Comparing two sizes of scopes for kidney stone removal
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two sizes of flexible ureteroscopes (small tubes used to remove kidney stones) to see if a thinner one is just as safe and effective as a slightly thicker one. You might join if you're having a ureteroscopy for small kidney stones.
