概括
在儿童中,半刚性尿路透镜 (URS) 暂时增加血管阻力,通过升高的电阻指数 (RI),脉动性指数 (PI) 和最大抽缩速度 (PSV) 表示. 较长的操作时间和更多的灌液使这些变化变得更糟.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 儿科泌尿外科 儿科泌尿外科
- 医疗成像医学成像
背景情况:
- 半刚性尿路透镜 (URS) 是儿童结石的常见手术.
- 评估URS后内血动力学变化对于了解恢复至关重要.
- 彩色多普勒超声波 (CDUS) 提供了有价值的非侵入性血管参数.
研究的目的:
- 在儿童半刚性URS后评估术前和术后的内血管参数 (RI,PI,PSV,EDV).
- 为了将这些指数 (ΔRI, ΔPI, ΔPSV, ΔEDV) 的变化与相反的正常脏进行比较.
- 为了确定影响血管阻力在术后变化的因素.
主要方法:
- 对23名接受半刚性URS治疗的儿科患者进行前性分析.
- 在手术前和手术后24小时内进行的术前和术后CDUS.
- 在手术和逆侧脏中评估内RI,PI,PSV和EDV.
主要成果:
- 在手术脏 (p < 0.001) 中观察到RI,PI和PSV的统计显著增加.
- 手术后的变化 (ΔRI, ΔPI, ΔPSV) 在经过手术的脏中明显高于未经手术的脏 (p < 0.05).
- 增加的 ΔRI, ΔPI 和 ΔPSV 与更长的操作时间和更高的灌液体体积相关.
结论:
- 半刚性URS会导致儿童的血管抵抗显著,短期增加.
- 观察到的血液动力学变化 (RI,PI,PSV) 是暂时的.
- 长时间的操作时间和灌液体体积的增加与更大的血液动力学变化有关.

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.

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

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)...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
