Purpose: The diagnostic yield of prostate biopsy is limited. Increasing the number of cores enhances the cancer detection rate by sampling additional sites and obtaining more tissue. An alternative way to inspect more tissue would be to obtain longer cores. However, the impact of biopsy core length on cancer detection rate is an undervalued topic. We assessed the role of biopsy core length in prostate biopsy and determined the minimal tissue length to serve as quality assurance.
