Isosthenuria

Isosthenuria (from Greek ίσος "equal" and σθένος "strength", German also Harnstarre ) referred to in Nephrology the loss of any concentration or dilution ability of the kidney in the context of chronic renal failure. As a result, the original filtrate remains unchanged at a fixed density of 1.010 g / ml. This value corresponds to that of protein-free plasma. This value remains the same regardless of the amount of liquid supplied from the outside.

Regardless of renal failure may also occur as part of a sickle cell anemia isosthenuria.
