Abdominal ultrasonographic evaluation of the urinary tract, adrenal glands, spleen, hepatobiliary, and gastrointestinal tract in juvenile eastern grey kangaroos (Macropus giganteus).

The purpose of this prospective and anatomic study was to describe the ultrasonographic anatomy of the kidneys, urinary bladder, adrenal glands, spleen, liver, gall bladder, and gastrointestinal tract in healthy juvenile eastern grey kangaroos (Macropus giganteus). As ultrasonographic descriptions are lacking in marsupial species, it was also conducted to develop a systematic approach for abdominal ultrasonographic evaluation in the kangaroo and to provide preliminary quantitative and qualitative references. Ten macropod cadavers (eight eastern grey kangaroos and two swamp wallabies (Wallabia bicolor)) were used for initial dissections and preliminary ultrasonographic examinations.
