About
Wataru Obara is a leading urologic surgeon whose research centers on improving functional outcomes after robot-assisted laparoscopic prostatectomy (RALP) and partial nephrectomy. His most impactful work identifies preoperative membranous urethral length (MUL) as a key predictor of urinary continence recovery—a finding from a 2018 study of 204 patients that has garnered 29 citations and helped refine surgical counseling. Obara further advanced this area by using hierarchical cluster analysis to classify patients based on perioperative MUL changes, linking them to both incontinence and overactive bladder symptoms. Beyond prostate surgery, he has assessed long-term split renal function after robot-assisted partial nephrectomy using 99m-Tc DTPA scintigraphy, providing critical data on kidney preservation. Demonstrating innovation in surgical education, he showed that repeated virtual reality simulator training reduces 3D motion sickness in medical students—a practical step toward safer robotic surgery training. His work on reconstructing the Retzius space with peritoneal sutures to improve continence, and a case report on nephrectomy in severe scoliosis, highlight his commitment to expanding robotic surgery’s reach. With over 75 total citations, Obara’s research directly enhances patient quality of life and surgical precision.
