Summary

This trial tests a new technique to help break up kidney stones without surgery.

Who is the study for?
This trial is for adults who can consent to treatment, have kidney stones between 8-20 mm in size suitable for ureteroscopy, and meet specific health guidelines. It's not open to those with neurogenic bladder conditions, spinal cord injuries, pregnancy, untreated UTIs or a history of certain urinary tract procedures.
What is being tested?
The study is evaluating the effectiveness of Thulium Fiber Laser (TFL) technology in breaking down kidney stones during ureteroscopy—a procedure where a small scope is used to locate and remove stones from the urinary tract.
What are the potential side effects?
While the side effects are not detailed here, typical risks associated with laser lithotripsy may include discomfort during urination, bleeding around the stone fragments, and possible infection.
