  • Title: Peritoneal dialysis access: prospective randomized comparison of the Swan neck and Tenckhoff catheters.
    Author: Eklund BH, Honkanen EO, Kala AR, Kyllönen LE.
    Journal: Perit Dial Int; 1995; 15(8):353-6. PubMed ID: 8785234.
    Abstract:
    OBJECTIVE: To examine the impact of peritoneal catheter configuration on mechanical complications, catheter survival, probability of episodes of peritonitis, and probability of exit-site infections associated with the use of catheters for continuous ambulatory peritoneal dialysis (CAPD). DESIGN: Prospective randomized trial. SETTING: CAPD unit in one university hospital, serving a population of 1.2 million. PATIENTS: Forty consecutive patients requiring their first dialysis catheter for future CAPD were randomized to receive either a two-cuff permanently bent Swan neck catheter or a two-cuff straight Tenckhoff catheter. The skin exit was downward-directed in the Swan neck group and upward-directed in the Tenckhoff group. RESULTS: Dialysate leak, catheter migration, or tunnel infection did not occur in any of the patients. Three outer cuff extrusions needing cuff shaving occurred, all in the Tenckhoff group (p = 0.1). No significant differences could be demonstrated in catheter survival at 2 years, probability of episodes of peritonitis, or probability of exit-site infections. CONCLUSION: Catheter configuration did not influence the catheter-related mechanical or infectious complications, and equally good results were obtained with both catheter types studied.
