Serum PSA and transition zone index as predictors of acute urinary retention in benign prostate hyperplasia / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>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).</p><p><b>METHODS</b>The complete data of 602 cases of BPH were reviewed and analyzed.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>Serum PSA and TZI were powerful predictors of the risk of AUR in men with BPH.</p>
