摘要
目的研究尿道外伤患者勃起功能障碍相关因素。方法对40例外伤所致尿道损伤患者采用IIEF-5量表、夜间阴茎勃起监测、血管活性药物注射下阴茎血流彩超检查并进行统计学分析。结果40例中,11例存在明显勃起障碍,3例有血管病变依据。所有患者受伤前后IIEF-5评分有显著性差异(P<0．05);耻骨联合有分离病人较不分离者在IIEF-5评分变化上幅度更大(P<0．05);两组患者在背深动脉收缩期流速上显示出统计学差异(P<0．05)。后尿道损伤患者在阴茎勃起长度变化、周径变化以及勃起持续时间上较前尿道损伤患者明显变小,且ED概率更高。背深静脉流速>5 cm／s患者的比率在两组人群中有显著性差异(P<0．05)。而静脉流速>5cm／s人群主要集中在30-40岁。结论尿道外伤患者发生勃起功能障碍与损伤部位尤其是耻骨联合分离与否、前后尿道损伤位置、神经受损受伤年龄相关,与心理因素也有一定关系。
Objective To investigate the correlation factors in patients suffered from the urethral trauma associated with erectile dysfunction. Methods 40 patients were tested with IIEF-5, NEVA system and PPUD. Results The IIEF-5 had the significant differentiation before and after trauma. The scores changing were larger in patients with pubic diasis than without pubic diasis. The same result also appeared in the changing of penile length and circumference between the posterior and anterior urethral trauma. The ratio about the velocity of penile dorsal vein〉 5cm/s had the significant differentiation, as well. Those suffered from the anterior urethral trauma had longer erectile duration than the posterior urethral injured patients. Posterior urethral injury was more likely to cause the erectile dysfunction than other. Differentiation were also found in the age between the velocity of penile dorsal vein〉5cm/s and 〈5cm/s. The percent whose velocity of penile dorsal vein〉5cm/s in the age of 30 to 40 is higher than others. Conclusion It is suggested that pubic diasis may be an important correlation factor in patients suffered from urethral trauma with erectile dysfunction. It also contributes to the injured places between anterior and posterior urethra and patients＇ ages. Psychogenic factor related to the erectile dysfunction too.
