Shock waves vs. scope: a Head-to-Head battle for kidney stone relief
Disease control CompletedThis trial compares two common procedures for treating upper ureteric stones: extracorporeal shock wave lithotripsy (ESWL), which uses external shock waves to break the stone, and semirigid ureteroscopy, where a thin scope is passed through the urinary tract to fragment the stone…
