Renal impairment encompasses both acute and chronic renal failure, which may develop as a result of numerous disorders. The clinical presentation ranges from asymptomatic to life-threatening shock, depending on the severity of impairment. The diagnosis rests on the ability of the physician to recognize clinical features and conduct a thorough laboratory workup, while the determination of the glomerular filtration rate is the cornerstone in determining the degree of renal failure.
Presentation
A myriad of disorders may cause the inability of the kidneys to perform their respective function, and the term renal impairment encompasses two major disorders - acute and chronic kidney failure:
- Acute renal failure (ARF) can stem from diseases of pre-renal (severe bleeding, hypovolemia, extensive burns, renal hypoperfusion, heart failure, liver cirrhosis, etc.), intrinsic renal (the glomeruli, the tubules, the interstitium, and/or the renal blood vessels), and post-renal systems (obstructive uropathy arising from blood clots, tumors, or congenital defects) [1] [2]. Patients in the intensive care unit who are critically ill are most susceptible to ARF [1] [3], who present with symptoms of shock due to the severe effects of hyperkalemia, metabolic acidosis and diminished glomerular filtration rate (GFR) [2].
- Chronic renal failure - Contrary to ARF, a slowly progressing course of symptoms is seen in chronic renal impairment. At first, patients may be completely asymptomatic, but signs such as alterations in urinary habits (nocturia), generalized weakness, and fatigue eventually ensue [4] [5]. As chronic renal failure is an irreversible and progressive process, further deterioration of kidney function leads to neuromuscular symptoms (hyperreflexia, cramping, neuropathies, or even convulsions), weight loss, nausea, pruritus, and anorexia [4] [5]. The last stage of chronic renal failure, termed end-stage renal disease (ESRD), can include all of the mentioned symptoms, as well as muscle wasting, depression, anxiety, constipation, sleep disturbances, restless legs, and dyspnea [2] [4] [6].

- Renal Function Decreased
INTRODUCTION: The glomerular filtration rate (GFR), a measure of renal function, decreases by approximately 10 mL/min every 10 years after the age of 40 years, which could lead to the accumulation of drugs and/or renal toxicity. [ncbi.nlm.nih.gov]
Workup
Renal impairment, both in the form of acute and chronic renal failure, could be severely harmful and even life-threatening for the patient in the absence of an early diagnosis [1]. For this reason, physicians must obtain a thorough patient history and determine the presence of underlying disorders that may induce renal impairment, whereas a complete physical examination assesses the signs and symptoms and determine the next steps in workup [2]. In fact, the clinical examination can lead to a prompt diagnosis in some cases, examples being prostate hypertrophy and cervical cancer, where the physician might be able to palpate the masses during rectal and vaginal examinations, respectively [1]. As soon as a presumptive diagnosis is made, a meticulous laboratory workup needs to be performed. A complete blood count (CBC), kidney function tests (urea and creatinine), urinalysis, serum glucose levels, complete coagulation panel, serum electrolytes (sodium, potassium, bicarbonate, calcium, and phosphate), inflammatory parameters (erythrocyte sedimentation rate, C-reactive protein), liver transaminases, and in most severe patients, arterial blood gasses must be included [1] [2] [5]. Imaging studies are equally important in determining the cause of kidney failure, with abdominal ultrasonography being the gold standard for evaluation of kidney anatomy and structure [1] [5]. To assess the degree of kidney failure, determination of GFR using creatinine and specific calculations is vital in establishing the severity of renal impairment [1] [5].
