A burning or painful sensation during urination is medically known as dysuria. It is more common in women than in men. In men, it is more common in older, rather than younger men. These are some of the more common causes of painful or burning urination: Urinary tract infections (UTIs) are one of the leading causes of painful urination.
Dysuria is an extremely common symptom in women, but it can occur in men and can occur at any age. Dysuria results from irritation of the bladder trigone or urethra. Inflammation or stricture of the urethra causes difficulty in starting urination and burning on urination. Irritation of the trigone causes bladder contraction, leading to frequent and painful urination. Dysuria most frequently results from an infection in the lower urinary tract, but it could also be caused by an upper UTI. Impaired renal concentrating ability is the main reason for frequent urination in upper UTIs.
