概括
具有负压吸收尿路接入罩 (UAS) 的灵活尿路透镜 (fURS) 可以在通风口关闭时显著降低内压力. 这一发现为优化fURS程序和改善患者结果提供了机械洞察力.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 生物医学工程 生物医学工程
背景情况:
- 灵活尿道透视 (fURS) 是治疗脏和尿道结石的标准.
- 尿道接入 (UAS) 改善石头清除,但它们对内压力的影响需要进一步研究.
研究的目的:
- 系统地评估真空吸气UAS在fURS期间调节内压力的有效性.
- 为优化fURS程序提供机械洞察力.
主要方法:
- 采用了使用3D打印的体外柔性尿路透镜模型.
- 使用8.6Fr尿管望远镜测量了内压力,在三个UAS配置下进行测量:常规,负压与开放的通风,负压与关闭的通风.
- 在各种UAS大小和灌压力 (10-240 mmHg) 上进行了实验.
主要成果:
- 与传统的无人机和开放式风口配置相比,带有封闭风口的负压UAS显著降低了内尿道压力 (p < 0.01).
- 较大的UAS尺寸与明显较低的内压力相关 (p < 0.01).
- 与传统无人机系统相比,开放通风负压UAS只显示了轻微的,不显著的压力降低 (p = 0.56).
结论:
- 在尿路透镜检查期间的内压力随着灌压力增加而增加.

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.

3.3K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
