urethritis Cause

Urethritis is what causes it?

(A) causes of morbidity

Urethritis caused by common causes are as follows: ① urethral injuries: inspection equipment caused by urethral urethral mucosa abrasions, can damage the urethral mucosa defense function, leading to bacterial infection. ② urethral foreign body: a foreign body from outside or within the urethra into the stone and so on, pause a little longer to result from urinary tract infection. ③ urethral obstruction: If the foreskin stenosis, urethral stenosis, urethral stricture, posterior urethral valves, urethral cancer, female hymen umbrellas hymen integration urethra due to poor urination, urine stored in the secondary urinary tract infections within the urethra . ④ inflammation of adjacent organs, such as prostatitis, Vesiculitis, vaginitis, or cervical Yandeng can be spread to the urethra, this often chronic urethritis after a stubborn lesions. ⑤ often associated with sexual activity related to unclean sex life could easily cause a urinary tract infection. from http://www.tcmwell.com

(Ii) the pathogenesis of

Routes of infection are ascending infections and descending infections. According to the different pathogens can be divided into: ① non-specific urethritis, pathogenic bacteria Escherichia coli, Streptococcus and Staphylococcus are the most common; ②-specific urethritis, also known as gonorrheal urethritis, referred to as gonorrhea, pathogen Neisseria gonorrhoeae; ③ non-gonococcal urethritis, pathogen Chlamydia trachomatis, Ureaplasma urealyticum, Haemophilus short bacilli, fungi, Trichomonas vaginalis, genital warts, and herpes simplex virus.

Acute urinary tract inflammation, urethral mouth swelling, the edge turned outward, and mucosal surfaces are often serous or purulent secretion bonding, sometimes superficial ulcers. Endoscopic mucosal edema can be seen, including white blood cells, plasma cells and lymphocytes infiltration, capillary notable expansion of the paraurethral glands or congestive heart by filling piles of pus cell.

Chronic urethritis lesions mainly in the posterior urethra, bladder neck and bladder triangle, and sometimes spread throughout the urethra. Urethral mucosal surface roughness Chenganhongse granular, due to scar contraction, urethral mouth smaller than normal. Microscope, lymphocytes, plasma cells and a few white blood cells, fibroblasts increased. http://www.tcmwell.com
