ClinConnect Summary

This clinical trial is looking at two different ways to use a special laser to treat kidney and ureteral stones, which are hard deposits that can cause pain and blockages in the urinary system. The study compares a new laser technology called Moses 2.0, which can operate in two different modes (with or without pulse modulation), to see which method works better and is more efficient in the operating room. Researchers want to find out how long the procedures take, how much laser energy is used, and how effective each method is at completely removing the stones.

To participate in this trial, you should be between 65 and 74 years old and have kidney or ureteral stones that are at least 8 mm but less than 20 mm in size. You must be scheduled for a procedure called ureteroscopy, where doctors use a small camera and tools to remove the stones. It’s important that you are willing to sign consent forms to participate. However, people under 18, those with certain kidney conditions, or those needing special considerations cannot join. If you qualify, you will have the chance to help researchers learn more about advanced laser treatments for kidney stones, which could improve care for future patients.
