Ureteral calculi are common in urology. Pain and hematuria are the main symptoms of ureteral calculi. Pain can be dull pain, dull pain, distention pain, colic, etc. Most of them are located in the lumbar rib or lower abdomen. Hematuria can be microscopic or macroscopic. Ureteral calculi can cause urinary tract obstruction, leading to hydronephrosis. The heavier the hydronephrosis, the worse the renal function. Clinically, the treatment plan is generally selected according to the size and location of stones and the degree of hydronephrosis. Urinary calculi are caused by some factors, such as high concentration or low solubility of lithogenic substances in urine, which gradually form calculi. Their incidence is related to race, heredity, environment, diet, metabolism and urinary diseases.
