About

Etienne Xavier Keller is a urologic surgeon and researcher whose work centers on advancing minimally invasive surgical techniques for stone disease and prostate cancer. His major contributions lie in optimizing endourologic technologies and refining surgical outcomes. Keller’s 2019 study on next-generation fiberoptic and digital ureteroscopes (44 citations) has helped shape modern endoscopic practice, while his investigation of Ho:YAG laser lithotripsy in non-contact mode (20 citations) provided critical insights into improving stone ablation efficiency through fiber-to-stone distance optimization. In prostate cancer, his 2018 analysis of unifocal versus multifocal positive surgical margins after robot-assisted radical prostatectomy (32 citations) offered valuable prognostic guidance for surgeons. Keller also led a comprehensive 2022 systematic review and meta-analysis comparing PCNL, laparoscopic, and robotic pyelolithotomy for large renal stones (24 citations), helping clarify the relative merits of these approaches. His ongoing work on robot-assisted extended pelvic lymph node dissection (2024) continues to refine understanding of anatomical yields and metastatic patterns. With a research portfolio that bridges technological innovation and clinical outcomes, Keller has established himself as a thoughtful contributor to evidence-based urologic surgery.
