The lumbosacral angle is a significant predictor for using a semi-rigid ureteroscopic approach in middle ureteral stones.

ABSTRACT:

Background

Ureteroscopy for middle ureteral stones is often difficult from an anatomical view. This study aimed to evaluate the pelvic anatomy in three dimensions and investigate the relationship between the pelvic anatomy and potential semi-rigid ureteroscopic approach for treating middle ureteral stones.

Methods

From a total of 967 patients who underwent ureteroscopy from December 2017 to January 2021, 124 patients who had middle ureteral stones were included in this retrospective cohort study. The pelvic transverse diameter, pelvic vertical diameter, pelvic depth, and lumbosacral angle were measured through preoperative non-contrast computed tomography to define the shape of the pelvic cavity. The relationship between the reachability of the middle ureteral stone using a
