Objectives: The objective of this study was to assess the value of a urine bacterial culture performed before prostate biopsy. Methods: We performed a prospective study on 353 patients who underwent prostate biopsy. All patients had a urine bacterial culture performed before biopsy. We compared the outcomes of patients with bacteriuria (left untreated) to those of patients without bacteriuria. Results: Of the 353 men, 12 had a pre-biopsy positive bacterial culture and underwent prostate biopsy without any infectious complication. Fifteen patients with a negative pre-biopsy culture developed a post-biopsy positive bacterial culture, but remained asymptomatic without any treatment. Only 4 men from the group without pre-biopsy bacteriuria developed an infectious complication, requiring 3 weeks of antibiotic therapy. The complication rates were similar for both groups. Conclusion: Our results suggest that routine urine bacterial culture before prostate biopsy is not useful when antibiotic prophylaxis and enema are is performed. We do however suggest performing a urine bacterial culture before prostate biopsy for patients with a previous history of urinary tract infections.
