If the urine volume is low and the number of times is high, further examination is needed to clarify the cause and then decide how to treat it.1. If the urine volume is low and the number of times is high without other accompanying symptoms, such as painful urination, urgency, lumbago, fever, abdominal pain, and a sense of incomplete urination, functional disorders such as overactive bladder and psychogenic urinary frequency are considered. Urological ultrasound and urodynamics are recommended. If overactive bladder muscle is present and infection is excluded, take tolterodine tartrate 2mg orally twice daily or solifenacin succinate 5mg orally once daily for 10 days and observe if the symptoms improve. 2. If there is painful urination, abdominal pain and lumbago, consider possible infection. It is recommended to perform routine urine examination and culture examination. If the infection is clear, it is recommended to take levofloxacin hydrochloride capsule orally, 1 capsule, 3 times daily, or cefixime capsule, 1 capsule, 2 times daily, for 1 week, and observe whether the symptoms improve.
