Accuracy and implications of percutaneous renal biopsy in the management of renal masses.

Introduction: Percutaneous renal biopsy in patients with renal masses is increasing. We investigated the accuracy of percutaneous renal mass biopsy results in patients undergoing evaluation of solid renal masses.

Methods: A retrospective review was performed of patients in the Kaiser Permanente Southern California Region who underwent computed tomography or ultrasound-guided percutaneous renal biopsy of a solid renal mass between January 2005 and December 2009.

Differences in left and right laparoscopic adrenalectomy.

Background And Objectives: The classic belief is that right-sided laparoscopic adrenalectomy is technically more difficult to perform than left-sided. The purpose of this study was to determine whether objective outcomes are different for the right- versus left- sided operation.

Methods: A retrospective review of 163 laparoscopic adrenalectomies was performed to compare outcomes.
