About

Dr. Masashi Inui is a pioneering urologic surgeon whose work sits at the intersection of robotic surgery, transplantation, and oncology. His most significant contributions involve adapting advanced robotic techniques for complex, high-stakes procedures in challenging patient populations. Notably, he performed the first robotic renal autotransplantation outside of North America, a landmark case for a 38-year-old woman with ureteral stenosis and suspected ureteropelvic junction obstruction. This work, cited 16 times, demonstrated the feasibility of robotic dissection in desmoplastic tissue. Dr. Inui is also a leading voice in robot-assisted radical prostatectomy (RARP), having authored a key study on predictors of long-term urinary incontinence following the procedure, which analyzed outcomes in 121 patients. His research extends to transplant oncology, where he has investigated the management of prostate cancer in living kidney donor candidates and performed robot-assisted prostatectomy in Asian renal transplant recipients (17 citations). More recently, he has explored rare, aggressive malignancies, reporting a case of G-CSF-producing bladder carcinoma. Through these diverse contributions, Dr. Inui has advanced the safety and scope of robotic urologic surgery, particularly for patients with complex surgical histories.
