Predictive indications of operation and mortality following renal trauma

This study is a review of our experiences related to managing patients with renal injuries and identifying the predictive indicators of surgery and mortality.

A retrospective review study was performed in our university hospital. Patients with renal injuries were enrolled. Data comparisons were performed between four patient groups (operation vs. nonoperation groups and mortality vs. survival groups, respectively).

Seventy-three patients were enrolled in this study, 55 of whom (75.34%) were male. Nine patients (12.33%) were severely injured (Injury severity score (ISS) ≥ 16), and nine (12.33%) had high renal injury scores (Renal injury scale (RIS) ≥ 4). Seven patients (9.59%) had received operations, and four (5.48%) died of hemorrhagic shock and multiple organ failure. After performing multivariate analysis, patients who received operations had significantly higher ISS (≥16) and RIS (≥4) scores compared with patients who did not undergo operations. ISS ≥ 16 and Glasgow coma scale (GCS) < 8 were significantly correlated with mortality.

In conclusion, ISS ≥ 16 and RIS ≥ 4 are predictive factors for necessitating an operation, and higher injury severity (ISS ≥ 16) and lower consciousness level (GCS < 8) scores are significantly associated with mortality after renal trauma.
