Gross hematuria is a distressing symptom for patients with upper urinary tract urothelial cancers (UTUC). Invasive procedures are usually employed to control hematuria, including surgical resection, endoscopic laser ablation, and percutaneous nephroscopic resection. Stereotactic body radiation therapy (SBRT) is a non-invasive, targeted radiation therapy technique frequently applied in curative and palliative settings. It involves a short treatment course (3-5 fractions), maximum dose delivery to the target lesion, and optimal sparing of the surrounding organs. SBRT application in the management of UTUC is usually limited due to the risk of kidney and bowel injury.
