The potential of 3D printing in urological research and patient care.

3D printing is an evolving technology that enables the creation of unique organic and inorganic structures with high precision. In urology, the technology has demonstrated potential uses in both patient and clinician education as well as in clinical practice. The four major techniques used for 3D printing are inkjet printing, extrusion printing, laser sintering, and stereolithography. Each of these techniques can be applied to the production of models for education and surgical planning, prosthetic construction, and tissue bioengineering. Bioengineering is potentially the most important application of 3D printing, as the ability to produce functional organic constructs might, in the future, enable urologists to replicate and replace abnormal tissues with neo-organs, improving patient survival and quality of life.
