Prevalence of Stone Disease and Procedure Trends in the United States.

To evaluate the prevalence of stone disease and procedure trends among US commercial and Medicare populations.

Retrospective analyses for a US commercial population and Medicare population were conducted using the Merativeā„¢ MarketScan Commercial Database and Medicare Standard Analytic File (5% sample), respectively.

Patients aged 18+ were included if they had an encounter in any setting with a primary stone diagnosis or stone procedure (ureteroscopy, percutaneous nephrolithotomy, or shockwave lithotripsy) between 2011 and 2019. Analyses were conducted at the patient level.

Over the study time horizon, the prevalence of stone disease showed a small yet statistically significant decrease in the commercial population (1.04% to 1.01%; p<0.0001) and a statistically significant increase in the Medicare population (1.84% to 2.34%; p<0.0001). Ureteroscopy (URS) procedure volumes increased by 22.6% (p<0.0001) in the commercial population and by 56.6% (p<0.0001) in the Medicare population over the study period. Similarly, percutaneous nephrolithotomy (PCNL) procedure volumes increased by 17.4% (p<0.0001) in the commercial population and 27.5% (p<0.0001) in the Medicare population. Procedure volumes for shockwave lithotripsy (SWL) decreased by 26.9% in the commercial population (p<0.0001) and by 3.8% in the Medicare population although the results were not statistically significant.

The prevalence of stone disease showed a small decrease in the US commercial population and an increase in the Medicare population over the study time horizon. In both populations, increasing procedure volumes were observed for URS and PCNL while decreasing volumes were observed for SWL.
