This study compares the findings of multidisciplinary evaluation to the three-night use of the PotenTest, a standardized stamp test for the evaluation of nocturnal penile tumescence, in 174 patients. An organic etiology was diagnosed in 54% of those evaluated. The PotenTest proved accurate as a screening device for organic disease. Among the 48 patients who did not break any of the stamps over the three nights, 40 were found to have an organic basis for their erectile failure, for a predictive value of 83%. Among the 68 patients who broke all of the stamps, 45 were found to have a psychogenic basis for their erectile failure, for a 66% predictive value. When one or two of the stamps were broken over the three nights, the predictive values as to the etiology of the erectile failure were considerably diminished and of no diagnostic value. Results for only one night of usage revealed that of the 73 patients who did not break the stamps, 56 (77%) were found to have an organic etiology. Of the 101 patients who broke the stamps on the first night, 63 (62%) were found to have a psychogenic etiology.
本研究将多学科评估结果与174例患者使用PotenTest（一种用于评估夜间阴茎勃起的标准化邮票试验）三晚的结果进行了比较。在接受评估的患者中，54%被诊断为器质性病因。PotenTest被证明是一种准确的器质性疾病筛查工具。在三晚内未弄破任何一张邮票的48例患者中，40例被发现勃起功能障碍有器质性基础，预测价值为83%。在三晚内弄破所有邮票的68例患者中，45例被发现勃起功能障碍有心理性基础，预测价值为66%。当在三晚内弄破一或两张邮票时，勃起功能障碍病因的预测价值显著降低且无诊断价值。仅一晚使用的结果显示，在未弄破邮票的73例患者中，56例（77%）被发现有器质性病因。在第一晚就弄破邮票的101例患者中，63例（62%）被发现有心理性病因。
