Overview

Dysuria is define as pain or burning, stinging, or itching of the urethra or urethral meatus during or just after urination.
Dysuria happens due to bladder muscle contraction and peristalsis of the urethra, which cause the urine to come in contact with the inflamed mucosal lining, which in turn stimulates pain receptors and causes one to feel pain or burning.

Epidemiology

  • Dysuria can happen in both males and females. One of the most common causes of dysuria is urinary tract infection. Urinary tract infections are more common in females than males due to female anatomy, having a shorter and straight urethra compared to males who have longer and curved urethra due to male anatomy.
  • In females, bacteria can reach the bladder more easily due to shorter and straight urethra as they have less distance to travel.
  • females who use the wrong wiping technique from back to front instead of front to back can predispose themselves to more frequent urinary tract infections due to the opening of the urethra being closer to the rectum. Because of these reasons, females tend to experience dysuria more frequently compared to males.

Pathophysiology

  • Dysuria from inflammatory causes like urinary tract infection results from bladder muscle contraction and urethral peristalsis, causing urine to come in contact with inflamed mucosa.
  • This contact causes stimulation of sensory nerves and pain receptors and causes pain along with burning, stinging, or itching.
  • The sensitivity of these receptors can become enhanced during the inflammatory or neuropathic processes
  • Inflammation from the surrounding organs such as colon can also sometimes result in dysuria.
  • Dysuria from non-inflammatory causes like stone, tumor, trauma, or foreign body can cause irritation of the urethral or bladder mucosa .

Classification

Dysuria can be divided broadly into two categories

Causes in Alphabetical Order

Treatment

Treatment of dysuria depends on its cause the most common cause of dysuria is urinary tract infection for which empiric antibiotic are used.
If the cause of dysuria is renal stones, then various treatment options can be considered depending on the size and location of stones. Stones smaller than 5 mm typically pass on their own, and patients should be asked to hydrate themselves and strain the urine to document the evidence of a passed stone. The stones that are bigger than 5 mm are treatable through various modalities, including extracorporeal shock wave lithotripsy (ESWL) or percutaneous nephrolithotomy (PCNL) or open surgery.

When dysuria is occurring due to chronic prostatitis in males, oral antibiotics merit consideration after obtaining urine culture.
