Symptoms of hydronephrosis occur due to swelling of the kidney caused by the accumulation of urine in this organ as a result of a blockage of urinary flow. Symptoms characteristic of hydronephrosis include:
Chronic hydronephrosis, a progressive, slow-moving disease, may not cause symptoms or cause only episodes of pain on the affected kidney side.
- Treatment of hydronephrosis may be done with medicines to reduce kidney inflammation or in some cases surgery to resolve the cause of ureter obstruction that prevents proper passage of urine.
