A new method to visualize and to spare the ureters during SBRT for oligo metastatic patients

Technical Innovations & Patient Support in Radiation Oncology, 2021
This article describes a ureter-sparing procedure used to treat lymph node metastases with SBRT. We delivered 35 Gy in 5 fractions of 7 Gy to patients with lesions located less than 7 mm from the ureters using a urography CT scan for planification.
