Summary
This study compares L-citrulline, an amino acid, to tamsulosin, a standard drug, for helping adults pass kidney stones. 120 people with a single stone in the lower ureter will take one of the two treatments for up to 4 weeks. The main goal is to see which treatment leads to faster stone passage with fewer symptoms.
