Resumen
La terapia extracorpórea de ondas de choque piezoeléctricas ofrece una opción no quirúrgica segura y efectiva para los cálculos salivales. Este tratamiento mínimamente invasivo fragmentó con éxito las piedras en el 88% de los pacientes, proporcionando alivio y limpieza de piedras.
Área de la Ciencia:
- Urología Urología Urología.
- La otorrinolaringología otorrinolaringología.
- Tecnología médica Tecnología médica.
Sus antecedentes:
- La extirpación quirúrgica de la glándula es tradicional para la sialolitiasis refractaria.
- Se buscan técnicas mínimamente invasivas para los cálculos salivales.
- La litotripsia extracorporal por ondas de choque (ESWL, por sus siglas en inglés) es prometedora para los cálculos salivales.
Objetivo del estudio:
- Evaluar la seguridad y eficacia del ESWL piezoeléctrico para cálculos salivales.
- Para evaluar los resultados en pacientes inadecuados para el tratamiento conservador.
Principales métodos:
- 51 pacientes con cálculos salivales sintomáticos se sometieron a ESWL.
- Los tratamientos fueron guiados por ecografía, con hasta 3 sesiones por paciente.
- Se monitoreó la fragmentación de la piedra y los resultados clínicos.
Principales resultados:
- La fragmentación completa de la piedra (≤3 mm) se logró en el 88% de los pacientes.
- El 90% experimentó alivio de la incomodidad; el 53% estaba libre de piedras a las 20 semanas.
- Se observaron tasas de aclaramiento más altas para las piedras parótidas (81%) frente a las submandibulares (40%).
Conclusiones:
- El ESWL piezoeléctrico es un tratamiento mínimamente invasivo seguro, cómodo y efectivo para los cálculos salivales.
- Reduce la necesidad de cirugía y procedimientos auxiliares.
- Se justifica una mayor investigación sobre los resultados específicos de las glándulas.

01:15Quarrying of Stone
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the block.

01:23Abrasion Resistance of Concrete
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

01:28Urinary Tract Calculi I: Introduction
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...
01:30Urinary 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)...
01:27Urinary Tract Calculi IV: Nutrition Therapy and Prevention
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,...
01:25Urinary 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...
