Introduction:
During the past decades, kidney transplants have spread amongst many countries and finally all over the world. That was mainly due to the doctors’ opinions toward this effective kind of operation. In the beginning, doctors used to think that there were no other solutions to curing end-stage kidney disease (ESRD) 1, kidney failure and several other abnormalities related to this important organ other than dialysis. In addition, professors and doctors were not convinced about the outcomes of kidney transplants, thus they were applying this procedure as the last alternative way of treatment.
Briefly, kidney is the organ functioning as a filter in the body, which has multiple vital functions including the process of exertion of waste products and poisonous materials that result from our daily digestion of various types of food that accumulate in the blood which the body cannot function normally when those substances are in the body. Therefore, the kidney filters the blood, assembles the unwanted products and excretes them as means of urine. In addition, the kidney does regulate the amount of salt and electrolytes inside of the body so that it maintains the blood pressure circulation level accurately. Furthermore, the kidney contributes to the synthesizing of blood cells by the secretion of certain kinds of hormones the target the bone marrow. In other words, the kidney is the responsible organ for several vital functions that in turn it keeps the homeostasis under normal levels so the body can function efficiently.
The process of continuous dialysis only treated several kidney diseases such as end-stage renal disease and kidney failure, which is uncomfortable for the patient’s lifestyle. Recently, most of the patient...

The article has been well organized and written. Mackay clearly states her rationale for writing the article and provides a valid reason to hold up her article with sources. Within the introduction section, the authors present worrying statistics of Americans affected by kidney disorders. Moreover, the author provides the disadvantages of dialysis with only Kidney transplantation being the only option. The author relates the topic to the readers...
Hemodialysis is the process of blood that is transported outside the body to a dialysis machine where it is cleaned of waste products and returned to the circulatory system. It is a lifetime requirement. As a result, of the repeated and life-long needle puncture of the involved blood vessels, thick scar tissue eventually develops which makes the procedure difficult and painful. To avoid this complication, a surgical procedure known as an arteriovenous fistula is performed. It produces a large vein that can be entered safely and easily with large needles for the three times a week procedure. New techniques are intended to improve the efficiency of dialysis and thereby increases life expectancy, as 20% of people with end-stage renal disease die annually. Peritoneal Dialysis. Peritoneum is the lining of the abdominal cavity. The tissue has the properties of a semi-permeable membrane, allowing the process of diffusion to take place in abdominal cavity. An incision is made through the anterior abdominal muscle wall; through this opening, a tube (catheter) is inserted into the abdominal space. Sterile dialysate (a solution to clear waste products) is introduced and allowed to remain in the cavity four to six hours or overnight. During this time, through the process of diffusion, impurities pass through the peritoneum into the dialysate. The dialysate and its collected impurities are then eliminated from the body. Kidney transplantation when possible, is the best alternative for end stage renal disease. Often, the body rejects the kidney and when this occurs the recipient must undergo a medication regimen to suppress the immune system. Relatives are recommended to donate their liver so that the body has a smaller chance to reject the kidney. I comparison with dialysis kidney transplantation has advantages that positively affect the person’s medical and vocational rehabilitation potential. The person with the

Currently there are two types of renal replacement therapy. The original dialysis which we called it hemodialysis used for patients with chronic renal failure, needs the patients to come to hospital 2-3 times per week. This type of dialysis called the intermittent hemodialysis .However the intermittent hemodialysis is difficult to do it in the intensive care population with acute renal failure because of the hemodynamic instability and those type of patients usually are the most sick and critically ill patients within the intensive care units and have multiorgan dysfunctions, so medically is too difficult to do for them intermittent hemodialysis. In addition intermittent hemodialysis will increase the mortality and morbidity among them. Within the modern intensive care units new way of dialysis has been developed 30 years ago called continuous renal replacement therapy (CRRT).The definition of (CRRT) is any extracorporeal blood purification therapy intended to substitute for impaired renal function over an extended period of time and applied for or aimed at being applied for 24 hours/day, Bellomo R., Ronco., Mehata R. The CRRT was found because the traditional way of ...
Without proper working kidneys, blood pressure can rise, body fluids accumulate and red blood cell count can decrease. Usually kidney problems occur from disease, conditions and disorders. Disease can come from damage to nephrons, which help filter the blood. Infections can travel from the bladder up to the kidneys. Kidney cancers, kidney stones, cysts and injury all can damage a kidney. Without properly working kidneys, our heart, lungs and brain, as well as other organs are put in danger. (Capicchiano 2013) Kidney dialysis is not always a permanent need; sometimes it is needed for a short time. Kidney dialysis can occur in many places, the hospital, a home or in a center. Often people return to work after dialysis, unless their job involves strenuous activity such as heavy lifting or digging. (Lewin, 2010)

Healthy kidneys clean the blood by filtering out extra water and wastes. They also make hormones that keep your bones strong and blood healthy. When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys.
To the majority of Americans, dialysis is a confusing process that they will hopefully never have endure, but for hundreds of thousands people, it is a daily fact of life. According to US News and World Report, “In the United States, almost 400,000 people undergo dialysis every year.” (Gordon, 2012, para. 4) Their lives revolve around receiving dialysis three days a week for three to four hours per treatment, usually at an outpatient clinic. While dialysis can prolong the end stage renal disease (ESRD) patients’ life, the three day a week trudge to this clinic can feel like and endless cycle of discomfort and inconvenience. Fortunately the ESRD patient has more than one option, namely, peritoneal dialysis.
Kidney Function Introduction and definition of terms: The kidneys are the main organs in the urinary system. They filter waste products out of blood from the renal artery. These are then excreted. Useful solutes are reabsorbed into the blood. They also have a major homeostatic role in the body, and help to control the water content (osmoregulation) and pH of the blood.

For many years, medical researchers have been working in an effort to develop blood vessels, urine tubes, skin tissue, and other living organs. However, developing whole, fully functioning organisms, including all cell structures, is very difficult. This is where 3D printers make a groundbreaking impact. Due to their great precision and process, they are able to reproduce the vascular systems required to make organs functional. Scientists are already using these machines to print small, individual strips of organ tissue.
People nowadays might get the impression that the 3D printing technology is a relatively new concept in our daily life. However, 3D printing technology is invented and utilized in many fields such as creating human organs in healthcare, building architectural models in engineering, even forming components that can be used in aeronautic fields long ago. Since Charles W. Hull has invented the 3D printing technology in the 1980s, scientists, engineers, and even normal people were and still are trying to discover more possibility of the usages and changes on this technology. Same as every invention of the new technology, with its undeniable beneficial effects, 3D printing also faces lots of limitations
Furthermore, they are involved in the reabsorption of nutrients in the bloodstream and they can regulate the acidity of the blood. Besides the regulation of the fluids and ions, the kidneys are also responsible for the regulation of many different hormones that are involved in homeostasis and metabolism. Because of their importance in the regulation of substances in the body, when the kidneys stop working properly all the body is influenced by that creating disequilibrium in the maintenance of homeostasis and control of all the metabolic functions which can indirectly cause other problems to the body.... ... middle of paper ... ...
Nowadays, 3D has become an over buzzed word: be it with displays, movies, mobiles or the newer addition: Printers. 3D printers are much similar to traditional printers but instead of printing a image they build an object. The magnitude of the impact can begin from printing fine delicate jewellery to state of art jet engines or even houses. 3D printing though an old technique but has evolved a lot in recent few years from being a technology trigger to reaching a sustaining plateau on the Gartner’s Hype curve.
Imagine printing what ever it is you need from your own office or home. In addition to that, you will have full control customizing the product and the printer will have no difficulties achieving your designs. All you have to buy is the ink and the material additives and the printer will do the rest.
