I have what doctors seem to think is a colovaginal fistula caused from a hysterectomy five years ago. I’ve had several tests and it doesn’t show up on film or during a physical examination. I have a CT scan scheduled and consultation with two surgeons (rectovaginal and gynecological). One is not convinced I have this condition. I have fecal particles in my urine and vaginal flatulence. Any ideas in what else this could be if not a fistula? My doctor from home is convinced it’s what I have.
