Cystitis is an inflammatory condition that occurs in the bladder and is mainly caused by specific and nonspecific bacterial infections, as well as other specific types of cystitis. Atopic infections refer to tuberculosis of the bladder. Nonspecific cystitis is caused by Escherichia coli, E. coli, E. parapsilosis, Pseudomonas aeruginosa, Streptococcus faecalis, and Staphylococcus aureus. The clinical manifestations are both acute and chronic. The former has a sudden onset, a burning sensation during urination, and pain in the urethral region.
Sometimes there is urinary urgency and severe urinary frequency. It is common in women. Terminal hematuria is common, and in severe cases there is discharge of meatus hematuria and blood clots. Symptoms of chronic cystitis are similar to those of acute cystitis, but without high fever. Symptoms may last for several weeks or may come in intermittent episodes, leaving the patient weak and lethargic, with uncomfortable or vague pain in the lower back and perineal area of the bladder.
