Residual urine volume in bladder after urination

Many people still feel that there is residual urine in their bladder right after urinating, which makes them feel very uncomfortable and anxious. In fact, this may be due to some inflammatory stimulation inside their bladder, so the best way is to treat it with anti-inflammatory and analgesic drugs. After taking the drugs, the occurrence of this situation can be gradually improved.

Inflammatory stimulation

When there is inflammation in the bladder, the nerve perception threshold is lowered and the urination center is in an excited state, resulting in incomplete urination and reduced urine volume (<300-500 ml/time in adults). Therefore, inability to urinate completely is an important symptom of cystitis, especially in acute cystitis and tuberculous cystitis. Other conditions, such as prostatitis, urethritis, pyelonephritis, chronic balanoposthitis in children, vulvitis, etc., may also cause urinary incontinence. Under the stimulation of inflammation, incomplete urination, urgency and pain in urination often occur at the same time, which is called urinary tract irritation syndrome, commonly known as the "tri-uria syndrome".

Non-inflammatory irritants

For example, urinary tract stones and foreign bodies usually present with incomplete urination as the main manifestation.

Bladder capacity

Such as bladder space-occupying lesions, compression from the enlarged uterus during pregnancy, tuberculous bladder contracture, or large bladder stones.

Neurological

Incomplete urination only occurs during the day or before going to bed at night, and is often caused by mental tension or hysteria. This may also be accompanied by urinary urgency and pain.

Urinary incompleteness refers to the feeling of a full bladder and an urgent need to urinate, which cannot be relieved after urination. It is also accompanied by symptoms of frequent urination, urgent urination, painful urination, and white discharge from the urethra. This condition is called "incomplete urination" in medicine, and quantitative indicators are given to diagnose this disease: urination of 1000-2000ml per day, 4-6 times during the day, and 0-2 times at night. Any flow beyond this range can be confirmed as incomplete urination.

Increased urine output

As urine volume increases, the frequency of urination will also increase accordingly. Under physiological conditions, such as drinking large amounts of water, eating watermelon, and drinking beer, due to the increase in water intake, the urine volume increases through the regulation and filtration 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, they drink a lot of water, urinate a lot, and urinate frequently. But there was no discomfort in urination.
