Clinical significance of the parameters of prostate volume measured by TRUS in evaluating bladder outlet obstruction / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVES</b>To explore the parameters of prostate volume measured by TRUS in diagnosing bladder outlet obstruction (BOO) from BPH.</p><p><b>METHODS</b>Prostate volume(PV), transition zone volume(TZV) and transition zone index (TZI) were measured with TRUS in 116 cases of BPH aged from 59-75. Urodynamics were conducted, including Qmax, Pdet. Qmax and AG value. The correlation analysis was performed among them.</p><p><b>RESULTS</b>PV, TZV and TZI were (69.7 +/- 45.9) ml, (43.5 +/- 25.6) ml and 0.57 +/- 0.14, respectively. Qmax, Pdet. Qmax and AG were (8.31 +/- 5.12) ml/s, (82.34 +/- 33.47) cm H2O and 66.72 +/- 30.46, respectively. IPSS and PSA were 25.3 +/- 4.7 and (4.12 +/- 3.64) ng/ml, respectively. The correlation analysis showed TZI (r = 0.742, P = 0.017) and TZV (r = 0.674, P = 0.031) were positively correlated with AG value. IPSS was positively correlated with TZV and TZI. There was also a positive correlation between PSA and PV, TZV and TZI.</p><p><b>CONCLUSIONS</b>As urodynamics, the parameters of prostate volume measured by TRUS are reliable to diagnose BOO due to BPH.</p>
