手术原理
生理性勃起时,血液经由阴茎动脉灌注进入两侧阴茎海绵体内,使其充血膨胀。海绵体外侧被坚韧的白膜包裹,同时压迫静脉阻滞血液流出,从而产生坚挺充盈的勃起。
对于重度难治性勃起功能障碍(ED)患者,在口服药物、体外冲击波或注射等保守治疗无效时,人工阴茎植入手术(Penile Prosthesis Implantation)是最终确实有效的终身治疗方案。手术将人工阴茎体植入阴茎海绵体腔内,取代病损海绵体,仍包覆在原有白膜内。术后阴茎可获得充足硬度以进行正常性生活,外观与触感逼真自然,且完整保留射精、性高潮及皮肤敏感度。
麻醉方式:双重局部麻醉
传统手术通常在椎管内半身麻醉或全身麻醉下完成。
本院采用创新双重局部麻醉技术,涵盖背神经近端阻滞、阴茎脚阻滞及基底浸润阻滞,仅在阴茎根部注射局部麻醉药物(图1)。手术全程患者意识清晰且无疼痛,可轻松操作手机或佩戴蓝牙耳机听音乐。

手术切口与住院说明
切口常位于龟头冠状沟下方、耻骨部或阴囊阴茎交界处,长度约3厘米。无需住院留观,属于门诊日间手术,术后即可自行步行离院回家休养。
手术步骤与装置类型
1. 半硬可折式人工阴茎:植入两支内含合金轴芯的医用硅胶体柱,术后约2个月恢复期后,即可手持向上扳起进行性生活(图2C、图3A),事后向下折弯贴合隐蔽(图2D、图3B)。机械耐用度高,无机械故障风险。


2. 三件充水式人工阴茎(三件套 IPP):由海绵体内充水圆柱体、阴囊调水泵与耻骨后储水囊三部分组成(图4)。捏挤阴囊内的液压泵即可使液体注入柱体膨胀充盈(图5A);按下释放阀液体流回储液囊,恢复自然疲软(图5B)。仿真度与生理体验好。


避免电刀止血 · 微创显微解剖保护
本院严格实行不使用电灼止血,采用细微缝线逐一结扎止血,避免高温对神经血管束产生热损伤,防止神经麻木与慢性疼痛。最大程度保留组织血供,提高抗感染能力,促进切口愈合。
手术预后与满意度
多中心临床随访显示,人工阴茎手术患者及其伴侣的满意度普遍超过 85%。糖尿病患者术前须将糖化血红蛋白控制在合适范围(HbA1c < 8%)以确保安全、减少感染风险。
| 假体类型 | 手术特点 | 优点与考量 |
|---|---|---|
| 半硬可折式 | 手术时间短,操作相对简明 | 优点: 构造坚固耐用,几乎无机械故障。 考量: 初期稍有硬物感,一般数周内逐渐适应。 |
| 三件充水式 | 手术精密,技术门槛高 | 优点: 勃起硬挺与疲软下垂切换自如,极为自然逼真。 考量: 构造精密,长期使用存在耗损维护可能。 |
