目的分析血管性勃起功能障碍(ED)病人阴茎血流动力学的变化,提高对该病的诊断和治疗水平。方法对52例血管性ED病人分别采取海绵体内注射试验和阴茎彩色双功能超声等检查,分析其血流动力学变化。结果52例血管性ED(动脉性ED14例,静脉性ED26例,混合血管性ED12例)病人在阴茎勃起的充盈、勃起、充分勃起和强直勃起期均有明显不同的血流动力学变化,表现为充盈、勃起期延长,充分勃起和强直勃起减少等。结论血管性ED会发生明显的阴茎血流动力学变化,了解该变化有助于其正确诊断和采取适当的治疗方法。 Objective To analyze the changes of penile hemodynamics in patients with vascular erectile dysfunction (ED) and to improve the diagnosis and treatment of the disease. Methods Fifty-two patients with vascular ED were examined by intracavernous injection and colorimetric bi-functional ultrasound. The hemodynamic changes were analyzed. Results 52 patients with vascular ED (arterial ED 14, venous ED 26, mixed vascular ED 12) showed significant hemodynamic changes in penile erection filling, erection, full erection and atrophic erection For filling, prolonged erection, full erectile and erectile reduction and so on. Conclusion Vascular ED will have significant penile hemodynamic changes, understanding the changes help to correct diagnosis and take appropriate treatment.
