This study aims to investigate the anteroposterior urethral diameter and transverse urethral diameter on MRI. Female patients under 50 years without SUI who visited our hospital from April 2014 to March 2022 were included. The opt-out period was from April to October 2022. Among the patients whose urethra was measured by MRI under the same conditions as in the present study, we calculated the following criteria. MRIs were performed at Kanagawa Dental University, Yokosuka Kyousai Hospital, Uwamachi Hospital, and Sent-Yozefu Hospital.
