Because of their vital functions such as filtering wastes and fluids from the bloodstream, kidneys are essential for human survival. Dialysis is a treatment that filters the blood for the body when the kidneys fail. There are two types of dialysis:

  • Hemodialysis uses a machine, often referred to as an artificial kidney, to do the work.
  • Peritoneal dialysis uses the lining of the abdomen to filter the blood.

In addition to working with patients needing peritoneal dialysis, the acute dialysis unit at GW Hospital has eight Fresenius K series machines and two Cobe-Spectra Plasmapheresis machines which offer patients several dialysis options: 

  • Conventional Hemodialysis for stable patients with acute and chronic kidney failure
  • Continuous Renal Replacement Therapy (CVVH) is provided for acute and critically ill patients who cannot tolerate regular hemodialysis
  • Slow Extended Daily Dialysis (SLEDD) is offered as a bridge between CVVH and regular hemodialysis as well as to selected patients who are critically ill and unstable
  • Therapeutic Plasmapheresis is offered for renal and non-renal disease by well-trained clinicians, nurses, and technicians


More than 30,000 Americans suffer from kidney cancer each year and many more have suspicious growths on their kidneys requiring surgical removal or biopsy, known as nephrectomy. Kidney cancer, kidney disease, or infection can result in kidney failure. If one or both kidneys fail to operate properly, a patient may need to undergo chronic dialysis treatment or the surgical transplantation of a healthy kidney in order to sustain life. 

In a partial nephrectomy, only the diseased or infected portion of the kidney is extracted. Radical nephrectomy involves the removal of the entire kidney, a section of the tube leading to the bladder (ureter), the adrenal gland, and the fatty tissue surrounding the kidney. A simple nephrectomy requires the removal of the kidney and a section of the attached ureter.
