Abstract
Introduction: Despite increasing resistance of enterobacteria against fluoroquinolones (FLU), they are still widely used during transrectal prostate biopsy (TRPB). This study was designed to analyse infectious complications and risk factors between FLU, cephalosporines (CEPH) and selective other antibiotics (O-AB) used during TRPB. Methods: 664 patients were included retrospectively (152 FLU, 452 CEPH and 60 O-AB). Infectious complications were defined as fever >38.0°C, the in-house definition of complicated urinary tract infection (cUTI) (if all applied: fever >38.0°C, leucocytosis >11.000/µL and positive urine dipstick) or postinterventional bacteriuria. Hospitalisation rate, duration and comorbidities were also assessed. χ2 and Fisher’s exact test were used for group comparison. Multivariate regression analysis assessed the association of comorbidities with infectious complications. Results: FLU and CEPH were indifferent regarding infectious complications, however in the O-AB group significantly more common compared to FLU and CEPH (11.6, 13.3, 25%, p < 0.05). Duration of hospital stay in CEPH was significantly shorter compared to FLU and O-AB (4.1 vs. 6.3 vs. 8.2 days, p < 0.05). Arterial hypertension showed increased association with fever (OR 6.002 (1.178; 30.597) p = 0.031) and cUTI (OR 6.006 (1.207; 29.891) p = 0.029). Conclusion: Infectious complications were low and indifferent between FLU and CEPH but significantly more frequent in O-AB. Arterial hypertension was significantly associated with postinterventional fever and cUTI.
