【摘要】 对98例男性进行阴茎背神经传导速度测定。19名具有正常性功能的健康成年男子(Ⅰ组)阴茎背神经传导速度均值为20.05±1.95m/s。11名心理性阳萎患者(Ⅱ组)及4名经会阴前列腺切除术后仍具有性功能者(Ⅵb组),阴茎背神经传导速度均值分别为18.64±3.31及17.0±2.92m/s,与正常组无显著差别。5名具有糖尿病史的阳萎患者(Ⅲ组)、11名外伤性阳萎患者(Ⅳ组)及6名经会阴前列腺如切除术后发生阳萎患者(Ⅵa组)阴茎背神经传导速度均值分别为11.0±5.02、10.09±3.94及9.0±2.65m/s,均显著低于正常组。异常率分别为80％、100％及100％。而42名病因未定的阳萎患者(Ⅴ组)阴茎背神经传导速度均值为11.71±4.13m/s,亦显著低于正常组。异常率亦高达83.3％。结果表明,有可能利用阴茎背神经传导速度测定来评价勃起的周围神经病变。更多还原

【Abstract】 Conduction velocity of dorsal penile nerve was measured in 98 males. The mean velocity was 20.05±1.95m/s in 19 healthy adult males (group Ⅰ), 18.64±331 and 17.0±2.92m/s in 11 patients with psychogenic impotence(group Ⅱ)and 4 patients with normal sexual function after transperineal prostatectomy(group Ⅵb)separately. No significant difference was observed between group Ⅰ and group Ⅱ, Ⅵb. The mean velocity was 11.0±5.02, 10.09±3.94, 9.0±2.65 and 11.71±4.31m/s respectively in 5 patients with diabetic impotence(group Ⅲ), 11 patients with traumatic impotence (groupⅣ), 6 patients with impotence after transperineal prostatectomy (group Ⅵa) and 42 patients with impotence of undefined pathogeny (group Ⅴ). Their velocity were significantly lower than group Ⅰ. The results showed that the peripheral neuropathy of erection can be assessed by measuring the conduction velocity in the dorsal nerve of penis.更多还原
