[Serum PSA and transition zone index as predictors of acute urinary retention in benign prostate hyperplasia].
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).


CONCLUSIONS
Serum PSA and TZI were powerful predictors of the risk of AUR in men with BPH.
