Recurrent urinary tract infections after intercourse are more common in clinical practice and are mainly seen in female patients. It is mainly because the urethra of female patients is shorter and straighter, adjacent to the anus and vagina. The treatment of recurrent urinary tract infections should be given to both men and women. First, you should drink more water and urinate more before and after intercourse, so that urine flushes the urethra, which can reduce urinary tract infections. Secondly, strengthen the cleaning and hygiene. Female cleaning should be done from front to back, and men should thoroughly clean the foreskin as well as the coronal groove. If the foreskin is too long or circumcised, circumcision should be done. If there are recurrent urinary tract infections, you can take furatantin before intercourse if necessary to prevent infection.
