Retroperitoneoscopic radical nephrectomy by the posterior lumber approach for renal-cell carcinoma associated with chronic renal failure.

摘要

PURPOSE: To evaluate the efficacy and invasiveness of retroperitoneoscopic radical nephrectomy for renal-cell carcinoma (RCC) in patients with chronic renal failure (CRF), a group known to have relatively high surgical risk. PATIENTS AND METHODS: Between May 1996 and September 1999, six CRF patients maintained on hemodialysis underwent retroperitoneoscopic radical nephrectomy for clinically localized RCC by the posterior lumber approach. The excised kidneys were evacuated via a posterior skin incision (5 cm) between two port sites; the muscle layers were not incised. RESULTS: The procedure was completed in all patients with no major complications. The mean operative time was 162 (range 135-210) minutes, and the estimated blood loss was 58 (15-100) mL; none of the patients required a blood transfusion. Regular hemodialysis was restarted on postoperative day 2 or 3. CONCLUSIONS: This procedure seems to be minimally invasive and suitable for the treatment of small RCC in atrophic kidneys, especially in patients with CRF.
