Retroperitoneal Laparoscopic Radical Nephrectomy for Large (>7 cm) Solid Renal Tumors: Comparison of Perioperative Outcomes with the Transperitoneal Approach

Abstract

Retroperitoneal LRN for a large (>7 cm) solid renal tumor demonstrated a superior result in terms of operation time, estimated blood loss, and time to start diet than transperitoneal LRN. Other perioperative outcomes and complication rate were comparable between the two approaches. We believe that with sufficient experience, retroperitoneal LRN may be an effective and safe procedure for large (>7 cm) solid renal tumors.
