Diversity of Bacterial Urine and Prostate Gland Tissue Cultures in Patients Undergoing Transurethral Prostate Gland Resection.

ABSTRACT

INTRODUCTION: The objective of this study was to identify the types of bacterial colonization of the prostate gland tissue and urine pre- and postoperatively in patients undergoing a transurethral resection (TUR) of the prostate gland. In addition, clinical symptoms and histopathological findings were included. MATERIAL AND METHODS: Forty three patients were investigated. Urine test strips and urine cultures were taken pre- and postoperatively and intraoperatively prostate resection chips were taken for culture. RESULTS: A positive bacterial culture was found in 20 of 43 (46.5%) patients. Preoperatively, a positive bacterial culture was found in 12 patients and postoperatively in 7 patients. Thirteen patients showed a positive culture of the prostate gland tissue. No patient showed the same bacterial isolates in all 3 samples. Postinterventionally, 6 patients of the group with positive bacterial cultures developed complications. From the group of patients without bacterial growth, only one patient developed a postoperative complication. CONCLUSION: The bacterial colonization in the 3 different cultures showed an inhomogeneous spectrum of bacteria without a reproducible pattern. Nevertheless, it clearly demonstrates that the group with a positive culture is at great risk to develop postoperative complications.
