Abstract:
Objective:To explore the correlation between serum cystatin C (Cys C)content and renal function in aged patients with benign prostatic hyperplasia (BPH).Methods:Clinical data of 237 aged BPH patients were retro-spectively analyzed.According to international prostate symptom score (IPSS),they were divided into mild group (n=25),moderate group (n=67)and severe group (n= 145);another 110 patients without prostatic hyperplasia were enrolled as normal control group in the same period.Levels of serum Cys C,blood urea nitrogen (BUN),ser-um creatinine (Scr),fasting blood glucose (FBG),blood lipids and prostate-specific antigen (PSA)were measured in all groups,and prostate volume (PV)was calculated.Results:Compared with normal control group,PV signifi-cantly rose [(18.94±4.62)ml vs.(40.09±12.72)ml],maximum urinary flow rate (Qmax)significantly reduced [(18.67±4.60)ml/s vs.(9.93±3.54)ml/s],and serum Cys C level significantly increased [(1.03±0.23)mg/L vs.(1.53±0.61)mg/L]in BPH group,P <0.01 all.Subgroup analysis indicated that serum Cys C levels in mild, moderate and severe group [(1.32±0.45)mg/L,(1.42±0.32)mg/L,(1.61 ±0.64)mg/L]were significantly higher than that of normal control group,P <0.01 all;and that of severe group was significantly higher than those of mild group and moderate group (P <0.01 or P <0.05).Pearson correlation analysis indicated that serum Cys C level was positively correlated with of age,SBP,DBP,FBG,BUN,Scr,PV and IPSS (r=0.179~0.580,P <0.05 or P <0.01),and inversely correlated with Qmax (r=-0.243,P <0.05)in BPH patients.Conclusion:Serum Cys C level significantly rise,and related with BPH degree,correlated with renal function in aged BPH patients,which can be used to predict renal function of these patients.
