Laparoscopic radical nephrectomy is an established treatment for patients with clinical T1 renal cell carcinoma who are unsuitable for nephron-sparing surgery. In this review we summarize the expanding indications for laparoscopic nephrectomy, including large tumors, locally advanced disease, venous thrombi and cytoreductive surgery.
Laparoscopic nephrectomy remains the foremost conventional laparoscopic procedure in urologic surgery. Multiple studies have demonstrated the feasibility of laparoscopic radical nephrectomy for stage T2 tumors, showing less morbidity and earlier return to activity compared to the open approach. Confirmation of durable oncologic control requires randomized prospective trials with longer follow-up. With growing experience, laparoscopic surgery has been extended to patients with renal cell carcinoma associated with limited local invasion and lymph node metastases. Experimental studies demonstrate the technical feasibility of laparoscopic radical nephrectomy in the presence of renal vein and inferior vena cava thrombi. In well-selected patients with metastatic renal cell carcinoma, laparoscopic cytoreductive nephrectomy can be performed safely, with less morbidity than open nephrectomy.
Minimally invasive surgery results in significantly less postoperative morbidity than does open surgery. The intermediate oncologic outcomes of laparoscopic radical nephrectomy for advanced renal cell carcinoma are comparable to those historically achieved with open radical nephrectomy. Longer follow-up is needed to confirm survival equivalence.
腹腔镜根治性肾切除术是治疗不适于保留肾单位手术的临床T1期肾细胞癌患者的既定方法。在本综述中,我们总结了腹腔镜肾切除术不断扩大的适应证,包括大肿瘤、局部进展性疾病、静脉血栓形成和减瘤手术。
腹腔镜肾切除术仍然是泌尿外科手术中最重要的传统腹腔镜手术。多项研究已证明腹腔镜根治性肾切除术治疗T2期肿瘤的可行性,与开放手术相比,其发病率更低且恢复活动更早。要确认长期的肿瘤学控制效果,需要进行随访时间更长的随机前瞻性试验。随着经验的积累,腹腔镜手术已扩展至局部侵犯有限和伴有淋巴结转移的肾细胞癌患者。实验研究证明了在存在肾静脉和下腔静脉血栓的情况下进行腹腔镜根治性肾切除术的技术可行性。在精心挑选的转移性肾细胞癌患者中,腹腔镜减瘤性肾切除术可安全实施,其发病率低于开放肾切除术。
微创手术导致的术后发病率明显低于开放手术。腹腔镜根治性肾切除术治疗晚期肾细胞癌的中期肿瘤学结果与既往开放根治性肾切除术的结果相当。需要更长时间的随访来确认生存等效性。
