About

Dr. Arman Walia is a leading urologic oncologist whose research focuses on optimizing surgical outcomes for upper tract urothelial carcinoma (UTUC), with a particular emphasis on the role of lymph node dissection (LND) in robotic nephroureterectomy. His landmark study, "Outcomes of Lymph Node Dissection in Nephroureterectomy in the Treatment of Upper Tract Urothelial Carcinoma: Analysis of the ROBUUST Registry," published in 2022, has already garnered 29 citations, underscoring its immediate impact on clinical practice. By leveraging the multi-institutional ROBUUST (RObotic surgery for Upper Tract Urothelial Cancer Study) registry, Dr. Walia provided critical evidence demonstrating that LND during robotic nephroureterectomy may improve staging and potentially survival outcomes in UTUC patients. This work has helped clarify the oncologic benefits of lymphadenectomy in a procedure where its utility was previously debated. Dr. Walia’s contributions are shaping evidence-based guidelines for minimally invasive management of upper tract malignancies, making him a rising authority in urologic oncology whose research bridges surgical technique with meaningful patient outcomes.
