The objective of this study was to evaluate the effectiveness of CT-guided injection of 5% dextrose in water solution (D5W) into the retroperitoneum to displace organs adjacent to renal cell carcinoma.
An interventional radiology database was searched to identify the cases of patients who underwent CT-guided percutaneous radiofrequency ablation of biopsy-proven renal cell carcinoma in which D5W was injected into the retroperitoneal space to displace structures away from the targeted renal tumor. The number of organs displaced and the distance between the renal tumor and adjacent organs before and after displacement with D5W were assessed.
The cases of 135 patients with 139 biopsy-proven renal cell carcinomas who underwent 154 percutaneous CT-guided radiofrequency ablation procedures were found in the search. Thirty-one patients with 33 renal cell carcinomas underwent 36 ablation procedures after injection of D5W into the retroperitoneal space. Fifty-five organs were displaced away from renal cell carcinoma with this technique. The average distance between adjacent structures and renal cell carcinomas before displacement was 0.36 cm (range, 0.1-1.0 cm). The average distance between structures and adjacent renal cell carcinomas after displacement was 1.94 cm (range, 1.1-4.3 cm) (p < 0.0001). The average volume of D5W used to achieve organ displacement was 273.5 mL. No complications were associated with this technique.
CT-guided injection of D5W into the retroperitoneum is an effective method for displacing vital structures away from renal cell carcinoma.
本研究旨在评估 CT 引导下向腹膜后间隙注射 5%葡萄糖水溶液（D5W）以移位肾细胞癌附近器官的效果。
检索介入放射学数据库，以确定在经 CT 引导的经皮射频消融活检证实的肾细胞癌患者中，向腹膜后间隙注射 D5W 以将结构移位远离目标肾肿瘤的病例。评估 D5W 注射前后移位的器官数量和肾肿瘤与邻近器官之间的距离。
在搜索中发现了 135 例 139 个经活检证实的肾细胞癌患者的 154 例经皮 CT 引导射频消融术的病例。31 例 33 个肾细胞癌患者在腹膜后间隙注射 D5W 后进行了 36 次消融术。该技术可将 55 个器官从肾细胞癌中移位。在未移位之前，相邻结构与肾细胞癌之间的平均距离为 0.36cm（范围，0.1-1.0cm）。在移位后，结构与相邻肾细胞癌之间的平均距离为 1.94cm（范围，1.1-4.3cm）（p<0.0001）。用于实现器官移位的 D5W 的平均体积为 273.5mL。该技术无相关并发症。
CT 引导下向腹膜后间隙注射 D5W 是一种将重要结构从肾细胞癌中移位的有效方法。
