Can hydronephrosis disappear by itself after stone discharge?

The symptoms of hydronephrosis may

disappear automatically after stone discharge

. However, if the stone obstruction lasts for a long time, the structure of the renal collecting system has undergone organic changes, and renal function is impaired, stone discharge can only relieve symptoms, and hydronephrosis generally cannot completely disappear.

If the patient's condition is severe, renal parenchyma is significantly damaged or atrophied, nephrectomy may be performed if necessary.
