What are the symptoms of frequent urination? Characteristics of frequent urination

There are many causes of frequent urination, of which inflammatory and non-inflammatory are the most common. Experts say that the symptoms of inflammatory frequent urination include urgency and pain when urinating, accompanied by fever; non-inflammatory frequent urination is manifested in an increase in the number of urinations, and there is no pain.

1. Clinical manifestations

Non-inflammatory urinary frequency is characterized by increased frequency of urination but without pain. Under the stimulation of inflammation, frequent urination, urgency and pain often occur at the same time, and sometimes there may be fever.

2. Diagnosis

1. Physiological

It is normal to urinate more frequently due to drinking too much water, being stressed or in cold weather. The characteristic is that the amount of urine each time is not small, and it is not accompanied by other symptoms such as frequent urination and urgency.

2. Pathological

The following situations are common:

(1) Polyuria: Frequent urination means the number of urination increases but the amount of urine each time is not small, and the total daily urine volume increases. Seen in diabetes, diabetes insipidus, psychogenic polydipsia and the polyuria phase of acute renal failure.

(2) Inflammatory urinary frequency: Frequent urination with small amount of urine each time, often accompanied by urgency and pain when urinating. Inflammatory cells can be seen in urine microscopy. It is seen in cystitis, urethritis, prostatitis and paraurethral glanditis, etc.

(3) Neurogenic urinary frequency: Frequent urination with small urine volume each time, without urgency or pain, and no inflammatory cells in urine microscopic examination. Seen in central and peripheral neuropathy such as hysteria and neurogenic bladder.

(4) Frequent urination due to reduced bladder capacity is characterized by persistent frequent urination that is difficult to relieve with medication and results in small amounts of urine each time. It is seen in bladder space-occupying lesions; compression of the bladder by the enlarged uterus during pregnancy or ovarian cysts; and fibrous constriction of the bladder caused by bladder tuberculosis.

(5) Lesions around the urethral opening: Urethral polyps, hymenal fimbriae and paraurethral gland cysts stimulate the urethral opening and cause frequent urination.
