Mainly to prevent urine reflux and control infection, to prevent further damage to renal function. 1. Medical treatment takes different treatment measures according to different grades of VUR. (1) I and II degrees? Treatment of infection and prevention of long-term medication. SMZCo (compound sulfamethoxazole dispersible tablets) can be taken immediately before going to bed for more than one year. In order to effectively prevent infection, urine culture should be done every three months, radionuclide examination or micturition cystography should be done once a year to observe the degree of reflux, and venography should be done once every two years to observe the formation of renal scar. After the reflux disappears, urine culture should still be done every 3 ~ 6 months, because reflux can sometimes be intermittent. In addition, drinking water and urinating twice before going to bed should be encouraged to reduce the internal pressure of bladder, and the stool should be regular and regular. ② Ⅲ degrees? The treatment is the same as I and II degrees, but the reflux is checked every 6 months and intravenous pyelography is done once a year. (3) Ⅳ and Ⅴ degrees? Surgical correction should be performed after preventive medication. 2. Surgical treatment of VUR is mostly plastic surgery. The surgical indication is: (1) Reflux above ⅳ degree. (2) If the degree is below Grade III, medical observation and treatment should be carried out first. If there is persistent reflux and new scar formation, surgery should be carried out. (3) Recurrent urinary tract infection, with no improvement in reflux after active treatment for 6 months. (4) Patients with urinary tract obstruction. At present, injection therapy is popular abroad. This method is only a short-term anesthesia, which requires short-term hospitalization or not and is easily accepted by patients.
