To explore the parameters of prostate volume measured by TRUS in diagnosing bladder outlet obstruction (BOO) from BPH.
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.
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.
As urodynamics, the parameters of prostate volume measured by TRUS are reliable to diagnose BOO due to BPH.
探讨经直肠超声（TRUS）测量前列腺体积的各项参数在诊断良性前列腺增生（BPH）所致膀胱出口梗阻（BOO）中的价值。
采用TRUS测量116例年龄在59 - 75岁的BPH患者的前列腺体积（PV）、移行区体积（TZV）及移行区指数（TZI）。进行尿动力学检查，包括最大尿流率（Qmax）、排尿期膀胱内压（Pdet.Qmax）及梗阻值（AG值）。对上述指标进行相关性分析。
PV、TZV和TZI分别为（69.7±45.9）ml、（43.5±25.6）ml和0.57±0.14。Qmax、Pdet.Qmax和AG分别为（8.31±5.12）ml/s、（82.34±33.47）cmH₂O和66.72±30.46。国际前列腺症状评分（IPSS）和前列腺特异抗原（PSA）分别为25.3±4.7和（4.12±3.64）ng/ml。相关性分析显示，TZI（r = 0.742，P = 0.017）和TZV（r = 0.674，P = 0.031）与AG值呈正相关。IPSS与TZV和TZI呈正相关。PSA与PV、TZV和TZI也呈正相关。
作为尿动力学检查指标，TRUS测量的前列腺体积参数在诊断BPH所致BOO方面具有可靠价值。
