3D MODELING AND PREOPERATIVE PLANNING FOR INDICATIONS TO LAPAROSCOPIC LASER PARTIAL NEPHRECTOMY WITHOUT WARM ISCHEMIA

Abstract

To determine indications for laparoscopic laser partial nephrectomy in a kidney’s tumor without ischemia we used 3D modeling and virtual planning using original computer program (RF patent No. 2055660462). The procedure was performed in 14 patients of average age 50.4 (39 - 68) years old, 6 (42.9%) men and 8 (57.1%) women, with a tumor of the right in 5 (35.7%) and left kidney - in 9 (64.3%) patients, average 23.7 (15 - 40) mm in size. The average operation time was 99.5 (80 - 131) min, the time of kidney resection was 28.6 (15 - 40) minutes, blood loss - 100.3 (50 - 250) ml. The time of hospitalization was 6.1 (5 - 9) days. Clear cell renal cell carcinoma G1 was detected in 9 (64.3%), G2 in 3 (21.4%), angiolipoma was found in 2 (14.3%) patients. No cases of positive surgical margin were observed. Preoperative 3D modeling and virtual operation planning made it possible to single out a group of patients who successfully underwent laser resection of the kidney without ischemia and hemostatic sutures.
