Long-term management of inherited renal tubular disorders.

In inherited renal tubular disorders with isolated defects of tubular transport medical treatment is usually either not indicated or is simple and effective. In some inherited metabolic disorders with complex defects of renal tubular transport a specific therapy is known. For example, in galactosemia and hereditary fructose intolerance crude products may be restricted or in cases of Wilson's disease copper stores may be reduced. In idiopathic Fanconi syndrome, cystinosis, oculocerebrorenal syndrome and glycogenosis Fanconi-Bickel, a symptomatic replacement treatment based on supplementation of water, electrolytes and vitamin D has improved the non-uremic survival of these patients considerably within the last 20 years. For long-term management of inherited renal tubular disorders, treatment of tubular dysfunction, chronic renal failure, and involved extrarenal organs must be supported by genetic counseling and assistance for social integration.
