[Retroperitoneal laparoscopic radical nephrectomy in the treatment of renal cancer].

ABSTRACT

OBJECTIVE: To evaluate the safety and efficacy of retroperitoneal laparoscopic radical nephrectomy in the treatment of renal cancer. METHODS: The clinical data of 53 cases who underwent retroperitoneal laparoscopic radical nephrectomy were analyzed retrospectively. RESULTS: Fifty-two cases achieved successful retroperitoneal laparoscopic radical nephrectomy, a conversion to open surgery was required in one case because of severe adhesion. The operation time was 75 min to 220 min (mean, 125 min), the blood loss was 50 ml to 420 ml (mean, 120 ml), and the postoperative hospital stay was 6 d to 12 d. Complications occurred in 4 cases. Pathological examination showed that 47 cases were of renal clear cell carcinoma, 5 of chromophobe carcinoma, and 1 of cystic renal cell carcinoma. Follow-up for 1 month to 5 years showed no tumor recurrence and metastasis. CONCLUSION: Retroperitoneal laparoscopic radical nephrectomy is a safe and effective treatment for patients with stage T1 - 2N0M0 renal cell carcinoma.
