ABSTRACT
Objective To evaluate the efficacy of combination therapy with finasteride and doxazosin in benign prostatic hyperplasia/ lower urinary tract symptoms (BPH/LUTS) patients with intravesical prostatic profusion (IPP).Methods A total of 322 BPH/LUTS patients who accepted combination therapy with finasteride and doxazosin were enrolled in this study.Patients were divided into 4 groups according to the degree of IPPgroup Ⅰ(IPP>10 mm),group 2 (IPP between 5 mm and 10 mm),group 3 (IPP<5 mm),control group (without IPP).All patients were received inasteride 5 mg once per day and doxazosin 4 mg once per day for 6 months.International prostate symptom score (IPSS),prostatic specific antigen(PSA),ultrasonographic and urcdynamic evaluation were compared before and after treatment.The correlations between the above factors and IPP were estimated by Logistic regression analysis.Results After 6 month of treament,the changes of IPP degree and the maximal urinary flow rate (Qmax) had no significant differences in group 1,group 2 and group 3 as compared with before treatment (all P>0.05).The IPSS in group 1 was not significantly different before and after treatment (P>0.05).There were significant differences in the PSA level,IPSS,total prostate volume (TPV),transition zone volume (TZV),residual urine volume (PVR) in the 4 groups before and after treatment (all P<0.05).Logistic regression analysis showed that PVR and Qmax had positive and negative correlations with IPP (P<0.001 and P=0.024),respectively.Conclusions Combination therapy with finasteride and doxazosin can significantly improve the symptoms of LUST and reduce the total prostate volume in patients with BPH/LUTS,but for BPH patients with IPP,the combination therapy can not effectively alleviate the degree of IPP.The increase of residual urine volume and decrease of Qmax may enhance the risk of bladder outlet obstruction in BPH patients with IPP.
