Renal lesions in sickle cell nephropathy in children.

abstract：BACKGROUND/AIMS:Tolvaptan, a vasopressin V2 receptor antagonist, promotes the excretion of electrolyte-free water. Patients with heart failure or liver cirrhosis, whose urine osmolarity is high due to increased vasopressin, show a good response to tolvaptan; however, it remains dubious whether tolvaptan is also effecti...
