Use of Biopsy Sheath to Improve Standardization of Renal Mass Biopsy in Tissue-Ablative Procedures

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.
