概括
在柔性尿路透镜检查过程中,直接透视吸收 (DISS) 有效地降低了内压力 (IRP). 仅为一秒钟激活吸气可显著降低压力,特别是更大的9.2Fr范围,有助于更安全的程序.
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
- 医疗器械技术 医疗器械技术
背景情况:
- 内压力 (IRP) 是尿路检查过程中的关键因素.
- 管理IRP对于患者的安全和预防脏并发症至关重要.
- 灵活的尿道镜和尿道接入 (UAS) 是常用的,但它们对IRP的影响需要评估.
研究的目的:
- 评估直接在视野吸入 (DISS) 对内压力 (IRP) 的影响.
- 为了比较两种不同的柔性尿道镜尺寸 (7.5Fr和9.2Fr) 对IRP的影响.
- 为了评估各种尿路接入 (UAS) 尺寸与DISS结合的影响.
主要方法:
- 一个ex-vivo猪脏模型被用于压力测量.
- 测试了两个灵活的尿管镜 (7.5Fr与3.6Fr工作通道,9.2Fr与5.1Fr工作通道).
- 采用了多种UAS尺寸 (9.5/11.5Fr,11/13Fr,12/14Fr) 和灌压力 (40-100 mmHg),使用和不使用主动DISS.
主要成果:
- 较大的9.2Fr尿管镜在100mmHg灌下产生更高的基线IRP (高达23mmHg),而不是7.5Fr范围 (高达7mmHg).
- 一秒钟的活跃DISS显著降低了IRP从20-23mmHg到3mmHg (9.2Fr范围在100mmHg) 和其他测试设置中的0mmHg.
- 9.2Fr范围表现出比7.5Fr范围 (10-32秒) 更快的压力恢复时间 (8-14秒).
结论:
- 9.2Fr柔性尿道镜与7.5Fr范围相比,与更高的内压力有关,无论UAS大小和灌设置如何.
- 一秒钟激活DISS可以快速而实质性地减少IRP.
- 9.2Fr范围的更广泛的工作道提高了DISS的有效性,并加快了压力正常化.

Urinary Tract Calculi VI: Surgical Management
46
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography
182
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. Intravenous Urography (IVU)Intravenous...

Urologic Endoscopic Procedure: Cystoscopic Examination
423
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
