*Purpose: Unintentional injuries result in over 30 million emergency room visits annually in the United States. With almost 20 thousand renal transplants performed in 2017, and an estimated 100 thousand patients with functioning renal transplants alive in the United States, it is likely that hospitals will encounter trauma patients with renal allografts. Timely expert management for these patients can save organs that would otherwise be lost.
*Methods: We present a 60 year old male transferred to a level 1 trauma center 13 hours after a motor vehicle collision. The initial trauma evaluation revealed cervical spine, rib, and patellar fractures, and a subcapsular hematoma of his transplant kidney (figure 1). He was alert and oriented with normal blood pressure, normal urine output, but an elevated creatinine of 2.1 mg/dl (baseline 1.1mg/dl). Transplant surgery was consulted and his creatinine rose to 2.8mg/dl despite fluid resuscitation. Doppler ultrasound revealed reduced arterial blood flow to the allograft (figure 2), and he was taken emergently to the operating room for evacuation of the hematoma. On post-operative day 1 his creatinine improved to 1.3mg/dl, and to 0.8mg/dl on post-operative day 2.

*Conclusions: Page kidney phenomenon arises from compression of renal parenchyma by a subcapsular hematoma. Hypertension, oliguria, and renal dysfunction are the most common presenting sequelae, with decompression of the hematoma being the treatment of choice in the transplant population. Prompt recognition and management in the trauma setting requires a high index of suspicion as signs of allograft compromise can be assigned to other causes.
