Figure 1.
Figure 1. This CT image obtained right after the lithotripsy attempt shows a deformed right kidney together with a 3 mm opacity in the near vicinity of the duodenum (arrow), which was mistaken for extravasated oral contrast from the duodenum.
Figure 2.
Figure 2. In this CT image, the tract of the nelaton catheter which was used during the procedure may be seen clearly (black arrow). The white arrow points to the displaced calculus which was originally thought to represent extravasated oral contrast from the duodenum.
Figure 3.
Figure 3. The nelaton catheter, its tract through the kidney and the calculus, can all be seen in a demonstrative fashion in this CT scan.
