Clindamycin is generally not used in the preferred treatment of urinary tract infections. Its antibacterial spectrum mainly targets anaerobic bacteria and Staphylococcus epidermidis, etc. It can be applied to treat epidermal, joint, abdominal and gynecological infections, but its concentration in urine is relatively low, so it is not preferred for urinary tract infection. Clindamycin is not used as a routine drug to treat urinary tract infections unless the patient has a urine culture and drug sensitivity test and is more sensitive to clindamycin. The most common drugs used to treat urinary tract infections are still fluoroquinolone antibiotics and cephalosporin antibiotics, which can quickly kill the pathogenic bacteria present in the urinary tract and achieve rapid improvement of the patient’s symptoms. However, in principle, they all require routine urine, urine culture plus drug sensitivity test examination to select the most sensitive antibiotics for targeted treatment, so as to avoid the occurrence of drug resistance and lead to ineffective treatment, but instead, the patient’s condition is delayed for too long.
