1, the treatment of urinary tract infections in the elderly should be particularly cautious, especially the use of nephrotoxic drugs, the dose, method and course of treatment should be appropriate to prevent damage to the kidneys. The use of aminoglycosides, such as gentamicin and kanamycin, is prohibited. 2, the treatment of the urinary tract of the elderly should first pay attention to the treatment of underlying diseases, remove obstructive factors, and encourage patients to drink more water. 3, for elderly women with urethritis can try to use a small amount of local estrogen, may be beneficial to restore the physiological state of the lower urinary tract. 4, At present, it is generally believed that, regardless of the presence of symptoms, all patients who are first found to have bacteriuria should be given a single course of antibiotic treatment. It is possible to select drugs according to the bacteria and drug sensitivity of the urine culture to actively control the infection. 5, because the recurrence and reinfection rates of urinary tract infections in the elderly are extremely high, the long-term maintenance application of antibiotics for asymptomatic bacteriuria is unnecessary and does not reduce the recurrence rate or morbidity and mortality rate. More aggressive treatment of elderly patients with urinary tract infections should only be given when early bladder infection, with progressive renal impairment and the presence of upper urinary tract infection symptoms are present. The medication should always be adjusted according to urine culture and drug sensitivity tests during treatment, and the presence of drug-resistant strains or special pathogens should be noted in elderly patients with difficult-to-cure urinary tract infections.
