Which condition involves painful urination?

Dysuria is the term used to describe painful or difficult urination. This condition can be caused by various issues, including urinary tract infections, inflammation, or irritation in the urinary tract. When a person experiences dysuria, they often feel a burning sensation or discomfort while urinating, which is a key characteristic of the condition.

While cystitis refers to inflammation of the bladder, which can indeed result in dysuria among other symptoms, it does not specifically denote the painful urination itself. Diuresis relates to increased urine production, which does not imply pain, and pyuria refers to the presence of pus in the urine, typically indicating infection or inflammation, but again, it does not directly point to the experience of pain during urination. Therefore, dysuria is the most accurate term to define the condition of having painful urination.
