A chronic outcome of shock wave lithotripsy is parenchymal fibrosis.

Summary of "A chronic outcome of shock wave lithotripsy is parenchymal fibrosis."

Shock wave lithotripsy (SWL) is widely viewed as an effective noninvasive method to break stones within the kidney and ureter. However, it is a technology that is not without trauma to the kidney-acute vascular, tubular and interstitial damage is often reported that if severe enough can lead to renal fibrosis (scarring) and permanent loss of functional parenchyma. These chronic changes can potentially lead to serious long-term adverse effects. The risk of developing chronic fibrotic lesions after lithotripsy is influenced by the number of shock waves (SWs) administered, SW power, rate of SW delivery and the number of SWL treatment sessions. The interplay between these risk factors is largely unknown, but progress has been made in identifying SWL protocols and pharmacologic therapies that can ameliorate the acute and chronic tissue damage that is an unintended consequence of SWL treatment.

Medical and Biotech [MESH] Definitions

The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.

Sudden, violent, and often destructive expansion of gases which propagates energy outward, such as a shock wave, ejecting fragments and debris at high velocities.

An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

A slowly progressive condition of unknown etiology, characterized by deposition of fibrous tissue in the retroperitoneal space compressing the ureters, great vessels, bile duct, and other structures. When associated with abdominal aortic aneurysm, it may be called chronic periaortitis or inflammatory perianeurysmal fibrosis.

A condition in which the hepatic venous outflow is obstructed anywhere from the small HEPATIC VEINS to the junction of the INFERIOR VENA CAVA and the RIGHT ATRIUM. Usually the blockage is extrahepatic and caused by blood clots (THROMBUS) or fibrous webs. Parenchymal FIBROSIS is uncommon.
