Intrathoracic kidney

Intrathoracic kidneys are rare, meaning that some or all of the kidneys pass through the diaphragm and enter the mediastinum. It is different from a diaphragmatic hernia in which the abdominal organs and kidneys enter the chest at the same time. The intrathoracic kidney is located behind the diaphragm, in the Bochdalek hole, where the diaphragm becomes thin, as if the membrane covers the protruding portion of the kidney, so the kidney is not in the free chest cavity. The inner chest kidney has completed the normal rotation process, and the kidney morphology and collection system are normal. Renal blood vessels and ureters leave the chest cavity through the Bochdalek hole. The ureter was stretched, but entered the bladder without ectopic, and the contralateral kidney was normal.
