Abstract
The case of a patient with emphysematous cystitis who presented with complaints of lower abdominal pain, dysuria, and pneumaturia is presented. The presenting symptoms, differential diagnosis, and radiographic and cystoscopic appearances of emphysematous cystitis, a rare complication of lower urinary tract infection occurring almost exclusively in diabetics, are reviewed. Treatment consists of urinary drainage, prompt initiation of antibiotic therapy, and strict glucose control. The prognosis usually is excellent. © 1990 American College of Emergency Physicians.
