Abstract:
【Objective】 To analyze the position of the feeding artery entering the renal cell carcinoma (RCC) with 3D Slicer software, so as to explore the distribution pattern of the tumor artery and to provide an anatomical basis for the accurate surgical resection. 【Methods】 The clinical data of RCC patients who underwent partial nephrectomy in the Department of Urology, The Second Affiliated Hospital of Xi'an Jiaotong University during Jan.2021 and Jun.2022 were collected.The preoperative renal artery CT angiography data were imported into 3D Slicer software in DICOM format to construct the relative positions of tumor-feeding artery from horizontal, sagittal and coronary planes.The number and distribution of tumor feeding arteries in each plane were analyzed. 【Results】 A total of 112 patients (59 male and 53 female) with single tumor were involved.RENAL score was 4-10.The tumor stages were T1a in 58 cases, T1b in 48 cases, and T2a in 6 cases.Among them, 38 cases (33.93%) had 1 tumor artery, 53 cases (47.32%) had 2 tumor arteries, and 21 cases (18.75%) had 3 tumor arteries.Of these 207 tumor arteries, 22 (10.63%) entered the tumor through the superficial part of the tumor bed, and 185 (89.37%) through the deep part. 【Conclusion】 In localized RCC, nearly 90% of the feeding arteries enter the tumor from deep part of the tumor bed, which provides an anatomical basis for accurate tumor resection and wound suture in partial nephrectomy.
