<unk>  refers to the excretion of urine whose specific gravity (concentration) is neither greater (more concentrated) nor less (more diluted) than that of protein-free plasma, typically 1.008-1.012.<unk>  reflects damage to the kidney's tubules or the renal medulla. A closely related term is hyposthenuria, where the urine has a relatively low specific gravity "due to inability of the kidney to concentrate the urine normally". This specific gravity is not necessarily equal to that of plasma. Therefore, unlike<unk> , this condition is not associated with kidney failure as the kidney tubules have altered the glomerular filtrate.
