The occurrence of non-function in one half of a horseshoe kidney resulting from hydronephrosis can, if unrecognized, create a serious surgical as well as medical problem. The anterior position of the ureter in relation to the isthmus, as well as strictures and accessory vessels increase the incidence of hydronephrosis, which if severe enough, can go on to non-function. The key diagnostic factor is the observation of the visualised side, which shows the characteristic malrotation of the calyces and the deviation of the long axis of the kidneys; these are associated with a mass effect on the obstructed side, with or without a 'crescent' sign. Five cases of this unusual occurrence are presented.
马蹄肾一半因肾积水而出现功能丧失，如果未被识别，会造成严重的外科及内科问题。输尿管相对于峡部的前方位置，以及狭窄和副血管会增加肾积水的发生率，若肾积水足够严重，可发展为功能丧失。关键的诊断因素是观察显影侧，其显示出肾盏特征性的旋转不良以及肾脏长轴的偏移；这些与梗阻侧的肿块效应相关，有或无“新月”征。本文报告了5例这种不寻常情况。
