Tissue is harvested via the patient's perineum. A grid (template) allows for a precise biopsy according to a given scheme. Previously identified suspicious areas can also be punctured precisely. This procedure is performed under a short anaesthetic. The number of samples (14 to 24 punches) varies with the size of the prostate.
Reduced risk of infection
The risk of infection is reduced in perineal biopsy because the tissue is not removed through the perineum and germ transfer from the intestine cannot take place. However, the risk of secondary bleeding is somewhat higher than with biopsy through the intestine.
Suitable for whom?
The perineal prostate biopsy is particularly suitable for patients with an increased risk of infection and suspected tumors in a region that is less accessible for the standard biopsy.
