Doppler ultrasonographic findings in patients after penile vein ligation surgery are described and compared to the results of cavernosometry and cavernosography. Peak systolic and end diastolic velocities were recorded for both cavernosal arteries at 5 min intervals after papaverine injection for a total of 30 min. Peak end diastolic flow rates were compared with cavernosometric and cavernosographic results at 0-10 min, 11-20 min, and 21-30 min. Cavernosography identified venous leakage in nine patients. The end diastolic velocities were greater than the 5 cm/s threshold level generally considered to be indicative of venous leakage in nine of the nine patients (100%) at 0-10 min, in eight of the nine (89%) at 11-20 min, and in nine of the nine (100%) at 21-30 min. Although peak end diastolic velocities at or near the 5 cm/s threshold could be found in patients both with and without recurrent venous leakage in the initial 10 min of the studies, only patients with recurrent venous leakage had diastolic velocities that exceeded the 5 cm/s level when measured 10 min or more after injection. Measurement of end diastolic velocities between 21 and 30 min after injection seemed to discriminate most effectively the patients with recurrent venous leakage from those without leakage in the postoperative population.
描述了阴茎静脉结扎术后患者的多普勒超声检查结果，并与海绵体测压和海绵体造影结果进行比较。注射罂粟碱后，每隔5分钟记录一次两侧海绵体动脉的收缩期峰值速度和舒张末期速度，共记录30分钟。将舒张末期峰值流速与0 - 10分钟、11 - 20分钟和21 - 30分钟时的海绵体测压和海绵体造影结果进行比较。海绵体造影发现9例患者存在静脉漏。在0 - 10分钟时，9例患者中有9例（100%）的舒张末期速度大于通常认为提示静脉漏的5 cm/s阈值水平；在11 - 20分钟时，9例中有8例（89%）；在21 - 30分钟时，9例中有9例（100%）。尽管在研究开始的10分钟内，有和没有复发性静脉漏的患者都可能出现接近或达到5 cm/s阈值的舒张末期峰值速度，但只有复发性静脉漏的患者在注射10分钟或更长时间后测量时舒张速度超过5 cm/s水平。注射后21至30分钟之间舒张末期速度的测量似乎最有效地鉴别了术后人群中有无复发性静脉漏的患者。
