What to expect

Useful information

Patients seeking urology services are usually first evaluated by our internal medicine service. After an initial evaluation, urology is consulted as to the best next steps.

 At the heart of the urology service is the Minnesota Urolith Center. This center is the largest stone analysis laboratory in the world (animal or human), analyzing over 80,000 submissions worldwide. Visit us at urolithcenter.org for more information on preventing stone recurrence.

For clients seeking stone removal by laser lithotripsy, the urology service offers free consultation for your referring veterinarian to determine if your dog or cat is a good candidate for nonsurgical stone removal prior to the appointment.

For clients interested in learning about research on genetic risk factors for stones, please visit the Canine Genetics Laboratory website at z.umn.edu/caninegenetics or e-mail [email protected].

X-rays can be electronically mailed to [email protected]; please include the nature of the request, the weight of the patient and diameter of the largest stone.
