Serum acid phosphatase in TUR syndrome.

The value of serum acid phosphatase (S-ACP) as a marker of transurethral resection (TUR) syndrome was studied in 105 patients undergoing TURP. In ten patients who developed TUR syndrome the elevation of S-ACP was statistically significantly higher than in the rest of the patients. In seven patients prostatic cancer was diagnosed in the resection chips, but there were no differences in the S-ACP levels during TURP between these patients and the rest of the group. According to the present study, S-ACP seems to be a reliable and cheap marker of TUR syndrome, but the method is slow as compared to ethanol, which restricts its use.
