Burning sensation in the urethra

Introduction The urinary tract burning sensation and pain associated with urination are clinically significant symptoms of urethritis. There are ascending and descending infections in the infection route. According to the different pathogenic bacteria can be divided into: 1 non-specific urethritis, pathogenic bacteria are Escherichia coli, Streptococcus and Staphylococcus are the most common; 2 specific urethritis, also known as gonorrhea urethritis.

Cause

(1) Causes of the disease

The common causes of urethritis are as follows:

1 urethral injury: urethral mucosal abrasion caused by urethral instrument examination can destroy the urinary tract mucosal defense function, leading to bacterial infection.

2 Foreign bodies in the urethra: Foreign objects placed in the outside world or stones in the urethra, etc., stopping for a long time can cause urinary tract infection.

3 urethral obstruction: such as stenosis of the foreskin, urethral stricture, urethral stricture, posterior urethral valve, urethral tumor, female hymen umbrella, urethra hymen fusion, etc., due to poor urination, urine accumulation in the urethra can be secondary urinary tract infection . 4 adjacent organ inflammation, such as prostatitis, seminal vesiculitis, vaginitis or uterus

Puncture and the like can spread to the urethra, which is often a stubborn lesion of chronic posterior urethritis. 5 often associated with sexual life, unclean sex can easily cause urinary tract infections.

(two) pathogenesis

There are ascending and descending infections in the infection route. According to the different pathogens, it can be divided into:

1 non-specific urethritis, pathogenic bacteria are most common with Escherichia coli, Streptococcus and Staphylococcus. .

2 specific urethritis, also known as gonorrheal urethritis (gonorrheal urethritis), referred to as gonorrhea (gonorrhea), the pathogen is Neisseria gonorrhoeae; 3 non-gonococcal urethritis, the pathogen is trachoma Chlamydia, Ureaplasma urealyticum, Brevibacterium haemophilus, fungi, Trichomonas vaginalis, condyloma acuminata and herpes simplex virus.

In acute inflammation of the urethra, the urethra is red and swollen, and the margins are everted. The mucosal surface is often adhered by serous or purulent secretions, sometimes with superficial ulcers. Microscopic mucosal edema can be seen, in which white blood cells, plasma cells and lymphocytes infiltrate, capillaries are obviously dilated, and the paraurethral glands are hyperemia or filled with piles of pus cells.

Chronic urethritis lesions are mainly in the posterior urethra, bladder neck and bladder triangle, sometimes spreading throughout the urethra. The surface of the urethral mucosa is dark red granules, and the urethral orifice is smaller than normal due to scar contraction. Microscopically, lymphocytes, plasma cells and a few white blood cells were seen, and fibroblasts increased.

Frequent urination, burning pain and hematuria. In the acute phase, men may have urethral secretions, which begin with mucus, and then have a lot of purulent secretions; women have few secretions. When converted to chronic, it is characterized by urethral tingling and urination discomfort, and the secretion of urethra is reduced, showing a thin slurry. In the acute attack, there is dull pain in the suprapubic region and the perineum. It can be seen that the urethra is red and has secretions.

In addition to the history and physical signs, the diagnosis of urethritis requires urethral secretion smear examination or bacterial and mycoplasma culture to identify pathogenic bacteria. Diagnosis of urethritis is not difficult, but attention should be paid to the diagnosis and treatment of the primary disease and related diseases. Male patients should have three cups of test if they have no urethral secretions (ie, anterior urethritis, first cup of urine turbidity, a large number of pus cells, white blood cells, 2nd and 3rd cups clear. Posterior urethritis, 1st and 3rd cups are turbid, there are a lot of Pus cells, white blood cells, the second cup is clear). In the acute phase of the urethra, avoid using equipment examination. Chronic urethritis requires a urethral cystoscopy to determine the cause of the disease. Metal urethral strips can sometimes be used to test for stenosis in the urethra and urethrography if necessary.

Differential diagnosis

Itchy urinary tract, burning sensation during urination is a diagnostic symptom of fungal urethritis. Fungal urethritis is a urethral inflammatory lesion caused by mold.

Urethral itching: A slight burning sensation in the urethra when urinating, itching is a common symptom of urethritis. Urethritis is a common disease, more common in women, clinically divided into acute and chronic, non-specific urethritis and gonococcal urethritis, the latter two clinical manifestations are similar, must be identified according to medical history and bacteriology. Intraurethral insect bites or vaginal worms: Most of the sexually transmitted diseases have fear, anxiety, or depression, self-reported dizziness, headache, insomnia, nightmares, palpitations, loss of appetite, tinnitus, and fatigue. Frequent urination is not complete, or urinary tract itching, pain and discomfort, there is "secretion" in the urethra. Scrotum, lower abdomen pain and discomfort, back pain, and nocturnal emission, premature ejaculation, irregular menstruation, decreased sexual desire. In severe cases, you may feel allergic symptoms such as worm in the urethra or vaginal crawling.
