The endocavity balloon or standoff covers the endorectal ultrasound transducer during transrectal procedures, enabling
ultrasound scanning. Inflating
and deflating the balloon with saline during transrectal scanning assists with
positioning the prostate. Use of an endocavity
balloon to cover the ultrasound transducer during template-guided transperineal
biopsy enables access to the peripheral zone at the level of the prostate base.1
The endocavity balloon is not made with natural rubber latex.
