Malignant tumor resection in the solitary kidney: use of hypothermic hyperosmolar renal preservation method

In 4 out of 8 patients with a malignant tumor in a single or in a solitary kidney, partial nephrectomy was performed under ischemic conditions. To avoid severe ischemic damage the kidneys have been flushed with a cold hyperosmolar intracellular-type electrolyte solution. In all cases excellent kidney function was obtained postoperatively and no tumor recurrence was observed 18 months to 5 years later.
