Urinary Actinomyces infection with a urachal remnant

Riku Kashiwagi et al. BMJ Case Rep. .

Abstract

Urinary Gram staining is helpful in patients with complicated urinary retention, such as prolonged urinary retention and coexisting ureteral retention disease. If gram-positive rods are observed on urine Gram staining in a patient with urinary tract infection, an anaerobic culture of the urine may be helpful for early diagnosis and treatment of Actinomyces infection.

Keywords: General practice / family medicine; Infectious diseases; Medical education; Urinary tract infections.
