What Is Dialysis?

When your kidneys fail to function properly, waste products that are normally cleared by the kidneys build up in your bloodstream. As the levels of these toxins rise, you may begin to feel sluggish and nauseated. If left untreated, kidney failure can result in seizures, coma, and premature death. Dialysis removes these waste products when kidneys can no longer do so. There are two basic types of dialysis therapy:


Hemodialysis circulates your blood from a tube in your arm through a machine to filter out toxins. After the hemodialysis machine has cleaned the "sick" blood of waste products, the "healthy" blood is returned to the patient. Using one of several types of vascular access devices (such as a catheter, AV fistula, AV graft), we are able to perform hemodialysis for three to four hours a day, three days a week.

The Mount Sinai Kidney Center offers two convenient services for hemodialysis: The bright, spacious new Mount Sinai Kidney Center at East River Plaza, which provides therapy for adult outpatients, and the B1 Unit, which provides therapy for adult and pediatric inpatients and outpatients at Mount Sinai.

Home Dialysis Programs

Peritoneal dialysis (PD) filters blood by flowing a cleansing solution into your abdominal cavity through a surgically-inserted catheter, then draining the solution and toxins a few hours later. PD therapy may be performed several times a day or overnight while the patient is asleep.

The Mount Sinai Kidney Center offers Peritoneal Dialysis (PD) and Home Hemodialysis (HHD) in its Home Dialysis Program, which equips and trains patients to perform peritoneal dialysis on their own.
