Verified step by step guidance1
Understand the term 'extracorporeal shockwave lithotripsy' (ESWL). It is a medical procedure used to treat kidney stones by breaking them into smaller fragments using high-energy sound waves, allowing them to pass through the urinary tract more easily.
Recognize that ESWL is a non-invasive procedure, meaning it does not require surgical incisions or direct access to the kidney stones through invasive methods.
Eliminate incorrect options by analyzing their descriptions: (1) ESWL does not involve injecting medication to dissolve bladder stones, (2) ESWL is not related to blood filtration or dialysis, and (3) ESWL does not involve surgical removal of the kidney.
Focus on the correct description: ESWL uses sound waves to break up kidney stones, which aligns with the non-invasive nature of the procedure.
Conclude that the best description of extracorporeal shockwave lithotripsy is: 'It is a non-invasive procedure that uses sound waves to break up kidney stones.'
