Relationship between metabolic syndrome and postprostatectomy recurrence of benign prostatic hyperplasia in the elderly / 中华老年医学杂志

ABSTRACT

Objective To investigate the relationship between metabolic syndrome (MS) and early recurrence of benign prostatic hyperplasia (BPH) after prostatectomy in the elderly.Methods A total of 152 men aged 65 to 88 years with prostatectomy for more than 5 years were enrolled from August 2008 to March 2013.Blood pressure,body weight,body height,body mass index (BMI) and international prostate symptom score (IPSS) were detected.Levels of fasting blood glucose (FBG),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),prostate specific antigen (PSA) and maximum urinary flow rate (Qmax) were determined.The correlation of MS-related parameters with prostate volume,IPSS and Qmax were evaluated.Results BPH recurrence rate was significantly higher in patients with MS than without MS (11/26 vs.27/126,x2=12.76,P＜0.001).PSA level,prostate volume and IPSS were significantly higher or larger in the MS group than in the non-MS group [(1.96±0.82)μg/L vs.(1.81±0.90)μg/L,(28.26±5.50) ml vs.(22.38±4.00)ml,(11.12±3.18)vs.(7.11±2.37),F=28.654,44.41,38.56,respectively,P＜0.001],while Qmax value was significantly lower in the MS group than in the non-MS group [(14.77±5.29) ml/s vs.(19.80±4.70) ml/s,F=59.48,P＜0.001].The liner regression analysis showed that in postprostatectomy recurrence group,PV and IPSS had significantly positive correlations with levels of FBG and TG,and BMI (P＜0.05),and had significantly positive correlations with BMI and FBG in non-recurrence group (P＜0.05),while Qmax had a significantly negative correlation with BMI,systolic blood pressure and FBG in the two groups (P＜0.05).Conclusions There is a significant relationship between MS and higher BPH recurrence in elderly patients.
