Retrograde urethrography is a valuable diagnostic aid of lesions in the urethra. It, however, has inherent hazards in the form of urethrocavernous and urethrovascular reflux of contrast medium, particularly in the presence of inflammatory urethral stricture. A case of massive urethrocavernous and urethrovascular reflux is reported. The dangers of such systemic reflux of urethral contents, including pathogens and contrast material are highlighted. Observation of reflux during retrograde urethrography exposes the patient to bacteremia and sepsis, and this fact must not be overlooked by the radiologist and the clinician. Prompt admission of the patient with adequate prophylactic antibiotic cover is the rule in such situation.
逆行尿道造影是诊断尿道病变的一种重要辅助手段。然而，它存在造影剂尿道海绵体及尿道血管反流等固有风险，尤其是在存在炎性尿道狭窄的情况下。本文报告了一例大量尿道海绵体及尿道血管反流的病例。文中强调了尿道内容物（包括病原体和造影剂）这种全身反流的危险性。逆行尿道造影时对反流的观察会使患者面临菌血症和败血症的风险，放射科医生和临床医生绝不能忽视这一事实。在这种情况下，应遵循的原则是及时让患者入院并给予充分的预防性抗生素覆盖。
