About
N. Grivas is a leading urologic surgeon and researcher whose work centers on advancing minimally invasive, image-guided surgical techniques for prostate and renal cancers. His major contributions focus on refining robot-assisted lymph node dissection and sentinel node biopsy (SNB) for prostate cancer, addressing the ongoing controversy around SNB’s diagnostic accuracy and oncologic safety. In his highly cited 2021 study (61 citations), Grivas demonstrated that while SNB offers good sensitivity and negative predictive value, its integration with extended pelvic lymph node dissection remains complex—a finding that has shaped clinical protocols for nodal staging. He also pioneered salvage robot-assisted renal surgery for local recurrence after ablation or resection, classifying techniques and reporting outcomes that offer new hope for patients with limited treatment options (24 citations). Grivas’s work is notable for its rigorous evaluation of both diagnostic value and safety profiles, bridging the gap between emerging imaging technologies and real-world oncologic outcomes. His research continues to influence the adoption of image-guided robotics in urologic oncology, making him a key voice in the evolution of precision surgery.
