A 71 year-old man with dysuria for one month but failed in management of infectious urinary system. The patient noted foaming at his penis after urination.
Ultrasound detected gas in urinary bladder and thickening of sigmoid colon. May it exists a fistula of colon and urinary bladder as appearance ò foaming at the penis.
Endoscopy revealed colonic diverticula.
Cystoscopy showed acute cystitis but not ruling out a colonobladder fistula.
MSCT confirmed the tract between the sigmoid colon and urinary bladder and colonic diverticula.
