Translations:Niere (Ren)/9/en

View from ventral: The kidneys lie retroperitoneally under the diaphragm. They are therefore passively moved with the respiration. In severe diseases such as metastatic tumours, this can lead to the disappearance of the fat capsule (capsula adiposa), in which the kidney is usually firmly integrated, and to the lowering of the kidneys. Vessels and the ureter can be trapped and disturbances in renal perfusion can be caused.
