Acute renal infarction: a single center experience

et al. 2016

Background Acute renal infarction is a rare condition whose diagnosis is often delayed. Major risk factors include atrial fibrillation, valvular or ischemic heart disease, renal artery thrombosis/dissection and coagulopathy. MethodsWe reviewed the medical records of 18 patients admitted to our Nephrology Department between 1999 and 2015 for acute renal infarction diagnosed by computed tomography. Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy was performed in some patients during follow-up to assess parenchymal lesions and estimate differential kidney function. ResultsMean age was 59.8 years. Major associated risk factors included hypertension (44 %), obesity (33 %), atrial fibrillation (28 %), peripheral vascular disease (17 %), smoking (17 %), prior thromboembolic event (11 %), diabetes (11 %), estroprogestinic therapy (11 %). Seventy-two percent of patients presented with flank pain. Mean serum creatinine was 1.2 ± 0.6 mg/dl. Acute kidney injury occurred as the initial manifestation in two patients. Patients were managed conservatively, with low molecular weight heparin (83 %) or aspirin (11 %). At the end of follow-up serum creatinine was 1.1 ± 0.3 mg/dl; one patient remained on chronic hemodialysis. 58 % of patients who underwent renal scintigraphy after a median of 8 months had a reduced contribution of the previously affected kidney to total renal function. ConclusionRisk factors associated with the development of chronic kidney disease following renal infarction are unknown. In our subjects, renal function remained stable in all but one patient who developed end stage renal disease. Further studies should focus on etiology and evolution of kidney function in patients with acute renal infarction. IntroductionAcute renal infarction, due to an abrupt interruption of renal arterial flow, is a rare condition with an estimated incidence of 0.004-0.007 % in the Emergency Department setting [1,2]. Non-specific clinical presentation mimicking other pathologic states (e.g. urolithiasis, acute pyelonephritis, other acute abdominal diseases) often causes a delay in the diagnosis, which may increase the risk of impaired renal failure [3][4][5]. Radiologic diagnosis of renal infarction is based on enhanced contrast computed tomography (CT), which typically indicates the presence of a wedge-shaped hypodense area in the peripheral region [2]. Major risk factors for renal infarction include atrial fibrillation, valvular or ischemic heart disease, renal artery thrombosis/dissection and coagulopathy. Etiology remains unknown in many cases [4,6,7]. We describe the clinical and radiological characteristics and renal prognosis of 18 patients with acute renal infarction.

“…[7][8][9] Acute renal infarction may manifest clinically as a pain similar to renal colic, and is often misdiagnosed as an acute pyelonephritis or renal colic because of similar presenting symptoms, as shown in the present case. [6,12] Also, in this case, we suspected tumor metastases of bilateral kidneys.…”

Bilateral Renal Infarction in a Patient with Lung Carcinoma Treated with Cisplatin and Gemcitabine

et al. 2007

The administration of antineoplastic agents are associated with various vascular events. A case of acute bilateral renal infarction in a patient with non-small cell lung carcinoma during chemotherapy with cisplatin and gemcitabine is reported. The patient was misdiagnosed as having renal colic. To our knowledge, bilateral renal infarction following cisplatin and gemcitabine has not been reported previously. Renal infarction should be considered in the differential diagnosis of flank pain in a patient treated with gemcitabine and cisplatin.

Acute Renal Infarction: An Underdiagnosed Disorder

Acute renal infarction is usually diagnosed when the triad of flank pain, hematuria and elevated lactate dehydrogenase is observed. Since the symptoms are non specific, diagnosis requires high degree of suspicion or may be missed or confused with renal colic. The incidence of ARI in emergency department visits is 0.007 % whereas in autopsy series is reported 1.4 % indicating the condition goes undiagnosed frequently. With the increase use of contrast enhanced computed tomography and magnetic resonance angiography the accuracy might be improving at the present time.
