概括
亚临床乳头化病变 (PCL) 在没有结石的脏中很常见,并且与尿量低和高血压等因素有关. 针对尿液化学和血管健康的早期干预可以防止结石的形成.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 矿物质的新陈代谢.
背景情况:
- 包括兰德尔斑块和塞在内的亚皮质乳头结是结石形成的已知前体.
- 然而,在没有石头疾病史的人群中,它们的患病率和相关因素尚未得到充分理解.
研究的目的:
- 为了调查未经结石的脏中亚临床乳头结石的存在.
- 确定与这些结相关的尿路和临床风险因素,假设与石头形成者相似.
主要方法:
- 50个脏的回顾性分析从癌症接受脏切除的患者,不包括那些先前患有石头疾病或特定补充剂/疾病.
- 进行了高分辨率的微计算断层扫描 (微CT) 来量化矿物与外围细胞 (M/P) 的比例,并进行了骨质素 (OPN) 免疫组织化学.
- 临床相关的乳头尖结病变 (PCLs) 被定义为≥1 mm3.
主要成果:
- 临床相关的PCL在46%的石头脏中被发现.
- 与PCL阴性患者相比,PCL阳性患者年龄较大,高血压更频繁,尿液体积较低,尿酸酸盐含量较低,尿液特异性重量较高.
- 亨勒环中增加的OPN染色与矿物质负担相关,多变量分析确定尿量低,尿高和高血压是PCL的独立预测因素.
结论:
- 亚临床的乳头结在以前没有结石的脏中很普遍,并与特定的尿路 (体积低,含量高) 和全身 (高血压) 风险因素相关.
- 这些发现表明,专注于尿液成分和血管健康的早期干预可能会减轻矿物沉积并延迟结石的出现.

345
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

01:28Urinary Tract Calculi I: Introduction
371
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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

337
Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

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)...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
