尿道粘膜发生损伤或炎症病变时,因其渗透性增加,尿道内容物可随着尿道内压力的增加而透过病变粘膜,进入海绵体和静脉血流内。此种现象可在尿道造影时获得证实,并可用来阐明尿道热和粘膜麻醉时发生中毒的机制。本文根据实际病例,将其临床意义分别讨论如下:一、尿道粘膜渗透现象在尿道造影时的临床意义尿道造影时发现的尿道粘膜渗透现象,作者们曾遇见3例: Urethral mucosa injury or inflammatory lesions, because of its increased permeability, urethral contents can increase with the urethral pressure through the lesion mucosa, into the cavernous and venous blood flow. This phenomenon can be confirmed when the urethra, and can be used to clarify the urethra and mucosal anesthesia occurs when the mechanism of poisoning. This article based on the actual case, the clinical significance of the discussion are as follows: First, the clinical significance of the phenomenon of urethral mucosal infiltration during urethroplasty urethral mucosa found during urethral infiltration, the authors have met three cases:
