Retroperitoneoscopic versus open surgical radical nephrectomy for large renal cell carcinoma in clinical stage cT2 or cT3a: quality of life, pain and reconvalescence

Abstract

Objectives: To determine whether retroperitoneoscopic radical nephrectomy for large renal cell carcinoma in stage cT2 or cT3a is a feasible, safe and effective therapy option and if it shows any advantage regarding quality of life in comparison to open procedure.

Methods: 23 patients who underwent RPNx for tumor size greater than 7 cm (group 1) were matched and compared with 25 patients, who underwent ONx (group 2) for tumor with similar size characteristics. Patient and surgical data, QoL variables and complications were statistically analyzed.

Results: The median followup was 12 (range: 6-18) months for both groups. Group 1 had significantly (p < 0.001) less blood loss, shorter hospital stay, and shorter postoperative analgesic requirements. No conversion to open surgery was necessary, and no major complications requiring an invasive intervention occurred. Retroperitoneoscopic patients had significantly better QoL and pain scores postoperatively to 6 months (p < 0.001) and they return to baseline QoL status faster (p < 0.001).

Conclusions: RPNx for large RCC in stage cT2 or cT3a is a safe and efficacious procedure with good short-term outcome results and significantly shorter recovery of QoL variables.
