The diagnosis of venous impotence is actually reached through cavernometry and cavernography. These procedures are somewhat painful, invasive, time consuming and not always free from side effects. Anatomo-physiological studies have assessed connections between periprostatic (Santorini's) plexus and deep venous drainage of the penis. Moreover, dilated periprostatic plexus is a common ultrasound finding in the phlogistic pathology of the prostate and it is often the cause of temporary functional impotence. 20 Patients suffering from venous impotence, previously assessed by flow/pressure studies, underwent real time transrectal scan (Kretz Combison 330 equipped with 7.5 MHertz multiplanar probe) before and after Prostaglandins E1 (PGE1) (Prostin VR-Upjohn) induced erection recorded by computerised rigidometer (RigiScan-Dacomed). Dilated periprostatic venous plexus associated with tumescence or unstable valid erection ("tooth-saw-trace") was considered diagnostic for venogenic impotence. Real time ultrasound evaluation after PGE1 induced erection is to be considered a reliable method in the qualitative assessment of venogenic impotence. The procedure allows, moreover, a more accurate urologic assessment and is also useful in the early detection of various prostatic disease which are, like erection disorders, often age-related. Customary diagnostic procedures (cavernometry and caverography) may represent a second-line or pre-surgical assessment policy.
静脉性阳痿的诊断实际上是通过海绵体测压法和海绵体造影术来实现的。这些检查方法会带来一定痛苦，具有侵入性，耗时较长，且并非总是没有副作用。解剖生理学研究已经评估了前列腺周围（Santorini）丛与阴茎深部静脉引流之间的联系。此外，前列腺周围丛扩张是前列腺炎症性病变中常见的超声表现，且常常是导致暂时性功能性阳痿的原因。20例患有静脉性阳痿的患者，此前已通过血流/压力研究进行了评估，在使用前列腺素E1（PGE1）（普适泰VR-Upjohn）诱导勃起前后，通过配备7.5兆赫兹多平面探头的实时经直肠扫描（Kretz Combison 330）进行检查，并由计算机化硬度计（RigiScan-Dacomed）记录勃起情况。与肿胀或不稳定有效勃起（“锯齿状痕迹”）相关的前列腺周围静脉丛扩张被视为静脉性阳痿的诊断依据。PGE1诱导勃起后的实时超声评估应被视为定性评估静脉性阳痿的可靠方法。此外，该检查方法还能进行更准确的泌尿外科评估，并且在早期发现各种前列腺疾病方面也很有用，这些疾病与勃起功能障碍一样，通常与年龄相关。传统的诊断方法（海绵体测压法和海绵体造影术）可能代表二线或术前评估策略。
