Renal trauma

Harjoat Riyat, Richard Jones, Debashis Sarkar, Richard Stephenson
Kidney laceration following blunt trauma is responsible for up to 3% of trauma cases. The risk factors associated with renal injury are attributed to the risks of mechanical injury. However, anatomical variations that may accelerate the insult of injury are poorly documented. This case report describes a 25-year-old with degenerative lumbar scoliosis who presented with flank pain and visible haematuria following a low-impact injury. The patient had a grade IV renal injury. The curvature of the spine, shown on CT imaging, revealed a reduced retroperitoneal space around the left kidney...

OBJECTIVE: To determine if traumatic renal injuries and/or computed tomography (CT) findings are predictive of HTN development following injury. METHODS: A retrospective review of a renal trauma database was performed from 1995-2015. Renal injuries were graded by the American Association for the Surgery of Trauma system, with high grade defined as 4 or 5. Non-renal genitourinary (GU) trauma (i.e. bladder, penile, urethral, and testicular) patients were selected as controls...

A renal artery pseudoaneurysm is a rare but important complication that can occur after renal trauma, renal biopsy, percutaneous nephrostomy, percutaneous nephrolithotomy (PCNL), and partial nephrectomy. The incidence of this potentially life-threatening complication is less than 1%, but is likely to increase with the increasing popularity of endoscopic renal procedures. We present a case of a 30-year female who underwent right PCNL for a right renal pelvic stone. Two weeks later, she presented with massive hematuria...

BACKGROUND: Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unusual causes immediately after kidney transplantation. CASE PRESENTATION: A 66-year-old man, whose wife donated a kidney, underwent ABO-compatible living kidney transplantation...

Idarucizumab, a humanized monoclonal antibody fragment (Fab), provides rapid and sustained reversal of dabigatran-mediated anticoagulation. Idarucizumab and dabigatran are mainly eliminated via the kidneys. This analysis aimed to characterize the renal elimination of idarucizumab and investigate the influence of idarucizumab on the pharmacokinetics (PK) of dabigatran and vice versa. Studies were conducted in 5/6 nephrectomized rats, in human volunteers with and without renal impairment, and in a porcine liver trauma model...

CONTEXT: Haematuria is a common urological presentation associated with patient anxiety and clinically relevant underlying pathology. However, the prevalence and pathophysiology of haematuria following sporting exercise is less well documented. OBJECTIVES: This review paper seeks to clarify the prevalence of microscopic and macroscopic haematuria in association with sporting exercise reported in the literature, and the pathophysiology behind it. We review the relation of haematuria to injury to the urinary tract in sport, as well as the incidence of underlying disease, urological and incidental, following investigation for exercise-induced haematuria...

Isolated spontaneous renal artery dissection (RAD) without known trauma is rare, and its etiology has not been determined. However, notable risk factors including hypertension, strenuous exercise, connective tissue disorders, atherosclerosis, extracorporeal shock wave lithotripsy, and cocaine abuse have been reported. To the best of our knowledge, isolated RAD caused by lumbar vertebra osteophytes in patients with degenerative lumbar scoliosis has not been reported in the literature. In this article, we present a case of RAD caused by lumbar vertebra osteophyte in a patient with degenerative scoliosis and discuss the management of the disease...

The naked mole rat (Heterocephalus glaber, Rüppell, 1842) is a unique eusocial rodent with unusually long lifespan. Therefore, the study of spontaneous and experimentally induced pathologies in these animals is one of the most important tasks of gerontology. Various infections, noninfectious pathologies (including age-dependent changes), and tumors have been described in the naked mole rat. The most frequent pathologies are traumas (bite wounds), purulent and septic complications of traumatic injuries, renal tubular calcinosis, chronic progressive nephropathy, hepatic hemosiderosis, testicular interstitial cell hyperplasia, calcinosis cutis, cardiomyopathy, and dysbiosis-related infectious lesions of the digestive system...

Acute Kidney Injury (AKI) complicating major trauma is associated with increased mortality and morbidity. Traumatic AKI has specific risk factors and predictable time-course facilitating diagnostic modelling. In a single centre, retrospective observational study we developed risk prediction models for AKI after trauma based on data around intensive care admission. Models predicting AKI were developed using data from 830 patients, using data reduction followed by logistic regression, and were independently validated in a further 564 patients...

Ultrasound (US) is the first-line imaging modality for evaluating azotemic patients for urinary obstruction and renal size. US is also valuable for distinguishing congenital variants and simple cystic lesions from renal masses. Doppler US is effective in detection of renal calculi and evaluation of vascular pathology. Unfortunately, renal US is limited in distinguishing causes of medical renal disease. The kidneys have a complex internal architecture with a highly variable appearance on US. This article illustrates non-neoplastic renal conditions, including normal and embryological variants, parenchymal, cystic, and vascular diseases...

OBJECTIVES: Albumin is used to resuscitate trauma patients but may increase intracranial pressure (ICP). Its effects on renal blood flow and function are unknown. Our aim was to examine the effects of hypertonic albumin on ICP and renal function, and if any effects are due to the hypotonicity of the solution containing albumin or to albumin itself. DESIGN, SETTING AND SUBJECTS: Cross-over, randomised controlled experimental study of six adult Merino ewes in the animal facility of a research institute...

The Page kidney is a rare phenomenon. External renal parenchymal compression is the culprit. We report two cases of young males with flank pain, renal mass, and hypertension with history of blunt abdominal trauma. Initially, hypertension was controlled by angiotensin-converting enzyme (ACE) inhibitors but gradually became refractory to medical treatment. Laparoscopic nephrectomy was performed in both patients. We emphasize the Page kidney as a cause of hypertension in young patients, presenting with flank pain and renal mass with or without complications of hypertension...

Renal abscesses are uncommon in otherwise healthy children and adolescents who have no underlying renal structural anomalies. A previously healthy, immunocompetent, 14-year-old male without a history of abdominal trauma or urinary tract infection (UTI) was found to have a renal hematoma that became infected and developed into a renal abscess. He presented with a 2-day history of nausea, vomiting, fever and 1-day history of abdominal pain that radiated to the right flank. Clinical examination, blood work, and initial imaging indicated likely infection; however, findings were normal on urinalysis and urine culture had no growth...
