The event occurred nearly 24 hours after the procedure. The patient was treated with intravenous pentoxifyllin and hyperbaric oxygenation. Total reverse of the ischemia was observed. The complications associated with circumcision and DPNB were reviewed and discussed.展开更多

Methods: The fPSA/tPSA ratio in the serum was analyzed in 187 men with tPSA ranging between 4.0 and 20.0 μg/L. All of them underwent ultrasound guided sextant prostatic biopsy. The results were calculated by SPSS 10.0 software. Results: (1) When the tPSA was within the ranges of 4.0 - 10.0 and 10.0 -20.0 μg/L, the prostate cancer detection rate was 18.1 % and 22.5 %, respectively; (2) The area under the curve (AUC) was bigger in fPSA/tPSA than in tPSA (P<0.05) in all the men; (3) When the cut off value of fPSA/tPSA ratio was set at 0.25 and the tPSA at 4.0 - 10.0 μg/L and 10.0 - 20.0 μg/L, the diagnostic sensitivity of tPSA was 90.5 % and 87.5 %, respectively. Thus at the tPSA ranges of 4.0 - 10.0 and 10.0 - 20.0 μg/L, 26.7 % and 11.3 % of biopsies could be avoided, respectively. Conclusion: The use of fPSA/tPSA ratio can improve the prostate cancer detection rate and reduce unnecessary biopsies when tPSA is within the range of 4.0 - 20.0 μg/L.展开更多
