Differential Diagnosis for Dysuria in a 44-year-old Man

Single Most Likely Diagnosis

  • Urinary Tract Infection (UTI): This is the most common cause of dysuria in men, especially if they have a history of UTIs or recent instrumentation of the urinary tract. Bacterial infections, such as those caused by E. coli, are the most frequent etiology.

Other Likely Diagnoses

  • Prostatitis: Inflammation of the prostate gland can cause dysuria, and it's more common in younger men. The symptoms can include pain in the perineum, frequent urination, and difficulty starting urination.
  • Urethritis: Infection or inflammation of the urethra can cause dysuria. This is often due to sexually transmitted infections (STIs) like gonorrhea or chlamydia, but it can also be caused by other bacteria.
  • Kidney Stones: While not always causing infection, kidney stones can irritate the urinary tract and cause dysuria, especially if they are moving down the ureter.

Do Not Miss Diagnoses

  • Gonorrhea or Chlamydia: These STIs can cause severe complications if not treated promptly, including infertility and epididymitis. They often present with dysuria and discharge.
  • Tuberculosis of the Urinary Tract: Although rare, TB can infect the urinary tract and cause dysuria, among other symptoms like hematuria and flank pain. It's crucial to consider in high-risk populations or those with systemic symptoms.
  • Cancer of the Urinary Tract: While less common, cancers of the bladder, prostate, or kidney can cause dysuria, especially if there's associated hematuria.

Rare Diagnoses

  • Interstitial Cystitis: A chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain. The symptoms can include dysuria, but it's more commonly associated with frequency and urgency.
  • Sjögren's Syndrome: An autoimmune disorder that can affect the bladder and cause dysuria, among other systemic symptoms like dry eyes and mouth.
  • Schistosomiasis: A parasitic infection that can cause urinary symptoms, including dysuria, especially in individuals who have traveled to or lived in endemic areas.
