Are ureteral stones with hydronephrosis and infection serious?

Ureteral stones accompanied by hydronephrosis and infection represent a relatively serious condition. The stones obstruct the ureter, preventing normal urine drainage and leading to the accumulation of urine (hydronephrosis). Prolonged obstruction may further cause infection and damage to the urinary system. The infection can progress and spread inflammation to surrounding areas, potentially leading to severe complications such as renal failure. Additionally, without timely treatment, normal urination function may be affected, resulting in symptoms such as urinary retention and anemia. Therefore, patients with ureteral stones accompanied by hydronephrosis and infection should seek prompt medical attention and receive targeted treatment to prevent disease progression.
