Rupture of the posterior urethra is an uncommon but serious complication of anterior pelvic arch fracture. It is commonly believed that such injuries occur at the apex of the prostate and on urethrography result in extravasation of contrast material above the urogenital diaphragm. In 1977, Colapinto and McCallum proposed a different classification of such injuries. This paper presents experience in 18 proven cases of posterior urethral injury using this new classification. All patients were studied with retrograde urethrography before any attempt at urethral catheterization. The data support the contention that the traditional concept of posterior urethral injury is, in fact, unusual. Of 18 patients, 12 had complete or partial urethral injuries extending both above and below the urogenital diaphragm as demonstrated by urethrography. Only three of 18 patients had the classical injury, that is, extravasation into pelvic fascial planes limited inferiorly by an intact urogenital diaphragm.
后尿道断裂是骨盆前弓骨折一种少见但严重的并发症。人们普遍认为此类损伤发生在前列腺尖部，尿道造影显示造影剂在尿生殖膈上方外渗。1977年，科拉平托和麦卡勒姆提出了对此类损伤的不同分类。本文介绍了采用这种新分类法对18例确诊后尿道损伤病例的诊治经验。所有患者在尝试尿道插管前均接受了逆行尿道造影检查。数据支持这样一种观点，即传统的后尿道损伤概念实际上并不常见。在18例患者中，尿道造影显示12例存在完全或部分尿道损伤，损伤范围累及尿生殖膈上下。18例患者中只有3例出现典型损伤，即造影剂外渗至盆腔筋膜平面，下方受完整尿生殖膈限制。
