[Prostate biopsy: Diagnostic responsibility and recent changes]

In this bibliographic review we reexamine the different features in relation to indication, performance and interpretation of prostatic biopsy (PB). The main objective is to place methodological features involving PB in the current scientific scenario, establishing the correlation between the most relevant and analyzing the historic evolution this procedure has followed, particularly over the last two decades. Prostate biopsy has evolved to be a regular element in urologists` daily practice and its learning process has been simplified to the point it can be approached with adequacy during the first years of residency in Urology. This privileged position PB enjoys in daily practice and the performance obtained from it would have not been a reality without optimization of transrectal ultrasound or local anesthesia techniques, yet reviled in some forums, the real responsible of such success. The consensus reached in the various scientific associations, the clinical guidelines of which are widely consulted worldwide, is the best to support the current state of the art, being the starting point for the addition of new improvements to PB.
