Which condition might result if renal calculi obstruct the urinary tract?

When renal calculi, commonly known as kidney stones, obstruct the urinary tract, one significant consequence can be acute kidney injury (AKI). This condition occurs when the flow of urine is impeded, leading to a buildup of pressure in the kidneys. When pressure in the renal system rises, it can affect renal function, causing damage to the kidneys. This can lead to a sudden decline in the kidneys' ability to filter waste products from the blood properly.

Acute kidney injury is particularly concerning because it can develop rapidly, sometimes within hours, and can lead to a range of complications if not addressed promptly. Symptoms may include decreased urine output, swelling, and other signs of renal distress. Managing kidney stones to prevent obstruction is crucial in maintaining kidney health and preventing the onset of AKI.
