A sacral nerve stimulation (SNS) device is seen in place; its pulse generator is noted in the subcutaneous soft tissues of the right buttock and its electrode lead can be followed from the pulse generator traversing the subcutaneous tissues of the back and entering the left sacral foramen at S4 level with its tip lying in a pre-sacral location at S5 level. No signs of infection (fat stranding, free fluid, or collection) are seen in the soft tissues around the pulse generator. Coarse calcifications are noted in the prostate gland. No suspicious osseous lesion is seen in the visualized skeleton.
