Comparing two procedures for 2-4cm kidney stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial compares two methods to remove kidney stones that are 2-4 cm in size: one uses a thin tube through a small cut in your back (VISOR), and the other uses a larger cut (PCNL). The goal is to see which approach works better and has fewer side effects.
