The left kidney should be visualised deep to the spleen (Image 4). Obstruction of the view of the left kidney by large colon indicates nephrosplenic entrapment (Image 5), although it is recommended to pair these findings with per-rectum examination (Scharner et al. 2002). 1 Gastrosplenic Window – place the probe sequentially at the levels of the 10th- 15th intercostal spaces in the middle one third (dorsoventrally)on the left side of the abdomen.
