The present criteria to diagnose a ruptured posterior urethra in cases of a fractured pelvis do not provide accurate information on the degree and site of the urethral injury. A method of retrograde urethrography in such patients is described and the results obtained in 15 cases are reported. On the basis of these results a new classification of membranous urethral rupture in cases of fractured pelvis is proposed: type 1--the prostate or urogenital diaphragm is dislocated but the membranous urethra is merely stretched and not severed, type 2--the membranous urethra is ruptured above the urogenital diaphragm at the apex of the prostate and type 3--the membranous urethra is ruptured above and below the urogenital diaphragm. The clinical significance of these lesions is discussed and a plea is made for the more widespread use of retrograde urethrography in patients with a suspected posterior urethral rupture.
目前用于诊断骨盆骨折病例中后尿道断裂的标准，无法提供关于尿道损伤程度和部位的准确信息。本文描述了对此类患者进行逆行尿道造影的方法，并报告了15例患者的造影结果。基于这些结果，提出了骨盆骨折病例中膜部尿道断裂的新分类：1型——前列腺或尿生殖膈脱位，但膜部尿道仅被拉伸而未断裂；2型——膜部尿道在前列腺尖部尿生殖膈上方断裂；3型——膜部尿道在尿生殖膈上方和下方均断裂。文中讨论了这些损伤的临床意义，并呼吁在疑似后尿道断裂的患者中更广泛地应用逆行尿道造影。
