UTI patients are reviewed after treatment to know if the UTI is healed and the pathogens are cleared. UTI patients are usually advised to continue using the medication for 7-10 days after their symptoms have subsided, and then stop taking the medication for a week and then go for a routine urine test to see if there are still pathogens or white blood cells in the urine. If the urine routine has completely returned to normal, the UTI is considered cured. If the patient does not have a full course of anti-infection treatment, even if the symptoms disappear, there will still be pathogens in the urine and urethral mucosa, which can easily lead to the recurrence of urinary tract infections, and even cause the infection to persist, resulting in chronic urethritis, and irregular use of anti-infection drugs, but also easy for the pathogens to develop resistance, resulting in the treatment of urethritis is more difficult.
