In the study conducted on 29 pre-selected patients, we intended to evaluate the reproducibility of prostatic catheter biopsy (CB) as a minimally invasive procedure, directly comparing it to another well-established method, namely ultrasound-guided fine-needle aspiration biopsy (USG-FNAB). As a direct control we used histopathological evaluation and microbial cultivation of samples obtained by percutaneous Tru-Cut biopsy. Evaluating our data, we found that for establishing proper diagnosis by means of cytology, less invasive catheter biopsy (CB 75.86%) is at least comparable to already proven ultrasound-guided fine needle aspiration biopsy (USG-FNAB 72.41%), while catheter biopsy (CB 13 cases out of 29) was significantly (p < 0.0001) more sensitive in actual identification of infectious agents than ultrasound-guided fine needle aspiration biopsy (USG-FNAB 2 cases of 29).We believe that an early microbial evaluation of patients suffering from prostatic disorders helps to target antimicrobial treatment in the beginning of therapy, reducing the risk of failure due to bacterial resistance.
