We report our clinical findings on 7 tumors in 5 patients who underwent successful enucleation of renal tumor with a microwave tissue coagulator. All patients presented with incidentally-found renal tumor on ultrasonography or computed tomography. One patient had bilateral renal tumors. The mean size of the renal tumor was 2.5 cm (Range 1.0-5.2 cm). One patient had a tumor larger than 5 cm, and was found to have renal insufficiency preoperatively. Four cases were clinically diagnosed as T1aN0M0. In all patients, the renal tumor was enucleated with a microwave tissue coagulator successfully without renal pedicle clamping. The mean operative time and blood loss were 241 minutes and 788 ml, respectively. The pathological diagnosis was renal cell carcinoma in all cases. Although 2 patients had preoperative renal insufficiency, there were no serious postoperative complications and no evidence of loss of renal function as a result of this operation. Our findings suggest that renal tumors can be enucleated with a microwave tissue coagulator safely and successfully without damaging renal function.
我们报告了5例患者7个肿瘤的临床研究结果，这些患者均使用微波组织凝固器成功地进行了肾肿瘤剜除术。所有患者均通过超声或计算机断层扫描偶然发现肾肿瘤。1例患者患有双侧肾肿瘤。肾肿瘤的平均大小为2.5厘米（范围1.0 - 5.2厘米）。1例患者的肿瘤大于5厘米，术前发现肾功能不全。4例临床诊断为T1aN0M0。所有患者均使用微波组织凝固器成功进行了肾肿瘤剜除术，未夹闭肾蒂。平均手术时间和失血量分别为241分钟和788毫升。所有病例的病理诊断均为肾细胞癌。虽然2例患者术前存在肾功能不全，但术后无严重并发症，且无证据表明该手术导致肾功能丧失。我们的研究结果表明，使用微波组织凝固器可以安全、成功地进行肾肿瘤剜除术，而不会损害肾功能。
