Blunt Renal Trauma: A Case Report

Abstract

Aim: The ratio of renal traumas among all abdominal traumas is undeniable. With the developing technology, the non-operative approach took place of the operative interventions in the management of renal trauma. In this paper, we compiled a short review about renal trauma and its management based on a patient who was admitted to the emergency department with post-traumatic hematuria. Case: A 29-year-old man is admitted to the emergency department with a complaint of bloody urine and left flank pain. Medical history revealed that he fell down from a height of 1 meter 2 days ago. Left costa-vertebral angle (CVA) tenderness was positive on physical examination. Erythrocyte (1263 P/HPF) and Leukocyte (56 P/HPF) counts were elevated in urinalysis. The patient underwent contrast-enhanced abdominal computed tomography (CT) scan to rule-out kidney injury and left kidney contusion and perirenal hematoma that was in accordance with grade 2renal injury was detected. No intervention was not considered for the patient, he was admitted to the ward, and he was discharged after an uneventful hospital stay. Conclusion: The incidence of kidney injuries is higher in the young population aged between 31 and 38 years and men account for 72-93% of these cases. Blunt renal injuries, accounting for 71-95 % of renal trauma cases, are more common than penetrating injuries. Motor vehicle accidents are the main cause of blunt trauma, followed by falls, sports, and pedestrian accidents. Up to 95% of blunt renal injuries are minor and treated conservatively as in our case. Currently, conservative management is the preferred therapeutic modality in hemodynamically stable patients with low-grade kidney injury.
