Ureterocolic fistula in the presence of a solitary kidney.

Among the entero-urinary fistulae, those between the ureter and colon are rare. Most spontaneous ureterocolic fistulae are caused by urinary calculi. We report a case of a spontaneous ureterocolic fistula which occurred as a consequence of diverticular disease. This rare presentation was further complicated as it occurred in the presence of a solitary kidney. The patient underwent a laparoscopic defunctioning loop ileostomy and after 6 weeks underwent definitive surgical treatment of the ureterocolic fistula. We describe the presentation and management of this fistula and review the current literature.
