Abstract
Purpose
There is a paucity of data on the prognosis for patients returning to peritoneal dialysis (PD) after a failed transplant. PD has an advantage over hemodialysis in preserving residual renal function, which is associated with better outcomes.
Methods
We have reviewed the electronic charts of patients on PD in a tertiary academic hospital for the last 8 years. We have compared technique survival, peritonitis-free survival, and residual diuresis in two groups: patients with graft failure which returned to PD (PD-KTx, N = 18) and patients starting PD for other causes (PD-not KTx, N = 163).
Results
The median follow-up was similar between groups [42(16,71) in PD-not KTx vs. 48(22,90) months in PD-KTx, p = 0.293]. Kaplan–Meier survival comparing PD-KTx and PD-not KTx showed no difference in technique survival (p = 0.196), and peritonitis-free survival (log-rank 0.238), which were confirmed in a fully adjusted Cox regression. Diuresis at baseline and at the end of the first year was similar between groups (p = 0.799 and p = 0.354, respectively). Six out of 18 patients from the PD-KTx group had the immunosuppression maintained and none of those had peritonitis. The reduction of diuresis across the first year of PD was significant for all patients, except for those on continued immunosuppressive therapy.
Conclusion
PD is a worthy dialysis alternative after a failed kidney transplant, providing similar outcomes when compared to patients who started PD for other reasons.
