Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive procedure primarily utilized for treating kidney or ureter stones. Administered under general anesthesia, ESWL involves using X-ray guidance to locate the stone, followed by the application of targeted external shocks. These shocks effectively pulverize the stone into minuscule particles resembling sand, facilitating their natural passage through urine. Typically performed as an outpatient procedure, patients are discharged with a strainer to collect any stone fragments expelled post-treatment, which are to be brought to follow-up visits. Common side effects may include blood in the urine and temporary kidney pain.
