Maybe some kind of neurogenic tumor.

可能是某种神经源性肿瘤。

后天的包括1. 神经源性上睑下垂基本上是因为有神经支配缺陷，由于供应的神经不起作，就不能正常工作。

Yet another cause is a flaccid neurogenic bladder, when the bladder is unable to contract to release urine out of the body even when a person is consciously trying to release the urine.

还有个病因是松弛型神经源性膀胱，此时膀胱无法收缩以释放尿液排出体外，即便是患者有意地力排尿。
