ABSTRACT
AIM OF THE STUDY: This study aimed to evaluate contemporary management strategies of pediatric renal trauma, focusing on the failure of conservative management and identifying its predictors.
METHODS: The National Trauma Database (2018-2021) was queried for pediatric patients (≤18 years) with renal injury, identified via AIS codes aligned with the AAST kidney injury grading system. Urological surgical procedures were identified via ICD-10 Procedure Codes. Patients were categorized into immediate surgical management (within 4 h), conservative management (no surgery), and failed conservative management (surgery after 4 h). Demographics, injury characteristics, and clinical data were analyzed using descriptive and univariate statistical analyses (Wilcoxon Rank Sum, Chi-square, Odds Ratios).
RESULTS: Of 7266 pediatric renal trauma patients, most were white (63.4 %) males (69.1 %), aged 12-18 (76.6 %), suffering from unintentional blunt trauma (86.9 %). Most (n = 6610, 95 %) received conservative management; however, 4.5 % (n = 298) failed. Common surgical interventions included ureteral stent placement (n = 200, 59 %), renal IR procedures (n = 44, 13 %), and nephrectomy (n = 33, 9.7 %). Nephrectomy rates at low AAST kidney injury grades (I-II) were higher with upfront surgical management (n = 7, 3.5 %) than with failed conservative management (n = 0). Predictors of failed conservative management included higher Injury Severity Score (ISS) and higher AAST kidney injury grades (III-V) (p < 0.05).
CONCLUSION: Conservative management failed in 4.5 % of paediatric renal trauma cases, associated with higher AAST kidney injury grade and ISS. Upfront surgical management correlated with a higher nephrectomy rate at lower injury grades compared to failed conservative management. Refinement of pediatric trauma protocols is needed for optimal care.
