August 2008, showed stag horn calculus with branches in upper, middle and lower calyces. (Figure 3) On 22 August 2008, left extended pyelolithotomy was carried out under inhalational anaesthesia. Anaesthesia was started at 0845 hours.
CT of kidneys, performed on 09 September 2008 (arterial phase) showed an area of non-enhancement in posterior cortex (middle third) of left kidney (arrow).

In the portal venous phase of the scan, there were multiple areas of non-enhancing cortex posteriorly and in the upper pole of left kidney (Figures 4 and 5), suggestive of focal infarction.
CT of kidneys, performed on 09 September 2008 (arterial phase), showed non-perfusion in posterior cortex of left kidney (arrow); left ureteric stent in place; marked hydronephrosis of right kidney.

Mild to moderate left hydronephrosis was present. (Figure 7) Calculi were seen in left kidney.
Axial MR of kidneys (Arterial phase) performed on 18 November 2008, shows area of non-perfusion in posterior cortex, mid-pole of left kidney (arrow).

There was some thinning of the posterior cortex of the left kidney and on the post contrast dynamic scans, there was an area measuring 2 cm x 3 cm that was not perfused in the middle third posterior cortex consistent with infarction at this site (Figures 8 and 9); no other abnormality was noted.
Another section of the axial MR of kidneys (Arterial phase) performed on 18 November 2008 shows non-perfusion in posterior cortex, mid-pole of left kidney (arrow).
