摘　　要：目的对骨盆骨折模型尿道行CT扫描,探讨耻骨联合分离和后尿道损伤的关系。方法于男性骨盆标本尿道内置入造影剂,制成开书型骨折模型,CT扫描测定尿道和骨盆壁的关系。结果耻骨联合分离6cm时,尿道前列腺、尖部与完整侧耻骨联合后缘的距离从(2.03±0.27)cm分离到(2.95±0.31)cm,伴有尿道向完整侧半骨盆移位。结论骨盆骨折尿道损伤多发生于前列腺尖部,骨折时尿道前列腺尖部、前列腺部及膜部均向尾侧和健侧移位。Objective To explore the mechanism and feature of urethral injury caused by separation of pubic symphysis by CT scanning after urethrography. Methods Different degrees of open- book pelvic fractures were made and a soft duct filled with CT contrast medium was inlayed into urethra, and scanned by CT. Accurate measurement was carried out from urethra to the hinder margin of pubic symphysis, ischiadic ramus and the nail. Results When the separation reached 6cm, the displacement was obvious to the tail in apex of prostate. Distance from apex of prostate to the hinder margin of pubic symphysis became （2.95 ± 0.31） cm from （2.03 ± 0.27） cm. Meanwhile, the urethra was displaced to the non - injured half pelvis in lateral direction. Conclusion Urethral injury occurs mainly in apex of prostate. Prostatic urethra and membranous urethra are displaced to the tail and the non- injured half pelvis with the pelvis fracture.
