Objectives: To evaluate the role of three-dimensional (3D) reconstruction tumors and vessels of the kidneys in aiding the preoperative planning of partial nephrectomy.
Materials and Methods: Patients with renal tumors to be treated with partial nephrectomy were included. Each patient underwent a preoperative computed tomography (CT) survey, and the reconstruction of each patient’s 3D arteriography and 3D surface-rendered tumor was performed based on the CT images for preoperative surgical planning.
Results: A total of 6 patients, three with tumors of the right kidney and three with tumors of the left kidney, were enrolled in the study. The patients’ mean age was 49.33 ± 4.03 years (range: 45–57 years), and their mean tumor size was 4.4 ± 1.84 cm (range: 2.2–6.8 cm). Four underwent robot-assisted laparoscopic partial nephrectomies, one underwent a traditional laparoscopic partial nephrectomy, and one underwent a radical nephrectomy through laparotomy. Their average postoperative hospital stay was 6.7 days (range: 3–10 days). No intraoperative or postoperative complications were noted. The renal function was preserved in all the patients, and none of the patients exhibited evidence of local recurrence during more than 6 years of follow-up.
Conclusions: 3D arteriography fused with 3D surface-rendered tumor image navigation facilitates precise preoperative planning.
