[Purple urine bag syndrome in two institutionalised patients].

Purple urine bag syndrome (PUBS) is an uncommon but particularly striking phenomenon characterised by a chemical reaction involving the urine, plastic and certain enzymes from some sulphatase- and phosphatase-producing bacteria, including Proteus mirabilis, Escherichia coli and Morganella morganii, amongst others. Following this reaction, the catheter and the bag may be stained red, blue or purple. This phenomenon tends to occur in patients with multiple pathology and with urinary catheters, as part of a urinary tract infection.
