Good but not perfect results can be obtained with many types of catheters. Convincing data demonstrating superiority of one catheter over another are not available. What is the comparative cost of these catheters? The straight Tenckhoff catheter remains the least expensive at $42.50 (Quinton Instrument Company). Until a large randomized trial is done demonstrating a clear superiority of another catheter, we will continue to use the straight double-cuff Tenckhoff catheter.
