A kidney cut to show several cystic spaces, some of which contain pus; in the upper space, where the
origin of the calyces can be seen, there is pus and blood clot. The outer surface of the kidney shows
foetal lobulation and an occasional scar.
This woman had a stone removed from this kidney in April 1977 and, following this, the
kidney failed to function. She had had dysuria since the stone was removed, and some pain in the
back and in the left iliac fossa. The kidney was therefore removed.
