How To: Smartphone Assessment of Penile Deformity

Another example of  researchers bending new technology to meet their desires:

Holt, Thomas J. Walsh, Journal of Sexual Medicine, epub April 3, 2013. The authors, at the University of Washington, reveal their method:

“To assess penile curvature, 15 single cylinders of malleable penile prostheses were molded to varying curvature angles. Three blinded observers nonsequentially measured the angle of curvature for each prosthetic cylinder using a protractor, goniometer, and UWPEN [the University of Washington Peyronie's Examination Network]. To assess girth narrowing, six clay models of the penile shaft were constructed to represent conditions of normal, partial hourglass, circumferential hourglass, and pencil narrowing. Girth was measured using a ruler and UWPEN by the same blinded observers.”
