Summary

This study compares two common procedures—RIRS (a scope through the urinary tract) and ESWL (shock waves from outside the body)—to see which removes small kidney stones (up to 1.5 cm) in the lower part of the kidney more effectively. About 66 adults aged 18 to 60 with these stones will be randomly assigned to one treatment. The main goal is stone clearance, and researchers will also track side effects like infection and blood in urine.
