American Association for the Surgery of @entity130 Scale for kidney XXXX predicts nephrectomy, dialysis, and death in @entity1 with @entity1913 and nephrectomy for penetrating @entity130 .

@entity1 @entity1913 @entity8 @entity130
BACKGROUND: Despite broad clinical use of the American Association of the Surgery of @entity130 (AAST) injury scale for kidney, it has only been found to predict the need for renal surgery in single institution series. We sought to validate this scheme for morbidity and mortality in a national cohort of @entity1 with @entity8 . METHODS: A retrospective cohort design was used to determine the association between increasing AAST scores and nephrectomy, dialysis, and mortality. The cohort included all @entity1 with a @entity8 in the National @entity130 Data Bank (NTDB) from 1994 and 2003. Univariate and multivariate prediction models were used for analysis of data. RESULTS: At the time of review, a total of 742,774 @entity1 records were registered in the NTDB. @entity8 occurred in 8465 @entity1 (1.2%). Increasing injury grade was associated with a greater nephrectomy (RR 12-127), dialysis (RR 1.3-4.7), and mortality (RR 1.3-1.9) rate for blunt @entity8 . For penetrating injury, nephrectomy was the only outcome that was associated with higher grades of @entity8 with a RR of 7.7 to 31 for grades III to V @entity130 . CONCLUSION: The AAST injury scale for kidney predicts for morbidity in blunt and penetrating @entity8 and for mortality in @entity1913 . Thus, we continue to support its use as a clinical and research tool.
