Some issues Dr. Michael Charles Chobanian, MD can help you with:

Dialysis

Dialysis is a procedure that replicates renal (kidney) function by filtering patients' blood. When kidneys do not work properly, waste can accumulate in the blood and unbalanced chemicals can impair the body's critical functions. In order to stay healthy, a person without proper kidney function must receive dialysis. There are two forms of dialysis treatment: hemodialysis and peritoneal dialysis. Both forms of dialysis are recurring treatments that in many cases last throughout the lifetime of the affected patient. Patients who briefly lose renal function may slowly reduce the frequency of dialysis sessions until their kidneys recover. However, most patients who start on dialysis remain on dialysis for the rest of their lives or until they receive a kidney transplant.

A number of conditions can worsen renal function and lead to end-stage or acute kidney failure. When kidneys fail (i.e. nearly 90 percent of their function is lost), dialysis is typically prescribed. Conditions that cause chronic kidney failure (eventually requiring dialysis) include:

Type 1 and 2 Diabetes
Pyelonephritis, recurring kidney infection
Glomerulonephritis, inflammation of the kidney's filtering parts
Polycystic kidney disease
Interstitial nephritis, inflammation of the kidney's tubules
High blood pressure
Vesicoureteral reflux, improper bladder emptying

For hemodialysis (the more common form of dialysis), a patient will visit a hospital or clinic and be connected to a dialysis machine by a needle attached to a tube that draws blood from the arm. The drawn blood is transferred to the dialysis machine, where it is filtered and separated until clean. Waste products from the blood pass into a fluid called dialysate, which is pumped out of the machine into a waste receptacle. The machine also measures and helps ensure the blood has the appropriate level of fluid, electrolytes, and pH. A tube delivers the cleaned blood back into the patient's body. A dialysis session like this will typically last for three to four hours, with a patient undergoing dialysis around three times per week.

A second method of dialysis is known as peritoneal dialysis. Unlike hemodialysis, peritoneal dialysis can be performed at home by oneself after an initial surgery. To start, a physician (generally a surgeon) will make a small incision in the lower abdomen and insert and surgically attach a catheter (thin tube). At home, the patient connects a pump to the abdomen catheter, delivering dialysate (dialysis fluid) from a bag hanging on a wheeled stand. This fluid enters the peritoneal cavity (greater abdomen area containing the stomach, liver, and intestines) and collects waste through osmosis, where waste in the blood moves across a membrane and into the dialysate. This process continues for several hours until the fluid concentration is equal between the blood and dialysate, at which point the fluid can be drained. The fluid can then be passed through a machine called a cycler, which removes waste and allows for the dialysate to be reused. This process is repeated about four times per day. Dialysis patients must limit the amount of fluid they consume prior to receiving dialysis and should also avoid eating salty foods. The cycler cannot filter more than a certain amount of waste products from the blood.

Kidneys are important organs, and dialysis treatments are vital for those with renal dysfunction. For many, dialysis is not so much a medical procedure but a part of their normal life.
