Summary

"This trial is comparing two types of lasers, one from Boston Scientific and one from Olympus, to see which one is better for treating medium-to-large kidney stones using a minimally invasive procedure."

Who is the study for?
This trial is for individuals with medium-to-large kidney stones who are candidates for a minimally invasive surgical procedure called mini PCNL. Specific eligibility details aren't provided, but typically participants should be in stable health and meet certain criteria set by the surgeon.
What is being tested?
The study compares two types of lasers used in kidney stone surgery: the Boston Scientific Lumenis Pulse 120H Moses 2.0 holmium laser and the Olympus Soltive Superpulsed thulium fiber laser (TFL). Patients will be randomly assigned to one of these treatments.
What are the potential side effects?
While specific side effects are not listed, typical risks associated with laser kidney stone treatment include bleeding, infection, pain during or after surgery, potential damage to surrounding tissues, and possible need for additional procedures.
