Summary

Prostate tissue biopsy is performed with either transrectal or transperineal approach. These two methods are usually based on tissue sampling with an ultrasound-guided core needle biopsy. Transperineal prostate biopsy can be done either with a conventional noncoaxial technique or with a coaxial technique. In conventional transperineal technique, biopsy needle is inserted repeatedly for each tissue sampling. Alternatively, a coaxial needle can be placed over the perineum; then, the direction of the biopsy can be changed by tilting the coaxial needle. In this prospective study, the investigators sought to compare the procedural time and the complication rate of coaxial technique with those of noncoaxial technique in transperineal prostate biopsy.

Conditions

Interventions

DEVICE

coaxial prostate biopsy

In this method, a larger introducing needle is needed for the puncture. The introducing needle is placed over the perineum. The biopsy needle is inserted throughout the introducing needle.Then, the direction of the biopsy is changed by tilting the coaxial needle. The investigator needs to puncture the prostate capsule only once for sampling at each each side of the prostate (right and left sides).

DEVICE

noncoaxial prostate biopsy

In this method, there is no introducing needle. Biopsy needle is inserted repeatedly for each tissue sampling (at least fourteen times). A smaller biopsy needle is used for the puncture in this method. The main disadvantage of the coaxial technique is that a larger introducing needle is needed for the puncture (12). On the other whand, the advantage of noncoaxial method is that the needle is within the prostate for only a few seconds to document needle position with ultrasonography before firing
