In this analysis of 306 hospital referral regions, regional CT risk was significantly correlated with nephrectomy, and scanning an additional 1000 Medicare beneficiaries was associated with 4 additional nephrectomies. Beneficiaries residing in high-scanning regions face a higher risk of nephrectomy, presumably reflecting the incidental detection of kidney masses. Fee-for-service Medicare beneficiaries are commonly exposed to CT imaging. Those residing in high-scanning regions face a higher risk of nephrectomy, presumably reflecting the incidental detection of renal masses. Additional surgery should be considered one of the risks of excessive CT imaging.
