About

Andreas Dellis is a distinguished urological surgeon and researcher whose work centers on the surgical management of complex stone disease and upper urinary tract obstructions. His most-cited study, "Ureteropelvic obstruction and renal stones: etiology and treatment" (2014, 43 citations), provides a comprehensive framework for understanding the interplay between anatomical anomalies and stone formation, offering evidence-based guidance for combined endoscopic and reconstructive approaches. This work has become a key reference for clinicians treating concurrent ureteropelvic junction obstruction and nephrolithiasis. Dellis’s contributions extend to refining minimally invasive techniques, including laparoscopic pyeloplasty and retrograde intrarenal surgery, improving outcomes for patients with challenging stone burdens. His research bridges the gap between etiology and practical surgical decision-making, earning him recognition as a thought leader in endourology. With a career dedicated to advancing urological care, Dellis continues to influence both clinical practice and surgical training, making his work essential reading for residents and specialists alike.
