Patterns of lymphatic metastases in upper tract urothelial carcinoma and proposed dissection templates
Carcinoma, Transitional Cell
Lymph Node Excision
Upper tract urothelial carcinoma has characteristic patterns of lymph node metastases depending on the side and anatomical location of the primary tumor, including right-to-left migration and involvement of interaortocaval nodes in the setting of proximal disease. Standardized dissection templates should be prospectively evaluated in multicenter trials to assess morbidity and potential clinical benefit.
