Abstract：Urolithiasis is a common and frequently-occurring disease in urinary system. Spiral CT is one of the commonly used methods in clinical examination. The anatomy of the urinary system is complex with a wide range of lesions. Two-dimensional inspection has some limitations. Three-dimensional reconstruction technology based on plain CT scan images multidimensional reconstruction, maximum density shadow projection, surface and volume reproduction technology, surface reconstruction and virtual endoscopy after processing, can rebuild thin layer, more solid and visually present the anatomical structure of urinary system, from multiple perspectives show calculus, shape, size, the lesion site and its three-dimensional space position relations, and with the aid of three-dimensional reconstruction technology provides the digital simulation of virtual surgery may, for the diagnosis and treatment of urinary calculi has important practical significance. In this paper, three-dimensional reconstruction and simulation surgery were summarized and analyzed, and its shortcomings were summarized to provide a reference for clinical personalized accurate surgery.
