ABSTRACT: Purpose: There has been no report evaluating the anatomy of the ureter on
CT images. The purpose of this study was to retrospectively evaluate the
anatomy of the ureter near the ureterovesical junction on preoperative CT.
Methods: Forty patients were analyzed the craniocaudal level of the
ureterovesical junction, the transverse distance from the medial line of the
body to the ureterovesical junction, the direction of the ureter from the
ureterovesical junction, and the length of the ureter from the point of turning
medially to the ureterovesical junction. Results: The ureterovesical junction
was almost at the level of the upper or middle of the left femoral head. The
mean transverse distance on the right and left side was 19.0 and 19.3 mm. The
direction of the ureter was almost posterior, lateral, and cranial, but had a
wide range of angles. The mean length of the ureter on the right and left side
was 24.0 and 23.9 mm. Conclusions: We can evaluate the anatomy of the ureter
near the ureterovesical junction on preoperative CT.
