Serious infections in the urological field associated with diabetes mellitus: A report of four cases

We report the cases of four patients with serious infections which occurred as a complication of diabetes mellitus. The first case was an 82-year-old woman with acute focal bacterial nephritis. The second case was a 67-year-old man with a psoas-abscess which produced gas. The third case was a 90-year-old man with emphysematous cystitis and a renal cyst cystic abscess which produced gas. The fourth case was a 70-year-old woman with emphysematous pyelonephritis. Cases of serious infection in the urinary tract, retroperitoneal space or male genitals that are complicated by diabetes mellitus are expected to increase from now on, because of the increasing number of patients with diabetes mellitus. For the purpose of providing suitable early treatment, early diagnostic imaging such as CT imaging is very important.
