概括
这项研究比较了CVAC 2.0系统和灵活和可导航的尿道接入罩 (FANS) 用于结石去除. 两种系统都实现了高石材清除率,CVAC 2.0显示较大的石材清除率更好,剩余体积没有增加.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 内分泌病学 在内分泌病学.
- 医疗器械 医疗器械
背景情况:
- 结石对健康造成重大负担.
- 尿路透镜是对结石的常见治疗方法.
- 优化石头清除和尽量减少并发症是尿路透镜的关键目标.
研究的目的:
- 为了比较石头清除,无石头率,和 CVAC 2.0 系统和灵活和可导航的尿道接入罩 (FANS) 之间的并发症,在结石灵活尿道显微镜期间.
- 为了评估这些系统在管理不同石头负担方面的有效性.
主要方法:
- 一项前性研究涉及123名接受结石柔性尿路透镜检查的患者.
- 人口统计,手术内数据,石头清除 (体积和单维) 和并发症的比较.
- 使用非对比CT进行石材评估和Pearson相关性进行石材体积分析.
- 对手术前石头负担>1.5厘米的患者的子分析.
主要成果:
- 与FANS组相比,CVAC 2.0组具有更大的初始石块体积,但实现了更大的绝对石块清除.
- 在不同组中,无石头率相似 (90%的CVAC 2.0与81%的FANS).
- 与FANS不同的是,CVAC 2.0显示石头>1.5厘米的石头相对石头清除幅度显著增加,并且没有显示剩余石头体积显著增加,而预手术石头负担更大.
结论:
- 无论是FANS还是CVAC2.0,都能达到超过95%的结石石的石头清除率,即使初始负担很大.
- CVAC 2.0 系统可以通过保持清除效率和防止增加剩余结石负担,在管理较大的结石方面提供优势.
- 进一步的研究可能会阐明每个系统的长期结果和具体指示.

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...

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...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

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.

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

391
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
