Abstract：
OBJECTIVES:To evaluate the efficacy of laparoscopic radical nephrectomy for patients with small renal cell carcinoma by comparing the clinical results of patients treated laparoscopically with those of patients treated with traditional open radical nephrectomy. METHODS:Of 100 patients with localized, small (less than 5 cm in diameter) renal cell carcinoma treated by the same surgical team between 1992 and 1998, 60 patients underwent laparoscopic radical nephrectomy and 40 underwent open radical nephrectomy. Of the 60 laparoscopically treated patients, the first 11 and the most recent 34 patients were operated on transperitoneally and the other 15 retroperitoneally. RESULTS:The mean operative time of the laparoscopically treated patients was longer than that of the open nephrectomy patients (5.2 versus 3.3 hours, P<0.001). The mean blood loss of the laparoscopically treated patients was less than that of the open nephrectomy patients (255 versus 512 mL, P<0.001). One laparoscopically treated patient needed conversion to open surgery. The time to full convalescence of the laparoscopically treated patients was shorter than that of the open nephrectomy patients (23 versus 57 days, P<0.001). Two of the 59 laparoscopically treated patients and 1 of the 40 open nephrectomy patients had metastatic disease. The former 2 are alive with stable disease and the latter died of progressive disease 11 months after surgery. The 5-year disease-free rate was 95.5% in laparoscopy patients and 97.5% in open nephrectomy patients (P = NS). CONCLUSIONS:Laparoscopic radical nephrectomy is a less invasive alternative to open surgery for patients with localized small renal cell carcinoma.
