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.
