peritoneal dialysis in morocco: nineteen years of experience from the first national center and evaluation of technique survival and mortality

Background and aims: peritoneal dialysis (pd) remains underused despite being a valid alternative to hemodialysis. this study assessed patients' clinical profiles, technique survival, and mortality at morocco's first pd center. methods: this retrospective study evaluated 247 patients treated with pd from june 2006 to may 2025, with no exclusions. required data were obtained from the french-language pd registry and medical records. finally, t-tests, anova, chi-square tests, and stepwise backward logistic regression were used for statistical analysis (p<0.05). results: overall, 233 (94.3%) patients chose pd as their renal replacement therapy (rrt). the average age was 47.5±17.3 years. in addition, 62.7% were male, and 25.4% had diabetes. the median follow-up period was 4.0 years, with an interquartile range of 2.0–7.0. technique survival rates at 1, 3, and 5 years were 90%, 55%, and 45%, respectively. in addition, patient survival rates were 88%, 65%, and 50%. the incidence of peritonitis was 0.48 episodes per patient-year and was the primary cause of technique failure (53.6%) and contributed to 11.9% of deaths. logistic regression demonstrated a technique failure associated with diabetes (p=0.038). mortality was linked to age>60 (p=0.022), vascular access failure (p=0.013), and assisted pd (p=0.003). hypoalbuminemia (p=0.281), anemia (p=0.176), and hypophosphatemia (p=0.223) were not significant. conclusion: pd is a long-term rrt in morocco. mortality is linked to advanced age, vascular access failure, and assisted pd. continued patient education and staff training are vital.
