  1. Smilov, E. Aleksandrov, I. Lozev, P. Lozev

The prostate carcinoma is currently one of the most often diagnosed cancers in men. The prostate biopsy has undergone significant development during the last century. From a procedure with considerable morbidity it has become one of the most often performed procedures in outpatient setting. The application of prostate specific antigen screening, TRUS (transrectal ultrasound imaging), the automatic and semi-automatic biopsy devices under ultrasound guidance, has elaborated the biopsy techniques for prostate carcinoma diagnosis. The biopsy procedure consists of: physical preparation of the rectum, antibiotic prophylaxis, digital rectal examination, TRUS, application of local anesthesia, performance of systemic and targeted puncturing of the prostate gland, documenting the procedure and processing of the sampled cores, patients follow up and treatment of eventually occurring complications. Violating any of these steps may jeopardize the efficacy of prostate carcinoma diagnosis, lead to signifi cant complications or trigger a refusal by the patient the biopsy procedure to be executed at all.
