Fig. 1

Fistula location on bladder and patency of the rectovesical pouch were evaluated using preoperative magnetic resonance images (MRI) from a representative case, and the estimated contact area between the sigmoid colon and bladder (eCA) was calculated as the product of the length and width between the sigmoid colon and bladder on two-dimensional MRI. a Fistula is located on the superior wall of the bladder. b Fistula is located in the posterior bladder. c: The patency of the rectovesical pouch is preserved and the fistula can be encircled. d The rectovesical pouch is closed and cannot be approached directly. e Length between the sigmoid colon and bladder on sagittal view. f Width between the sigmoid colon and bladder on coronal view
