Intraoperative mapping of renal lymphatic drainage: technique and application in a porcine model.

摘要: Background and Purpose: The use of lymphadenectomy in renal-cell carcinoma (RCC) is controversial. Proponents argue that improves survival, whereas opponents challenge the procedure on basis its morbidity variable lymphatic drainage kidney. Intraoperative gamma probes have been used to guide resection radiolabeled sentinel nodes cancers breast, penis, head neck melanoma. Our goal applying this technique RCC improve detection limit sampling lymph during lymphadenectomy. This preliminary study a porcine model evaluated feasibility transit time tracer injected into Materials Methods: Data were collected four 40-kg Yorkshire pigs. right kidney was exposed through flank incision. Using both blue dye technetium-99m, mapping performed with assistance an intraoperative probe (Neoprobe®). Remote cervical lymp...
