目的:评估保留阴茎头手术治疗阴茎癌对勃起功能的影响。方法:回顾性分析31例行保留阴茎头手术治疗的阴茎鳞状细胞癌患者。所有患者术前、术后1个月及3个月采用国际勃起功能指数问卷调查评估勃起功能,并对数据进行统计学分析。结果:31例患者,术前勃起功能正常18人,轻度勃起功能障碍13人。总体患者术前与术后1个月相比,勃起功能评分无统计学差异(P=0.604),术后1个月与术后3个月相比无统计学差异(P=0.051),但术前与术后3个月相比差异有统计学意义[(24.61±1.38)vs(25.38±1.02),P=0.014],术后3个月勃起功能优于术前。术前勃起功能正常组术前、术后1个月、术后3个月勃起功能评分相比差异均无统计学意义(P>0.05);术前轻度勃起功能障碍组术前、术后1个月、术后3个月勃起功能评分相比差异均有统计学统计意义(P<0.05)。结论:保留阴茎头手术治疗阴茎癌可以维持并能改善部分患者的勃起功能。对勃起功能的维持主要体现在术前勃起功能正常患者,而对于术前轻度勃起功能障碍患者,手术可以改善勃起功能,并且这种改善效果在术后3个月时表现显著。
OBJECTIVE: To evaluate the effect of preserving penile head surgery on erectile function. Methods: Retrospective analysis of 31 patients with penile squamous cell carcinoma who underwent penis surgery. All patients were evaluated preoperatively, 1 month and 3 months postoperatively using the International Erectile Function Index Questionnaire to evaluate erectile function, and the data were analyzed statistically. Results: There were 31 patients with 18 normal erectile function and 13 mild erectile dysfunction. There was no significant difference in erectile function scores between preoperative and postoperative one month (P = 0.604). There was no significant difference in postoperative one month and three months after operation (P = 0.051) The difference between preoperative and postoperative 3 months was statistically significant [(24.61 ± 1.38) vs (25.38 ± 1.02), P = 0.014]. The erectile function at 3 months postoperatively was better than preoperative. There was no significant difference in erectile function scores between preoperative and postoperative 1 month and 3 months postoperatively in preoperative erectile dysfunction group (P> 0.05). Preoperative and postoperative preoperative erectile dysfunction group The scores of erectile function in one month and three months after operation were statistically significant (P <0.05). Conclusion: Preservation of the penis surgery for penile cancer can maintain and improve erectile function in some patients. The maintenance of erectile function is mainly manifested in patients with preoperative erectile dysfunction, and for patients with mild preoperative erectile dysfunction, surgery can improve erectile function, and this improvement in the 3 months after the performance was significant.
