[Effects of transurethral resection on the serum concentration of prostate specific antigen and prostatic acid...

Serum concentration of PSA and PAP in 30 patients (25 prostate benign hyperplasias and 5 carcinomas) are evaluated prior to transurethral resection, right at the end, after 24 hours and 5 days later. Following TUR a significant increase in BHP is detected, this being less severe in the case of carcinomas. Subsequently, after 24 hours, PSA and PAP levels in BHPs are similar to baseline values, while there is a significant decrease in carcinomas after 5 days. Thus, determination of these markers in prostatic carcinomas should never be postponed after a TUR.
