Dysuria refers to discomfort, burning, or sensation of pain during micturition. Patients may also complain of urethral discomfort not associated with micturition. Dysuria may be external (i.e., urine irritating the inflamed genital organs) or internal (i.e., pain felt in the urethra).
Although urinary tract infection is the most common cause, any infectious or inflammatory condition affecting the genitourinary system may cause dysuria.
Dysuria is a common presentation in primary care. It is generally more common in women, with a reported prevalence in women of up to 25% in the US per year and 27% in the UK per year. Approximately 1 million urinary tract infections are treated every year in US emergency departments, with a female:male ratio of 6:1.
Although dysuria is uncommon in men, incidence increases with advancing age. Lower urinary tract symptoms increase dramatically in men aged >40 years due to bladder outlet obstruction secondary to benign prostatic hyperplasia. Among men of all ages who seek medical advice for urological symptoms, dysuria is present in about 5% of cases.
