Laparoscopic renal exploration and biopsy.

A new and novel technique to obtain renal biopsy specimens using laparoscopy is presented. In some patients there are contraindications to obtaining biopsy material through standard percutaneous techniques. Open renal biopsy has been the procedure of choice in these patients. The laparoscopic approach can accomplish the same surgical objectives as open renal biopsy without the associated morbidity. This report discusses the indications, contraindications, materials, methods, and techniques associated with this new procedure.
