case_images: She was free of complaints, but transvaginal ultrasound showed a hypoechoic cystic shadow adjacent right posteriorly to the uterus (Figure 1).
case_images: Transvaginal ultrasound on postoperative day 62 showing dilated uterine cavity ((a), arrowheads). The cystic echo observed on day 34 still exists but decreased in size ((b), arrows, 29.8 mm x 15.1 mm).

case_images: Transvaginal ultrasound revealed dilated uterine cavity suggestive of fluid retention (Figure 2(a)). The cystic hypoechoic shadow on day 34 still existed but decreased in size (Figure 2(b)).
case_images: 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.

case_images: Retrograde pyelography revealed that the right ureter was narrowed and shifted to the left at the level of the uterosacral ligament, with a fistula leading to the sigmoid colon (Figure 3). 
case_images: Coronal (a) and axial (b) scan of pelvic CT after retrograde pyelography. Contrast used for retrograde pyelography remains in the sigmoid colon (arrow).
