Abstract
One of the most common chronic dysfunction in men over 40 years of age is erectile dysfunction (ED). The prevalence and severity of ED increases with age and the presence of comorbid conditions — type 2 diabetes, visceral-abdominal obesity, hypertension and cardiovascular diseases. Most cases of ED is the result of hemodynamic dysfunction of arterial insufficiency (80%) or venous insufficiency. One of the most accurate indicators in the diagnosis of arterial hemodynamic disturbances is duplex ultrasound vessels examination. Purpose — to explore the features in vasсulogenicviolations of erectile dysfunction in patients with type 2 diabetes using penile duplex ultrasound scan of the vessels. Materials and
methods. Defining the penile blood flow mode duplex ultrasound scanning 27 men conducted in patients with type 2 diabetes and ED (average age 50.1±1.2 years, duration of diabetes — 9.1±2.0 years, duration of ED — 4.7±2.2 years). Results. In patients with type 2 diabetes and ED a reduction in blood flow peak systolic velocity a. dorsalis penis (22.0±0,6 cm/sec) was showed compared with men in the control group (24.8±0.8 cm/sec, р<0,01). Resistant (Ri) and pulsatile indices (Pi) of a. cavernosum were significantly lower in patients with diabetes than in men of the control group at rest. The response to pharmacological induction of erection in patients with type 2 diabetes was less intense than in men of the control group at the 5th, 15th, 30th min. Conclusions. Identified reduce resistance index and pulsating index in patients with type 2 diabetes and ED compared with men in the control group, both in the resting phase and in the dynamics of pharmacological induction of erection in the study a. сavernosum, indicate the formation of a mixed arterio-venous insufficiency prevalence of blood component in these patients.
