Usually bacteriostatic therapy can be used to treat chronic pyelonephritis, but the efficacy has individual differences.
The antibacterial drugs for chronic pyelonephritis are similar to those for acute pyelonephritis, and the drugs include cefuroxime, ciprofloxacin, etc. The duration of the drugs can be extended to 2-4 weeks, and if it is ineffective or recurrent, the sensitive drugs can be used in 2-4 groups for a total of 2-4 months.
If the above long course of antimicrobial treatment is still ineffective or recurrent, low-dose long-term bacteriostatic treatment can be used, such as sulfa, furotoxin, norfloxacin, etc. One of the 1 dose, taken every night before bedtime after urination, the course of 6 to 12 months, can prevent recurrence.
If there are susceptibility factors, such as urinary tract obstruction, urinary tract deformity, immunocompromise, etc., it is still easy to be re-infected or recur, and the key to the treatment of this kind of situation is to remove the causative factors.
Patients with chronic pyelonephritis are advised to go to the nephrology department of the hospital and receive standardized treatment under the guidance of the doctor, and not to use medication on their own.
