Study Summary

This trial compares two laser types for treating kidney stones, to see which is safer and more effective.

Who is the study for?
This trial is for adults over 18 with kidney stones sized 10-20 mm or multiple stones in one calyx. They must understand and consent to the study, be able to follow its procedures, and not have had previous shock wave treatments for the same stone. Pregnant individuals, those with certain preexisting conditions, a solitary kidney, additional ureteral stones or strictures, very large or numerous differently located stones, untreated urinary infections or uncorrected bleeding disorders are excluded.Check my eligibility
What is being tested?
The study compares two laser technologies: Thulium Fiber Laser (TFL) and MOSES Holmium Laser in treating kidney stones. It aims to determine which laser is more effective and safe for patients requiring removal of these stones through ureteroscopy.See study design
What are the potential side effects?
While specific side effects aren't listed here, typical risks from laser treatment of kidney stones may include discomfort during urination, blood in urine post-procedure, potential infection risk due to surgery as well as possible injury to the kidneys or surrounding organs.
