骨盆骨折合并后尿道损伤后阳萎发生机理的临床研究

为探讨骨盆骨折后尿道损伤后发生阳萎的机理、收集５１例骨盆骨折、后尿道损伤后患者的资料，对其性功能状况进行随访，并对１０例阳萎患者进行了有关阴茎勃起功能的检查。结果表明：伤后阳萎是初期损伤和（或）手术损伤所造成的阴茎神经、动脉损伤所致。由于解剖上的原因，单纯早期损伤所致阳萎多为神经性阳萎，而手术损伤多为动脉性阳萎。此外，损伤程度、伤时年龄及伤后时间等因素与阳萎的发病也有一定的关系。

Pathogenesis of impotence following pelvic fracture with posterior urethral injury

patients suffered from pelvic fracture with posterior urethral injury were reviewed and their sexual function has been followed up. There were 16 impotent cases and the erectile capability has been checked in 10 of the 16.The result demonstrated that post-traumatic impotence was usually a consequence of injury to the nerve and artery supplying the penis. The majority of impotence caused by the initial trauma was neurogenic while that caused by the operative procedures was arterial.It was also revealed that the incidence of impotence was correlated with the severity of pelvic fracture, the age of the patient and the duration of follow up.
