CHICAGO—Annual incidence of renal or ureteral calculi is increasing in the United States and may have bearing on management, research findings presented at the 2019 American Urological Association annual meeting suggest.

“It is well established that the prevalence of nephrolithiasis is increasing in American adults over time,” investigator Gina Tundo, MD, of Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, told Renal & Urology News. “Cross-sectional studies suggest that 11% of men and 7% of women will experience nephrolithiasis in their lifetime. Less is known, however, about annual incidence rates. We feel our data, which reports on the latter parameter, better describes the burden of acute management and may help to better direct resource allocation.”

According to their nationally-representative analysis of US adults from the Medical Expenditure Panel Survey, annual stone occurrence rose significantly from 0.6% in 2005 to 0.9% in 2015. In 2005, the mean age of stone formers was 45 years, 52.2% were male, 92% were white, and 47.6% resided in the South. In 2015, stone formers were slightly older (mean 51.7 years) and fewer were white (83%) and resided in the South (38.2%). Approximately 10% of stone formers had college degrees in 2005 compared with 20% in 2015.
