Kidney transplant and dialysis are two options for patients with kidney failure. A kidney transplant involves surgically implanting a donor kidney by connecting the artery, vein and ureter. The transplant takes about 3-4 hours under general anesthesia. Dialysis works by diffusing solutes and fluid across a semi-permeable membrane from the blood to a dialysate fluid to remove waste, with hemodialysis being the most common type where blood is cleaned in a dialysis machine and returned to the body.

PROCEDURE
Presentation kidney
Kidney failure patients have two main treatment options: kidney transplant or dialysis. A kidney transplant involves surgically placing a donor kidney into the patient, typically connecting the donor kidney's artery and vein to the recipient's iliac artery and vein. Dialysis provides an artificial replacement for lost kidney function and works by circulating the patient's blood through an external filter to remove wastes and excess water. The two main types are hemodialysis, which uses a machine to filter blood outside the body, and peritoneal dialysis, which filters blood inside the body.
DIALYZER / ARTIFICIAL KIDNEY
A dialyzer is a mechanical device that acts as an artificial kidney by removing waste and excess fluid from the blood. It contains semi-permeable membranes made of thin fibers with microscopic pores that allow small molecules like toxins and water to pass through but keep larger molecules like blood cells and protein inside the blood. Modern dialyzers consist of hollow fiber membranes encased in a rigid cylindrical casing and can filter the equivalent area of 1-2 square meters. Dialyzers come in external, implantable, and wearable forms to provide hemodialysis treatment for kidney failure patients.
DIALYZER
Overview dialysis machines are artificial kidney that perform most, but not all, kidney function for patients who have permanent or temporary renal failure
The machine use HEMODIALYSIS to cleanse the blood and balance its constituents.
THE DIALYSIS TEAM
The dialysis team is comprised of qualified healthcare professionals who provide quality dialysis treatment to eligible patients. The core members of the team include nephrologists, nurses, dietitians, social workers, technicians, surgeons, and coordinators. Each member has specialized training and responsibilities to ensure patients receive proper medical care, support, and monitoring before, during and after dialysis treatments. The overall goal of the multi-disciplinary team is to help patients effectively manage their kidney disease and maintain quality of life.
Artificial kidney
This document provides an overview of kidney function and different types of dialysis used to treat kidney failure. It outlines that the kidneys filter waste and excess fluid from the blood. When the kidneys fail, dialysis is needed to perform these functions externally or internally. There are two main types of dialysis - hemodialysis which filters blood outside the body using a machine, and peritoneal dialysis which uses the peritoneal membrane in the abdomen to filter blood inside the body. Both have benefits and limitations in treating kidney failure.
Dialyzer
This document discusses dialyzers, which are used in renal dialysis to remove waste and excess fluid from the blood of patients with kidney failure. It describes the key components of a dialyzer, including the semipermeable membrane and four ports, as well as specifications like surface area, clearance rates, and sterilization methods. Various types of dialyzers are covered, such as coil dialyzers, parallel plate dialyzers, and hollow fiber dialyzers. Membrane materials including cellulose, synthetic, and cellulosynthetic are also outlined. An ideal dialyzer is said to efficiently clear toxins while avoiding protein and cell losses.
Human excretion
Dialysis machines, also known as kidney machines, pump a patient's blood out of their arm artery, through an artificial kidney or dialysis tubing that acts as a semi-permeable membrane, and back into their vein. The dialysis tubing runs through a salt water tank, filtering out waste and excess fluid from the blood while keeping blood cells and protein inside, similar to the function of healthy kidneys.

Chapter 11 Excretion Lesson 3 - The 2 functions of kidneys and Kidney failure
The kidneys have two main functions: excreting waste in urine and regulating water balance in the blood. To regulate water balance, the kidneys control the amount of water reabsorbed based on the hormone vasopressin. When the body loses water, vasopressin levels rise, causing the kidneys to reabsorb more water and produce less urine. When water intake is high, vasopressin levels fall, causing the kidneys to reabsorb less water and produce more dilute urine. Kidney failure can result from diabetes, high blood pressure, inherited disease, or other causes, and requires dialysis to filter waste from the blood.
Biology 38.3
The excretory system removes waste from the blood. The kidney filters blood, removing urea and excess water. The ureter carries urine from the kidney to the urinary bladder, where it is stored until the urethra releases it from the body. Each kidney contains millions of nephrons that filter blood and regulate water balance and pH levels to maintain homeostasis.
artificial kidney
The document summarizes a seminar presentation on artificial kidneys. It introduces the topic of artificial kidneys and dialysis machines, which are used to filter blood when the kidneys are damaged or failing. It describes how dialysis machines work by using a semi-permeable membrane to separate waste and excess water from the blood. The document also outlines some of the causes and symptoms of renal failure, as well as diet and treatment considerations for patients undergoing dialysis.
Urinary system
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra which work together to produce, store, and eliminate urine. The kidneys filter waste from the blood and regulate fluid levels, while the ureters carry urine from the kidneys to the bladder. The bladder stores urine until emptying via the urethra. Common urinary tract infections occur when bacteria like E. coli enter the bladder or kidneys, causing symptoms like painful urination and back pain. Risk factors for UTIs include being female due to anatomy and not drinking enough fluids. Proper hygiene and urinating after sex can help prevent infections.
Urinary System 2
The document discusses the structure and function of the urinary system. It describes how the kidneys filter waste from the blood to produce urine, and how the ureters then carry urine from the kidneys to the bladder for storage.

The kidneys filter blood to form urine and regulate fluid and electrolyte balance. The nephron is the functional unit of the kidney and includes the glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. Urine passes from the kidneys through the ureters to the bladder for temporary storage before being released through the urethra.
Urinary System by Hana Jakubickova
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine. Each kidney contains approximately 1 million nephrons, the functional units that filter blood. The kidneys regulate fluid and mineral balance, produce hormones, and remove wastes from the body. When the kidneys fail to function, renal replacement therapies such as hemodialysis, peritoneal dialysis, or kidney transplantation are needed.
Urinary system
The urinary system consists of paired kidneys, ureters, a urinary bladder, and a urethra. The kidneys filter waste from the bloodstream and regulate water and electrolyte balance. Each kidney contains nephrons with a glomerulus and tubular sections that allow for filtration, reabsorption, and secretion of substances. Urine travels from the kidneys through ureters to the bladder, where it is stored until excretion through the urethra. Key functions include filtering toxins and wastes from the bloodstream and regulating water balance through antidiuretic hormone.
1. excretion introduction
The document summarizes excretion and the structure and function of the kidney and nephron in homeostasis. It explains that excretion removes metabolic waste from the body through organs like the lungs and kidneys. The kidneys play a key role by filtering the blood to remove urea and excess salts and water to produce urine, which is then removed from the body. The nephrons are the functional units of the kidney that filter blood and reabsorb necessary molecules while removing waste to form urine that passes through the kidney and ureter to the bladder.

Urinary system
Acute tubular necrosis (ATN) is a condition where the renal tubules are damaged by toxins or lack of oxygen, commonly caused by medications, contrast dyes, or liver/kidney diseases like diabetes. Blood urea nitrogen (BUN) and creatinine tests measure kidney function by detecting waste products that kidneys normally remove from the blood. Chronic renal failure involves a slow loss of kidney function over time which can lead to end-stage renal disease requiring dialysis or transplant if left untreated. Common causes are diabetes and high blood pressure. Intermittent peritoneal dialysis is a dialysis procedure used to correct fluid/electrolyte imbalances or remove waste when kidneys fail.

Dialysis : Haemodialysis and Peritoneal dialysis
This document discusses dialysis, which is a process used to purify the blood of patients with kidney failure. There are two main types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis involves connecting the patient's blood to an external dialysis machine via surgically placed vascular access points, allowing diffusion and ultrafiltration to remove waste and excess fluid across a semi-permeable membrane. Peritoneal dialysis uses the peritoneum in the abdomen as the membrane, with dialysate fluid infused via a catheter to filter the blood. Both types of dialysis aim to replicate the waste removal normally done by functioning kidneys. Common problems with long-term dialysis include hypotension,

Kidney dialysis is a treatment for kidney failure that involves removing waste and excess water from the blood. There are two main types - hemodialysis which uses a dialysis machine to filter the blood outside the body, and peritoneal dialysis which uses the lining of the abdominal cavity. The dialysis machine works via diffusion and ultrafiltration across a semi-permeable membrane, allowing toxins and water to pass out of the bloodstream and be replaced by clean dialysate fluid. Researchers are developing wearable artificial kidneys to allow for more continuous dialysis treatment and improved patient mobility and quality of life.

Haemodialysis is a therapy that filters waste and balances electrolytes from the body through a semipermeable membrane. During haemodialysis, blood is pumped from the body through an artificial kidney called a dialyzer which cleans the blood before returning it. The average treatment lasts 3-4 hours and occurs weekly. The dialyzer contains thousands of tiny hollow fibers that act as semipermeable membranes, allowing waste to pass through into the dialysate solution which is then flushed out while balancing electrolytes in the blood. Preparing vascular access through an arteriovenous fistula or graft is important for efficient blood flow during haemodialysis treatments.
Dialysis
Continuous renal replacement therapy (CRRT) provides continuous dialysis treatment for patients with acute renal failure who cannot tolerate traditional intermittent hemodialysis. CRRT works around the clock to provide stable therapy without dangerous electrolyte and hemodynamic changes. There are various CRRT methods that differ in complexity, including continuous venovenous hemodialysis (CVVHD) where blood is pumped through a hemofilter to remove waste and fluids. CRRT requires vascular access via a catheter and uses pumps, hemofilters, replacement fluids, and dialysate to continuously clean and filter the blood. Nursing responsibilities for CRRT include monitoring vitals, equipment, lines, medications, schedules, and managing complications.

Dialysis is the artificial process of eliminating waste (diffusion) and unwanted water (ultra filtration) from the blood.
Dialysis is a procedure that cleans and filters the blood. It rids the body of harmful wastes and extra salt and fluids. It also controls blood pressure and helps our body keep the proper balance of chemicals such as potassium, sodium, and chloride.
Dialysis is a Greek word meaning "loosening from something else".

Hemodialysis,
This document discusses kidney failure treatment options including hemodialysis, peritoneal dialysis, and transplantation. Hemodialysis and peritoneal dialysis are dialysis techniques that use filters or the peritoneal membrane to remove waste and excess fluid from the blood. Kidney transplantation is usually the best long-term treatment but demand for donors exceeds supply.
Dialysis.
Dialysis is a treatment for people whose kidneys are failing. When you have kidney failure, your kidneys don't filter blood the way they should. As a result, wastes and toxins build up in your bloodstream. Dialysis does the work of your kidneys, removing waste products and excess fluid from the blood
Hemodialysis
Hemodialysis is a treatment to filter wastes and water from your blood; In hemodialysis, the blood is cleaned outside the body using a dialysis machine and then sent back into the body.
Hemodialysis is a treatment to filter wastes and water from your blood, as your kidneys did when they were healthy. Hemodialysis helps control blood pressure and balance important minerals, such as potassium, sodium, and calcium, in your blood.
Hemodialysis is one way to treat advanced kidney failure and can help you carry on an active life despite failing kidneys.
Mechanism of Hemodialysis:
Hemodialysis is a procedure by which waste products and excess water are removed from a patient’s blood. This is done by directly removing blood from the patient’s circulation, passing it through the dialysis filter, and then returning it directly back into the circulation.
Apparatus needed:
Dialyzer or dialysis filter
Dialysate (dialysis solution)
Tubing for transport of blood and dialysate
Machine that powers and monitors the filtration
Hemodialysis has 5 main steps which are as follows:
1.Two sets of tubing are connected to the patient’s dialysis access:
Connected directly to central venous catheter
Two needles inserted into AVF/AVG and taped down
2. Azotemic blood pumped from patient into dialysis filter
3. Dialysis filter removes toxins primarily through diffusion:
Dialysis filter is a plastic cylinder filled with thousands of tiny individual tubes composed of the filtering material.
Blood flows through the inside of the tiny tubes in one direction.
Dialysis fluid (dialysate) flows on the outside of the tiny tubes (but still within the single plastic cylinder that contains them) in the opposite direction.
The opposing directions of blood and dialysate result in maximal concentration gradients that drive the diffusion of toxins:
Known as “countercurrent” mechanism
Also results in correction of electrolyte/acid–base abnormalities via diffusion.
4. Dialysis filter removes excess water from the blood through ultrafiltration.
Suction force is applied by the dialysis machine across the dialysis filter.
Water is pulled from the blood side into the dialysate side.
5. Clean blood and waste-filled dialysate exit the dialysis filter.
Clean blood is pumped back into the patient’s Circulation.
Waste-filled dialysate is disposed of (including the excess water from the patient’s body that was removed during ultrafiltration).

Dialysis
Dialysis is a technique used to remove waste and excess fluid from the blood when the kidneys are failing. It works by using a semi-permeable membrane to allow substances to move from the blood into a dialysis solution. The main types of dialysis are hemodialysis, which uses a machine to filter blood outside the body, and peritoneal dialysis, which uses the peritoneal membrane in the abdomen. Proper care of dialysis access sites and following treatment protocols are important for patient safety and health.
Dialysis ppt
Dialysis is a process used to remove waste and excess water from the blood when the kidneys fail. It works through diffusion, osmosis, and filtration across a semi-permeable membrane. There are two main types of dialysis: hemodialysis, which cleanses the blood directly using an artificial kidney machine, and peritoneal dialysis, which uses the peritoneal membrane in the abdomen as a filter. Both aim to maintain fluid, electrolyte, and acid-base balance as well as remove toxins when the kidneys are unable to do so properly. Dialysis is crucial for survival in cases of both acute and chronic kidney failure.

Dialysis
Kidneys normally remove waste and regulate fluids and chemicals in the body. Kidney failure occurs when the kidneys fail to function properly. Dialysis is a treatment that artificially performs the kidneys' functions through diffusion and filtration across a semipermeable membrane. There are two main types of dialysis - hemodialysis which uses an external machine to filter blood, and peritoneal dialysis which uses the peritoneal membrane in the abdomen. Both treatments require vascular access or catheter placement and frequent sessions to sustain life for those with kidney failure.
Hemodialysis: management of chronic kidney disease
Hemodialysis is a mechanical process of removing waste products (toxic nitrogenous substances) and replacing essential substances by the process of diffusion and removal of excess water from body by the process of osmosis by means of artificial kidney (made with modified cellulose or synthetic) through semi-permeable membranes.
Introduction
This document provides information about hemodialysis machines. It discusses how hemodialysis machines work by pumping blood and dialysate through a dialyzer to remove waste and fluid from the bloodstream. The main components of hemodialysis machines are the water system, which purifies water used in dialysate, and the dialyzer, which contains hollow fibers that allow diffusion and osmosis across a semipermeable membrane. Hemodialysis machines must meet various technical specifications to safely and effectively perform hemodialysis treatments.
high-flux.pptx
The document discusses high flux hemodialysis. It notes that high flux dialyzers have larger surface areas and more permeable membranes than low flux dialyzers, allowing for more efficient removal of waste products including larger molecules. Some studies have found high flux dialysis improves removal of substances like lipids and proteins, while others have found no significant impact on molecules like homocysteine. The choice between high flux and low flux depends on the individual patient's condition and dialysis needs.

- 1. Options for Kidney Failure Patient. Kidney Transplant Definition- Kidney transplant: Replacement of a diseased, damaged, or missing kidney with a donor kidney. Procedure- During the transplant operation, the kidney recipient is typically under general anesthesia and administered antibiotics to prevent possible infection. A catheter is placed in the bladder before surgery begins. An incision is made in the flank of the patient, and the surgeon implants the kidney above the pelvic bone and below the existing, non-functioning kidney by suturing the kidney artery and vein to the patient's iliac artery and vein. The ureter of the new kidney is attached directly to the kidney recipient's bladder. Once the new kidney is attached, the patient's existing, diseased kidneys may or may not be removed, depending on the circumstances surrounding the kidney failure. Barring any complications, the transplant operation takes about three to four hours.

- 3. Dialysis Definition- Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. Diffusion describes a property of substances in water. Substances in water tend to move from an area of high concentration to an area of low concentration. Blood flows by one side of a semi-permeable membrane, and a dialysate, or special dialysis fluid, flows by the opposite side. A semipermeable membrane is a thin layer of material that contains various sized holes, or pores. Smaller solutes and fluid pass through the membrane, but the membrane blocks the passage of larger substances (for example, red blood cells, large proteins). How Dialysis Works- Hemodialysisis the most common form of dialysis. It involves being connected to a dialysis machine, sometimes called an artificial kidney, where the patient's blood is extracted from their body, passed through the machine, cleaned and returned. The process uses a fluid called dialysate to remove the waste from the blood. Both the blood and the dialysate are pumped through the machine. The blood never touches the dialysate. Waste is passed from the blood to the dialysate through a series of membranes within the machine. The dialysate removes the waste and the clean blood returns to the body.
