This will be a prospective, randomized, single-blinded controlled trial in which the investigators evaluate post-operative serum glucose control using conventional point-of-care glucose monitoring in the morning and before meals (standard of care) versus continuous glucose monitoring using the Medtronic Guardian™ Sensor 3 continuous glucose monitor. The investigators will compare the average daily glucose level in the post-operative period (through post-operative day five) between the two arms in patients with diabetic nephropathy immediately post-renal transplant. This will serve as a pilot study to in order to power a main study.
