Objective:
To evaluate prostate specific antigen (PSA) and transition zone index (TZI) as predictors of acute urinary retention (AUR) in men with benign prostate hyperplasia(BPH).
Methods:
The complete data of 602 cases of BPH were reviewed and analyzed.
Results:
Mean serum PSA and TZI were (6.60 +/- 3.4) microgram/L and (0.71 +/- 0.14) in AUR group, (3.51 +/- 2.3) microgram/L and (0.46 +/- 0.21) in non-AUR group, respectively. There were significant differences in serum PSA and TZI between the two groups(P < 0.05). The difference in incidence of AUR between serum PSA < 4.0 micrograms/L, 4.0-10.0 micrograms/L and PSA > 10.0 micrograms/L was significant (P < 0.05). There was significant positive correlation between serum PSA and TZI(r = 0.213, P < 0.01).
Conclusion:
Serum PSA and TZI were powerful predictors of the risk of AUR in men with BPH.
