Rirs Lower Pole Renal Stones Stone Free Rate Ureteral Access Sheath Flexible Negative Pressure Lateral Position

ClinConnect Summary

This clinical trial is studying how different body positions and a special tool called a flexible negative pressure suction ureteral sheath (f-UAS) can help improve the treatment of kidney stones, specifically those located in the lower part of the kidney. The researchers want to find out if changing the patient's position during a procedure called retrograde flexible ureteroscopy (RIRS) can lead to better outcomes, meaning a higher chance of completely removing the stones.

To participate in the trial, you must be an adult aged between 18 and 80 years who has a lower pole kidney stone measuring between 10 and 20 millimeters. Certain health conditions, such as having a narrow ureter or being pregnant, may exclude you from the study. If you join, you can expect to be randomly assigned to different treatment groups to see how well each method works. This trial aims to find the most effective way to help patients become stone-free after treatment.
