One of the most lethal consequences of mismatched blood transfusions is acute kidney failure caused by blockage of urine-forming structures by haemoglobin precipitation.

Question

Quizplus · Accepted Answer

Hemoglobin precipitation in the kidneys can cause acute kidney failure by blocking urine-forming structures. This occurs when incompatible blood is transfused, leading to the destruction of red blood cells and the release of hemoglobin into the bloodstream. Hemoglobin can then collect in the kidneys, causing damage to the renal tubules and obstructing urine flow. This can lead to acute kidney failure, which can be a life-threatening complication.
