Abstract
A 47 year old man with no past medical history presented to the urology clinic with recurrent urinary tract infections caused by E.Coli. He subsequently had a number of investigations including imaging and cystoscopy which showed a high possibility for a colovesical fistula and incidentally demonstrated subdiaphragmatic Situs inversus. The sigmoid colon was inflamed and adherent to the posterior wall of the bladder.
Surgical management following a multi-disciplinary decision resulted in an elective Ureteric stent insertion followed by laparotomy with sigmoid colectomy and primary anastomosis. The bladder wall defect caused by fistula formation was repaired.
We report an extremely rare case of colovesical fistula in the setting of subdiaphragmatic situs inversus in a relatively young patient.
This would likely be seen in older patients with more severe diverticulitis and usually in an acute setting. Anatomical variation resulted in more severe diverticular disease and predisposed to fistula formation.
