Color Doppler ultrasound assessment of penile vascular system in men with Peyronie's disease

The purpose of this study was to evaluate the penile vascular function by color Doppler ultrasonography (CDU) in patients with Peyronie's disease. A total of 136 men with Peyronie's disease were strati®ed according to their potency by history as Group I consisting of potent patients and Group II consisting of patients with erectile dysfunction. They were all evaluated by penile CDU.Overall, 70.6% had erectile dysfunction by history. CDU revealed penile vascular abnormalities in 76.5%. In Group I, veno-occlusive dysfunction (VOD) was observed in 40% while mixed (arterial venous) vascular disease was diagnosed in 10%. Penile vascular disease was detected in 87.5% patients in Group II (ie VOD in 28%, arterial disease in 9.3% and mixed vascular disease in 50%). The prevalence of arterial disease on CDU among Peyronie' patients with erectile dysfunction (59.3%) was signi®cantly (P`0.05) higher then it was among potent patients (10%). The prevalence of pure VOD was almost similar for patients with or without erectile dysfunction (P`0.05).We conclude that penile vascular abnormalities can be observed in 76.5% on cases with Peyronie's disease by CDU and this ratio signi®cantly increases to 87.5% among cases with erectile dysfunction by history. Our data also indicate that arterial disease, accounts for much of the diminished rigidity in men with Peyronie's disease.

Peyronie's disease in men under age 40: characteristics and outcome

et al. 2001

View full text Add to dashboard Cite

Peyronie's disease is most commonly seen in the ®fth decade of life. However, a wide range of age (20 ± 83 y) is reported. During a 6-year period, men with Peyronie's disease presenting under the age of 40 were reviewed retrospectively and followed-up. The prevalence of Peyronie's patients presenting under age 40 was 8.2%. Their mean age was 32.47 AE 5.37 (range: 23 ± 39) y and 78.9% of them presented during the acute phase of the disease. Pain on erection was a part of presenting symptom complex in 52.6% and the majority (84%) had a degree of penile curvature`60 . Erectile dysfunction (ED) was present in 21% of patients, who responded well to intracavernous injection test. After a minimal 2-year follow-up, improvement in penile deformity was observed in 36.8%, and 42.1% had stable disease while 21% experienced deterioration of the penile curvature. The onset of Peyronie's disease is clinically more noisy and acute in patients presenting under age 40 and this forces the physicians to treat them more vigorously.

Hemodynamic Patterns of Pharmacologically Induced Erection: Evaluation by Color Doppler Sonography

Abstract: Erection is a complex and dynamic process. A new classification of hemodynamic patterns is presented that aids in assessing and interpreting more thoroughly blood flow parameters to stratify more precisely the hemodynamic patterns of erectile dysfunction.
