Abstract
OBJECTIVE: This study aims to compare the clinical application value of high-flux dialysis with low-flux dialysis in patients without significantly improved renal function after cervical cancer and obstructive renal failure catheterisation. METHODS: This prospective randomised study was conducted from January 2018 to December 2019. Eighty cervical cancer patients with obstructive renal failure who showed no significant renal function improvement after catheterisation were randomised into two groups (n = 40 in each group) in the Second People's Hospital of Yibin City. High-flux and low-flux dialysis were employed in the experimental group and the control group, respectively. Treatments in both groups were provided every other day, with the whole course lasting one week. Data were recorded before and after dialysis included inflammatory factors such as IL-6, CRP and TNF-a, large and moderate molecular toxins (e.g., β2 micro-globulin, parathyrin (PTH) and cysteine protease inhibitor). Renal function changes during the dialysis were also recorded. Afterwards, the two groups were compared regarding the overall efficacy. RESULTS: Both the experimental group and the control group experienced a significant decrease in IL-6, CRP, TNF-a, β2 micro-globulin, PTH and cysteine protease inhibitor, with the decrease in the experimental group being more evident (p < 0.05). After dialysis was completed, the experimental group restored renal function indicators such as Cre, CysC and serum K+ levels more quickly than the control group (p < 0.05). The effective rate was 100% for the experimental group and 87.5% for the control group. The intragroup difference in the efficacy.was significant. CONCLUSIONS: High-flux dialysis appears to be more beneficial for cervical cancer patients with obstructive renal failure, showing no significant improvement in renal function after catheterisation. It restored renal function more quickly, had more radical draining of inflammatory factors and large and moderate molecular toxins, and had a higher overall effective rate.
