About
Armando J. Lorenzo is a leading pediatric urologist whose research has significantly advanced minimally invasive surgical techniques for complex urological conditions in children. His major contributions center on robotic-assisted and laparoscopic pyeloplasty for ureteropelvic junction obstruction (UPJO), where his landmark 2009 systematic review and meta-analysis—cited over 200 times—established comparative outcomes on operative time, hospital stay, complications, and success rates. He further refined surgical approaches through a meta-analysis comparing retroperitoneal versus transperitoneal laparoscopic and robot-assisted pyeloplasty, providing evidence-based guidance for surgical planning. Beyond UPJO, Lorenzo has explored rare conditions such as nutcracker syndrome, outlining diagnostic and therapeutic strategies, and investigated postoperative complications like prolonged urinary retention after ureteral reimplantation. His work also includes outcomes of laparoscopy-assisted appendicovesicostomy creation and retroperitoneal laparoscopic heminephrectomy in children, demonstrating his breadth in pediatric reconstructive urology. With over 230 cumulative citations across his most influential papers, Lorenzo’s research has shaped clinical decision-making and improved surgical outcomes for young patients.
