The PDAD was designed for objective assessment of penile deformity due to Peyronie’s disease. It is a simple-to-use, disposable device for measuring penile curvature, depth of penile indentations, and stretched-flaccid penile length.
Enhancing patient perception Acts as a ruler to measure stretched flaccid or erect penile length. Also measures the degree of curvature rather than relying on photographs or patient reported curvatures which can be inaccurate.
Formally documenting penile curvature Supports the diagnosis of Peyronie’s disease and justification for penile ultrasound.
Peyronie’s disease treatment monitoring Patients who elect non-surgical management can monitor their progress by serial curvature assessments using the PDAD at home and physicians can monitor their progress in the office by performing repeat curvature assessment after pharmacologic induction of erection (with or without penile ultrasound).
Instructions for use
PENIS HAS TO BE IN MAXIMUM ERECTILE STATE BEFORE BEGINNING MEASUREMENTS.
- At the end of the short arm is a small tab for measuring penile indentation. With the end of the long arm directed perpendicular to the penis at the point of indentation, this small tab can be extended directly into the indented space. Markings on the tab are then used to measure the depth of the indented space.
- Then rotate the long arm of the PDAD until the cut out slit is aligned with the middle of the penis shaft above the curvature.
- Carefully remove the PDAD from the penis and read the angle of curvature indicated on the PDAD adjacent to the indicator angle arrow. Record the angle and make sure each subsequent measurement is always performed with the penis in the maximum erectile state.
