“…In this case, it was characterized by the acute occurrence of hypertension with concomitant decrease in kidney function. 4,6 The pathophysiology of hypertension associated with renal compression from perinephric hematoma or chronic peri-renal scarring results from intrarenal artery or segmental branch stenosis. 7 One explanation is that rapid deceleration stretches the renal artery, causing an intimal injury that leads to arterial obstruction and ischemia.…”

Renal transplantation is the treatment of choice for end-stage renal disease in children. As a technically demanding surgery with complex medical management, it is associated with a number of complications. Anatomic imaging including ultrasonography with color and spectral Doppler and functional assessment with renal perfusion scintigraphy are complementary for the detection and characterization of posttransplant complications. Complications can be characterized by the time of appearance after transplantation (immediate, early, or late) or the anatomic site of origin (perinephric, vascular, urologic, or renal parenchymal). Perinephric fluid collections include hematomas and seromas, abscesses, lymphoceles, and urinomas. Noninfected collections frequently resolve spontaneously but should be monitored to exclude progression. Vascular complications are more prevalent in pediatric patients because of the small vessel caliber and include vascular thrombosis and stenosis. Arteriovenous fistulas and pseudoaneurysms can complicate biopsy and are typically transient. Common urologic complications include urine leak and urinary tract obstruction. Renal perfusion scintigraphy can be invaluable in elucidating the nature of such complications. Renal parenchymal abnormalities include acute tubular necrosis, rejection, and toxic effects of medication. Imaging features of renal parenchymal abnormalities can overlap, and the primary role of imaging is to exclude alternative causes of renal dysfunction. Renal and nonrenal mass lesions are more common in immunosuppressed patients after transplantation. Familiarity with the normal imaging appearance of the renal allograft and the appearances of common complications facilitates accurate diagnosis and timely treatment, with the ultimate goal of increasing graft survival. This goal is particularly crucial in children, given their greater number of projected life years.

“…Cases have been described in young healthy athletes with new-onset hypertension arising several years after sports-related trauma [4]. Other common preceding events include motor vehicle accidents, mass lesions and renal allograft surgery [5, 6]. Hypertension in these cases is generally long-standing but can rise acutely, causing malignant hypertension [7].…”

New-onset arterial hypertension is a well-recognised complication of kidney trauma. Cases have been described in young healthy athletes with hypertension arising years after sports-related trauma. The pathophysiology of this disease is thought to arise from intrarenal arterial stenosis resulting from rapid deceleration during the initial injury. This leads to arterial obstruction and ischaemia with increased secretion of renin, eventually leading to elevated blood pressure. Though hypertension in these cases is generally gradual in onset and long-standing, it can also rise acutely, leading to malignant hypertension. We present the case of a 17-year-old male who presented with refractory hypertension following blunt trauma to his left kidney during a recent sporting injury. This is followed by a discussion of the relevant literature in this area to date, highlighting the key challenges involved in the management of these patients.
