High diagnostic accuracy of inguinal ultrasonography and fine needle aspiration followed by dynamic sentinel lymph node biopsy in men with non-palpable and palpable inguinal lymph nodes.

To assess the accuracy of dynamic sentinel lymph node biopsy (DSNB) after negative ultrasonography (US) guided fine needle aspiration (FNA) for ILN staging.

We performed a retrospective analysis of men with ≥T1G2 penile cancer and negative inguinal US guided FNA undergoing DSNB.
