The main symptoms of kidney and ureteral stones

The main symptoms of kidney and ureteral stones include: 1. Pain: Patients may experience back or abdominal pain. Particularly smaller stones can cause smooth muscle spasms leading to colicky pain, which is severe and knife-like, often starting suddenly and radiating to the lower abdomen, genital area, and inner thighs. 2. Hematuria: Due to direct injury to the mucous membranes of the kidney and ureter by the stones, about 80% of patients will have hematuria, with some cases presenting gross hematuria visible to the naked eye. 3. Pyuria: When stones are complicated by infection, pus cells may appear in the urine, accompanied by symptoms such as high fever and back pain. 4. Other symptoms: Obstruction caused by stones can lead to hydronephrosis and even renal insufficiency. Some patients may also experience gastrointestinal symptoms or anemia. If these symptoms occur, it is recommended to seek timely medical examination and treatment.
