Computational Modeling and Simulation in Endoscopic Urological Surgery

The goal of this project is to develop computer-based methods for planning and simulating surgical procedures on the human kidney, specifically the removal of kidney stones and tumors using minimally invasive (endoscopic) techniques. The researchers are generating virtual three-dimensional geometric models of patient-specific kidney anatomy from computed tomography scans and using resources at the SDVL for model creation. The next step will be to convert this model, which is in so-called STL format, to a more information-rich format, called DCEL, that is amenable to efficient algorithm manipulation. The researchers will also investigate methods for modeling the surgical device (ureteroscope).

These prototypes will be used for pre-surgical simulation and training and will facilitate the selection of the appropriate type of scope and the corresponding motion trajectories. The researchers are using resources at the SDVL for model creation.
