Crossed unfused ectopia constitutes a very rare variant of ectopic kidneys, with an approximate incidence of 1 : 75000. We hereby describe a rare case of an incidental finding of crossed unfused ectopic kidneys, in a 45-year-old gentleman incidentally found to have a bladder lesion. The unique blood supply of his kidneys has also been described. The present case also highlights the different subtypes of renal ectopia, the different embryological hypotheses behind their presentation, and the various systematic anomalies, associated with them. Variations in vasculature of ectopic kidneys have been only described in case reports and are crucial to recognize in case any further intervention is needed.
交叉未融合异位肾是一种非常罕见的异位肾变体，发病率约为1:75000。我们在此描述一例罕见病例，一名45岁男性偶然发现膀胱病变，同时意外发现交叉未融合异位肾。文中还描述了其独特的肾脏血液供应情况。本病例还突出了肾异位的不同亚型、其表现背后不同的胚胎学假说以及与之相关的各种系统性异常。异位肾血管的变异仅在病例报告中有描述，在需要进一步干预的情况下，识别这些变异至关重要。
