..., and radial rigidity at the tip (p = 0.0024) and base (p = 0.0098) of the penis. In 10 patients, the DIR revealed axial rigidity of 550 g or more, and they also had radial rigidity of 60% or more at the tip and base. In 14 and 17 subjects, radial rigidity of 60% or more was observed at the tip and base...

... by intracavernous injections of prostaglandin E 1 in 43 patients and to compare ICP with radial rigidity estimation in 13 impotent men undergoing cavernosometry. Calculation of the rigidity index using the skin fold caliper was based on the girth change of the penis shaft when the caliper’s jaws exerted a constant...
