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. PATIENTS: Forty consecutive patients requiring a dialysis catheter for future CAPD were randomized to receive either a single-cuff straight Tenckhoff catheter or a permanently bent single-cuff Swan neck catheter. The skin exit was upward-directed in the Tenckhoff group and downward-directed in the Swan neck group. RESULTS:Dialysate leak occurred in one patient and symptomatic catheter tip migration in 3 patients with the Tenckhoff catheter but in none with the single-cuff Swan neck catheter (p = 0.5, p = 0.12). No significant differences in catheter survival at 2 years, probability of episodes of peritonitis, or probability of exit-site infections could be demonstrated. CONCLUSION: Catheter configuration did not influence the catheter-related mechanical or infectious complications. We were unable to demonstrate any advantage of the newer, permanently bent single-cuff Swan neck catheter over the conventional straight type.
