Purpose:
We used a biopsy sheath to standardize and improve biopsy specimens obtained during laparoscopic cryoablation.
Materials And Method:
Tru-Cut biopsy was performed using a resized sheath in three patients undergoing laparoscopic cryoablation of renal masses.
Results:
All three biopsy specimens were sufficient for pathologic evaluation and representative of the tissue mass.
Conclusions:
The application of a biopsy sheath to standardize the depth of needle penetration during Tru-Cut biopsy provides better results and minimizes false-negative studies.
