阴茎负压吸引治疗血管性勃起功能障碍42例疗效观察

目的：探讨真空负压吸引治疗男性血管性勃起功能障碍(ED)的有效性。方法选取2013年1月至2015年5月我院收治的42例血管性ED患者，其中17例动脉性，25例静脉性，均采用真空负压吸引治疗6个月，在治疗前后进行国际勃起功能指数(IIEF-5)评分，并通过彩色多普勒超声检测治疗前后阴茎海绵体动脉血流峰值速度(PSV)，舒张末期速度(EDV)、阻力指数(RI)。结果动脉性ED组经治疗后左右两侧PSV、RI及IIEF-5评分均较治疗前提高，差异均有统计学意义(P<0.05)，而左右两侧EDV与治疗前比较差异均无统计学意义(P>0.05)，治疗有效率及对性生活满意率均为64.7%(11/17)；静脉性ED组经治疗后左右两侧PSV与治疗前比较差异无统计学意义(P>0.05)，EDV较治疗前降低，差异有统计学意义(P<0.05)，RI及IIEF-5评分较治疗前提高，差异有统计学意义(P<0.05)，治疗有效率及对性生活满意率分别为52%(13/25)和48%(12/25)；此外，治疗后动脉性ED组患者的IIEF-5评分为（17.47±3.97）分，高于静脉性ED组的(14.35±3.98)分，差异有统计学意义(P<0.05)。结论阴茎真空负压吸引治疗血管性勃起功能障碍有效，其中治疗动脉性ED效果更好，患者对性生活的满意度更高。

Effect of vacuum therapy for vasculogenic erectile dysfunction:a report of 42 cases

Objective To study the efficiency of vacuum negative pressure aspiration for treating vascular male erectile dysfunction (ED). Methods Forty-two cases of vascular ED patients admitted to our hospital from Janu-ary 2013 to May 2015 were selected, of which 17 cases were artery (arterial ED group) and 25 cases were vein (venous ED group). All of them were treated for 6 months with vacuum negative pressure aspiration, and the likely improvements of erectile dysfunction (ED) before and after the treatment were measured by the International Index of Erectile Function (IIEF-5). Moreover, peak systolic vebcity (PSV), end diastolic velocity (EDV), resistive index (RI) of corpus cavernosum artery were also inspected with color Doppler ultrasound before and after the treatment. Results The rating of left and right sides PSV, PI and IIEF-5 of arterial ED group was improved after treatment and the difference was of statistical sig-nificance (P<0.05). Compared with before treatment, there was no statistical significance for left and right sides EDV after treatment (P>0.05). Treatment efficiency as well as sexual satisfaction rate were both 64.7%(11/17). Compare with before treatment, there was no statistical significance for left and right sides PSV of venous ED group after treatment (P>0.05). EDV of venous ED group after treatment was significantly lower than before treatment (P<0.05);Compared with before treatment, the rating of RI and IIEF-5 was significantly improved (P<0.05);Treatment efficiency and sexual satisfaction rate were 52%(13/25) and 48%(12/25) respectively. Besides, the IIEF-5 of arterial ED group (17.47 ± 3.97) after treat-ment was significantly higher than that of venous ED group (14.35±3.98), P<0.05. Conclusion Vacuum negative pres-sure aspiration is an efficient method for treating vascular male erectile dysfunction, and the artery ED patients have higher satisfaction with the efficiency than the vein ED patients.
