Urethral itching
Introduction
Introduction A slight burning sensation and tingling sensation of the urethra during urination are common symptoms 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. Urinary frequency, urinary burning pain and hematuria, acute men may have urethral secretions, beginning with mucinous, followed by a lot of purulent secretions; women have few secretions, when converted to chronic urethral tingling and urination discomfort, The secretion of urethra is reduced, and it is in the form of a thin serous fluid. There is dull pain in the suprapubic area and perineum in the acute attack. It can be seen that the urethra is red and has secretions.
Cause
Cause
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 cervicitis 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.

Urine routine examination showed leukocytosis or pyuria, accompanied by erythrocytosis, a small number of gross hematuria. Three cups of urine test, it can be found that a large number of pus cells and red blood cells exist in the first cup, while the second cup and the third cup are basically normal. The number of urinary cell culture bacteria in the first stage was significantly higher than that in the middle stage. Stenosis of urethra or vaginal secretions, gonococcal urethritis can be seen intracellular or extracellular gonorrhea, non-specific urethritis can be cultured with secretions or anterior urethra swabs, see a large number of bacterial growth. No secretions were found in the smears and cultures of the secretions, that is, the possibility of infection with mycoplasma and chlamydia, and special methods of culture or PCR examination were possible.
Chronic urethritis requires urethroscopic cystoscopy to determine the cause of the disease. Metal urethral probes can sometimes be used to test for stenosis in the urethra and urethrography if necessary. In the acute phase of the urethra, avoid using equipment examination.
Diagnosis
Differential diagnosis
Urethral itching: Burning sensation during urination is a diagnostic symptom of fungal urethritis. Fungal urethritis is a urethral inflammatory lesion caused by mold.
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.
Urinary tract burning sensation: urinary tract burning sensation and pain are clinically significant symptoms of urethritis. 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.
