多房性囊性肾瘤的诊断与治疗

目的提高对多房性囊性肾瘤的认识,探讨其合理的诊治原则。方法回顾分析4例本病患者的临床资料,结合文献讨论其诊断与治疗。结果4例均行手术治疗,肾部分切除1例,肾切除3例。术后随访2~10年,残肾及对侧肾脏均未见肾瘤。结论本病术前诊断依靠B超、CT,手术是治疗主要手段。病变超过半肾,对侧肾功能正常者,建议做一侧肾切除术;病变局限小于半肾可选择肾部分切除术,但切缘宜超出病变至少0.5cm。

多房性囊性肾瘤1例报告并文献复习

多房性囊性肾瘤（multilocular cystic nephroma,MCN）是一种临床上较罕见的肾脏原发良性肿瘤,因其无特异的临床表现,术前常常无法明确诊断,与其他肾脏囊性病变的鉴别诊断较为困难,如多囊肾、多发性肾囊肿、囊性肾癌等。我科于2011年收治1例 MCN,现报告如下,以进一步提高对该病的认识。     

多房性囊性肾瘤的诊断与治疗（附4例报告）

目的提高对多房性囊性肾瘤（MLCN）的诊断和治疗水平。方法回顾性分析4例MLCN患者的临床资料。男2例，女2例。年龄41-72岁，平均53岁。主要表现为血尿、腰部钝痛、肾绞痛和肾区肿块。分析其B超、IVU、CT、MRI检查所见征象，并与手术、病理所见对照。结果4例患者均行开放性手术治疗后痊愈。其中行肾切除3例，肾部分切除1例。患者术后随访6-18个月木发现复发。结论影像学检查是MLCN的重要检查手段，保留肾单值的肿瘤切除术是本病的首选治疗方法。多房性囊性肾瘤为良性肿瘤，术后均能获得痊愈。

Multilocular cystic nephroma: A case report and review of the literature

Multilocular cystic nephroma is a rare cystic renal tumor, which is benign and has an excellent prognosis. However, preoperative diagnosis is challenging and is made exclusively by pathological findings. We reported a 41-year-old woman with chronic flank pain, and abdominal computed tomography revealed a multiloculated renal cystic tumor. The possibility of a cystic variant of renal cell carcinoma could not be excluded. Laparoscopic radical nephrectomy was performed, and diagnosis of multilocular cystic nephroma was made. In this report, we describe the clinical presentation, radiological finding, and histopathology of this case.     

多房囊性肾细胞癌手术治疗的预后特点分析

目的探讨多房囊性肾细胞癌患者手术治疗的预后特点。方法回顾性分析482例肾癌患者中22例多房囊性肾细胞癌患者资料，分析其手术治疗的预后特点。多房囊性肾细胞癌占同期肾癌病例的4．56％，男女比例为2．67：1．00，年龄32～74岁，平均47岁。结果22例患者中行肾癌根治术18例，行肾部分切除术4例。肿瘤直径1．8～11．0cm，平均4．8cm。其中透明细胞癌21例，透明细胞癌与颗粒细胞癌混合型1例；pT1N0M019例，pT2N0M02例；pT3bN0M01例；G15例，G217例。失访2例，20例获随访，随访时间9～56个月，平均27．6个月。其中1例因肝硬化、上消化道出血死亡，无瘤存活21例。结论多房囊性肾癌是肾癌的一种特殊类型，多为肾偶发癌，病理分期分级低，预后与肿瘤大小无关，手术治疗效果满意，预后佳。     

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.
