Most chronic cystitis is caused by bacterial infections, both specific bacterial infections such as tuberculous cystitis and nonspecific bacterial infections such as Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Streptococcus faecalis, and Staphylococcus aureus. There are also more specific cystitis such as interstitial cystitis and glandular cystitis. The main symptoms are frequent, urgent, and painful urination usually without fever, and the symptoms can last for weeks, months, or intermittent episodes. If the chronic cystitis is caused by a non-specific bacterial infection, most of them can be cured with regular treatment with antibodies and attention to life care. Even specific bacterial infections, such as tuberculous cystitis, can be cured with regular antituberculosis treatment, but the treatment period will be longer. Some specific types of cystitis, such as interstitial cystitis and chemical cystitis, do not respond to antibiotic therapy and often require surgical intervention, but the results are not ideal. In summary, there are more types of chronic cystitis, and if the cystitis is caused by a bacterial infection, most can be cured with regular anti-inflammatory treatment. In contrast, certain specific types of chronic cystitis are not treated well.
