At city hospital’s Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive procedure used to treat kidney stones. It uses focused shock waves to break stones into smaller fragments, making them easier to pass naturally through the urinary tract. Performed on an outpatient basis, ESWL is guided by imaging and requires minimal recovery time. Common side effects include mild discomfort and blood in the urine, but serious complications are rare.
