Which of the following defines dysuria?

Dysuria specifically refers to the sensation of pain, burning, or discomfort during urination. This term is commonly used in medical contexts to describe a symptom associated with various conditions, such as urinary tract infections, sexually transmitted infections, or inflammation of the urinary tract. The key factor that defines dysuria is the presence of pain when urinating, making it distinct from other urinary symptoms.

Frequent urination pertains to the need to urinate often but does not involve pain. Blood in urine, known as hematuria, indicates the presence of blood and suggests a different set of medical concerns. Inability to urinate, referred to as urinary retention, is a condition where one cannot pass urine at all and does not relate to the painful sensation associated with dysuria. Thus, the definition of dysuria centers on the experience of pain during urination, confirming that the answer is indeed correct.
