准确的尿路狭窄成像是术前分期和重建计划的关键。目前的金标准，逆行尿路造影术(RUG)，可以准确地诊断、分期和描绘尿道狭窄，仍然是治疗尿路狭窄疾病的基石。在复杂的情况下，地毯可以与排尿膀胱尿路造影(VCUG)相结合，以便更好地显示后尿路或复杂的牵张缺陷。通过膀胱镜逆行或顺行直接显示狭窄，可以提供关于狭窄的位置和外观的额外信息，以及在透视成像上的精确定位。超声尿路造影(SU)是一种有用的辅助手段，可以三维评估狭窄的长度和位置，也可以作为术中评估的有用工具，然而，它的使用仍然局限于二线设置。CT或磁共振尿路成像横断面成像可以提供解剖结构及其关系的额外三维信息，在复杂的临床场景中可以作为有用的辅助工具。
Accurate imaging of urethral strictures is critical for preoperative staging and planning of reconstruction. The current gold standard, retrograde urethrography (RUG), allows for accurate diagnosis, staging, and delineation of urethral strictures, and remains a cornerstone in the management of urethral stricture disease. In complex situations, the RUG can be combined with voiding cystourethrogram (VCUG) in order to better visualize the posterior urethra or complex distraction defects. Direct visualization of the stricture by cystoscopy, either retrograde or antegrade, can provide additional information as to the location and appearance of stricture, as well as precise location on fluoroscopic imaging. Sonourethrography (SU) is a useful adjunct to allow for three-dimensional assessment of stricture length and location, and can be a useful intraoperative assessment tool, however, its use remains limited to a second-line setting. Cross-sectional imaging in the form of computed tomography (CT) or magnetic resonance urethrography can provide additional three-dimensional information of anatomic structures and their relations, and can serve as a useful adjunct in complex clinical scenarios.
