Background and study aims
This study aims to find out if changing the direction of a double-j stent placed in the ureter can reduce the uncomfortable urinary symptoms that patients often experience. The researchers want to see if turning the tip of the stent outward instead of inward makes a difference.
Who can participate?
Patients who have undergone a procedure called ureteroscopy for kidney or ureteral stones and have had a double-j stent inserted can participate in this study.
What does the study involve?
Participants will be divided into two groups based on the direction of their ureteral stent. They will fill out a questionnaire about their symptoms before and after the treatment. The researchers will compare the results to see if there is a difference between the two groups.

The possible benefit of participating is that it may help identify a better way to place stents that reduces urinary symptoms. The risks are minimal and are mainly related to the standard procedure of having a stent placed.
