Penile erection is a complex phenomenon that involves coordinated interaction of the psychologic, hormonal, nervous, arterial, venous, and sinusoidal systems. Erectile dysfunction (ED) is the persistent inability to attain or maintain penile erection sufficient for sexual intercourse. This study aims to determine the real-time morphologic vascular abnormalities in men with ED using penile Doppler sonography in Kano, Nigeria.
Twenty-one patients who were referred from urology clinics on account of suspected vasculogenic ED were reviewed. The cavernorsal arteries were examined with 7.5 MHz linear transducer in gray scale and duplex Doppler modes before and after intracavernosal injection of 60 mg papevarine. Serial peak systolic velocity (PSV), end diastolic velocity (EDV), and diameter measurements were performed at 5-min intervals for 30 min.
The mean age of the patients was 43.14 ± 9.84 years. Out of the 21 patients examined, 5 showed normal findings while 10 had evidence of venous leakage. Five patients had arterial insufficiency; out of which 3 patients showed calcifications of the tunica albuginea, suggesting Peyronie's disease. Interestingly, 1 patient showed combining features of arterial insufficiency and of venous leakage. Those with arterial insufficiency were relatively older than other patients. They also had compounding medical conditions of diabetes and hypertension.
Vascular etiologies are important contributors of ED in our setting. Papavarine-induced Doppler sonography and cavernosography shows promise in accurate assessment and overall care of these patients.
阴茎勃起是一种复杂的现象，涉及心理、激素、神经、动脉、静脉和海绵体系统的协同相互作用。勃起功能障碍（ED）是指持续无法达到或维持足以进行性交的阴茎勃起。本研究旨在利用尼日利亚卡诺市的阴茎多普勒超声检查确定勃起功能障碍男性的实时形态学血管异常情况。
对因疑似血管源性勃起功能障碍从泌尿外科诊所转诊的21例患者进行了回顾性研究。在海绵体内注射60mg罂粟碱前后，使用7.5MHz线性换能器以灰阶和双功多普勒模式检查海绵体动脉。每隔5分钟进行一次连续的收缩期峰值流速（PSV）、舒张末期流速（EDV）和直径测量，共测量30分钟。
患者的平均年龄为43.14±9.84岁。在接受检查的21例患者中，5例结果正常，10例有静脉漏的证据。5例有动脉供血不足；其中3例显示白膜钙化，提示佩罗尼氏病。有趣的是，1例患者表现出动脉供血不足和静脉漏的合并特征。有动脉供血不足的患者相对比其他患者年龄大。他们还患有糖尿病和高血压等合并症。
在我们的研究环境中，血管病因是勃起功能障碍的重要原因。罂粟碱诱导的多普勒超声检查和海绵体造影在准确评估和全面护理这些患者方面显示出前景。
