In patients with complete disruption of the membranous urethra treated initially with placement of a suprapubic cystostomy, delayed synchronous retrograde and voiding cystourethrograms failed to demonstrate accurately the distance between the two urethral ends. Radiographic exposure obtained during synchronous instrumentation of the anterior and posterior urethra in the anesthetized patient was the most precise method of defining the extent of the urethral gap. Any surgical decision should be based on this type of investigation. In most cases of pelvic crush injuries, the severed membranous urethra probably remains attached in close proximity to the distal segment, thus directing the redescent of the prostate and bladder base in the presence of a contracting pelvic hematoma.
对于最初接受耻骨上膀胱造瘘术治疗的膜部尿道完全断裂患者，延迟同步逆行性膀胱尿道造影和排尿性膀胱尿道造影未能准确显示两个尿道断端之间的距离。在麻醉患者中对前后尿道进行同步器械操作时获得的X线曝光是确定尿道间隙范围的最精确方法。任何手术决策都应基于此类检查。在大多数骨盆挤压伤病例中，离断的膜部尿道可能仍与远侧段紧密相连，从而在盆腔血肿收缩时导致前列腺和膀胱底部下降。
