Outcomes of peritoneal dialysis catheter reinsertion: does the cause of initial removal matter?

In this study, we aimed to compare patient and technique survival between the patients, in whom peritoneal dialysis (PD) catheter was removed due to severe peritonitis and then it was reinserted, and those, in whom PD catheter was removed due to non-peritonitis causes and then it was reinserted.

Sixty-two patients, in whom PD catheter was reinserted surgically, were retrospectively analyzed in this cohort study. Group 1 consisted of 27 patients in whom PD catheter was removed due to severe peritonitis, whereas Group 2 consisted of 35 patients in whom PD catheter was removed due to non-peritonitis causes.

There was no significant difference between Group 1 and Group 2 in terms of the estimation of overall patient survival [43 months (95 % CI 43.6-83.7) versus 80 months (95 % CI 52.8-107.3, p 0.362]. Similarly, there was no significant difference between Group 1 and Group 2 in terms of the estimation of overall technique survival [82 months (95 % CI 0-166.0) versus 31 months (95 % CI 9.7-52.3), p 0.346].

Our results suggest that there was no significant effect of causes of PD catheter removal (peritonitis vs. non-peritonitis) on the outcomes of PD treatment.
