Stone Rates Drop by 80% in Dr. Coe and Dr. Asplin's Clinic


The leading North American study of the cost benefit of testing and treating kidney stone formers features the University of Chicago Kidney Stone Clinic headed by Litholink founders Coe and Asplin.  The study, published in Kidney International in 1996, was based on 1,092 stone formers treated at the clinic and included all the patients for whom records were kept.

Below is a graph showing the change in stone rates before and after treatment.  Treatment caused an 83% reduction in the rate of stone formation.

The study estimated the savings in this population are in the range of $2,158 per patient in the first year, net of treatment and pharmacy costs.
