Summary
This study tests whether placing the numbing drug bupivacaine into the bladder after kidney stone surgery can reduce pain and bladder spasms. About 116 adults will be randomly assigned to receive either the drug or a saltwater placebo. The goal is to see if this simple step improves comfort and speeds discharge from the hospital.
