[Lymphatic malformation and chyluria: presentation of a treated case without relapse]

Chyluria is a consequence of the aperture of one or more perirenal lymphatic vessels to the renal pelvis, and is characterized by milky urine, rich in protein, lipids, cholesterol and triglycerides. Where there is chyluria there is malformation of the chyliferous vessels of the small intestine associated to hypoplasia of Pecquet's cistern. A 22 year old patient who had had persistent chyluria since the age of 16 is presented with a test of induced hyperlipidemia typical of intestinal lymphatic malformation. Chyluria was demonstrated by lymphography by bilateral pedial approach and ascending pyelography. Following surgical ligation of the lymphatic vessels of the left kidney the chyluria remitted and the patient has had no further clinical manifestation up to the present, one year after surgery.
