280 patients (aged 28 to 74 years, mean 57) with erectile failure (EF) underwent colour Doppler and duplex ultrasound imaging (CDI) following intracorporeal papaverine. After achieving a full, or nearly full, erection visual inspection and palpation revealed plaques and/or constriction or deformity of the penis in 55 (20%) cases. 10 (4%) were known to have Peyronie's plaques prior to referral. Of these 55 patients ultrasound showed focal echogenic plaques in 14 (25%) and diffuse thickening of the tunica albuginea in 41 (75%). CDI diagnosed arteriogenic EF in 20 (36%) of these patients, venous leak in 10 (18%), arterial and venous in two (4%) and a normal response in 23 (42%). In 11 (20%) patients (seven with arteriogenic EF and four with venous leak) the plaque was seen to be affecting vessels. These results indicate that abnormalities of the tunica albuginea are far more common in patients presenting with erectile failure than previously thought. We believe that the diffuse thickening is a form of Peyronie's which is only recognized after pharmacological induction of penile erection.
280例勃起功能障碍（EF）患者（年龄28至74岁，平均57岁）在阴茎海绵体内注射罂粟碱后接受了彩色多普勒和双功超声成像（CDI）检查。在达到完全或几乎完全勃起后，通过视诊和触诊发现55例（20%）患者存在阴茎硬结和/或阴茎狭窄或畸形。其中10例（4%）在转诊前已知患有佩罗尼氏硬结。在这55例患者中，超声检查显示14例（25%）有局灶性回声增强硬结，41例（75%）有白膜弥漫性增厚。CDI诊断这些患者中有20例（36%）为动脉性EF，10例（18%）为静脉漏，2例（4%）为动静脉混合性，23例（42%）反应正常。在11例（20%）患者中（7例动脉性EF和4例静脉漏），可见硬结累及血管。这些结果表明，白膜异常在勃起功能障碍患者中比以前认为的更为常见。我们认为，弥漫性增厚是佩罗尼氏病的一种形式，只有在药物诱导阴茎勃起后才能识别。
