To compare pulsed duplex ultrasound and cavernometry in the aetiological diagnosis of veno-occlusive erectile dysfunction.
Between September 1995 and January 2005, 81 patients with a mean age of 48.45 +/- 12.35 years consulting for erectile dysfunction were investigated by cavernometry and pulsed duplex ultrasound before and after sensitization by intracavernous injection of 10 microg/ml of prostaglandin. The results of these two examinations were compared by the kappa concordance test.
According to pulsed duplex ultrasound, 54 patients presented veno-occlusive incompetence. According to cavernometry, 56 patients presented veno-occlusive incompetence. The concordance between the results of the two examinations was only moderate (kappa = 0.52, p < 0.0001, 95% CI: 0.5886-0.7967).
Duplex ultrasound is a first-line examination in a case of suspected organic erectile dysfunction due to a vascular cause. However, due to the limited concordance for the aetiological diagnosis of veno-occlusive erectile dysfunction between duplex ultrasound and cavernometry, cavernometry is still indicated in highly selected cases such as preoperative work-up.
比较脉冲双功能超声和海绵体测压法在静脉性勃起功能障碍病因诊断中的应用。
1995年9月至2005年1月期间，对81例平均年龄为48.45±12.35岁的勃起功能障碍患者在海绵体内注射10微克/毫升前列腺素致敏前后，采用海绵体测压法和脉冲双功能超声进行检查。通过kappa一致性检验比较这两种检查的结果。
根据脉冲双功能超声检查，54例患者存在静脉闭合功能不全。根据海绵体测压法检查，56例患者存在静脉闭合功能不全。两种检查结果之间的一致性仅为中等程度（kappa = 0.52，p < 0.0001，95%可信区间：0.5886 - 0.7967）。
对于疑似因血管原因导致的器质性勃起功能障碍病例，双功能超声是一线检查方法。然而，由于双功能超声和海绵体测压法在静脉性勃起功能障碍病因诊断方面的一致性有限，在诸如术前评估等高度特定的病例中，仍需进行海绵体测压法检查。
