Unfavorable urination (dysuria) refers to poor urination, and the possible causes are: urethral obstruction, urinary tract tuberculosis, male prostate hyperplasia, and neurological lesions. 1. Urethral obstruction: mainly for the urethral lumen is not smooth, the urethral muscle contraction dysfunction abnormality. Such as urinary tract stones, tumors, children’s sphincter development is not sound, traumatic ureteral stenosis and so on. 2. Urinary tuberculosis: renal tuberculosis spreads and spreads to the ureter and bladder, causing bladder contracture, fibrosis, the wall of the tube loses its ability to stretch and contract, and the opening of the ureter and bladder closes incompletely, causing urine reflux, which can cause urinary incontinence. 3. Male prostatic hyperplasia: prostatic migratory zone hyperplasia, the formation of multiple nodules caused by urethral obstruction, long-term can be induced by forced urethral muscle dysfunction, manifested as slow urination, terminal dribbling, and often have a sense of incomplete urination. 4. Neurological lesions: including central and peripheral nerve injuries, such as cerebral hemorrhage, spinal cord injury, etc., causing bladder nerve dysfunction, the emergence of incomplete urination. Unfavorable urination has more reasons, it is recommended that the patient timely hospital consultation, improve the examination and standardized treatment.
