Extracorporeal Shock Wave Lithotripsy Uses High-Energy Shock Waves To Break Up Kidney Stones And Fragments

 

Extracorporeal Shock Wave Lithotripsy

Extracorporeal Shock Wave Lithotripsy (ESWL) is a noninvasive procedure that breaks up kidney stones into smaller pieces. It is done under local, regional or general anesthesia and is less invasive than surgery. It can be performed in the office with a machine called a lithotripter. This is a machine that generates shock waves and is focused on the kidney stone or stones using X-ray or ultrasound. The shock waves break up the stones into small particles that can pass spontaneously in urine. This treatment can significantly reduce the need for surgical procedures. It also reduces hospital stays and costs.

Doctors may recommend Extracorporeal Shock Wave Lithotripsy as part of the treatment plan in case of a large or very hard kidney stone that is blocking the flow of urine or causing pain or severe discomfort. It can also be used to treat smaller stones that are stuck in the ureter.

This procedure is safe for most people, as there are some restrictions and precautions. The procedure cannot be performed for pregnant patients as the shock waves and X-rays could harm the fetus.

The lithotripsy procedure is usually done by a urologist who is a medical specialist in the urinary tract. They will recommend a treatment depending on a number of factors, such as the size and location of kidney stone or stones, age and general health, any other medical conditions.

Many people experience pain when kidney stones form and then move through the urinary tract. If the kidney stone is large or if it becomes stuck in a ureter this can cause health problems and may require surgery to remove the stone. Kidney stone treatment with shock wave lithotripsy can break the stones into small pieces so they can pass through the body more easily. It can also help reduce symptoms and prevent complications caused by the passing of kidney stones.

During Extracorporeal Shock Wave Lithotripsy, the shock waves are delivered through a lithotripter that is equipped with a coupling agent and an electrode. The lithotripter uses an electromagnetic generator, electrohydraulic or piezoelectric, to produce shock waves. The shock waves are delivered to the lithotripsy site through the coupling agent, which is a medium that is acoustically similar to the body and therefore does not interact with tissues that have a different acoustic impedance, such as stones. Depending on the type of lithotripsy machine, shock wave generators are either electrohydraulic or piezoelectric.

Dornier MedTech gained approval from CE and the US FDA for their new Nautilis urology table, in May 2022. The Nautilus has reimagined the urology table with keeping the patients, hospitals and the urologist in mind.

With the use of High-Frequency alternating current, Radiofrequency Ablation Device convert Electromagnetic Energy into Heat Energy

Image
Radiofrequency Ablation Device RFA is a minimally invasive technique that may be done in a doctor's office or a hospital. The majority of patients are able to return home the same day. RFA can be done with or without minimal sedation. If anaesthesia is utilised, the patient is generally kept awake and alert enough to explain what they are feeling during the nerve stimulation and lesioning. The following are the steps involved in an RFA: ·         On a procedure table, the patient is lying on his or her stomach. An intravenous (IV) line is established if sedation is utilised so that relaxation medication (sedation) can be administered. ·         To reduce the danger of infection, the skin above the treatment region (neck, mid-back, or low back) is thoroughly washed. ·         A numbing drug (anaesthetic) is injected into the location of the RFA injection site to numb a small patch of skin. Radiofrequency ablation is a process that is reasonably safe and low-risk. Some pati

Air Purifier works as a Sanitizer in the air which helps in reducing pollutants, allergens, and toxins

Image
  Air purifier   Within a confined area, an air purifier eliminates organic and inorganic impurities from the air. The clean air is sent out into the living space after these devices catch pollutants and particles in the air. Dust mites, mould spores, chemicals, poisons, and scents are all trapped by these filters. These gadgets are frequently touted as appropriate tools for asthmatic patients and others who suffer from airborne allergen allergies. An indoor Air purifier ensures the filtering of the air inside a closed room, which it catches and releases as clean air. If the windows may be opened, it functions in addition to the necessary natural ventilation. A contrast must be noted between a professional model and a residential device, since neither provides the same level of air treatment or overall performance. Pollens, fine particles PM2.5 and PM10, VOCs (Volatile Organic Compounds), viruses, and germs are all effectively removed by a professional air purifier with a HEPA 13 or

The Isocyanates Market to Witness Robust Growth in North America and Asia Pacific

Image
  Organic compounds that contain an isocyanate group are referred to as isocyanates. They are a family of highly reactive, low molecular weight chemicals. Isocyanates are extensively used in the automobile, electronics, and construction industry. Moreover, they are used in a variety of industries using chemicals such as certain coatings/linings, adhesives, lacquers, two pack spray paints, and in foam production such as fillers or insulation. Isocyanates are also used in the production of rigid foams, coatings, elastomers, and adhesives. Increasing demand form the construction industry due to its highly reactive chemical property is expected to be a key factor driving the Isocyanates market growth. Among regions, the Isocyanates M arket is witnessing robust growth in North America and Asia Pacific due to the rapid growth of various end-use industries such as automotive, electronics, and construction, with India, China, and the U.S. being the major growth engines.
