ABSTRACT

Objective To evaluate different operative procedures for renal cell carcinoma. Methods 81 cases of renal cell carcinoma operated were reviewed.Radical nephrectomy was carried out for 73 case of which renal artery embolism was conducted for 38 before operation.Simple nephrectomy was carried out for 6 cases and enucleation of the tumor for 2. Results The pathological stu dies showed that 52 cases were clear cell carcinoma,19 cases of granular cell carcinoma,6 cases being a combination of the above two varieties,4 cases being cystic renal cell carcinoma.65 of 81 cases have been successfully followed up for 12～110 months.The 5 year survival rate for stage Ⅰ,Ⅱ,Ⅲ and Ⅳ tumors were 83.9%,78.9%,33.3% and 16.7% respectively. Conclusions Renal artery embolism before radial nephrectomy is essential for a successful operation to achieve a long term survival.Nephron sparing surgery for a small,localized low stage renal tumor is safe and effective.
