Objectives: To explore the parameters of prostate volume measured by TRUS in diagnosing bladder outlet obstruction (BOO) from BPH. Methods: 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. Results: PV, TZV and TZI were ( 69.7 ± 45.9 ) ml, ( 43.5 ± 25.6 ) ml and 0.57 ± 0.14 , respectively....

Objectives: To explore the parameters of prostate volume measured by TRUS in diagnosing bladder outlet obstruction (BOO) from BPH. Methods: 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. Results: 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 ) cmH 2 O 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. Conclusions: As urodynamics, the parameters of prostate volume measured by TRUS are reliable to diagnose BOO due to BPH.

Objective To investigate the sonographic appearance and hemodynamic features of hyperplastic nodules and prostatic cancer nodules in the prostatic transitional zone via color Doppler ultrasonography and to evaluate their clinical significance. Methods A total of 37 cases with prostatic hyperplasia and 14 cases with prostatic cancer were detected to observe their sonographic appearance and to measure the systolic peak volocity(Vs),resistance index(RI) and pulsatility index(PI). Results The sonographic appearance of hyperplastic nodules revealed the shapes more regular and edge more clear than prostatic cancer nodules,The blood flow signals in prostatic cancer nodules were increased and multiple while in hyperplastic nodule the flow was not.There was statistically significant differences in the parameters of flow signals between prostatic cancer nodules and hyperplastic nodules( P <0 05). Conclusions Transrectal color Doppler ultrasonography has important value in distinguishing hyperplastic nodules and prostatic cancer nodules in transitional zone.
