Initial x-ray image
Kidney stone is located in the center of the x-ray.
About KSR
The Kidney Stone Registry (KSR) is a global clinical database that provides anonymized patient information (e.g., age, BMI), treatment parameters (settings used to fragment stones), and x-ray images of shockwave lithotripsy (SWL) and laser ureterorenoscopy (URS) treatments. The database consists of 80,000+ patients who have undergone kidney stone treatments at multiple sites throughout the United States. The purpose of the database is to provide data to medical researchers so they can determine best practices and trends through analytics and statistical analysis with the long-term goal of improving patient outcomes and experiences.
Example
KSR data were used to develop a computer-assisted Artificial Intelligence (AI) model to predict optimal shockwave applications for effectively fragmenting kidney stones while minimizing treatment complications. Below are three images showing the before and after x-images of a kidney stone and the shift of pixel intensities in a scatterplot that confirms a successful treatment delivery.
Shockwave treated stone
Kidney stone is fragmented into small pieces by lithotripsy shockwave applications.
Scatter plot.
The shift in pixel intensities from the initial stone to the treated stone confirms kidney stone fragmentation.
