PD patients spent more quality time and were more satisfied than HD patients.1 In the last years, advances in dialysis procedures and new guidelines to treat the chronic renal failure patients have improved their treatment and prolonged their lives. At the same time, the concept of health-related quality of life (HRQoL) strengthened as a new goal to be achieved. The current dialysis guidelines enforce treatments to achieve similar outcomes in the long run, independently of the choice of dialysis treatment.2 Manns et al. in their study concluded that there was no significant difference in HRQoL for prevalent end-stage renal disease patients treated with HD or PD.3 In another study, Wu et al. concluded that that PD did not seem to produce a better QoL than HD for patients who imitated renal replacement therapy. 4 Ginieri-Coccossis. et al. in their study concluded that the results provided evidence that patients in HD treatment modality, particularly those with many years of treatment, experienced a more compromised QoL in comparison to PD patients.5 The results may change due to sociodemographic characteristics of patients. We think that the comparison of the two groups could be more meaningful if the QoL is measured before and after patients are undergone dialysis. Another point of discussion could be that the variations in study results may vary upon longer follow-up durations of these patients. ==== Refs REFERENCES 1 Al Wakeel Jamal Al Harbi Ali Bayoumi Magda Al-Suwaida Karaem Al Ghonaim Mohammed Mishkirye Adel Quality of life in hemodialysis and peritoneal dialysis patients in Saudi Arabia Ann Saudi Med 2012 32 6 570 574 23396018 2 Arenas Valquiria Greco Barros Luciene Fatima Neves Monteiro Lemos Francine Barros Quality of Life: Comparison between patients on automated peritoneal dialysis and patients on hemodialysis Acta Paul Enferm 2009 22 (Especial-Nefrologia) 535 9 3 Manns B Johnson JA Taub K Mortis G Ghali WA Donaldson C Quality of life in patients treated with hemodialysis or peritoneal dialysis: what are the important determinants?
