About

Dr. R. Ernest Sosa is a pioneering urologic surgeon whose research has fundamentally advanced minimally invasive treatments for kidney and urinary tract disorders. His primary focus lies in laparoscopic and robot-assisted surgery, particularly for ureteropelvic junction (UPJ) obstruction. Dr. Sosa’s major contribution is the validation and popularization of robot-assisted laparoscopic pyeloplasty as a safe, effective alternative to traditional open surgery. His landmark 2005 paper, “Robot-Assisted Laparoscopic Dismembered Pyeloplasty: A Combined Experience” (93 citations), demonstrated that robotic technology could overcome the steep learning curve of pure laparoscopy, making complex reconstructive procedures more accessible. This work, alongside his 2003 review on minimally invasive management of UPJ obstruction, helped establish robotic pyeloplasty as a gold standard. Dr. Sosa also examined training trends in urologic laparoscopy (33 citations), highlighting how residency and fellowship programs shape surgical adoption. His collaborative “Combined New York Experience” studies further underscored the reproducibility of robotic techniques across institutions. With hundreds of cumulative citations, Dr. Sosa’s research has directly shaped modern urologic practice, enabling surgeons worldwide to offer patients less invasive, more precise care with faster recovery times.
