超声诊断阴茎硬结症的价值

目的 探讨超声检查诊断阴茎硬结症（PD）的价值。方法 分析48例PD患者的超声特征，比较超声与临床触诊检出阴茎斑块数目的差异。结果 临床触诊检出阴茎斑块66个，超声检出80个，差异有统计学意义（Z=1.812 5，P<0.05）。超声检出的80个阴茎斑块中，48个（48/80，60.00%）呈中高回声，24个（24/80，30.00%）呈强回声，6个（6/80，7.50%）呈低回声，2个（2/80，2.50%）呈高回声伴条状强回声；4个斑块周边及5个斑块内部可检测到条状或点状血流信号，1个斑块内部及周边均探及条状血流信号。2例PD患者合并阴茎动脉功能不良，1例合并阴茎静脉闭塞功能障碍。结论 超声检出PD患者阴茎斑块明显优于触诊，且能评价PD合并勃起功能障碍患者的阴茎血管功能，为临床治疗PD及预后评估提供依据。

Value of ultrasound in diagnosis of Peyronie's disease

Objective To investigate the value of ultrasound in diagnosis of Peyronie''s disease (PD). Methods The ultrasonic characteristics of 48 PD patients were analyzed, and numbers of penile plaques detected with ultrasound and clinical palpation were compared. Results Totally 66 penile plaques were detected with clinical palpation and 80 plaques were detected with ultrasound (Z=1.812 5, P<0.05). Among 80 plaques detected with ultrasound, 48 (48/80, 60.00%) showed medium and high echo, 24 (24/80, 30.00%) showed strong echo, 6 (6/80, 7.50%) were hypoechoic, and 2 plaques (2/80, 2.50%) were hyperechoic accompanied calcification. Strip or punctate blood flow signals were found in the periphery of 4 plaques and the interior of 5 plaques, while strip blood flow signals were detected in the interior and periphery of 1 plaque. Two PD patients accompanied with penile arterial insufficiency, and 1 accompanied with penile veno-occlusive dysfunction. Conclusion Ultrasound is superior to palpation in the detection of penile plaque in PD patients,which can detect blood flow inside and around the plaques and evaluate penile vascular function in patients with erectile dysfunction, providing a basis for clinical treatment and prognostic evaluation of PD.
