title: Multifactorial evaluation of diabetic erectile dysfunction.
abstract: We determined arterial venous and sinusoidal factors in 20 patients with insulin dependent diabetes mellitus and erectile dysfunction by performing dynamic infusion cavernosometry (DIC), colour flow Doppler ultrasonography, penile biothesiometry and corpus cavernosum electromyography (CCE). DIC, colour flow Doppler ultrasonography and penile biothesiometry were done in standard fashion except for CCE. Paradoxical increase in the electrical activity of corpus cavernosum after intracavernous (IC) papaverine was called a discoordination that was due to cavernous smooth muscle contraction instead of relaxation. Arterial and accompanying pathologies were found in 10 (50%) patients. In 3 (15%) of them pure arterial pathology, in 6 (30%) patients arterial and veno-occlusive dysfunction (VOD) and in one patient arterial pathology with abnormal biothesiometry were found. VOD and accompanying pathologies were found in 12 (60%) patients. In 6 (30%) of them VOD and arterial, in 4 (20%) patients VOD and discoordination and in 2 (10%) patients VOD and abnormal biothesiometric values were present. A higher frequency and coexistence of VOD and discoordination pattern were observed. In conclusion, patients with diabetic impotence show a wide range pathophysiology of erection and the evaluation of these patients must include multistep techniques.
