To describe the efficacy of percutaneous core biopsy of penile corpora
l tissue, on ten impotent men, the biopsy was performed with a 19 and
a 20 gauge core biopsy co-axial system using an automatic biopsy devic
e. All biopsies were performed on an outpatient basis under local anes
thesia. Adequate biopsy specimens were obtained in all. Percutaneous c
ore biopsy of the penis is a safe procedure that is technically easy t
o perform.
