A case of multilocular cystic renal cell carcinoma is reported, in which nephron-sparing surgery was done using microwave tissue coagulation. A 37-year-old man was referred to our outpatient clinic for a multilocular cystic tumor, 4.5 cm in diameter, in the middle-lower portion of the right kidney, which was detected by ultrasound during a health checkup. The patient had been found to have the same cystic mass on a CT done during another health checkup 1.5 years before. The tumor showed no growth during the 1.5-year period. With a diagnosis of multilocular cystic renal cell carcinoma, T2N0M0, in situ non-ischemic tumor enucleation was done using a microwave tissue coagulator (Microtaze, Heiwa Electronics Industry Inc., Tokyo). Operation time was 150 minutes and blood loss was 135 cc. The histological diagnosis was renal cell carcinoma, T2N0M0V0, cystic type, clear cell subtype, grade 1. Diagnostic imaging done postoperatively showed no sign of damage to renal function. In this report, the characteristics of multilocular cystic renal carcinoma are reviewed from the literature, and the advantages of nephron-sparing surgery for this type of renal tumor are discussed. In addition, an operative technique of tumor enucleation used in this case and the characteristics of Microtaze are introduced.
报告了一例多房囊性肾细胞癌病例，该病例采用微波组织凝固术进行了保留肾单位手术。一名37岁男性因健康检查时超声发现右肾中下部分有一个直径4.5厘米的多房囊性肿瘤，被转诊至我们的门诊。该患者在1.5年前的另一次健康检查中进行的CT检查中也发现了相同的囊性肿块。在这1.5年期间，肿瘤没有生长。诊断为多房囊性肾细胞癌，T2N0M0，采用微波组织凝固器（Microtaze，日本东京平和电子工业株式会社）进行原位非缺血性肿瘤剜除术。手术时间为150分钟，失血量为135毫升。组织学诊断为肾细胞癌，T2N0M0V0，囊性型，透明细胞亚型，1级。术后的诊断性影像学检查显示肾功能无受损迹象。在本报告中，从文献中回顾了多房囊性肾癌的特点，并讨论了保留肾单位手术治疗此类肾肿瘤的优势。此外，介绍了本病例中使用的肿瘤剜除术的手术技术以及Microtaze的特点。
