A cloacal malformation is a congenital malformation in which the urinary tract, gynecological system and distal rectum fail to separate and form a common channel with a single perineal opening. Precise anatomical information is required to plan surgery and predict prognosis for children with this abnormality. Conventional fluoroscopic studies provide limited information, primarily due to the overlap of structures and inability to make accurate measurements. Rotational fluoroscopy and 3-D reconstruction help clarify overlapping structures and allow for precise measurement of the common channel, thereby helping to predict the complexity of the surgical case as well as the long-term prognosis regarding bowel, bladder and sexual function.
先天性泄殖腔畸形是一种先天性畸形，其中尿路、妇科系统和远端直肠未能分离，并形成一个具有单一会阴开口的共同通道。对于患有这种异常的儿童，需要精确的解剖学信息来计划手术并预测预后。传统的荧光透视研究提供的信息有限，主要是由于结构重叠和无法进行准确测量。旋转荧光透视和 3-D 重建有助于澄清重叠结构，并允许对共同通道进行精确测量，从而有助于预测手术病例的复杂性以及与肠道、膀胱和性功能相关的长期预后。
