Prostate-specific antigen in urine.

摘要: We investigated concentrations of prostate-specific antigen (PSA) in mid-stream urine 213 patients. Among them were 34 females. Diagnoses the male patients 42 benign prostatic hypertrophy (BPH), 21 localized prostate cancer prior to radical prostatectomy (RP), 15 post-RP without distant or local recurrence, 5 with recurrence and 82 other urological diseases. PSA levels determined by Hybritech Tandem E method. Female samples positive 38% cases. This finding men after RP is most likely due extraprostatic production periurethral glands. Urinary do not differ between BPH, organ-confined diagnoses. In some cases, however, can be elevated tumor when serum are still undetectably low. indicates that determination urinary concentration might useful follow-up RP.
