The Influence of Prostate Inflammation on Overactive Bladder in Patients with Benign Prostatic Hyperplasia

Objective To investigate the influence of prostate inflammation on overactive bladder in patients with benign prostatic hyperplasia.Methods Prostate inflammation was assessed as none,mild,moderate,or severe.According to the degree of prostatic inflammation,260 patients with a pathologic diagnosis of BPH were divided into four groups.The differences between urodynamic results and the prevalence of OAB of four groups were retrospectively analyzed.Results The degree of prostate inflammation rose with increasing International Prostate Symptom Score(IPSS) and prostate size,with decreasing first desire bladder volume and urgent desire bladder volume(P0.05).The prevalence of OAB rose continuously with increasing degree of prostatic inflammation,ranging from 42.30% in none inflammation group to 70.37% in severe inflammation group(P =0.003).Statistically no significant correlation was found between the degree of prostatic inflammation and the prevalence of detrusor overactivity(P =0.066).Conclusion The degree of prostatitis inflammation was found to be positively correlated with the prevalence of overactive bladder in patients with benign prostatic hyperplasia.The prevalence of OAB rose continuously with increasing degree of prostate inflammation.
