A unique case of purple urine: A case report and literature review.

We present a case of purple urine in a patient who received methylene blue and hydroxocobalamin for catecholamine-refractory vasodilatory shock. The patient's purple urinary discoloration is presumed to have resulted from a combination of the blue and red pigments of methylene blue and hydroxocobalamin, respectively. As these drugs are increasingly being used to treat vasoplegia in cardiopulmonary bypass, it is important for clinicians to be aware of this benign cause of urine discoloration.
