概括
碎片化激光石术在儿科尿路结石中提供更高的无石率,但需要更长的手术时间. 粉尘处理提供了更短的程序,使得这两种技术都适合于特定情况下.
科学领域:
- 儿科泌尿外科 儿科泌尿外科
- 内分泌病学 在内分泌病学.
- 激光手术 激光手术是一种激光手术.
背景情况:
- 儿科尿路结石的发病率不断增加,需要评估最佳治疗方法.
- 荷尔:YAG (Ho:YAG) 激光石术是儿科尿路结石的关键方式.
研究的目的:
- 为了比较激光除尘与碎片化技术的结果,使用Ho:YAG激光光在患有尿路结石的儿童中.
主要方法:
- 对100名患有尿路结石 (5-20毫米) 的儿童 (<18岁) 进行前性随机研究.
- 两个组:A组 (除尘:0.2-0.6 J,20-40 Hz) 和B组 (碎片化:0.8-1.5 J,10-15 Hz).
- 估计无石头率 (SFR),手术时间和并发症.
主要成果:
- 碎片化组 (B) 的SFR显著更高 (86%对66%),但操作时间更长.
- 在碎片化组中,使用篮子是强制性的,并预测了无石头状态 (p=0.035).
- 两组之间并发症,再治疗或尿道损伤率没有显著差异.
结论:
- 粉尘和碎片都是安全有效的小儿尿镜性石.
- 碎片化产生更高的SFR,以牺牲增加操作时间和强制使用篮子为代价.
- 粉尘提供更短的程序;选择取决于临床因素,如败血症状况.

Urinary Tract Calculi VI: Surgical Management

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...

Urinary Tract Calculi III: Medical Management

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)...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

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.

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...

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,...

Urinary Tract Calculi I: Introduction
386
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...
