About
Masayoshi Okumi is a leading figure in robotic urologic oncology, with a primary focus on refining surgical techniques for kidney and prostate cancers. His work centers on robot-assisted laparoscopic partial nephrectomy (RAPN), where he has systematically compared surgical approaches—such as transperitoneal versus retroperitoneal access and tumor enucleation versus resection—to optimize patient outcomes. A key contribution is his investigation of the peritumoral pseudocapsule in renal cell carcinoma, identifying predictive factors for its absence to guide surgical planning. Okumi’s research also extends to complex cases, including radical prostatectomy and cystectomy in kidney transplant recipients, demonstrating the safety and feasibility of robotic surgery in immunocompromised patients. His most cited paper (34 citations) compares surgical outcomes for lateral renal tumors, while a 2017 study (26 citations) established the utility of the Surface-Intermediate-Base margin score in guiding RAPN. With over 125 total citations across his top ten papers, Okumi’s work has significantly advanced evidence-based, minimally invasive nephron-sparing surgery, particularly for challenging tumor locations and patient populations.
