The results of organ-preserving treatment of patients with localized renal cell carcinoma according to the original methodology

The article presents results of treatment of patients with localized renal cell carcinoma using the original technique of open partial nephrectomy. This technique involves the use of intraoperative ultrasonoscopy to define and mark the boundaries of the tumor and the method of creating a zone of local ischemia to resection the tumor without the use of total renal ischemia. The developed methodology in the comparative analysis of the immediate and remote results significantly (p > 0.05) reduces the amount of intraoperative blood loss without increasing the duration of the operation, reduces the risk of development of acute disorders of renal function in the early postoperative period, without compromising kidney function in the late postoperative period. This technique is comparable to the classical open radical resection of the kidney, does not affect the overall, oncospecific and relapse-free survival.
