Some issues Dr. John K. Maesaka, MD can help you with:

Acute Kidney Failure

Kidney failure is when 80% to 90% of kidney function is lost. Kidney failure is also referred to as end-stage renal disease (ESRD). Kidneys are critical to human health, essentially acting as the body's built-in filtration system. When the kidneys can no longer function effectively, waste can accumulate in the blood and concentrations of nutrients can become unbalanced, impairing the body from performing critical functions. For example, if the kidneys do not regulate levels of potassium, the heart may develop arrhythmias (irregular rhythm) or even go into cardiac arrest.

Kidney failure may be caused by a number of health conditions that slowly damage and weaken the kidneys, such as:

Diabetes
High blood pressure
Urinary tract problems
Excessive alcohol consumption
Persistent and severe dehydration
Lupus
Acute kidney injury (AKI)

High blood pressure and diabetes are the most frequently observed causes of kidney failure. However, these conditions typically take years to develop into kidney failure and might escape notice during that time.

Symptoms of kidney failure include:

Difficulty sleeping
Fatigue
Reduced appetite
Weight loss
Edema (water retention)
Ankle and foot swelling
Anemia
Itching
Muscle cramps

No cure currently exists for kidney failure; however, medical treatment can permit people to live healthy and long lives. A nephrologist (kidney doctor) determines the most effective treatments for patients with kidney failure.

Dialysis is a well-known treatment for kidney failure that uses a machine to filter and clean waste from the blood. Patients attend regular dialysis sessions to replace their lost kidney function. Some patients with kidney failure are unable to survive without having dialysis every few days.

More advanced kidney failure may be treated by kidney transplant surgery. Deceased donor kidney transplant surgery provides kidney failure patients with a healthy kidney from a recently deceased person. Living donor kidney transplant surgery provides a kidney from a donor who is still alive. As most people have two kidneys, kidney failure patients' relatives or friends may offer to donate one of their kidneys. Kidney transplants can dramatically improve kidney function and lower or eliminate the need for dialysis.

People with kidney failure are advised to eat a nutritious diet, monitor and lower blood pressure, and to best manage diabetes. Exercise and a tobacco-free lifestyle may also help patients with kidney failure.

Kidney Stones

Kidney stones are hard deposits that form in the kidneys, made up of minerals that are normally present in urine. They can vary in size, from as small as a grain of sand to as large as a nickel, occasionally even larger. Sometimes they lodge in the kidney, and sometimes they break free and make their way out through the urinary tract, which can be extremely painful.

Kidney stones can be smooth or jagged and are yellow to brown in color. They are mostly comprised of the minerals calcium, oxalate, and phosphorus. Examining the stones to see what they are made of can show what caused the stone to be formed in the first place. For example, a stone made of mostly calcium, which is the most common type, can happen any time the urine becomes too concentrated due to dehydration or a blockage in the kidney. A uric acid stone forms when acid levels in the urine get too high, usually due to excessive consumption of animal protein such as meat and fish. A struvite stone is a sign of certain infections, and a cystine stone can be due to a genetic disorder that raises the risk of kidney stones.

The most common symptom of kidney stones is pain, either in the back or lower abdomen, or severe pain when urinating. There may also be blood in the urine. Treatment for kidney stones depends on how large the stone is. Very small stones can pass out of the body on their own, and they do not require treatment other than drinking adequate water and taking pain killers. Larger stones need to be broken apart and removed. The main treatment options are:

Shock wave lithotripsy, which uses sound wave vibrations to break apart the stone
Percutaneous nephrolithotomy, or the use of a very tiny tool (like a wire inserted through the back) to break apart and remove the stone
Ureteroscopy, a thin tube inserted through the urethra and bladder to the stone, where tiny tools can grasp the stone and remove

People who have had one kidney stone are at risk of developing another. To reduce this risk, patients are given instructions specific to the type of stone they developed. Generally the instructions will include drinking more water to dilute the urine, but it may also involve lowering sodium intake or eating less meat.
