Laparoscopic radical nephrectomy for large renal-cell carcinomas.

Abstract Objectives: We retrospectively reviewed the clinical outcome and long-term cancer control of patients with localized large renal-cell carcinomas (RCCs) who underwent laparoscopic radical nephrectomy in comparison to open procedure. Patients and Methods: One hundred and thirty-one patients with RCCs greater than 7 cm who underwent radical nephrectomy between 1996 and 2008 were studied: 52 patients in the laparoscopy group and 79 in the open group. In this analysis patients who had metastasis or pT4 disease or tumor thrombus in the inferior vena cava were excluded. The median follow-up period was 41 months in the laparoscopy group and 51 months in the open group. Results: Patients in the laparoscopy group had tumors similar in size to those in the open group (88 and 89 mm, respectively), lesser blood loss (245 and 663 mL p < 0.01), but more intraoperative complications (15% and 2.5%). One laparoscopy patient was converted to open surgery because of an injury to the inferior vena cava (IVC). The 5- ...
