What causes polyuria during the stage of renal insufficiency?

Question

Quizplus · Accepted Answer

Polyuria during renal insufficiency is often caused by a loss of tubule function, which can lead to a decreased ability to reabsorb water and concentrate urine. This results in a larger volume of urine being produced and excreted. Increased blood pressure or decreased aldosterone secretion may impact renal function but are not directly associated with polyuria. While increased GFR may contribute to polyuria in some cases, it is not the primary cause of polyuria in renal insufficiency.
