囊性肾癌10例分析

目的：探讨提高囊性。肾癌的诊治水平的方法。方法：对10例囊性。肾癌的临床资料进行回顾性分析。术前CT诊断囊性。肾癌8例,复杂性。肾囊肿1例,单纯性。肾囊肿1例。10例均行根治性。肾切除术。结果：术后病理检查均为囊性。肾透明细胞癌,其中。肾癌囊性坏死5例,多房性囊性。肾癌2例,单纯性囊肿恶变3例。随访8例,7例术后生存至今,生存时间1个月～6年,1例术后6个月死于脑血管意外。结论：囊性。肾癌有其独特的临床、影像学及病理学特征,确诊者宜行根治性。肾切除。     

腹腔镜手术治疗囊性肾癌的临床分析与体会

目的:总结腹腔镜手术治疗囊性肾癌(CRCC)的临床经验,提高临床诊治水平。方法:回顾性分析2014年10月～2018年5月我院收治的14例术前影像学诊断为CRCC并接受腹腔镜手术治疗的患者的临床资料,并定期随访。14例肾脏囊性疾病通过螺旋CT、超声检查或MRI初步诊断为CRCC,其中Bosniak分级Ⅱ、ⅡF、Ⅲ、Ⅳ级肾脏囊性疾病分别为4、2、6、2例。9例行腹腔镜保留肾单位手术(LNSS);3例行腹腔镜根治性肾切除术(LRN);1例行腹腔镜肾囊肿去顶减压术;1例行腹腔镜肾囊肿去顶减压术,术后病理考虑恶性病变再次行LNSS。结果:14例患者术后均恢复良好。术后病理检查结果显示,6例诊断为低度恶性潜能多房囊性肾癌(MCRNLMP),4例诊断为肾细胞癌囊性变(RCCC),3例诊断为单纯性肾囊肿,1例诊断为多房囊性肾瘤(MLCN)。其中11例CRCC中,T_(1a)N_0M_0期4例,T_(1b)N_0M_0期3例,T_(2a)N_0M_0期3例,T_(2b)N_0M_0期1例。随访2～46个月,其中1例RCCC患者术后9个月复发,其余均无复发和转移。结论:术前影像学诊断的CRCC病理类型多样,诊断较为困难,但Bosniak分级可以作为肾囊性肿瘤的诊断与治疗的重要依据。LNSS可作为治疗CRCC的优先选择方案,MCRNLMP预后良好,与临床分期及肿瘤体积无关,但RCCC预后不良,应根据术后病理个体化管理随访。     

后腹腔镜囊肿去顶减压术治疗肾脏囊性疾病57例报告

目的:探讨后腹腔镜囊肿去顶减压术治疗肾脏囊性疾病的临床疗效及手术方法。方法:对57例肾脏囊性疾病患者行后腹腔镜囊肿去顶减压术,其中单纯性肾囊肿51例,多囊肾6例,回顾分析相关资料。结果:57例手术均获成功,无严重并发症发生。镜下操作时间单纯性肾囊肿15～35 min,多囊肾90～120 min;单纯性肾囊肿术中出血5～20 ml,多囊肾30～60 ml。术后随访3～24个月,单纯性囊肿无复发;多囊肾患者术后腰部胀痛缓解,3例合并肾功能不全的患者肾功能改善。结论:后腹腔镜囊肿去顶减压术治疗肾脏囊性疾病患者创伤小,康复快,疗效确切,可作为治疗肾脏囊性疾病的首选方法。     

多房性囊性肾癌与肾癌出血坏死囊性变的临床比较

目的:探讨多房性囊性肾癌(MCRCC)与肾癌出血坏死囊性变(NCRCC)的临床特点,提高两种疾病的诊治水平。方法:对MCRCC及NCRCC各10例的临床资料进行对比研究,并对其囊壁增厚、强化特点等CT征象以及病理分级进行统计学分析。结果:两组患者无特异性,NCRCC组最重要的CT征象为囊壁及分隔局部结节或肿块,与MCRCC组相比差异有统计学意义(P<0.01)。MCRCC组病理分级低,与NCRCC组相比差异有统计学意义(P<0.05)。结论:MCRCC与NCRCC是两种生物学行为不同的肾癌类型,应注意鉴别,鉴别主要依靠影像学检查。MCRCC恶性程度低,预后较好。     

囊性肾癌的诊治及预后(附31例报告)

目的提高囊性肾癌的诊治水平，提高对于囊性肾癌的认识。方法回顾性分析1994年6月-2004年6月收治的31例囊性肾癌患者的流行病学、病理学、临床表现、影像学特征及临床治疗资料，并与TNM分期构成与囊性肾癌组相同的21例非囊性肾癌比较预后。结果囊性肾癌无特征性的临床表现，术前影像学检查可以提供诊断线索，经病理确诊肾癌囊性变19例，多囊性肾癌9例，单纯性囊肿癌变3例。17例行根治性肾切除术，14例行单纯性肾切除术。术后21例获得随访，生存时间平均38个月。总体上与非囊性肾癌的预后尤统计学差异。站论囊性肾癌是一类在影像学和大体病理上具有囊性改变的肾癌的统称，由3种病理学类型构成，术前正确鉴别各亚型是选择手术方式和判断预后的关键。

多房性囊性肾癌一例报告及文献复习

Objective To discuss the diagnosis and outcome of multilocular cystic renal cell car-cinoma. Methods The clinic data of 1 case of multilocular cystic renal cell carcinoma were reviewed with its clinical manifestation, imaging, pathology and therapy in our hospital. The male patient aged 49 was incidentally found to have a right renal tumor. The CT scan showed a multiloeular cystic tumor in the low pole of the right kidney with a clear outline. The thin septa were found in the tumor, which were enhanced in the enhancement CT scan. The enhancement MRI showed the cystic wall was en-hanced. Results The patient received a partial nephrectomy as his treatment. The pathological char-acteristics were as following: the multilocular cystic tumor was about 3 cm×2 cm×2 cm with clear serosity in it. The cystic wall was smooth with the width of 0.1-0.2 cm. Most of the cystic cavities were covered by monostratified or stratified cubic clear cells, and some were covered by squamous epi-thelium or no epithelium at all. The septum was composed of collagen fiber, and clear cells were found in it. The clear cells form small collections but do not form expansile nodules. The final pathological diagnosis was multilocular cystic renal cell carcinoma. The follow-up was 20 months, without local re-currence or distant metastasis was found. Conclusions Multilocular cystic renal cell carcinoma (MCRCC) is a rare variant of renal cell carcinoma with a good prognosis. MCRCC is an uncommon tumor of the kidney composed of multiple cysts with clear cells in the septa indistinguishable from grade I renal cell carcinoma. Most patients are asymptomatie and the tumors are discovered inciden-tally. The preoperative diagnosis of MCRCC immediately depends on imaging studies. Pathology is the key to diagnosis.
