Abstract:
Objective:To investigate the effect of improving moderate and severe benign prostatic hyperplasia(BPH)with lower urinary tract symptoms(LUTS)on renal function in elderly patients aged 80 years and over.Methods:A total of 129 inpatients with moderate and severe BPH and its associated LUTS(BPH/LUTS)who took tamsulosin combined with finasteride aged 80 years old and over in Geriatric Department of the First Affiliated Hospital of Zhengzhou University were enrolled in the retrospective study from July 2018 to July 2020.Patients were divided into normal blood pressure group(n=51)and hypertension group(n=78)and divided into normal renal function group(n=77)and CKD3a stage group(n=52).Serum creatinine, estimated glomerular filtration rate(eGFR), prostate volume(PV)and post-void residual urine volume(PVR), and International Prostate Symptom Score(IPSS)were compared before versus after 1, 3 and 6 months of treatment.Multivariable linear regression analysis was performed to evaluate the influence of the most relevant factors on renal function in patients with BPH/LUTS.Results:After 1, 3 and 6 months of tamsulosin combined with finastide treatment, the lower urinary tract symptoms of elderly patients with BPH/LUTS were improved, IPSS score and PVR were decreased, and the differences were statistically significant(all P<0.01).PV, serum creatinine and eGFR were not changed after 6 months of treatment(all P>0.05).However, further subgroup analysis showed that serum creatinine level in hypertension group and CKD3a stage group was increased compared with that before treatment, while eGFR in CKD3a stage group was decreased before treatment, and the difference was statistically significant(all P<0.05).Compared with before treatment, serum creatinine and eGFR in hypertensive group improved after 3 months of treatment, and CKD3a group improved after 1 month of treatment, and the differences were statistically significant(all P<0.05).There were no significant changes in serum creatinine and eGFR in normal blood pressure group and normal renal function group after 6 months of treatment(all P>0.05).Multiple linear regression analysis showed that hypertension( β=2.06, P<0.05)and CKD3a stage( β=17.16, P<0.01)were independent risk factors for creatinine changes before and after treatment.Hypertension( β=-2.27, P<0.01), CKD3a stage( β=-11.93, P<0.01)and CKD3A stage( β=-2.27, P<0.01)were independent risk factors for creatinine changes before and after treatment. P<0.01)and PV before treatment( β=-0.11, P<0.05)were independent risk factors for the change of eGFR before and after treatment. Conclusions:Treatment for moderate and severe BPH/LUTS can improve renal function in elderly patients with hypertension or CKD3a.
