About
Zachary Klaassen is a leading urologic oncologist and robotic surgeon whose research has reshaped surgical approaches to prostate, kidney, and bladder cancers. His landmark work on Retzius-sparing robotic-assisted laparoscopic radical prostatectomy (RALP) demonstrated that this technique preserves anterior pelvic structures, yielding superior early continence outcomes without compromising oncologic safety—a finding supported across multiple studies totaling over 100 citations. Klaassen also authored a pivotal meta-analysis comparing robot-assisted to open radical cystectomy (81 citations), providing critical evidence on perioperative and oncologic equivalence. In complex stone disease, he pioneered robot-assisted anatrophic nephrolithotomy and championed the zero-fragment nephrolithotomy concept, achieving complete stone clearance with minimal morbidity. His contributions extend to venous thromboembolism prophylaxis in prostate cancer surgery, offering procedure-specific guidelines that improve patient safety. With over 300 publications, Klaassen has advanced minimally invasive techniques across the urologic spectrum, from donor nephrectomy to salvage prostatectomy and retroperitoneal lymph node dissection for testis cancer. His work consistently balances technical innovation with rigorous outcomes analysis, making him a key voice in evidence-based robotic urology.
