Detailed information of all patients who developed new neurological deficits after embolization or surgical treatment for spinal renal cell metastasis. Described is the location of the instable metastasis, time between embolization, and surgery (within 24h or within 24–48h between embolization and surgery) and time point of onset of new neurological deficit (either immediately after embolization, immediately after surgery or after surgery in case of immediate surgical treatment after embolization). Neurological deficits are described as sensory, motor, or incomplete or complete paraparesis according to the ASIA classification. Intraoperative blood loss is categorized into 250-ml steps, and blood products are reported as blood units. The surgical procedure was shown as a dorsal or ventral approach
