Introduction: To assess the predictors for conservative management failure and long term outcomes after isolated blunt high grade renal trauma (HGRT).
Methods: A retrospective analysis of patients with isolated blunt HGRT (renal trauma grade ≥ IV) was conducted. Patients' demographics, clinical presentation, laboratory and radiological investigations, and different lines of treatment were retrieved. The primary outcome was to assess the predictors of conservative treatment failure (need for active bleeding control e.g.: transarterial angioembolization (TAE) and/or surgical exploration). The secondary outcome was to assess the renal parenchymal volume (RPV) changes post HGRT in correlation with the different lines of management using CT-measured RPV. The difference in RPV ≥ 5% at follow up was considered significant.
Results: The study included 63 patients, mean (SD) age was 35.1 (16.6) years. Conservative management was successful in 39 patients (62%), while the need for active bleeding control was required in 16 and 8 patients who underwent TAE and surgical exploration, respectively. Increased hematoma rim distance (HRD), laceration numbers > 3, parenchymal devascularization ≥ 25%, and presence of vascular contrast extravasation (VCE) were predictors for conservative treatment failure (P= 0.006, 0.02, 0.045 and 0.002, respectively). After a mean of 19 months follow up, patients were subclassified into 2 groups: patients with preserved RPV (28 patients) and patients with decreased RPV (29 patients). Renal parenchymal devascularization ≥ 25% was found a predictor for ipsilateral RPV decrease (P = 0.02).
Conclusion: Increased HRD, laceration numbers > 3, parenchymal devascularization ≥ 25%, and presence of VCE are findings that reflect the necessity for active bleeding interventions after isolated blunt HGRT. Parenchymal devascularization ≥ 25% is an independent factor for RPV deterioration. Neither the grade of renal trauma nor the type of treatment is a predictor for such deterioration.
