Zusammenfassung:To determine whether the peri-procedural administration of low-dose aspirin increases the risk of bleeding complications for patients undergoing extended prostate biopsies. From February 2007 to September 2008, 530 men undergoing extended needle biopsies were divided in two groups; those receiving aspirin and those not receiving aspirin. The morbidity of the procedure, with emphasis on hemorrhagic complications, was assessed prospectively using two standardized questionnaires. There were no significant differences between the two groups regarding the mean number of biopsy cores (12.9 +/- 1.6 vs. 13.1 +/- 1.2 cores, p = 0.09). No major biopsy-related complications were noted. Statistical analysis did not demonstrate significant differences in the rate of hematuria (64.5% vs. 60.6%, p = 0.46), rectal bleeding (33.6% vs. 25.9%, p = 0.09) or hemospermia (90.1% vs. 86.9%, p = 0.45). The mean duration of hematuria and rectal bleeding was significantly greater in the aspirin group compared to the control group (4.45 +/- 2.7 vs. 2.4 +/- 2.6, p = < 0.001 and 3.3 +/- 1.3 vs. 1.9 +/- 0.7, p < 0.001). Multivariate logistic regression analysis revealed that only younger patients (mean age 60.1 +/- 5.8 years) with a lower body mass index (< 25 kg/m2) receiving aspirin were at a higher risk (odds ratio = 3.46, p = 0.047) for developing hematuria and rectal bleeding after the procedure. The continuing use of low-dose aspirin in patients undergoing extended prostatic biopsy is a relatively safe option since it does not increase the morbidity of the procedure.
