Abstract：
Peritoneal carcinomatosis associated with renal cell carcinoma is an infrequent entity, usually associated with large renal masses, and with a very rare presentation after surgery of localized renal tumors. Our objective is to review the literature and analyze the factors involved in the development of peritoneal carcinomatosis after laparoscopic partial nephrectomy in localized tumors.
We present our experience with two cases of peritoneal carcinomatosis after laparoscopic partial nephrectomy. We reviewed the literature and analyzed the factors associated with the development of peritoneal carcinomatosis after laparoscopic partial surgery in renal cell carcinoma.
Between 2005-2018, 225 patients underwent laparoscopic partial nephrectomy for localized renal neoplasia in our service. Two patients developed peritoneal carcinomatosis during follow-up, at 1.5 and 7 years after surgery. Few cases of postoperative peritoneal carcinomatosis for renal neoplasia have been described in the literature, being more frequently associated with large renal masses, with multiple metastases at diagnosis, with a poor prognosis. The dissemination of tumor cells during surgery, direct tumor extension or metastasis by hematogenous route, are among the factors involved in the development of this condition.
Peritoneal carcinomatosis after laparoscopic partial nephrectomy constitutes a very rare event. However, it should be taken into consideration, and, since it is the only factor we can influence, we must maximize precautions during the surgical act, following oncological principles.

摘要：
与肾细胞癌相关的腹膜癌病是一种罕见的实体，通常与大的肾脏肿块有关，并且在局部肾肿瘤手术后非常罕见。我们的目的是回顾文献并分析腹腔镜局部肾部分切除术后腹膜癌发展的相关因素。
我们介绍了两例腹腔镜肾部分切除术后腹膜癌的经验。我们回顾了文献，并分析了腹腔镜肾细胞癌部分手术后腹膜癌发展的相关因素。
在2005-2018年间，我们的服务中有225例患者接受了腹腔镜肾部分切除术治疗局限性肾瘤变。两名患者在随访期间发展为腹膜癌，在手术后1.5年和7年。文献中很少描述肾瘤变术后腹膜癌的病例。更经常与大的肾脏肿块相关，诊断时多发转移，预后不良。手术过程中肿瘤细胞的播散，通过血行途径直接肿瘤扩展或转移，是这种情况发展的因素之一。
腹腔镜肾部分切除术后的腹膜癌病是非常罕见的事件。然而,应该考虑到这一点，and,因为这是我们唯一能影响的因素，我们必须在手术期间最大限度地采取预防措施，遵循肿瘤学原则。
