On the basis of a case of thoracic ectopic kidney, discovered following trauma and diagnosed at laparotomy (since it was confused with rupture of the left diaphragm) the authors review certain data concerning this rare malformation (150 published cases). --The site of origin of the renal artery may be used to distinguish on the one hand between true intra renal ectopic kidney with the renal artery arising from the aorta and secondly trans-diaphragmatic herniation of a kidney with a kidney with a normal vascular pedicle through a hernia, most often congenital, and equally often right as left. --Clinically, at the time of a routine examination or following trauma, chest X-ray reveals an opacity at the base of the thorax, the low and posterior topography of which is suggestive of the diagnosis and and IVP is then indicated. In the absence of violent trauma, the diagnosis of traumatic hernia is eliminated. The distinction between true ectopic kidney and congenital trans-diaphragmatic hernia becomes a false problem since there is no need for treatment in either case.
基于一例胸部异位肾病例，该病例在创伤后被发现并在剖腹手术时确诊（因最初被误诊为左膈肌破裂），作者回顾了有关这种罕见畸形（已发表150例病例）的某些资料。——肾动脉的起源部位可用于区分：一方面是真正的肾内异位肾，其肾动脉起源于主动脉；另一方面是肾脏经疝（最常见为先天性，左右侧发生率相同）形成的经膈肌疝，这种情况下肾脏血管蒂正常。——临床上，在常规检查时或创伤后，胸部X线显示胸腔底部有不透明阴影，其位置偏低且靠后提示可能为此病，此时应进行静脉肾盂造影（IVP）检查。若无暴力创伤，则可排除创伤性疝的诊断。真正的异位肾与先天性经膈肌疝之间的鉴别已成为一个伪问题，因为无论哪种情况都无需治疗。
