Since the introduction of dialyzer reuse more than three decades ago, several studies have reported its safety, efficacy and cost effectiveness. Reuse of hemodialyzer was prospectively studied in ten chronic hemodialysis (HD) patients recruited from the renal unit, the King Khalid University Hospital, Riyadh, Saudi Arabia, for three months. During the study period, 66 dialyzers were used for 408 sessions of HD, with a mean reuse of 6.2 5.3 episodes per dialyser, the mean of maximum reuse episodes being 13.7 8.0. The urea reduction ratio was maintained between 73 5% at baseline to 71.2 9.03% (p=0.53) at the maximum reuse. Similarly phosphate reduction with each HD session was maintained; mean decrease in phosphate levels was 0.67 mmol/L. Significant increase in heparin requirement was noted; however, the risk of bleeding was not increased. Hematocrit levels increased from 30.4 4.1% to 33.2 3.6% at the end of the study (p=0.6). Albumin leak in dialysate decreased with each reuse; baseline 8.27 7.93 mg/L to 2.8 0.4 mg/L at maximum reuse (p=0.04). Serum albumin levels remained stable. No short-term adverse effects on patients' morbidity and mortality were noted. Total cost savings of 53% was achieved with the reuse of dialyzers, excluding capital equipment used for preparation for reuse. In conclusion, dialyzer reuse seems to be safe and may provide an economical and efficient dialysis. Studies involving larger number of patients is required to validate this observation.
