Doctor's answer:

Considering it may be a urinary tract infection, urinary tract infections are caused by bacteria (in very few cases, fungi, protozoa, or viruses) directly invading the urinary system. It is important to maintain good hygiene of the external genitalia. Urinary tract infections often have certain triggers, so it is necessary to carefully examine the patient for conditions such as urinary tract stones, kidney or ureteral abnormalities, etc. In addition to medication, drinking plenty of water and maintaining a daily urine output of over 2000ml can help flush the urinary tract, which is also very important for the treatment of urinary tract infections.
Additionally, gonococcal urethritis is also very common at present. If present, it should be treated as gonorrhea first. A significant amount of clinical experience has been accumulated in the use of traditional Chinese medicine for treating urinary tract infections. Medications such as Banlangen ( ), Diding ( ), Baigancao ( ), and Cheqiancao ( ), which have detoxifying and heat-clearing properties, can be used. Furthermore, it is also important to pay attention to strengthening nutrition and enhancing physical fitness.
