ClinConnect Summary

This clinical trial is studying a new way to help people pass kidney stones using ultrasound technology. Instead of needing anesthesia, the researchers want to see if they can safely break up and move the stones using ultrasound waves. This trial is not yet recruiting participants, but it aims to find out if this method can be an effective treatment for those with certain types of kidney stones.

To be eligible for this trial, participants must be adults between the ages of 65 and 74 who have at least one kidney stone measuring between 2 mm and 7 mm. However, some individuals won't be able to join, such as those under 18, pregnant women, or anyone with specific health issues that might complicate the procedure. If selected, participants can expect to undergo the ultrasound treatment and will need to attend follow-up appointments to monitor their progress. It's an exciting opportunity for those struggling with kidney stones to potentially benefit from a less invasive treatment option.
