目的观察阴茎背神经选择性分支切断术治疗原发性早泄(PPE)的临床疗效,及在勃起状态下手术前后的阴茎震动感觉阈值变化。方法对116例PPE实施阴茎背神经选择性切断术,观察手术治疗前后的的平均阴道内射精潜伏期、患者及配偶性交满意度评分。使用生物振动测试仪测定阴茎勃起状态下的振动感觉阈,测定部位为示指、阴茎头、阴茎干的皮肤。结果 116例PPE术后射精潜伏期延长显效为78例,好转27例,总有效率为90.51%,无效11例。患者及其配偶的性交满意度评分在术后较术前均显著提高(P<0.01)。阴茎勃状态下,PPE手术治疗后的阴茎头、阴茎干振动感觉阈值显著高于术前(P<0.01)。结论阴茎背神经选择性分支切断术治疗PPE的疗效确切。
Objective To observe the clinical efficacy of selective dorsal branch of penis dorsal nerve transection (DPE) in the treatment of primary premature ejaculation (PPE) and the threshold of penile sensation before and after erection. Methods One hundred and sixty-six patients with PPE underwent selective dorsal penile nerve transection. The mean intravaginal ejaculation latency before and after surgery was observed, and satisfaction scores of patients and their spouses were obtained. Vibrating sensory threshold was measured using a biological vibration tester under penile erection. The site of measurement was the index finger, penis head, and the skin of the penis. Results 116 cases of PPE postoperative ejaculation latency was significantly improved 78 cases, improved in 27 cases, the total effective rate was 90.51%, 11 cases were ineffective. The scores of sexual satisfaction of patients and their spouses were significantly increased after surgery (P <0.01). Penile penis state, penile head and penile vibration sensory threshold after PPE operation was significantly higher than preoperative (P <0.01). Conclusion The treatment of PPE by dorsal penile nerve denervation is effective.
