What causes weak urine?

The bladder may contract to increase urination. As the disease progresses, the patient's urethra may become narrower, increasing the contractile pressure of the bladder, and the bladder will gradually become contractile, so the patient's urine range will become shorter when urinating. If the disease continues to develop, the patient will also show frequent urination, urgency, urine not enough symptoms, as well as show urine line thinning, urine line intermittent, and even show urine dripping, the disease development caused by complete urethral stricture, but also show the phenomenon of urination.
