Urolith prediction is a two-step process. The first step is a prevalence calculation performed in the App. The second step requires your clinical judgement by comparing your patient’s radiograph with radiographic images provided in the app.
Step 1: Use the drop-down menus to input your patient’s species, breed, gender, and age. Then activate the search button. Your selection will run through our large database of cases at the Minnesota Urolith Center to reveal how often each stone type occurred in patients with similar identity
Step 2: Select the radiographic image on the App that matches the radiographic appearance of your patient’s stone. It may not be the one with the highest prevalence in the app but is usually close.
The radiographic appearance of this cat’s stone matches the image with the highest prevalence in CALCUlate. This cat’s stones are likely composed of calcium oxalate.
In dogs, use CALCurad, our other App tool, to differentiate between dissolvable struvite stones and other stone types.
If a radiographic image is not available for your patient, select the stone type with the highest revalence.
Step 3: Read about the urolith type(s) that match your patient’s signalment and radiographic stone appearance to guide diagnosis, treatment, and prevention.
