We investigated 95 patients referred for erectile dysfunction by penile blood pressure measurement, the intracavernous papaverine test and Doppler investigation of the penile arteries. Furthermore, penile cutaneous perception threshold, bulbocavernosus reflex latency and somatosensory cortical evoked potentials of the pudendal nerve were measured. In selected cases cavernosometry, cavernosography and corpus cavernosum electromyography were performed. Doppler investigation of the cavernous arteries after papaverine injection was more reliable than penile blood pressure measurement in the diagnosis of arteriogenic erectile dysfunction. Decreased sensibility of the penis may be the sole factor responsible for inability to sustain an erection. Erectile dysfunction may be provoked by impaired function of the pudendal nerve. Penile cutaneous perception threshold measurement and corpus cavernosum electromyography are mandatory in the evaluation of neurogenic etiology. Cavernosometry and cavernosography are reliable methods in the determination of abnormal drainage from the corpus cavernosum.
我们通过阴茎血压测量、海绵体内注射罂粟碱试验以及阴茎动脉多普勒检查，对95例因勃起功能障碍前来就诊的患者进行了研究。此外，还测量了阴茎皮肤感觉阈值、球海绵体反射潜伏期以及阴部神经的体感皮质诱发电位。在部分病例中，进行了海绵体测压、海绵体造影以及海绵体肌电图检查。注射罂粟碱后对海绵体动脉的多普勒检查在诊断动脉源性勃起功能障碍方面比阴茎血压测量更为可靠。阴茎感觉减退可能是无法维持勃起的唯一原因。勃起功能障碍可能由阴部神经功能受损引发。在评估神经源性病因时，阴茎皮肤感觉阈值测量和海绵体肌电图检查必不可少。海绵体测压和海绵体造影是确定海绵体异常引流的可靠方法。
