[Serum gamma-seminoprotein on patients suffering from urinary retention due to BPH]

Serum gamma-Seminoprotein (gamma-Sm) of 33 patients suffering from urinary retention due to BPH was evaluated. In acute urinary retention gamma-Sm was 17.1 +/- 54.9 ng/ml (N = 33) and its positive rate was 72.7%. After indwelling urethral catherization for one week gamma-Sm fell to 3.7 +/- 3.6 ng/ml (N = 17) and its positive rate was 42.8%. gamma-Sm measured after one month was negative on all cases. It was showed that gamma-Sm in acute urinary retention increased and after releasing from urinary retention it was rapidly normalized. It is necessary to take into account the above mentioned findings on evaluation of gamma-Sm as a tumormarker of prostatic carcinoma.
