Urodynamic evaluation, International Prostate Symptom Score (IPSS), uroflowmetry, post-void residual volume (PVR) check and transrectal ultrasound were performed. 20〈B001〈40 was defined as equivocal BOO and BOO1 〉~40 as definite BOO. Changes of IPSS, Qmax, PVR and correlation analysis was performed between the degree of improvement of Qmax, subdomains of I PSS and BOO1. Fifty-four patients showed equivocal BOO and 80 patients showed definite BOO. Preoperatively equivocal BOO group and definite BOO group showed significant differences in maximal bladder capacity and prevalence of detrusor overactivity, whereas no difference was noted in prostate volume. Postoperatively both groups showed improvements in Qmax, obstructive (IPSSO) and irritative (IPSSI) subdomain of IPSS, but the degree of improvement in Qmax and IPSSI subdomain was statistically significantly greater in definite BOO group. The degree of improvement of Qmax and IPSSI showed weak correlation with preoperative BOO1. As a weak correlation was identified between preoperative degree of BOO and outcome of TURP, other factors other than BOO1 such as severity of patients' symptoms should be considered in deciding treatment modality.展开更多
