What is acute renal failure?

Frequently Asked Questions
quot;Renal" means related to the kidneys. "Acute" means sudden. So acute renal failure means the kidneys have failed suddenly, often due to a toxin (a drug allergy or poison) or severe blood loss or trauma. Dialysis is used to clean the blood and give the kidneys a rest. If the cause is treated, the kidneys may be able to recover some or all of their function.

Can BYETTA be used in patients with renal insufficiency or end-stage renal disease?

Byetta (exenatide) for Type 2 Diabetes Safety
BYETTA is not recommended for use in patients with end-stage renal disease or severe renal impairment (creatinine clearance <30mL/min). In patients with end-stage renal disease receiving dialysis, single doses of BYETTA 5 mcg were not well tolerated due to gastrointestinal side effects. For complete safety profile and other important prescribing considerations, see the full Prescribing Information.

What can be done so that renal calculi disappear?

FAQ
Except in the case of the uric acid calculi that can be dissolved in vivo (inside the organism) by means of urine alkalinization, no medication to dissolve them in vivo exists. However fragmentation inside the organism can be done facilitating the expulsion of smaller size fragments. On the other hand, it is important to discover the causes that have induced the calculi formation, in order to correct and to prevent the appearance of new episodes.

What about patients with renal insufficiency?

profaq
In a cross-study comparison, celecoxib AUC was approximately 40% lower in patients with chronic renal insufficiency (GFR 35-60 ml/min) than that seen in subjects with normal renal function. No significant relationship was found between GFR and celecoxib clearance. Patients with severe renal insufficiency have not been studied.

What is the formula for clearance tests?

Highlights and FAQ's
C = U/P X V C = plasma clearance, U = Urine concentration, P = plasma concentration and Volume is the volume of urine in milliliters per minute. The units of the substance in the urine and blood have to be the same. This formula works for the "average" body surface.

What exactly is renal failure? Can my pet have renal failure and still be alive?

Menu Foods pet food recall - FAQ from The Animal Medical Cen...
Renal failure means that the kidneys are not working to remove toxins from your pet's body. Your pet can be alive and be in renal failure. Most of the time, the symptoms of renal failure are decreased appetite, lethargy, vomiting, maybe diarrhea; increased water consumption, increased or decreased urine production. In cats that use a litter box, you may notice a need to change the box more often than usual. Dogs may ask to go outside more often or the well housebroken dog may have accidents.
Related Questions

What are the risks of suffering renal lithiasis in repeated occasions, without painful renal colics?

FAQ
The presence of calculi in kidney can produce injuries in the uroepithelium, although the extension of these injuries will depend on, to certain extend, the location in the renal cavities. Those injuries could induce new crystallization focuses, generating more calculi in this way.

FAQ
There are many types of renal calculi and each one has different formation causes. However, in general there is an unfortunate combination of several factors.

What is the less painful form of expelling renal calculi?

FAQ
When renal calculi elimination doesn't take place spontaneously, non invasive techniquescan be used, as shock waves extracorporeal lithotripsy (SWEL), percutaneous nephrolithotomy, etc. avoiding open surgery. However in some cases the classic surgery is unavailable. Yet, despite evident importance of calculi elimination processes, the affected patient should be more interested avoiding the episode repetition.

What is the most appropriate diet so that renal calculi is not generated?

FAQ
Due to the existence of different types of renal calculi, the most appropriate diet depends on the type of calculi formed, because for each different type there are different generation causes. However, in general, diets should be balanced, not excessively vegetarian nor meat rich. A high consumption of liquids is always advisable (preferably not carbonic drinks), although in some cases, such as uric acid lithiasis,) their consumption is recomendable.
Related Questions

Is water effective to eliminate renal sands?

FAQ
Higher consumption of water implies higher diuresis (that is a higher urinary volume than normal) which induces a higher flow and it allows haulage of renal sands, by diluting the urine (diminishing the salts concentration). However, in the case of a considerable size renal calculi that can not be expelled spontaneously, the increase of diuresis will not contribute to its elimination.

What can one do to avoid the recurrence of calcium oxalate renal lithiasis?

FAQ
COM calculi (a) are usually associated to a deficit of inhibitors of the crystallization, to some alterations of renal epithelium, to alterations of urinay pH and the presence of organic matter in urine. COD calculi (b) are usually associated to an excess of urinary calcium excretion (hypercalciuria) that gives place to high urinary calcium concentrations. Prevention depends on calculus type and on the urinary parameters alterated.

HOW IS CALCITRIOL AFFECTED BY CHRONIC RENAL DISEASE?

Calcitriol - Frequestly Ased Questions
During chronic renal failure the number of functioning renal tubules becomes progressively decreased. Because the tubular cells making calcitriol are lost, its synthesis becomes limited. An even greater limitation on calcitriol formation is the powerful inhibition of the 1-hydroxylation of 25-hydroxyvitamin D by high levels of blood phosphorus. As serum phosphorus levels increase, following reduced glomerular filtration rates, concentrations are achieved which block synthesis of calcitriol.

HOW OFTEN DOES RENAL FAILURE CAUSE SECONDARY HYPERPARATHYROIDISM?

Calcitriol - Frequestly Ased Questions
Hyperparathyroidism occurs in most dogs and cats with chronic renal failure. Its extent is proportional to the increases of serum creatinine, and is quite directly related to the extent of uremic hyperphosphatemia. Serum phosphorus (Pi) is elevated primarily because of failure of renal excretion but its level is also affected by dietary intake, use of intestinal phosphorus binders and to some degree by the extent of PTH-mediated bone resorption.
Related Questions

HOW DOES RENAL FAILURE CAUSE HYPERPARATHYROIDISM?

Calcitriol - Frequestly Ased Questions
The current state of knowledge of calcitriol-PTH relationships allows better interpretation of the classical views that the genesis of hyperparathyroidism in chronic renal failure is due to (a) hypocalcemia, (b) increased skeletal resistance to PTH, and/or (c) increased parathyroid gland set point for calcium suppression of PTH secretion.

My renal unit seems to have a longer median cold ischaemic time than other units. Does this matter?

Organ Donation - Cambridge International Academy
There is some variation in the CIT between units and there will also be a difference between transplants in the same unit. There is evidence that a CIT of over 20 hours affects outcomes and if the CIT is very long for a particular kidney, the transplant team will discuss this with the patient.
