Trenton GH Lum

About

Trenton GH Lum is a urologic surgeon and researcher whose work focuses on advancing minimally invasive surgical techniques for prostate and kidney cancers, particularly through robot-assisted approaches. His most significant contributions center on the Retzius-sparing robot-assisted radical prostatectomy (RS-RALP), where he demonstrated that preserving the Retzius space during surgery significantly reduces the risk of postoperative inguinal hernia—a finding from his 2017 study that has garnered 46 citations. Lum also investigated how prostate volume affects surgical outcomes, showing that RS-RALP remains safe and effective across gland sizes. In kidney cancer, he has pioneered techniques for complex cases, including robot-assisted partial nephrectomy for totally endophytic and cystic renal tumors, with long-term follow-up studies (median 58–59 months) showing excellent oncologic and functional outcomes. His work on off-clamp partial nephrectomy and predictors of renal function recovery further refines surgical decision-making. With a publication record that includes studies on Gleason score upgrading and the safety of RS-RALP after prior prostate surgery, Lum has established himself as a careful, evidence-driven surgeon whose research directly improves patient outcomes in urologic oncology.
