The clinical consideration for weak urination is bladder outlet obstruction and weak bladder contraction. 1. Bladder outlet obstruction: this situation is common in men with prostate hyperplasia, the prostate hyperplasia tissue will cause pressure on the urethra or make it narrow, resulting in men with symptoms of weakness of defecation, accompanied by frequent urination, urinary urgency, urinary incontinence, etc., and can also have a negative impact on sexual function. 2. Weak bladder contraction: some people frequently exert themselves to urinate, which will cause the bladder muscle to lose compensation, thus showing weakness when urinating; some people have had pelvic surgery, spinal cord lesions or peripheral neuritis, etc., which will damage the nerves innervating the bladder and lead to bladder contraction, which will cause the corresponding symptoms. If the symptoms persist, it is recommended to go to the urology department of the hospital for appropriate treatment.
