目的探讨保留肾单位的肾癌手术治疗方法和疗效.方法 66例行保留肾单位的肾癌切除手术,肿瘤直径2.0～6.5 cm,平均4.1cm;肿瘤位于肾上极19例,肾中部17例,肾下极30例.TNM分期:T1a NOMO42例,T1b NOMO23例,T3NOMO1例.透明细胞癌59例,颗粒细胞癌6例,乳头状肾细胞癌1例.结果肾部分切除术66例,术中阻断肾蒂血管48例.所有病例手术切缘均为阴性.术后出现并发症5例,围手术期有一例患者出现急性肾功能衰竭.65例肾细胞癌患者获随访,平均随访时间61.4个月,5年生存率及5年无瘤生存率分别为98.5%和93.8% 结论肾癌保留肾单位手术是治疗局限性肾癌的有效方法.

Obiectives To investigate the method and effect of nephron-sparing surgery in treatment of renal cell carcinoma．Methods NSS of RCC was performed in 66 patients．The mean tumor size was 4．1 cm in diameter(range 2．0～6．5 cm)．Nineteen tumors were at the upper pole of kidney，17 at the middle and 30 at the lowerpole．Fourty two cases were classified to have T1 ANOMO stage tumor and 23 cases were T1bNOMO tage，one case was T3NOMO stage according to TNM classification．Pathological examination showed that 59 cases had clear cell carcinoma，6 had granule cell carcinoma，and one had papillary renal cell carcinon'la．Results Sixty six were treated with partial nephrectomy．The renal vessel was chmped in 48 cases intraoperative．Surgical margins were negative in all cases．Five patients had postoperative complications and one perioperative acute renal failure occurred．Sixty five were followed for mean 61．4 months．The overall and disease-free 5-year survivalrates were 98．5％and 93．8％ Respeetively．Conclusions Nss is an effective and safe procedure for RCC patients under specific circum stunces．
