ClinConnect Summary

The PRAISE study is a prospective registry at University Hospital Ghent in Belgium that will follow adults undergoing treatment for kidney or ureter stones. The researchers want to find out which way of measuring the size of the stone best predicts how well treatment works. They will compare three methods using your pre-treatment CT scan: simple one-dimensional size, surface area, and three-dimensional volume. The study itself doesn’t test a new drug or device; it collects data during standard care to see which measurement best predicts outcomes like whether the stones are cleared after treatment, how long the procedure takes, and whether there are any complications.

If you are eligible, you would be 18 or older and planning a common stone treatment such as extracorporeal shockwave lithotripsy, ureterorenoscopy, or percutaneous nephrolithotomy, and you must have a pre-operative CT scan that can be used for analysis. Participation doesn’t change your treatment plan—the CT measurements are done as part of the study, and you’ll have follow-up checks after treatment to assess stone clearance and record any complications within 30 days. The study is currently enrolling by invitation and is expected to continue collecting data through 2028.
