There are two possibilities: 1. The patient has acute urinary retention, and although he has a strong urge to urinate, he cannot urinate, so he needs to check the urinary ultrasound plus residual urine. If there is a large amount of residual urine in the bladder, the patient can be induced to urinate by means of hot compresses or local massage or running water sound induction. if the appeal method is not effective, the patient can be treated by indwelling catheter catheterization. 2. because the patient has urinary tract infection, in this case there is no large amount of urine in the urinary tract ultrasound, the patient can be relieved by taking oral anti-inflammatory drugs and asking the patient to drink more water to make the symptoms.
