Relationship between benign prostatic hyperplasia and urine albumin excretion / 中华老年医学杂志

ABSTRACT

Objective To investigate the relationship between benign prostatic hyperplasia (BPH) and urine albumin excretion.Methods A total of 258 male inpatients aged 60 to 70 years were enrolled in this study.According to prostate volume (PV) measured by transrectal ultrasonography,patients were divided into BPH group(PV≥20 ml) and NBPH(non benign prostatic hyperplasia) group(PV＜20 ml).Urine albumin and urine creatinine concentrations were measured and urine albumin/creatinine ratio(UACR) was calculated.Fasting blood glucose(FBG) and fasting insulin(FINS) also were measured,insulin resistance index(HOMA-IR) was calculated based on the formula HOMA-IR=ln(FBG × FINS/22.5).The correlation between PV and other indicators were analyzed by Pearson correlation analysis.The risk factors for BPH were analyzed by logistic regression analysis.Results UACR was significantly higher in BPH group than in NBPH group[(163.6± 69.8) mg/g vs.(73.3 ± 55.6) mg/g,t =4.81,P＜ 0.01],and hypertension duration was longer in BPH group than in NBPH group [(9.2±6.6)years vs.(6.0±3.6)years,t=2.27,P＜0.05].The prevalence rate of BPH and PV were increased along with increasing of urine albumin excretion(x2=4.58,F=4.85,respectively,P＜0.05 or 0.01).Prostate volume was positively correlated with UACR,HOMA-IR,hypertension duration,body mass index(r=0.248,0.229,0.183,0.157,respectively,all P ＜ 0.05).Logistic regression analysis indicated that UACR,HOMA-IR and hypertension duration were the risk factors for BPH(OR=16.348,1.040,0.166,respectively,all P ＜0.05).Conclusions BPH is correlated with UACR,which indicates that there is a close relationship between atherosclerosis and BPH.Insulin resistance probably plays an important role in the progression of arteriosclerosis and BPH.
