X-ray selective embolization and fluorescence imaging of renal vessels with retroperitoneoscopic resection in patients with localized kidney cancer

12 patients with local renalcell carcinoma of the kidney underwent retroperitoneoscopic resection of the kidney (ZERO ishemia) using intraoperative fluorescence imaging in the infrared region using Indocyanine green. At the preoperative stage, patients underwent super-selective x-ray vascular embolization.

66% of the patients were female, 34% - male. The average age of patients was 54, 3 years.

During operations, complications are not registered. There were two complications in the early postoperative period. In one case, the patient in the first day after the performed retroperitoneoscopic pole resection of the kidney with suturing of the pyelocaliceal system noted abundant hematuria. The indicated complications were subsequently stopped conservatively. In the second case, after the performed retroperitoneoscopic frontal resection of the kidney, the formation of an external urinary fistula is noted. The indicated complications did not require surgical correction and was stopped conservatively on the seventh postoperative day.

The operation time averaged 89 minutes (54 minutes - 124 minutes). The level of intraoperative blood loss is an average of 70 ml. (from 20 to 200 ml). The average hospital stay was 3,9 days. In 11 cases, in a morphological study in patients, clear cell renal cell carcinoma (pT1-2acN0M0R0G1-3) was verified, іn one case - kidney angiolipoma was verified.
