A man in his 80s with a history of mild dementia and peripheral vascular disease with left below the knee amputation presented to our general medicine service with several weeks of fatigue and worsening lower extremity edema. He was found to have acute kidney injury and nephrotic range proteinuria. He did not have his prosthesis in the hospital and was unable to ambulate to the bathroom without it. A urinary catheter was placed to monitor urinary output while he received diuretics. After several days of diuresis, his symptoms were much improved, and he was discharged home.
