Ultrasound image features of intravesical prostatic protrusion indicated failure of medication therapy of finasteride and doxazosin in patients with benign prostatic hyperplasia (LUTS/BPH).

Abstract:

BACKGROUND:Intravesical prostatic protrusion (IPP) is a type of benign prostatic hyperplasia (BPH) adenoma, and it plays a critical role in the pathogenesis of bladder outlet obstruction in patients with lower urinary tract syndromes (LUTS/BPH). AIMS:The goal of this study was to investigate the effect of a combination therapy with finasteride and doxazosin on IPP in BPU/LUTS patients. METHODS:A total of 322 BPH patients with enlarged prostatic volume as well as moderate to severe symptom scores were enrolled and divided into four groups according to the degree of IPP (IPP > 10 mm, 5-10 mm, <5 mm and no IPP) in this study. Aggravated International Prostatic Symptom Score (IPSS), acute urinary retention or relevant urinary complications were considered as failure of the therapy. The degrees of IPP were recorded before and after 6 months of treatment. Student's t test and χ 2 were performed between the baseline and endpoint of the therapy. RESULTS:The results showed that the total prostate volume (TPV) and transition zone volume (TZV) of the prostate decreased significantly after 6-month combination therapy (P < 0.05), while no significant changes in IPP were observed at that point (P > 0.05). Failure rates of the medication differed significantly among the four groups. CONCLUSIONS:The study indicated that the combination therapy using finasteride and doxazosin could not reduce the degree of IPP. LUTS/BPH patients with IPP which contributes to the failure of medication tend to have a higher risk of progression.
