Bleeding complications associated with percutaneous renal biopsy using Biopince^® needle

Excerpt

Renal biopsy is a valuable tool in the diagnosis of renal diseases; however, bleeding remains a serious complication of the procedure [1‐4]. We have used 18-G BioPince^® (Full Core Biopsy Instrument; Medical Device Technologies Inc. Gainesville, FL) needle for performing renal biopsies in the recent years. BioPince technology is built around a tri-axial “Cut and Trap” cannula system, which is designed to cut the specimen and hold it in the cannula. This mechanism supposedly delivers cylindrical, full-length specimens that are complete and largely undamaged, thereby greatly improving the diagnostic value of the sample. This instrument is also claimed to result in less trauma to the patient, and less crush artifact and tissue fragmentation. …
