About

Urmila Khettry is a biomedical researcher whose work sits at the intersection of interventional radiology and minimally invasive surgery. Her most cited contribution, "Endovascular Temporary Vessel Occlusion with a Reverse-thermosensitive Polymer for Bloodless Minimally Invasive Renal Surgery" (2010), introduced a novel approach to achieving temporary, reversible vessel occlusion during renal procedures. This technique leverages a reverse-thermosensitive polymer—a material that transitions from liquid to gel at body temperature—to create a temporary "plug" that can be dissolved on demand, enabling bloodless surgical fields without permanent vessel damage. With 14 citations, this paper has informed subsequent work in targeted drug delivery and image-guided interventions. Khettry’s research addresses a critical challenge in nephron-sparing surgery: balancing hemostasis with preservation of healthy tissue. Her polymer-based strategy offers a paradigm shift from mechanical clamping, reducing trauma and improving outcomes. While her publication record is focused, its impact is evident in the growing interest in smart materials for endovascular applications. Khettry’s work exemplifies how interdisciplinary thinking—combining materials science, vascular biology, and surgical technique—can solve practical clinical problems, making her a notable contributor to the future of bloodless surgery.
