1. An ultrasound diagnostic apparatus comprising:
an ultrasound probe;
an input device configured to accept an input operation of a user;
a processor configured to
acquire ultrasound images of a plurality of frames through a scan with an ultrasonic beam on a subject using the ultrasound probe,
extract a urinary bladder region from each of the ultrasound images of the plurality of frames,
calculate a feature quantity related to a size of the urinary bladder region extracted for each of the ultrasound images of the plurality of frames,
determine whether or not each of the ultrasound images of the plurality of frames is of a failed frame for which the scan with the ultrasonic beam on the subject has failed,
determine whether or not a rescan with the ultrasonic beam is needed, based on a time-series change in the feature quantity and a position on a time of the ultrasound image of the frame determined to be the failed frame,
upon determining that the rescan with the ultrasonic beam is needed,
recommend the rescan with the ultrasonic beam to the user,
receive a selection of whether or not to perform the rescan with the ultrasonic beam, in accordance with the input operation performed by the user via the input device,
upon determining that the rescan with the ultrasonic beam is not needed or receiving a selection of not performing the rescan with the ultrasonic beam,
