概括
灵活尿路透镜激光光 (FURSL) 期间的内温度 (IRTs) 随着激光功率设置的提高而增加,并且与骨前后直径 (APD) 有反向关系. 避免使用无盖FURSL的高功率设置 (≥20W),特别是在非扩张的骨盆中.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 腎臟病學 (nephrology) 是一種醫學.
- 医疗工程 医疗工程
背景情况:
- 灵活的尿道透镜激光光 (FURSL) 是对结石的常见手术.
- 监测内温度 (IRT) 对于防止FURSL期间的热损伤至关重要.
- 需要进一步研究IRT,激光功率和脏解剖学之间的关系.
研究的目的:
- 在无柔性尿道透镜激光石术 (FURSL) 期间探索内温度 (IRTs).
- 调查IRT与骨前后直径 (APD) 之间的相关性.
主要方法:
- 招募了10名经过FURSL的内置瘤管患者.
- 无盖FURSL进行了引力灌 (23°C) 和K型热电偶通过瘤管插入.
- 在增量功率设置 (5-30 W) 的纤维激光激光激活期间记录了温度,在43°C时停用.
主要成果:
- IRT与激光功率设置直接相关,在更高功率水平 (p < 0.001) 上显著温度升高.
- 在20W的3/10患者和30W的8/10患者中,温度达到43°C.
- IRT与骨APD相反相关;较低的APD (≤20毫米) 在等效功率设置下导致更高的IRT (p <0.001).
结论:
- 在FURSL期间,内温度与激光功率直接相关,与骨APD相反相关.
- 使用功率设置为20W或更高的无FURSL可能会构成热风险,特别是在患有非扩张盆的患者中.
- 需要进一步的研究来确定安全的温度值,并优化FURSL参数,以尽量减少热损伤.

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...
Imaging Studies II: Ultrasonography
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
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. Intravenous Urography (IVU)Intravenous...
Urologic Endoscopic Procedure: Cystoscopic Examination
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...
