297 Risks of Delaying De-Obstruction of an Acutely Infected Obstructed Urinary Tract

Abstract Introduction We investigated patients with acute urinary tract obstruction in a DGH to ascertain which factors predispose CKD and mortality. Method Over five months there were 37 nephrostomy/stent cases, 18 female, 3 mortalities. Median age was 55.5 (18-93). Retrospective data used multiple regression analysis. Input variables included the intervention indication, admission Creatinine, Charlson Co-morbidity Index, delay. Output length of hospital stay, renal function 90-day Results Positive urine cultures (p = 0.035) co-morbidity 0.018) associated CKD. Nephrostomy 0.031) AKI post-procedure. Delay disobstruction < 0.01) delay-length 0.026) significantly longer stays. severity on 0.047) delay 0.045) increased risk mortality, positive blood 0.071) trending towards significance. Malignant neared significant association 0.08) mortality 0.075). Conclusions The presentation all contribute poorer outcomes admission. Co-morbid malignant had higher Therefore, those poor baseline, are we intervening inappropriately?
