Pathologies of the male urethra are mostly obstructive in nature and require imaging to delineate the lesion type, site, extent and associated abnormality of the urinary bladder. Contrast urethrography (CU) is the gold standard investigation for urethral assessment but has many limitations. Cross-sectional imaging is infrequently used for the evaluation of the urethra but has been gaining importance recently. Multidetector computed tomographic urethrography (MDCTU) has the capability of evaluating the entire length of a male urethra in a single setting and overcomes many technical and patient limitations of CU. Being a novel technique, most radiologists are not familiar with MDCTU and the imaging spectrum of various urethral and bladder pathologies. This pictorial review attempts to present the imaging appearance of the normal male urethra and spectrum of pathological findings, with highlights on its advantages over the CU technique.
男性尿道疾病大多本质上属于梗阻性疾病，需要影像学检查来明确病变类型、部位、范围以及膀胱的相关异常情况。尿道造影（CU）是尿道评估的金标准检查方法，但存在诸多局限性。横断面成像很少用于尿道评估，但近年来其重要性日益凸显。多排螺旋计算机断层扫描尿道造影（MDCTU）能够在一次检查中评估男性尿道的全长，克服了CU的许多技术和患者方面的局限性。作为一项新技术，大多数放射科医生并不熟悉MDCTU以及各种尿道和膀胱疾病的影像学表现。本图文综述旨在展示正常男性尿道的影像学表现及病理结果谱，并重点介绍其相对于CU技术的优势。
