Green urine after surgical treatment of pressure ulcer

Abstract

We describe a 58-year-old man who developed green urine after operation on a pressure ulcer. The discolouration disappeared gradually after two days. We think that the use of methylene blue dye during the revision of the wounds and the use of the sedative propofol could have caused it.
