How Does Protein Get Into Urine
Protein gets into the urine if the kidneys arent working properly. Normally, glomeruli, which are tiny loops of capillaries in the kidneys, filter waste products and excess water from the blood.
Glomeruli pass these substances, but not larger proteins and blood cells, into the urine. If smaller proteins sneak through the glomeruli, tubules recapture those proteins and keep them in the body.
However, if the glomeruli or tubules are damaged, if there is a problem with the reabsorption process of the proteins, or if there is an excessive protein load, the proteins will flow into the urine.
Prognosis Of Chronic Kidney Disease
If chronic kidney disease is caused by a disorder that can be corrected and if that disorder has not been present for too long, then kidney function may improve when the causative disorder is successfully treated. Otherwise, kidney function tends to worsen over time. The rate of decline in kidney function depends somewhat on the underlying disorder causing chronic kidney disease and on how well the disorder is controlled. For example, diabetes and high blood pressure, particularly if poorly controlled, cause kidney function to decline more rapidly. Chronic kidney disease is fatal if not treated.
When the decline in kidney function is severe , survival is usually limited to several months in people who are not treated, but people who are treated with dialysis Dialysis Dialysis is an artificial process for removing waste products and excess fluids from the body, a process that is needed when the kidneys are not functioning properly.

However, even with dialysis, people with end-stage kidney failure die sooner than people their age who do not have end-stage kidney disease. Most die from heart or blood vessel disorders or infections.

Stages Of Chronic Kidney Disease
Chronic kidney disease occurs when one suffers from gradual and usually permanent loss of kidney function over time. This happens gradually, usually over months to years. Chronic kidney disease is divided into five stages of increasing severity. The term “renal” refers to the kidney, so another name for kidney failure is “renal failure.” Mild kidney disease is often called renal insufficiency.
With loss of kidney function, there is an accumulation of water, waste, and toxic substances in the body that are normally excreted by the kidney. Loss of kidney function also causes other problems such as anemia, high blood pressure, acidosis , disorders of cholesterol and fatty acids, and bone disease.
Stage 5 chronic kidney disease is also referred to as kidney failure, end-stage kidney disease, or end-stage renal disease, wherein there is total or near-total loss of kidney function. There is dangerous accumulation of water, waste, and toxic substances, and most individuals in this stage of kidney disease need dialysis or transplantation to stay alive.

Kidneys Clear From The Plasma
How much plasma do you have in your body?
Ill tell you. About 3 liters. In fact, the average woman has less than that.
It is from these 3 liters that kidneys filter their 150 liters daily. So the 3 liters of plasma are filtered over and over again 150/3 or 50 times a day. Of course, most filtrate is taken back, so the plasma volume stays constant. You might think the whole process is silly filter it, and put it back in.
But taken back is not simple. Some molecules are taken back only partly, some not at all. Some almost entirely. The kidney cells that line the nephron control this for each molecule. That selection of what is to go and what is to stay determines innumerable blood concentrations. It is the very quintessence of what it means to be a kidney.
Filtration itself is just about water, however, so what does it matter that 99% of filtered water is taken back? It is that the water is taken back but what was in that water and destined for removal was not equally taken back. To the extent that water is taken back and crystallizing salts are taken back less than enough, kidneys will make crystals.
In that simple phrase lies much of calcium stone formation.

What Happens If You Have Kidney Disease
Kidney disease can be treated. The sooner you know you have kidney disease, the sooner you can get treatment to help delay or prevent kidney failure. Treating kidney disease may also help prevent heart disease.
Treatment goals are to:
- If you smoke, take steps to quit.
- Take medicines the way your provider tells you to.
What Happens When Chronic Kidney Disease Or Another Serious Condition Is Diagnosed Or Suspected
A doctor who suspects kidney disease would repeat the urine test three times over three months. If the samples test positive for proteins each time, the patient likely has kidney disease. The earlier the diagnosis, the more chance doctors have to slow the disease and stop it from progressing.
Additional tests might include:

Can Children Get Kidney Stones
Kidney stones are found in children as young as 5 years. In fact, this problem is so common in children that some hospitals conduct ‘stone’ clinics for pediatric patients. The increase in the United States has been attributed to several factors, mostly related to food choices. The two most important reasons are not drinking enough fluids and eating foods that are high in salt. Kids should eat less salty potato chips and French fries. There are other salty foods: sandwich meats, canned soups, packaged meals, and even some sports drinks. Sodas and other sweetened beverages can also increase the risk of stones if they contain high fructose corn syrup.

Characteristics Of Study Patients
There were 3089194 eligible patients without ESRD at baseline . Of these, 1954836 had outpatient serum creatinine measurements and were included in analyses of new stage 3b5 chronic kidney disease and sustained doubling of serum creatinine level from baseline. The characteristics of the study patients with and without kidney stone episodes are shown in table 1. Patients with kidney stones were older and more likely to be men, to have had hypertension, and to have a history of kidney stones.

Results were similar in analyses that examined the risk of ESRD associated with kidney stones in strata defined by the intersection of age and sex . Specifically, the magnitude of the excess risk remained greater in female and younger participants, and the risk of all three adverse renal outcomes was significantly increased in the four mutually exclusive groups formed by the intersection of age and sex.

Using patients as their own internal controls, it was demonstrated that 80% of patients lying in a lateral decubitus position with the left side down had demonstrably increased renal perfusion in the dependent kidney and 90% of patients who lay with their right side down had similar increased perfusion.
Is There A Diet For Chronic Kidney Disease
Chronic kidney disease is a disease that must be managed in close consultation with a doctor. Self-treatment is not appropriate.
- There are, however, several important dietary rules one can follow to help slow the progression of kidney disease and decrease the likelihood of complications.
- This is a complex process and must be individualized, generally with the help of a health care practitioner and a registered dietitian.
The following are general dietary guidelines:
- Protein restriction: Decreasing protein intake may slow the progression of chronic kidney disease. A dietitian can help one determine the appropriate amount of protein.
- Salt restriction: Limit to 2 to 4grams a day to avoid fluid retention and help control high blood pressure.
- Fluid intake: Excessive water intake does not help prevent kidney disease. In fact, the doctor may recommend restriction of water intake.
- Potassium restriction: This is necessary in advanced kidney disease because the kidneys are unable to remove potassium. High levels of potassium can cause abnormal heart rhythms. Examples of foods high in potassium include bananas, oranges, nuts, avocados, and potatoes.
- Phosphorus restriction: Decreasing phosphorus intake is recommended to protect bones. Eggs, beans, cola drinks, and dairy products are examples of foods high in phosphorus.
Other important measures that a patient can take include:

Correction Of Phosphate Balance
If you have stage four or five kidney disease, you can get a build-up of phosphate in your body because your kidneys cannot get rid of it. Phosphate is a mineral that, with calcium, makes up most of your bones. Phosphate is obtained through diet, mainly dairy foods. The kidneys usually filter out excess phosphate. If phosphate levels rise too much, it can upset the normal calcium balance of the body. This can lead to thinning of the bones and furring of the arteries.
You may be asked to limit the amount of phosphate in your diet. Foods high in phosphate include red meat, dairy produce, eggs and fish. Your GP or dietitian should be able to advise you about how much phosphate you can eat. However, there is no advantage in reducing your intake of these foods unless you have a raised phosphate level. Always ask a healthcare professional before changing your diet.
If reducing the amount of phosphate in your diet does not lower your phosphate level enough, you may be given medicines called phosphate binders. These medicines bind to the phosphate in the food inside your stomach and stop it from being absorbed into your body.
To work properly, phosphate binders must be taken just before meals. The most commonly used phosphate binder is calcium carbonate, but there are also alternatives that may be more suitable for you.
The side effects of phosphate binders are uncommon but include:
- itchy skin

Why Do I Need A Glomerular Filtration Rate Test
The GFR test can indicate how well your kidneys are functioning. Your doctor may order the test if you have symptoms related to kidney disease or if they want to test the effectiveness of a particular treatment. According to the American Association for Clinical Chemistry, examples of kidney disease symptoms include:
- unexplained body swelling
- difficulty urinating
- mid-back pain
Early intervention is vital to preventing further kidney damage. Your doctor may recommend a GFR test if youre taking medications that can affect your kidney function or if you have any of the following conditions:
- polycystic kidney disease
- kidney failure
If youve been diagnosed with kidney disease, the GFR test can help determine how well your kidneys are functioning.
If you have a family history of kidney disease, your doctor may want to run a GFR test to get a sense of the current state of your kidneys.
Let Kidney Stones Pass
Stones typically take several weeks to a few months to pass, depending on the number of stones and their size. Over-the-counter pain medications, like ibuprofen , acetaminophen , or naproxen , can help you endure the discomfort until the stones pass. Your doctor also may prescribe an alpha blocker, which relaxes the muscles in your ureter and helps pass stones quicker and with less pain.
If the pain becomes too severe, or if they are too large to pass, they can be surgically removed with a procedure called a ureteroscopy. Here, a small endoscope is passed into the bladder and up the ureter while you are under general anesthesia. A laser breaks up the stones, and then the fragments are removed.

Symptoms Of Chronic Kidney Disease
Symptoms usually develop very slowly. As kidney failure progresses and metabolic waste products build up in the blood, symptoms progress.
Mild to moderate loss of kidney function may cause only mild symptoms, such as the need to urinate several times during the night . Nocturia occurs because the kidneys cannot absorb water from the urine to reduce the volume and concentrate it as normally occurs during the night.
As kidney function worsens and more metabolic waste products build up in the blood, people may feel fatigued and generally weak and may become less mentally alert. Some have a loss of appetite and shortness of breath. Anemia also contributes to fatigue and generalized weakness.
The buildup of metabolic waste also causes loss of appetite, nausea, vomiting, and an unpleasant taste in the mouth, which may lead to undernutrition and weight loss. People with chronic kidney disease tend to bruise easily or bleed for an unusually long time after cuts or other injuries. Chronic kidney disease also diminishes the bodys ability to fight infections.

What Is The Evidence Behind Reporting Of The Egfr
As a result of the automatic reporting of eGFR, the clinical detection of kidney disease has significantly increased in the community.
In 2004, a clinical study involving 324 outpatients was performed to evaluate the effect of automatic laboratory reporting of eGFR with each request for serum creatinine. The effects on detection of chronic kidney disease were assessed. This automatic reporting was combined with education aimed at doctors involved in the study. The presence of an eGFR value, in conjunction with education significantly increased the detection of chronic kidney disease from 22.4% to 85.1% of patients. However, further research needs to be conducted regarding the significance and longer term outcomes resulting from this improved detection of chronic kidney disease. Last but not least, if the eGFR is normal, but there are other abnormal investigation results , the GFR should be calculated.

Can Kidney Stones Lead To Chronic Kidney Disease
If you or someone you know has had a kidney stone before, you probably heard them describe the excruciating pain. What may start out feeling like a stomachache or some lower back pain can quickly become unbearable as your body tries to pass the stone.
Though painful, a kidney stone typically does not cause damage. However, kidney stones can be a sign of other health issues.
More people are getting kidney stones, which is cause for concern because of the factors that contribute to kidney stones and what can happen if kidney stones keep recurring, said Prince Mohan, M.D., medical director of Transplant Nephrology at Geisinger.
Typically, any waste that builds up in the kidneys is dissolved in the liquid that passes through them. But when there is a high level of minerals or salt and too little liquid, kidney stones begin to form. Usually, kidney stones that stay in the kidney arent noticeable.
The pain is a result of the kidney stone beginning to move from a kidney to the bladder through a tube called the ureter.
Most people dont know they have a kidney stone until they begin to feel severe pain in the side or abdomen, nausea, or if their urine is pink or red, said Dr. Mohan. They may be diagnosed in the emergency department after experiencing severe pain.
Having one kidney stone increases the risk of developing another one, said Dr. Mohan. This also increases the risk of chronic kidney disease and kidney failure.
