INTRODUCTION AND IMPORTANCE: High-grade renal trauma, classified as grades 4 and 5 by the American Association for the Surgery of Trauma (AAST), often requires surgical intervention due to the potential for significant morbidity. However, non-operative management (NOM) has emerged as a valuable approach for selected patients, aiming to preserve renal function and minimize complications. CASE PRESENTATION: This article reviews the case of a young male patient with isolated blunt high-grade renal trauma managed conservatively, alongside an examination of current trends and outcomes associated with NOM in similar cases. This case illustrates the successful application of conservative management in a young patient with high-grade renal trauma. Current literature supports NOM for hemodynamically stable patients, emphasizing close monitoring, pain management, and the use of interventional radiology when necessary. CLINICAL DISCUSSION: Studies indicate that NOM can achieve high renal preservation rates while reducing the need for nephrectomy and minimizing surgical complications. Conservative management of high-grade renal trauma can be an effective alternative to surgical intervention in carefully selected patients. CONCLUSION: This case reinforces the potential of NOM to preserve renal function while mitigating the risks associated with operative approaches. Continued research is essential to refine selection criteria and optimize long-term outcomes for patients with renal trauma.
