Long-Term Outcomes and Survival of Peritoneal Dialysis Beyond 10 Years: A Single-Center Study

Introduction: Long-term peritoneal dialysis (PD) beyond 10 years is uncommon and reflects both advances in dialysis care and the complexity of long-term patient management. The objective of this study is to describe the clinical characteristics, complications, and outcomes of patients undergoing peritoneal dialysis for more than 10 years, and to identify factors associated with long-term technique survival. Methods: This is a retrospective, descriptive, and analytical study including 12 patients treated with peritoneal dialysis (PD) for more than 10 years between June 2006 and January 2024. Data collected included demographics, comorbidities, dialysis parameters, complications, and outcomes. Results: The mean age at PD initiation was 45.5 ± 16.5 years. Tubulointerstitial nephropathy was the most common etiology of end-stage kidney disease. The mean duration on PD was 10.4 ± 0.9 years. During follow-up, residual kidney function significantly declined. Seven patients remained on PD at last follow-up. The peritonitis rate was low (0.024 episodes/patient-month), with favorable technique survival and no cases of encapsulating peritoneal sclerosis. Discussion: PD beyond 10 years is feasible with proper patient selection, education, and follow-up. Preservation of residual kidney function and effective management of complications are key to long-term success, especially in non-transplantable patients.
