As part of the study, an abdominal ultrasound was performed, in which, in addition to stones in the gallbladder, a multicystic lesion was evidenced in the upper pole of the left kidney, 2.5 cm in diameter, well defined, with solid heterogeneous areas, Bosniak III.

The lesion was resected (partial nephrectomy). Look at the pictures.
