  The increased reabsorption of sodium chloride results in hyperchloremia with ensuing volume expansion and hypertension. [9] Volume expansion results in secondary hypoaldosteronism and, consequently, in hyporeninemia. [emedicine.medscape.com]

What is the Prognosis of Renal Tubular Dysgenesis? (Outcomes/Resolutions) Renal Tubular Dysgenesis is a severe congenital disorder and the prognosis is often reported to be poor. [dovemed.com]

Long term prognosis varies from one case to another, and cases of both full recovery and fatalistic implications have been recorded. [hxbenefit.com]

An early diagnosis provided by the pathognomonic oral phenotype can lead to a better long-term renal prognosis. [indianjnephrol.org]

Treatment: High doses of bicarbonate are required but the prognosis is good. Correcting acidosis and low potassium levels allows normal growth and prevents bone disease; however, vitamin D supplements may also be required. [patient.info]
