What is the medical name for the bladder inflammation often associated with painful urination?

The medical name for bladder inflammation is cystitis. This condition typically arises due to an infection, irritation, or other underlying causes, leading to symptoms like painful urination, frequent urge to urinate, and discomfort in the pelvic region. Cystitis is specifically localized within the bladder itself, which distinguishes it from other forms of inflammation related to the urinary tract.

Urethritis, while it also involves inflammation and pain during urination, specifically affects the urethra, not the bladder. Nephritis pertains to inflammation of the kidneys, and glomerulonephritis is a specific type of nephritis that involves inflammation of the glomeruli, the filtering structures of the kidneys. Therefore, these conditions are not directly linked to bladder inflammation, reinforcing cystitis as the correct identification for this particular issue.
