Recurrent Polyuria
A 64-year-old man with a history of aplastic anemia underwent haploidentical stem cell transplantation, complicated by graft-versus-host disease affecting his gastrointestinal tract. The posttransplantation course was complicated by bacteremia caused by Klebsiella species and subsequently fungal sinusitis, requiring sphenoidectomy and an extended course of antifungal therapy. One month later, nephrology was consulted for polyuria. The patient denied headache, confusion, changes in vision, weakness, or difficulty ambulating.
