What does 'dysuria' primarily affect?

Dysuria is a medical term that refers specifically to painful or difficult urination. It primarily affects the urinary system and is characterized by discomfort or an abnormal sensation during the process of urination. This condition is often associated with urinary tract infections, inflammation, or other issues affecting the bladder or urethra. The focus on urination is what makes this term relevant and distinct from other bodily processes, such as vision, breathing, or digestion. Each of those systems deals with entirely different physiological responses and health concerns.
