Gender and Race Disparities Found in Kidney Stone Disease

Kidney stone disease is characterized by racial and sex disparities, according to data presented during the AUA2021 Virtual Experience.

Joseph Crivelli, MD, of the University of Alabama at Birmingham School of Medicine and colleagues identified patients with a kidney stone diagnosis from 2010 to 2019 using 5 large datasets: 30,966 patients from the University of Alabama at Birmingham (UAB); 45,604 patients from the University of Texas Southwestern (UTSW); 21,796 from Parkland Memorial Hospital (PMH); 42,652 from Henry Ford Health System; and 16,618 from UC Davis Health System. For temporal trends, the investigators analyzed claims data from 68,594 patients in Optum Clinformatics Data Mart.

Most Black stone formers were female, whereas most White and non-Hispanic stone formers were male, the investigators reported in a poster presentation. In 2 of the 4 cohorts, the majority of Hispanic stone formers were female. The male-to-female ratio differed significantly between Black and White stone formers, and to a lesser degree between Hispanic and non-Hispanic stone formers. The study did not assess male-to-female ratio among Asian, Hawaiian/Pacific Islander, and American Indian/Alaska Native stone formers.
