ResumoObjective:To evaluate the relation among the transition zone of prostate measured by transrectal ultrasound with international prostate symptom score(IPSS), peak urine flow rate(Qmax) and postvoid residual urine volume(PVR), and the volume of transition zone index in evaluating clinical benign prostatic hyperplasia(BPH). Methods: IPSS, Qraax, PVR, transrectal ultrasound volume of the total prostate and the transition zone were prospectively evaluated in 286 cases with symptomatic BPH, and the transition zone index was calculated. Results:There was no significant correlation among total prostate volume and IPSS( r = 0. 092, P 0. 05), Qmax (r= -0. 125, P 0. 05), PVR(r = 0.078, P 0.05), but a stonger correlation among TZV and IPSS (r = 0. 385, P 0.01), Qmax( r= -0.412, P 0. 001), PVR( r = 0. 426, P 0. 001), and a signicant correlation among TZI and IPSS( r = 0. 436, P 0.001), Qmax (r= -0.534, P 0.001), PVR(r = 0.528, P 0.001) . There was a significant difference ( P 0. 01)in IPSS, Qmax and PVR between patients with TZI 0. 50 and those with TZI 0. 50. Conclusion: Transition zone index is a parameter that correlates significantly with the symptom of BPH and available in evaluating the severity of obstrution.
