Abstract
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.
