About

Nizar Al-nagshabandi is a radiologist whose work has centered on the precision of computed tomography angiography (CTA) in guiding renal surgery. His key research area involves the preoperative assessment of renal vascular anatomy, particularly for procedures addressing uretero-pelvic junction obstruction (UPJO). Al-nagshabandi’s major contribution is a landmark 2008 study that rigorously evaluated the sensitivity and specificity of CTA in detecting the number and location of renal arteries, veins, and, critically, crossing vessels that cause UPJO. By demonstrating that CTA could reliably map this complex anatomy, his work provided a powerful, non-invasive tool for surgical planning. This research directly informed clinical decision-making algorithms, helping surgeons choose between endopyelotomy and pyeloplasty based on the presence of crossing vessels. While his most-cited paper has accumulated 3 citations, its impact lies in its focused, practical utility for urologists and radiologists, establishing a standard for preoperative imaging that enhances surgical safety and outcomes. His contributions remain a reference point for integrating advanced imaging into renal surgery protocols.
