Chronic kidney disease (CKD), also known as chronic renal disease (CRD), is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are non-specific, and might include feeling generally unwell and experiencing a reduced appetite. Often, chronic kidney disease is diagnosed as a result of screening of people known to be at risk of kidney problems, such as those with high blood pressure or diabetes and those with a blood relative with chronic kidney disease. Chronic kidney disease may also be identified when it leads to one of its recognized complications, such as cardiovascular disease, anemia or pericarditis.[1] It is differentiated from acute kidney disease in that the reduction in kidney function must be present for over 3 months.

Chronic kidney disease is identified by a blood test for creatinine. Higher levels of creatinine indicate a lower glomerular filtration rate and as a result a decreased capability of the kidneys to excrete waste products. Creatinine levels may be normal in the early stages of CKD, and the condition is discovered if urinalysis (testing of a urine sample) shows that the kidney is allowing the loss of protein or red blood cells into the urine. To fully investigate the underlying cause of kidney damage, various forms of medical imaging, blood tests and often renal biopsy (removing a small…...

Renal Failure

...deducted based on the answers provided. What are the differences among prerenal acute renal failure, intrarenal acute renal failure, and postrenal acute renal failure? Give examples of each Prerenal Acute Renal Failure The main differences between all the renal failures are the ways they are caused. For example, Prerenal acute failure occurs due to an altered renal blood flow. One example is going into surgery and losing a substantial amount of blood. Another example is having a constriction of the renal artery. Prerenal acute renal failure can also occur due to a water and electrolyte loss due to vomiting or diarrhea. In result, all of these causes will result in renal acute failure and acute tubular or interstitial necrosis. Intrarenal Acute Renal Failure Intrarenal Acute Renal Failure differentiates from the other renal failures because the cause is anything that attacks the actual kidney. For instance, drug use will increase the nephrotoxicity such as antibiotics. Further, renal diseases will contribute to intrarenal acute failure. Polycystic Kidney Disease will because tons of cysts build up in the kidney therefore destroying the kidney’s tissues and function and resulting into renal failure. Lastly Polynephritis will cause kidney failure due to kidney stones also destroying the kidney’s tissues when the patient is urinating. Postrenal Acute Renal Failure Postrenal Acute Renal Failure is different because the cause is due to an obstruction after......

Renal Hypertension

...Renal hypertension is an elevated blood pressure caused by kidney disease. It is caused by a narrowing in the artery that delivers blood to the kidney. Renal hypertension usually causes no symptoms. The narrowing in the arteries can't be felt. Unless it's dangerously high, high blood pressure causes no symptoms either. Symptoms of severely elevated blood pressure include: • Headache • Confusion • Blurry or double vision • Bloody (pink-colored) urine • Nosebleed The vast majority of people with renal hypertension never experience these (or any) symptoms. High blood pressure is dangerous partly because there are no symptoms, so organ damage can occur slowly without being recognized.Renal hypertension can cause chronic kidney disease. This is a slow decline in kidney function. Until the condition is well advanced, chronic kidney disease also causes no symptoms.Because there are usually no symptoms, a doctor may suspect renal hypertension when someone has uncontrolled high blood pressure despite multiple medications or has unexplained chronic kidney disease. With Renal hypertension due to renal artery narrowing, medications can effectively control blood pressure. In some people with renal hypertension due to narrowing of the renal artery, even taking three or more medications every day cannot adequately control blood pressure. In these situations, a procedure to improve blood flow to the kidneys can often help. Possible procedures include the following: Angioplasty,......

Renal Failure

...An Overview of Renal Failure and Its Treatment Option Renal failure can affect any population in society with no discrimination to age or race. There are several different types of renal failure and a multitude of treatment options depending on the severity or complexity of the disease process. With a change in healthcare on the horizon an examination into the area and the current school of thought is a must. While renal failure is just one small area of the healthcare sector, it is rapidly growing and affecting more and more every day. According to the data from the CDC more than 4.4 million Americans are diagnosed with some form of kidney disease (CDC). Renal Failure is best defined when the kidneys no longer work properly. Now one might ask, what do the kidneys do? The kidney’s simply remove metabolic waste and water from the human body and maintain homeostasis. Without the kidneys functioning properly the body will no longer make urine and dangerous electrolyte abnormalities can occur. One must realize there are several categories of renal failure. The two main classifications are Acute and Chronic Renal Failure. Acute Renal Failure is best defined as rapid and new onset renal failure sometimes reversible when treated appropriately while Chronic Renal Failure long term and irreversible unless treated via transplant. Now that a basic foundation definition of Renal Failure has been established, one must gain knowledge of what causes Renal Failure. Now that...

Pathophysiology of Cancer and Renal Failure

...Pathophysiology: Neoplasia and Renal System School of Nursing 1. Cancer Staging Cancer staging describes the severity of a person’s cancer based on the person’s initial tumor, and whether or not the cancer has metastasized (American Cancer Society, 2012, Knowledge of the stage is very important in that is can be used to explain prognosis to the patient, and can be used by the doctor and the patient to plan treatment. Staging of cancer is based on knowledge of the way in which cancer progresses in the body. Malignant cells grow and reproduce without any control or order, and they do not die when they should. In most cases the cancer cells will form a mass called a tumor. As the tumor grows it can invade tissues and organs that are close to it. The malignant cells can also break away from the tumor and enter the bloodstream (Lemone, 2004, p. 284). There are five common elements considered in most staging systems: site of the primary tumor, tumor size and number, lymph node involvement, cell type, and the presence or absence of metastasis. A common staging system is called TNM, which stands for Tumor, lymph Nodes, and Metastasis. When staging a number is added to each letter to indicate the size of the primary tumor and the extent of the cancer spread. (Lemone, 2004, p. 284) Infection, immunity and inflammation in cancer patients are all interrelated. They form what could be...

The Facts on Renal Cell Carcinoma

... The Facts on Renal Cell Carcinoma Carla Henthorn COM/156 5/30/14 Craig Carroll Did you know that the renal cell cancer (RCC) represents 2% of all cancers and about 5% of all epithelial carcinomas (Haase, 2012)? Renal cell carcinoma is a rare but treatable cancer, and collecting duct carcinoma is the rarest of kidney cancers. Renal cell carcinoma and collecting duct carcinoma come in many forms, and can grow to large masses undetected for years without signs or symptoms. By knowing your family history you can assess your risk factors, and possibly prevent getting this disease. Keeping up to date with your yearly exams and tests can prevent or at least catch it early enough to treat and or cure it. In the event you or a loved one does end up with renal cancer, joining a support group such as a greif support, would be beneficial in helping to deal with all the aspects of dealing with having cancer. Renal cell carcinoma is the most common primary malignant (cancerous) renal tumor affecting approximately 170,000 patient per year worldwide (Haase, 2012). With the death toll of about half of that per year. Although renal cell carcinoma is treatable, it can and has gone undetected by signs or symptoms for years. It is not until the patient notices a lump on their side that is uncomfortable when bending over that they suspect something is abnormal. Often the lump is not painful, it is just bothersome. This is how it can fully metastasize (spead to other organs or tissues)......

Renal Failure

...Renal failure In this paper we will discuss the cause and effect of renal failure. Renal failure is also known as kidney failure. Your kidneys provide many vital life sustaining functions and when they fail there could be many reasons for this from disease to damage. Depending on the severity of your renal failure your options may or may not be limited. Treatment options consist of Dialysis or kidney transplant. Renal failure is a reduction or total cessation of the glomerular filtration. Your kidneys provide many vital functions for your body to sustain life. Kidneys are responsible for filtering out the waste products from the body. You create waste from the food and drink that is indigested. Kidneys are also responsible for maintaining the water-salt balance in your system which in turn helps maintain blood pressure. They also help maintain the acid base balance in your body. Kidneys produce Erythropoietin, a hormone that travels to the red bone marrow, where it stimulates the production of red blood cells. Your kidneys also activate the vitamin D that is synthesized by your skin via the sun or ingested when we eat certain foods. The kidneys transforms vitamin D into a form that we can use called calcitriol. Calcitriol promotes the absorption and use calcium and phosphorus by the body. (J.G. & B.M. ch16) When your kidneys fail they are then referred to as renal failure. Renal failure can happen for many reasons. Renal failure can be acute, meaning immediate or......

Renal Paper

...The Effects of Different Types of Fluids on the Renal System Lisa Ta March 16, 2012. Biology 611.02 Principles of Human Physiology Butt, ShamimIntroduction Kidneys are a key function to the human body because it regulates plasma volume, ionic composition, osmolarity, pH, and removes metabolic waste products and waste substances. All these regulations work together to maintain homeostasis in the body. A person has five liters of blood circulating the body and twenty percent (which is one liter) of blood is circulated to the kidneys. The functions of the kidneys are the billions of nephrons they contain that filter the blood. Each nephron contains the renal corpuscle and renal tubules. The renal corpuscle contains the Bowman’s capsule and glomerulus and the renal tubules contain the proximal tubule, loop of Henle, distal convoluted tubule, and the connecting tubule to connect to the collecting duct. The proximal tubule has two parts: the proximal convoluted tubule and proximal straight tubule. The loop of Henle is split into three parts: the descending limb, thin ascending limb, and thick ascending limb. Blood first enters through the afferent arteriole, into the glomerulus and is filtered out to the Bowman’s capsule. The filtrate is called the glomerular filtrate, which is the protein-free plasma, that goes through the proximal convoluted tubule, then to the proximal straight tubule, through to the descending loop of Henle, up the thin ascending loop of......

Renal Case Study glomerulonephritis. The injured and defective glomeruli in the kidneys lead to the release of too much protein in the urine resulting in nephrosis. 2. Use JH’s laboratory values to determine if he is still experiencing nephrosis or if his condition is progressing to renal failure. JH’s lab values indicate that the PaCO2, HCO3-, and Hct, and Na levels are all below normal limits. His potassium level was increased at 5.4 mEq/L. There was also an increase in JH’s BUN (58 mg/dl), creatinine (3.9 mg/dl), and albumin (2.0 g/dl) levels. Traces of protein were found in his urine suggesting that JH’s condition is progressing to renal failure. 3. What additional physical or laboratory findings would be helpful in determining JH’s degree of renal impairment? Creatinine clearance is helpful in determining general kidney function. A level above 1.2 is reduced and indicates renal impairment. The kidneys' ability to handle creatinine is called the creatinine clearance rate, which helps to estimate the glomerular filtration rate (GFR). This rate will give a general overview of how the kidney is functioning. Physical assessment findings of joint pain, tenderness, redness and swelling are all indicative of renal impairment from hyperuremia. Skin nodules, generalized itching/pruritus may be present upon assessment of the integument. Patient may also complain of flank pain. Decrease in urine output may lead to patient experiencing edema, increased lethargy due low Hct level and......

Renal System

...Renal system urinary system Kidneys The kidney job is to filter metabolic wastes excess iron and chemicals from the blood to form urine. Every day the two kidneys filter about 120 to 150 quarts of blood to be able to produce 1 to 2 quarts of urine, composed of wastes and extra fluids. The urine flows from the kidneys to the bladder by 2 thin tubes of muscle called ureters one tube on each side of the bladder the bladder will then store the urine. The kidneys are important because they keep the composition or make up if the blood stable which in turn will help the body function. The left kidney is located slightly higher than the right kidney because of the liver but more because of the right side of the liver because the right side of the liver is much larger than the left side of the liver. Urinary Bladder The bladder is located in the pelvis between the pelvic bones the bladder is hollow and a muscular balloon shaped organ that expands when it is filled with urine. Though a person cannot control kidney function they however can control when the bladder empties. A normal bladder can act like a reservoir and can hold up to 1.5 to 2 cups of urine, how often does the person needs to urinate depends on how fast the kidneys produce the urine that fill the bladder. Urethra The urethra is a tube which passes urine from the bladder to the exterior of the body, the female urethra is approximately 2 inches long and ends inferior to the clitoris and superior to the vaginal...

...capillary pressure. And if there is a low blood flow we will have a vasodilation. 2. What happens to GFR if the diameter of the afferent arteriole is increased? Why? (2 points) We will have an increase of pressure in the glomerulus, more blood can get in there than can get out, so if there is an increase of volume there will be increase of pressure and increase of GFR. 3. What happens to GFR when blood pressure is increased? (1 point) If arterial pressure increases, the renal blood flow would increase, leading to increase in GFR and an increase of urine output. 4. What happens to GFR when the diameter of the efferent arteriole is increased? (1 point) The GFR will decrease. Because pressure will decrease, more blood can exit than enter, so we will have less volume and pressure. Activity 3: Understanding Tubular Reabsorption and things that affect it. 1. Define Tubular reabsorption (1 point) Tubular reabsorption is the movement of solutes and water from the lumen of the renal tubules back into the plasma. Without reabsorption, we would excrete the solutes and water that our bodies require for homeostasis. 2.
