Estimated time to complete the educational activity: 1 hour

This activity is jointly sponsored by Medical Education Resources and Haymarket Medical Education.

Statement of Need: The urologic community to date has been reticent to rely on renal biopsy in the treatment of renal cortical masses. The historically common presentation of renal tumors—a classic triad of pain, a flank mass, and hematuria—almost always resulted in the discovery of a large renal tumor. These tumors were mostly malignant, and, by definition, symptomatic. As such, the use of renal biospy was not warranted. In addition, the presence of small incidental renal cortical neoplasms was quite rare in the past, and biopsy even rarer. This algorithm must be re-evaluated, as incidental small renal cortical neoplasms are more frequently seen today.

Target Audience: This activity has been designed to meet the educational needs of urologists and allied healthcare clinicians who treat patients with nephrotic and acute nephritic syndromes, and associated cancer.

Educational Objectives: After completing the activity, the participant should be better able to: < /p>

  • Review the epidemiology of small renal cortical neoplasm.
  • Discuss renal biopsy techniques, image guidance, and type of biopsy.
  • Underline complications associated with a biopsy of the kidney.
