摘　　要：目的:探讨阴茎双功能多普勒超声(penile duplex doppler ultrasound,PDDU)新指标海绵体动脉管径舒缩比值(diastolic contraction ratio,DCR)在动脉型阴茎勃起功能障碍(erectile dysfunction,ED)分型诊断中的价值。方法:将2018年7月—2021年12月来我院行PDDU检查并经阴茎海绵体动脉或静脉造影确诊分型的ED患者,分为动脉型组(32例)、静脉型组(25例)和非血管性组(25例)。注射药物后在阴茎达到最大硬度时测量双侧阴茎海绵体动脉收缩期管径(a)、舒张期管径(b)、b/a(DCR)和收缩期峰速(PSV)、舒张末期峰速(EDV)、阻力指数(RI)等参数,探讨各组DCR差异性及DCR在动脉型ED中的诊断界值及准确率。结果:应用PDDU传统标准正确诊断动脉型ED 27例和静脉型ED 21例,血管性ED分型诊断的灵敏度、特异度和准确率分别为77.1%、89.4%和84.4%。动脉型组DCR值显著低于静脉型组和非血管型组(均P<0.05),而静脉型组与非血管型组间DCR值差异无统计学意义(P>0.05)。DCR值与PSV呈正相关(r=0.51,P<0.05)。将DCR≤1.11作为诊断阴茎海绵体动脉功能不良的标准时,诊断灵敏度、特异度分别为88.0%和87.5%(AUC=0.934),与传统PDDU诊断标准比较,灵敏度更高(P<0.05),特异度无明显差异(P>0.05)。结论:DCR可作为ED患者PDDU分型诊断的新参数,DCR≤1.1作为动脉型ED的诊断标准,其诊断准确率高于PDDU诊断。Objective To investigate the value of the new index of penile duplex doppler ultrasound(PDDU),cavernous artery diameter diastolic contraction ratio(DCR),in the diagnosis of arterial erectile dysfunction(ED).Methods ED patients who came to our hospital from July 2018 to December 2021 for PDDU examination and were confirmed by penile cavernous artery or venography were divided into arterial group(n=32),venous group(n=25)and non-vascular group(n=25).Systolic tube diameter(A),diastolic tube diameter(B),B/A(DCR),systolic peak velocity(PSV),end diastolic peak velocity(EDV),resistance index(RI)and other parameters of bilateral penile cavernous artery were measured when the penis reached the maximum hardness after injection.The differences of DCR in each group and the diagnostic cutoff value and accuracy of DCR in arterial ED were investigated.Results Twenty-seven cases of arterial ED and 21 cases of venous ED were correctly diagnosed by PDDU.The sensitivity,specificity and accuracy of vascular ED were 77.1%,89.4%and 84.4%,respectively.The DCR value of patients with arterial ED was significantly lower than that of the venous group and the non-vascular group(P<0.05),but there was no statistical significance in the DCR value between the venous group and the non-vascular group(P>0.05).DCR value was positively correlated with PSV(r=0.51,P<0.05).When DCR≤1.11 was used as the standard for diagnosis of penile cavernous artery dysfunction,the sensitivity and specificity were 88.0%and 87.5%(AUC=0.934).Compared with the traditional diagnostic criteria of PDDU,the sensitivity was higher(P<0.05),and the specificity was not significantly different(P>0.05).Conclusion DCR can be used as a new parameter for the classification and diagnosis of PDDU in ED patients.DCR≤1.11 is a diagnostic criterion for arterial ED,and its diagnostic accuracy is higher than that of PDDU.
