[Risk Factors for Mortalityin Patients with Urosepsis]

Urosepsis is not uncommon and sometimes causes a critical condition including death. We retrospectivelyanaly zed the risk factors for mortalityin urosepsis. We treated 80 patients as urosepsis from 2010 to 2014 in our hospital. Five patients (6%) died within 30 days of hospitalization. The median age of the patients who died of urosepsis was 92 years (range, 83-95 years). The main causes of urosepsis were complicated pyelonephritis in 4 patients and emphysematous pyelonephritis in one. In the subgroup analysis of elderly patients over 75 years old, bad performance status and lower serum albumin were significantlyrelated to mortality(p ＝0.033, 0.046). The elderlypatients, especiallywith bad performance status and lower serum albumin, are more likelyto die.
