A decision was made not to balloon dilate the stricture with a high risk of failure given the length of obstruction (Figure 1).
MRI shows a dilated right proximal ureter and pelvicalyceal system.

A follow-up MRI was obtained which revealed mild pelvicaliectasis of the right kidney with ureteral narrowing in the region of the proximal ureter (Figures 2 and 3).
MRI shows encasement of the proximal right ureter, which intraoperatively was found to be due to a fibrous sheath.
