Severe blunt renal trauma: a 7-year retrospective review from a provincial trauma centre.
Bibliographic record
Abstract
BACKGROUND: Renal trauma is reported in 3% of trauma patients. The majority (>90%) are due to blunt mechanisms of injury. Minor renal injuries pose few management difficulties and the majority are managed expectantly. More serious injuries are potentially life threatening and have been historically managed by operative intervention with repair of the injured kidney when possible. More recently, there has been a trend towards non-operative management of all solid intra-abdominal organ injury including renal trauma. The purpose of this study was to review a 7-year experience in renal trauma at a provincial trauma centre and to define management practices along with patient and organ outcomes in severe renal injury. METHODS: The BC Trauma Registry was reviewed for all admissions from January 1, 1992 to December 31, 1998 to identify patients with renal injury. Patient charts were reviewed to determine sex, age, mechanism of injury, vitals, imaging, associated injuries, and management and outcomes. Renal injuries were graded according to the American Association for the Surgery of Trauma Grading System. RESULTS: During the study period 16 250 consecutive trauma cases were seen at Vancouver General Hospital. Of these cases, 227 (1.4%) patients sustained renal injuries: blunt in 93.4% and penetrating in 6.6%. Among patients with blunt renal trauma, 18.3% were grade III, IV, or V injuries. In this population, nearly 80% had associated trauma and also 80% had gross hematuria. Management was conservative in 87.5% of grade III and 77.7% of grade IV; however, 90.9% of grade V injuries went immediately to the OR. Nephrectomy rates were: 12.5% (III), 16.6% (IV), and 90.9% (V) with an overall exploration rate of 7.1% for all blunt renal trauma. Blunt renal trauma patients experienced few genitourinary complications. Overall, 3 patients of 40 with grade III, IV or V injuries died due to cardiac arrest in the emergency room. CONCLUSIONS: Blunt renal trauma managed conservatively is associated with few complications in the hemodynamically stable patient. Grade V injuries still result in a nephrectomy rate of 90.9% with hemodynamic instability the indication in 100% of patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
