Portable, less costly peritoneal dialysis shows no additional catheter risk factors
Date:3/3/2011

DALLAS March 3, 2011 Patients with end-stage renal disease who opt for peritoneal dialysis experience no greater risk of catheter infection than those who undergo hemodialysis, a retrospective study at UT Southwestern Medical Center has found.

Peritoneal dialysis is less costly, easier on the body and provides greater mobility than hemodialysis, the more common procedure in the U.S.

"Patients actually survive better on peritoneal dialysis, have a better quality of life and the procedure is cheaper," said Dr. Ramesh Saxena, associate professor of internal medicine at UT Southwestern and a senior author of the study, available online in the Journal of Vascular Access. "Factors such as obesity, age and previous abdominal surgeries should not be considered as barriers in selecting patients for peritoneal dialysis."

Peritoneal dialysis (PD) is the removal of waste fluids in end-stage kidney failure patients through a catheter placed in the abdominal cavity. PD is easier on patients because it mimics natural kidney function through a slower and continuous process of replenishing the body with healthy fluids. Peritoneal dialysis also affords greater flexibility for patients since the equipment is portable and can be self-administered.

Yet while 95 percent of end-stage renal disease patients end up on dialysis, most in the U.S. are referred to hemodialysis, which is administered through an access in the arm at a dialysis clinic.

Dr. Saxena said nephrologists in the U.S. do not receive enough training in peritoneal dialysis, though it is a common form of dialysis worldwide. UT Southwestern has one of the largest peritoneal dialysis clinics in the country, with up to 120 patients treated at a time, compared to an average of 20 patients at a typical hemodialysis clinic in the U.S.

"The myth is that peritoneal dialysis is seen as infectious and difficult to manage, but there has been no formal study on thes
