A man wants to pee but can't

The human body is a complex structure that needs to eat and excrete waste. Urination is a process of removing waste. In real life, many male compatriots will encounter some symptoms that they want to urinate but cannot urinate. When this happens, they will often doubt their bodies and suspect that there is something wrong with them. But what are the real reasons why men want to urinate but cannot urinate? What is the root cause of this situation?

The physiological process of urination: When the bladder is full of urine, the brain will send out a urination signal, which causes the detrusor muscle to contract and the urethral dilator muscle to relax through nerve regulation, and then urine enters the urethra. The waiting time from the brain sending out the urination signal to the actual urination is too long, and this symptom is called urine waiting. From the analysis of the physiological process, the problem of urine waiting is mostly caused by nerve conduction, detrusor muscle, urethral dilator muscle, etc.

What are the specific reasons why men want to urinate but cannot?

Psychological factors: When going to the toilet or being hospitalized, some people may feel panic and nervous when urinating. In this state, the dilator muscle in the urethra will be tense and not relax, and it will be difficult to urinate even if the detrusor muscle contracts.

Prostate problems: Dysuria is a common symptom of prostate problems. The prostate participates in the formation of the dilator muscle in the urethra and has the function of controlling urination. For example, prostate hyperplasia may compress the urethra or bladder neck, causing urinary tract obstruction, leading to thickening of the detrusor muscle, and symptoms such as urinary retention, hematuria, and incontinence. Most prostate cancers are accompanied by obstructive symptoms, including urinary retention, urinary pain, hematuria, or urinary incontinence. Prostatitis may also cause local congestion and swelling, compress the urethra, and cause urinary retention.

Urethral problems: In addition to prostate problems that can affect the urethra and cause urinary retention, urethral problems such as urethral stones, urethritis, urethral injury, urethral stenosis, urethral orifice stenosis, etc. can also cause urinary retention symptoms.

Spinal cord injury: Damage to or disease of the spinal cord below the urinary center may cause urinary incontinence of a neurological nature.

Other reasons: Some drugs have an inhibitory effect on the parasympathetic nervous system, such as antidepressants and certain cold medicines, which can cause urinary retention; excessive drinking may lead to detrusor muscle weakness and prostate edema, leading to urinary retention.

There are many reasons for the occurrence of urinary retention symptoms. When men have urinary retention symptoms, they need to pay attention to whether it is a prostate problem. When there is a prostate problem, there are usually symptoms such as frequent urination, urgency, and pain during urination.

If the symptom of urine retention occurs occasionally, we need to rule out psychological factors or taking certain drugs; if the symptom of urine retention occurs frequently, we need to consider whether it is caused by disease and seek medical examination in time. If the symptom of urine retention is caused by disease factors, eat less spicy and irritating food, eat less salty and flatulent food, and do not drink alcohol; avoid overwork and cold in life.
