Abstract
A functioning peritoneal access is crucial to the success of peritoneal dialysis. We report retrospective analysis of our experience using 44 Tenckhoff and 23 column disc, double-cuff, catheters in 46 patients receiving peritoneal dialysis. Postoperative care was identical in both groups. Both catheter groups were comparable with regards to age, sex, obesity and prior abdominal surgery. Catheter removal due to drainage failure was significantly greater with the column disc than the Tenckhoff catheters (22% vs 5%, p = 0.04). In addition, 39% of column disc catheters compared to 11% Tenckhoff catheters were removed as a result of therapy resistant peritonitis (p = 0.011). Furthermore, there was a greater incidence of peritonitis with the column disc than with the Tenckhoff catheters at the end of the first year (71% vs 42%, p < 0.01). There was no difference between the two groups with respect to other complications, such as pericatheter leak, catheter infections, catheter cuff-extrusion or hernia. Our experience indicates that the column disc catheter is associated with higher complication rates and does not offer any advantage over the Tenckhoff catheter
