We studied 164 patients with Peyronie's disease, 34 of whom have clinical symptoms of erectile dysfunction. Dopplerography has detected alterations of penile hemodynamics in 71.8% cases. Vein occlusive dysfunction prevailed (54.8%). Dopplerographic signs of venoocclusive dysfunction were seen also in patients with minor erectile disorders (55.4%). The analysis of absolute values of the systolic velocity peak allowed us to consider values in the range > 25 but < 35 cm/s as borderline or suboptimal, corresponding to subclinical period of venoocclusive dysfunction. Dynamic cavernosometry results served the basis for criteria of subclinical venoocclusive dysfunction characterized by threshold intracavernous pressure 50 mm Hg, coefficient of 30-s reduction of intracavernous pressure from 1.75 +/- 0.93 to 2.1 +/- 0.8 mm Hg and supporting perfusion velocities under 29.2 +/- 15 ml/min. Characteristics of hemodynamic status and penile geometry help an optimal choice of deviation correction in patients with Peyronie's disease.
