Résumé
La coloration violette d’une poche à urines sans modification de couleur des urines, chez un patient porteur d’une sonde à demeure, est connue sous le nom de « syndrome de la poche à urines violette » (purple urine bag syndrome en anglais). Nous rapportons le cas d’une patiente tétraplégique en sonde urinaire à demeure, qui a présenté un tel syndrome. Ce syndrome est lié à une succession de dégradations enzymatiques à partir d’un acide aminé, le tryptophane, et à la présence de certaines bactéries dans les urines. Il survient préférentiellement chez la femme âgée ayant peu de mobilité ; il est bénin et rare et ne justifie pas une antibiothérapie systématique. Il mérite cependant d’être connu.
Abstract
The purple color of a urine bag without modification of the color of the urine, from a patient with a urinary catheter drainage system, is known as Purple Urine Bag Syndrome. It is related to a succession of enzymatic degradations of an aminoacid called tryptophan and to the presence of certain bacteria in the urine. It occurs predominantly in elderly, disabled women. We report the case of a tetraplegic woman, chronically catheterized because of a neurologic bladder disorder. This syndrome is benign and rare. It does not justify systematic antibiotherapy but deserves to be known.
