Abstract:
OBJECTIVESTo explore the parameters of prostate volume measured by TRUS in diagnosing bladder outlet obstruction (BOO) from BPH.
METHODSProstate 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.
RESULTSPV, 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.
CONCLUSIONSAs urodynamics, the parameters of prostate volume measured by TRUS are reliable to diagnose BOO due to BPH.
