Hypercalcemia of malignancy is a common finding associated with different types of cancers; however, its association with urothelial carcinoma of the bladder is rare. We report a case of a 69-year-old male with nonmetastatic urothelial carcinoma of the bladder who developed hypercalcemia that failed to respond to medical management, but resolved completely after undergoing resection of the tumor through radical cystectomy.
