的去除能力,比传统的尿道接入 (UAS) 有潜在的优势.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
最少侵入性的手术
腎石病的管理方法

背景情况:

逆行性内手术 (RIRS) 是对脏和上尿路结石的关键技术.
尿道接入 (UAS) 有助于RIRS,但它们对无结石率 (SFR) 的影响仍有争议.
吸管尿管接入 (S-UAS) 提供了增强的灵活性和石头去除能力.

研究的目的:

在RIRS程序中比较传统UAS与S-UAS的疗效.
评估S-UAS对无石头率,操作参数和并发症的影响.
评估石材特性对不同UAS类型的RIRS结果的影响.

主要方法:

对104名接受RIRS的患者进行了回顾性队列研究.
传统UAS (n=53) 和S-UAS (n=51) 组之间的比较.
分析基线特征,操作时间,SFR,并发症和辅助程序.

主要成果:

在S-UAS组中,立即SFR显著增加 (82.0%与60.4%,p=0.016).
S-UAS组需要的辅助手术较少 (5.9%与22.6%,p=0.015) 和较高的SFR下方玻璃杯石头.
手术时间,住院时间和并发症率在各组之间相似.

结论:

S-UAS增强了即时的SFR,并减少了RIRS中的辅助程序的需要.
该设备有助于有效的石块疏散,而不会增加并发症.
S-UAS显示出有前途的结果,特别是在特定的石材负载方面;建议进行进一步的前性研究.

关键词:

逆行性内外科手术 (RIRS) 是一种手术.没有石头的价格 (SFR)吸管尿管接入 (S-UAS) 的使用方法传统的尿道接入 (UAS)

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
