Objective |
To describe the development and implementation of a process for creating accurate Pediatric genitourinary 3D modeling and printing with multiphase postcontrast imaging for surgical planning.
Materials and Methods |
Additive manufacturing and 3D model present opportunities to support clinical planning, this manuscript's specific process and considerations for creating pediatric genitourinary 3D modeling to support urology. The process for creating the 3D models and prints covers 3 key aspects from image acquisition, imaging review and selection, and segmentation and modification (as needed). Each step is outlined with the key roles and procedures.
Results |
The described case had digital and printed models prepared with references to the optimized imaging sequence for 3D modeling of Pediatric genitourinary. Case shared include complex genitourinary reconstruction and Kideny with Wilms tumors.
Conclusion |
The processes described have become a standard of practice for complex kidney tumors and exstrophy planning. The team continues to work on ever-changing improvements to make the best possible models to support clinical and surgical planning.

| Key Results: Optimized imaging sequence for 3D modeling of Pediatric genitourinary including 3D isotropic image with 0.4 mm spatial resolution and 3D T1 weighted gradient echo acquisition sequence with fat saturation (TR/TE: 4.0/1.5 msec) with an in-plane resolution of 0.6 mm and a through plane slice thickness of 3 mm to achieve a temporal resolution of 8 to 9 seconds per dynamic scan during gadolinium excretion. Presents defined workflow and roles for the creation of Pediatric genitourinary from acquisition to surgical feedback. Case shared include complex genitourinary reconstruction and Kideny with Wilms tumors. |
