The number of days of hospitalization for kidney stones is related to the patient’s condition. If the patient has a single kidney stone and there is no obvious back pain or hematuria after stone fragmentation, he can go home immediately and does not need to be hospitalized. If the patient has significant pain after lithotripsy and a large number of white blood cells are seen in the urine routine, it is recommended to see a hospital for antibiotic treatment. The stone can be discharged by itself in 5-7 days after lithotripsy, so hospitalization is required for about 7-10 days for ureteral dilatation and anti-inflammatory drugs. The most commonly used drugs are penicillin and cephalosporins, and the drugs for ureteral dilatation are progesterone and magnesium sulfate. If the patient has significant pain, pain medications such as 654-2, morphine, dulcolax and other drugs can be applied. The most serious complication after kidney stone is the formation of stone street, which affects the kidney function. Therefore, it is necessary to review the ion kidney function regularly, and after the stone is eliminated, it is recommended to review the urological ultrasound again to clarify the stone discharge.
