Flank Pain

A 62-year-old man presented with right upper flank pain. Mild leukocytosis and fever was present. His BP was 152/97. He stated that he had had the same symptoms periodically through the years but never sought medical attention because “it always goes away.” However, he stated that this episode was worse and therefore he sought medical attention. X-ray disclosed a dilated renal pelvis and the presence of a large stone. An image from a similar case is shown below.

1. Klebsiella
