ClinConnect Summary

This clinical trial is looking at how two different methods for treating kidney stones work. The study compares a retrograde approach, which involves accessing the kidney through the bladder, to an antegrade approach, which accesses the kidney from the back. Researchers want to find out which method is more effective for patients with larger kidney stones and what factors might help predict treatment success.

To be eligible for this trial, participants need to have kidney stones that are larger than 10 mm in size, confirmed by a special type of imaging called a CT scan. However, individuals with certain conditions, such as kidney infections, previous surgeries on the same kidney, stones located in different parts of the urinary tract, or those who are pregnant or have unusual kidney shapes, cannot participate. The trial is not yet recruiting patients, but when it does, participants can expect to be closely monitored and will help researchers gather important information that may improve future treatments for kidney stones.
