We determined the risk factors for penile prosthesis infections.
The records of 156 men undergoing 167 procedures for insertion of a penile prosthesis were reviewed. The device was implanted during a primary uncomplicated procedure in 114 cases. Simultaneous penile reconstruction was performed in 23 cases. A malfunctioning penile prosthesis was replaced or repaired immediately following removal in 30 cases. Minimum followup was 1 year.
The infection rate was 1.8% after insertion of a penile prosthesis in 114 men without previous penile surgery compared to 21.7% for procedures requiring reconstruction of the corpora, which was significantly different (p < 0.01). The infection rate after revision of a penile prosthesis was 13.3%, which was significantly greater than that following primary uncomplicated implantation (p < 0.05) but not different from that for patients requiring reconstruction (p = 0.5). There was no difference in patient age, etiology of impotence or associated medical disorders among the 3 groups. Operative time was significantly longer for patients requiring penile reconstruction than for the other 2 groups (p < 0.01).
The risk of infection is significantly greater when penile reconstruction is required, and appears to be related to increased duration of surgery. The increased risk of infection associated with revision of a penile prosthesis cannot be explained by patient characteristics or operative time.
我们确定了阴茎假体感染的危险因素。
回顾了156名男性接受167次阴茎假体植入手术的记录。114例患者在初次无并发症手术期间植入假体。23例患者同时进行了阴茎重建。30例患者在取出故障阴茎假体后立即进行了更换或修复。最短随访时间为1年。
114例既往无阴茎手术史的男性在植入阴茎假体后的感染率为1.8%，而需要阴茎海绵体重建的手术感染率为21.7%，两者差异显著（p < 0.01）。阴茎假体翻修后的感染率为13.3%，显著高于初次无并发症植入后的感染率（p < 0.05），但与需要重建的患者的感染率无差异（p = 0.5）。三组患者的年龄、阳痿病因或相关内科疾病无差异。需要阴茎重建的患者的手术时间明显长于其他两组（p < 0.01）。
需要阴茎重建时感染风险显著更高，且似乎与手术时间延长有关。阴茎假体翻修相关的感染风险增加无法用患者特征或手术时间来解释。
