RETROPERITONEOSCOPIC RESECTION WITH PREOPERATIVE SELECTIVE EMBOLIZATION AND FLUORESCENCE VISUALIZATION OF VESSELS IN KIDNEY CANCER. ANALYSIS OF FUNCTIONAL RESULTS

Abstract

Aim of the study: kidney function evaluation in patients with localized renal cancer after retroperitoneoscopic kidney resection with preoperative selective embolization in comparison to standard kidney resection. Materials and methods. A total of 65 patients with localized renal cancer was divided into 2 groups: first – 40 patients who underwent standard renal resection with thermal ischemia (open or laparoscopic), second – 25 patients with retroperitoneoscopic kidney resection, and preoperative selective embolization and indocyanine green (ICG) fluorescent imaging. After 1, 6, and 12 months after the operation, the functional state of the kidneys was examined in all patients by means of determination of the serum creatinine and urea, glomerular filtration rate, creatinine clearance, urinary albumin excretion and imaging (renal ultrasound, contrast-enhanced CT or MRI) was performed. Results. The analysis shows significant benefit in postoperative kidney function after retroperitoneoscopic resection with preoperative vascular embolization and intraoperative ICG imaging. Conclusion. The analysis of the obtained data shows that kidney function after surgery for local kidney cancer in the case of retroperitoneoscopic resection with preoperative selective embolization of renal vessels compared to kidney resection using thermal ischemia is more gentle and therefore more functional for wide implementation.
