[The rigidometer]

Fifty patients with erectile dysfunction were evaluated with the Rigidometro (CUASBA) penile rigidity monitor and the data were compared with those obtained with the erectometer device for nocturnal monitoring with the Ambulatory Rigidity Tumescence Monitor (ART 1000, Surgitex) penile rigidity monitoring following intracavernal injection of vasoactive agents. Similar results were observed. In our view, the Rigidometro (CUASBA) provides reliable information comparable with those provided by other monitoring devices. It gives very precise data on the quality of erection achieved. It is inexpensive and easy to-use. All the foregoing make it a useful tool in the diagnosis and evaluation of erectile dysfunction.
