Changes in Renal Perfusion During Hemodialysis in Patients with End-stage Renal Disease

Residual renal function (RRF) characteristically declines after patients with end-stage renal disease (ESRD) initiate dialysis. Although RRF preservation correlates with improved patient\'s quality of life and survival prospects, poor understanding of the pathophysiology underlying RRF decline limits protection strategies.

Hemodialysis (HD) is the primary renal replacement therapy for patients with end-stage renal disease. However, residual renal function (RRF) characteristically declines after these individuals start dialysis. This loss of RRF not only impacts the adequacy of dialysis and control of complications but also affects the patient\'s quality of life and survival prospects. Due to a lack of clear understanding regarding the pathophysiology underlying this decline in RRF, no effective strategies exist for its preservation at present. The objective of this study is to explore the changes in renal perfusion during hemodialysis in patients with end-stage renal disease, and provide a new idea for protection of RRF. This study was an observational study, and no interventions were performed.
