Ureterocolic Fistula Secondary to Diverticulitis of the Sigmoid Colon after Laparoscopic Salpingo-Oophorectomy: A Case Report and Literature Review

Figure 3

Right retrograde pyelography demonstrating stricture of the right ureter (arrow) and its deviation to the left side, from which a fistula into the sigmoid colon is observed (arrowheads). Extravasation of contrast into the mid-pelvis is also present right above the narrowing of the ureter (hollow arrow), suggestive of a fistula to the peritoneum.
