Straight Versus Coiled Peritoneal Dialysis Catheter for Peritoneal Dialysis Patients
Straight Versus Coiled Peritoneal Dialysis Catheter for Peritoneal Dialysis Patients
This study compares the result of straight versus coiled Tenckhoff catheters for peritoneal
 dialysis patients. Recent meta-analysis of the peritoneal dialysis catheter type was in favor
 of straight catheters. The effects of straight versus coiled peritoneal dialysis catheters,
 however, are unclear. The investigators design an adequately powered randomized controlled
 study to evaluate the two types of double-cuffed peritoneal dialysis catheters. The primary
 objective is to assess whether straight peritoneal dialysis catheters can reduce the risk of
 catheter dysfunction that requires intervention. The investigators estimate that they would
 need to enroll 132 incident peritoneal dialysis patients in each group for the study to have
 80% power to detect a difference between 7% and 15% in the primary endpoint of catheter
 dysfunction requiring intervention.
The objective of the present study is to evaluate the a priori hypothesis that straight
 peritoneal dialysis catheters would improve the treatment outcomes of peritoneal dialysis.
 The early and late catheter complications, as well as catheter survival, will be compared
 between peritoneal dialysis patients who are randomized to straight and coiled Tenckhoff
 catheters.
