Objective: To investigate the value of PSA in diagnosing urinary tumors. Methods: The PSA level in serum of 61 cases of urinary tumors was tested with IRMA; and its change was observed after operation. Results: In 28 cases of bladder cancer 23 cases were male, from which 13 cases (56. 6%) were positive while 1 out of 5 female patients is positive (20% ) . In 33 cases of nephrotic cancer 22 cases were male, from which 9 cases were positive (40. 9% ), and 5 out of 11 female ones were positive (45. 4%). There was a significant difference in 61 cases of urinary tumors in comparison with the control group (P<0.01). The PSA level of all the cases dropped to normal ( P > 0.05). Conclusion: PSA is very important for diagnosis of urinary tumors, but it can not be used as a specific index for diagnosis of prostatic diseases.
