The aim of this study was to make clear differences of pathophysiology and living environment among dialyzed patients and non dialyzed patients with type 2 diabetic foot ulcer.
　Methods：The objectives of this study were outpatients with type 2 diabetes from May 2002 to November 2004. The patients were classified based on those have diabetes foot ulcer on dialysis as the case（Group 1）, those have diabetes foot ulcer without dialysis as the control matched sex and ages for the case（Group 2）. Data were collected from medical records and interviews.
　Results：During the 30 study months, 21 for the case and 31 for the control were examined. The pathophysiology of lower limb and the treatment days for the foot ulcer were significant difference among in the groups. We found sensory deficit in 83% of all patients, and recurrence at new location in 32 %. The half of the all patients could not perform self assessment of their own foot conditions and adequate foot care, although they needed walk assistant tools. It was suggested to prevent and manage of the diabetic foot ulcer that 1）periodical evaluation of ischemic foot and arterial sclerosis of dialyzed patients, 2）to enforce adequate evaluation of walk assistance tools and sensory deficit, 3）to teach the patients about self assessment of their foot conditions.
