[Purple urine bag syndrome (PUBS): about two cases at the Regional University Hospital Center (CHUR) of Ouahigouya].

Purple urine bag syndrome (PUBS) is an uncommon complication of urinary tract infection. It mainly affects elderly patients with constipation, chronic urinary catheter and prolonged bed rest. Several bacteria belonging to two different groups, the group converting indoxyl urinary sulphate into indoxyl and the group alkalizing urine by the production of urease, are associated with it. We here report two cases of young patients aged 30 and 16 years, living in Burkina Faso, with uremic encephalopathy associated with severe infection and cloudy urine with purple urine bag. Unlike cases reported in the literature, our cases occurred two and four days after urinary catheterization and in young patients without constipation. Despite early antibiotic therapy, outcome was unfavorable in one patient.
