Bartter syndrome (BS) is a rare inherited salt-losing renal tubular disorder characterized by secondary hyperaldosteronism with hypokalemia and hypochloremic metabolic alkalosis, and normal or low blood pressure. In severe cases, preterm delivery, hypovolemia, ventricular arrhythmia, rhabdo-myolysis, renal failure, growth failure and sensorineural deafness may occur. In recent years, research on BS has made significant progress. The Bartter Syndrome Consensus Working Group has performed a systematic literature review, and based on evidence-based medicine, summarized aspects related to BS, including clinical manifestations and classification, diagnosis, treatment strategies, and management of complications. This consensus provides an important reference for the better diagnosis and treatment of BS.
