Urinary tract infection is a common disease in the elderly population, second only to respiratory tract infection in infectious diseases in the elderly, the main reason why the elderly are prone to urinary tract infection is because of the decline in systemic and local immune defense function, while the elderly kidney and bladder mucosa are in a relative ischemic state, pelvic muscle relaxation, habitual constipation, etc. can further aggravate the poor blood circulation in the local mucosa; secondly, postmenopausal women In addition, postmenopausal women have decreased ovarian function, decreased estrogen secretion, degenerative changes in the urethral mucosa and decreased antacid secretions, and increased sensitivity of the urethral epithelium to bacterial adhesion; in addition, the elderly often have urethral obstruction and poor urinary drainage due to prostate enlargement or bladder neck obstruction, as well as urinary stones and tumors, and the local antibacterial power of the urethral epithelium is reduced, thus making it easy for urinary tract infections to occur. The actual fact is that you will be able to get a lot more than just a few of the most effective and most effective products. In fact, there are some misconceptions here. It is generally believed that a single course of antibiotic therapy should be given to any patient who is first found to have bacteriuria, regardless of the presence or absence of symptoms. Because of the extremely high recurrence and reinfection rates in the elderly, long-term maintenance application of antibiotics for asymptomatic bacteriuria is unnecessary and does not lead to a reduction in recurrence and morbidity and mortality rates. In fact treatment of urinary tract infections in the elderly should begin with attention to treating underlying conditions such as diabetes and hypertension, getting rid of obstructive factors including prostate enlargement, urinary stones and tumors, and encouraging patients to drink more water. Why should antibiotics be used with caution? First of all, the glomerular filtration rate of the elderly itself decreases year by year, the drug metabolism is slow, easy to cause antibiotics hepatic and renal toxicity; secondly, repeated use can cause bacterial resistance, destroy the normal flora of the body, the natural flora of the vagina is removed along with the pathogenic bacteria, weakening the body’s own defense mechanism. In addition, the effective bactericidal concentration of drugs in the bladder and urethra is not enough, often resulting in poor efficacy. Chinese medicine has certain advantages in the treatment of urinary tract infections in the elderly, which is considered to belong to the category of gonorrhea in Chinese medicine. As early as the Sui dynasty, the “Treatise on the Origin of Diseases? The “gonorrhea” points out: “all gonorrhea, by the kidney deficiency and bladder heat also …… kidney deficiency is urine number, bladder heat is underwater astringent, number and astringent, then gonorrhea does not declare, so it is called gonorrhea.” The Jin dynasty medical doctor Liu Heshe summarized the pathogenesis of this disease as “kidney deficiency, bladder heat”. The ancients have realized that urinary tract infection is not entirely caused by the real evil, “kidney deficiency” is an important factor in the development. The deficiency of the kidney in the elderly is becoming more and more obvious, the kidney energy is weakened, the sky is exhausted, the essence and blood is insufficient, the yin orifice is not moistened and is vulnerable to the attack of damp-heat disease; damp-heat injection, the bladder is not conducive to gasification, the watercourse is not open to the urine is frequent and urgent, dripping and astringent pain. Therefore, urinary tract infection is a deficiency evidence, with kidney deficiency as the main cause. The two main principles in the treatment of urinary tract infections are to clear heat and dampness, detoxify and clear the lung and tonify the kidney. Due to the decline in the function of the internal organs of the elderly, especially the deficiency of kidney qi, in the treatment should pay attention to the regulation of the overall functional status, with local treatment to promote laxative and dampness, in order to take into account both the symptoms and the root cause, to achieve better results. Since most of the urinary tract infections in the elderly are complicated urinary tract infections, attention should be paid to finding susceptible factors of urinary tract infections, such as urinary tract obstruction, malformation and vesicoureteral reflux due to stones, strictures, tumors, prostatic hyperplasia and other diseases, or chronic infections, such as pelvic inflammatory disease, cervicitis, paraurethritis, prostatitis, or systemic chronic diseases, such as diabetes, severe The most important thing is to treat the infection with Chinese medicine. In the treatment of urinary tract infection with Chinese medicine, it takes one to three months for most urinary bacteria to turn negative. Therefore, when treating this disease, we should pay attention to keep the prescription, do not change the prescription frequently, generally keep the prescription for 4 weeks is appropriate, for those who have seen the effect, do not suddenly stop the medicine, need to continue treatment for 3 to 6 months, so that the disease is not easy to relapse after the urinary bacteria turn negative. In addition, you should drink more water to promote urination (about once every 2 to 3 hours), so that the daily urine volume is maintained at more than 1500mL to promote the early excretion of bacteria and inflammatory exudates and reduce the reproduction of bacteria in the urinary tract. Active physical exercise to enhance functional immunity and improve resistance to disease.
