Why can't boys urinate completely?

Urinary system diseases are becoming more and more common in modern life, causing great harm to people's bodies, because the urinary system must always collect waste fluids such as urine produced in the body and excrete them out of the body through the urethra. However, problems with the urinary system will cause great obstacles to its excretion ability, causing physical abnormalities, etc. For example, male urinary incontinence is a common hazard. Let's take a look at why boys cannot urinate completely?

Urinary incontinence refers to the feeling of bladder distension, urgent urination, and inability to relieve distension after urination, accompanied by frequent urination, urgent urination, urinary pain, and white discharge from the urethra. Medicine calls this condition "urinary incontinence" and provides quantitative indicators for diagnosis: 1000-2000ml of urination per day, 4-6 times during the day, and 0-2 times at night. Anything beyond this range can be confirmed as urinary incontinence.

When the urine volume increases, the frequency of urination will also increase accordingly. Under physiological conditions, such as drinking a lot of water, eating watermelon, and drinking beer, due to the increase in water intake, the urine volume increases through the regulation and filtering function of the kidneys, and the frequency of urination also increases, resulting in incomplete urination. Under pathological conditions, such as some patients with diabetes and diabetes insipidus who drink a lot of water, have a lot of urine, and urinate frequently. However, they do not feel any discomfort when urinating.

Causes

Inflammatory irritation

When there is inflammation in the bladder, the nerve receptor threshold is lowered, the urinary center is in an excited state, resulting in incomplete urination and reduced urine volume (<300-500 ml/time for adults). Therefore, incomplete urination is an important symptom of cystitis, especially acute cystitis and tuberculous cystitis. Other diseases such as prostatitis, urethritis, pyelonephritis, chronic penile capitis in children, and vulvitis can also cause incomplete urination. Under the stimulation of inflammation, incomplete urination, urgency, and pain when urinating often occur at the same time, which is called urinary tract irritation sign, commonly known as "tri-urination sign".

Non-inflammatory irritation

Such as urinary tract stones and foreign bodies, usually with urinary incontinence as the main manifestation.

Reduced bladder capacity

Such as bladder space-occupying lesions, pressure from an enlarged uterus during pregnancy, tuberculous bladder contractions, or larger bladder stones.

Neurological

Incomplete urination occurs only during the day or before going to sleep at night, often due to nervousness or hysteria. It may also be accompanied by urinary urgency and pain.
