To evaluate the changes in penile sensation by electrophysiological tests in patients who underwent radical prostatectomy (RP) and to demonstrate the role of dorsal penile nerve injury in postoperative erectile dysfunction.
Twenty-six volunteer patients who were eligible for RP were included in the study. Preoperative penile sensory electromyography and the International Index of Erectile Function-5 (IIEF-5) questionnaire were done for each patient. Erectile function assessment and electrophysiological evaluation of penile sensation were repeated at postoperative 3rd and 6th months.
Postoperative IIEF-5 scores and electromyography values were significantly lower than preoperative findings ( < 0.05). The IIEF-5 scores in the nerve sparing-RP (NS-RP) group were significantly higher than the non-nerve sparing-RP (NNS-RP) group in the postoperative period. Nerve conduction velocity values in the NS-RP group were also higher than the NNS-RP group at the postoperative 3rd and 6th months. However, these changes were not statistically significant ( > 0.05).
Patients who underwent RP have decreased penile sensation due to cavernous nerve damage and a possible dorsal penile nerve injury. The decrease of penile sensation may be associated with postoperative erectile dysfunction.
通过电生理测试评估接受根治性前列腺切除术（RP）患者的阴茎感觉变化，并证明阴茎背神经损伤在术后勃起功能障碍中的作用。
本研究纳入了26例符合RP条件的志愿者患者。对每位患者进行术前阴茎感觉肌电图检查和国际勃起功能指数-5（IIEF-5）问卷调查。在术后第3个月和第6个月重复进行勃起功能评估和阴茎感觉的电生理评估。
术后IIEF-5评分和肌电图值显著低于术前结果（<0.05）。在术后期间，保留神经的RP（NS-RP）组的IIEF-5评分显著高于非保留神经的RP（NNS-RP）组。在术后第3个月和第6个月，NS-RP组的神经传导速度值也高于NNS-RP组。然而，这些变化无统计学意义（>0.05）。
接受RP的患者由于海绵体神经损伤和可能的阴茎背神经损伤导致阴茎感觉减退。阴茎感觉减退可能与术后勃起功能障碍有关。
