Patient: I am a female and every time I have intercourse with my husband, I get painful urination and frequent urination. I was examined for a urinary tract infection, and after taking three gold tablets for a few days, I got better, but the next time we have intercourse, it comes back again. Reply: 1. reduce the frequency of intercourse; 2. drink more water before intercourse and urinate quickly after intercourse; 3. check for vaginitis. Patient: I’ve been checked for vaginal inflammation, but I’ve been having recurrences once a month, and I’m thinking of having children. Reply: Other medications are mainly antibiotics, but Sanjin tablets are effective for mild urinary tract infections. However, your recurrent urinary tract infections are related to your intercourse habits or the proximity of your urethra to your vagina, most commonly due to the introduction of vaginal or perianal bacteria into the urethra. If you can try to avoid this during intercourse and combine it with urination afterwards, you should be able to avoid urinary infections.
