- W1483458054 abstract "Three-dimensional printing is on the cusp of revolutionizing medical practice, including urology. This technology allows a 2-D image to be printed in 3-D, so the physical image comes to life. The applications are endless, and each day that I talk to a new physician about this technology, their excitement and abundance of ideas are palpable. Our group at Tulane University, New Orleans, Louisiana, USA, has begun to use this printing technology to take 2-D cross-sectional imaging, and create a physical 3-D model that is unique and individualized to each patient.1 The individualized, perfect replica of the patient's organ of interest can then be used as an educational tool for patients, medical students, residents or surgeons. To visualize a 2-D image in 3-D is a technique that takes time and skill to develop, thus patients and young trainees often struggle with understanding and interpreting this. For complex lesions, even experienced surgeons might have different interpretations, which can influence surgical subtleties. To date, much of our group's work has focused primarily on renal lesions, but there is likely great value for a variety of other urological applications – from individualized penile prostheses to focal ablation treatment of prostate lesions. Our emerging work has begun to center on manipulating the physical properties of the materials used to create the models, so that it more closely replicates soft tissue. To this end, there has been an evolution of our technique.2 We have begun to show that by using this technique, patient-specific, individualized, surgical simulation is possible, allowing a surgeon a “dry run” to resect a patient-specific renal lesion before actually touching the patient. We will be presenting videos showing this technique and early outcomes at the American Urological Association meeting in New Orleans.3, 4 If 3-D printing of a patient-specific soft tissue organ before organ-sparing surgery is to become the norm, several barriers need to be overcome: the cost to create the physical 3-D models needs to be to be relatively low, the time to create the models needs to be relatively brief, the accessibility needs to be high and we need to show that such models significantly influence patient outcomes. Several of these “barriers” are easily achieved; the cost can be very low (well less than $100), but is dependent on the desired physical properties of the models. Multicolor, translucent models with materials that can be cut through simulating actual surgery are considerably more expensive, and printers with these properties can cost hundreds of thousands of dollars. Models can also cost thousands. As the technology evolves, these costs are likely to be dramatically reduced. Also, the printing process itself is done in hours, but still requires a knowledgeable technician, as it is not fully automated. Finally, demonstrating an impact on patient outcomes is challenging and costly, but we are currently accumulating data to this end. None declared." @default.
