Lipuria

Lipuria (from Latin lipuria, from lipus urine, Latin ura urine) is a type of pseudoamyloidosis, a pathological condition in which abnormally short symmetrical protein molecules called lipofuscins are deposited in the kidneys. The term lipurgia is used by physicians to refer to the urinopathic phenotype. Phenotypic manifestations of lipofuscinaria include abnormal skin pigmentation resulting from the deposition of lipofuscin-containing particles, specific skin tests for altered urine, and a gradual decline in renal function with the gradual development of chronic renal failure (CRF).

**Synonyms:** piesia (piopoeia, Greek)

Lipurgi syndrome The disease has another name - Lipur syndrome; it was proposed back in 1956, when some scientists discovered the characteristic symptoms of Lipur syndrome in a 4-year-old boy. Later it was identified as a separate pathology. The disease is recognized as rare and no corresponding nosology has been found for it. It has individual symptoms that are characteristic throughout Europe. It is clarified that the main cause of the development of Lippurg syndrome is a hereditary predisposition.
