PATIENTS AND METHODS: Partial nephrectomy performed in our center by June 1996 to December 2008 were reviewed retrospectively. Demographic and tumors characteristics, postoperative complications and patient outcomes were identified. Factors associated with complications and survival were investigated by regression tests.
RESULTS: Of the 96 patients enrolled (mean age 61.4 years±12.8), 13 had renal insufficiency (serum creatinine 120 to 212μmol/L). The mean tumor size was 32mm (±13.9) and 57 (79.2%) corresponded to clear cell carcinoma. The overall rate of postoperative complications was 26%, including 8.3% of hemorrhagic complications and 3.1% of urinary complications. None of the analyzed variables were associated with the occurrence of complications. With a mean of 2 years and 9 months follow-up (±28months), eight patients (11.1%) had tumor recurrence. Multifocal tumors as well as postoperative complications were associated with risk of recurrence. Three patients with positive tumor margins were monitored with no evidence of progression (with 71, 42 and 12 months of follow-up).
CONCLUSION: Our single-center retrospective study of partial nephrectomy for renal tumor showed medium-term oncological results similar to those reported in the total nephrectomy with the advantage of nephron preservation. The results of studies by conventional surgery such as that we report should be a benchmark for laparoscopic surgery.
