Reconstructive urologists are constantly facing diverse and complex pathologies that require structural and functional restoration of urinary organs. There is always a demand for a biocompatible material to repair or substitute the urinary tract instead of using patient’s autologous tissues with its associated morbidity. Biomimetic approaches are tissue-engineering tactics aiming to tailor the material physical and biological properties to behave physiologically similar to the urinary system. This review highlights the different strategies to mimic urinary tissues including modifications in structure, surface chemistry, and cellular response of a range of biological and synthetic materials. The article also outlines the measures to minimize infectious complications, which might lead to graft failure. Relevant experimental and preclinical studies are discussed, as well as promising biomimetic approaches such as three-dimensional bioprinting.

Clinical Applications of 3D Printing

Three-dimensional (3D) printing refers to a number of manufacturing technologies that create physical models from digital information. Radiology is poised to advance the application of 3D printing in health care because our specialty has an established history of acquiring and managing the digital information needed to create such models. The 3D Printing Task Force of the Radiology Research Alliance presents a review of the clinical applications of this burgeoning technology, with a focus on the opportunities for radiology. Topics include uses for treatment planning, medical education, and procedural simulation, as well as patient education. Challenges for creating custom implantable devices including financial and regulatory processes for clinical application are reviewed. Precedent procedures that may translate to this new technology are discussed. The task force identifies research opportunities needed to document the value of 3D printing as it relates to patient care.

“…For those reasons, 3D printed anatomical models have already been used in training of surgeons [18][19][20][21][22][23][24][25][26][27][28][29]. As the use of 3D printers in hospital will become increasingly integrated to medical imaging, introducing this technology early in undergraduate training could help students familiarize themselves with the conversion of preoperative imaging data to CAD files and the printing of personalized surgical models [30].…”

Access to cadaveric specimens, which is dependent on donation and heavy equipment, is still a limiting factor in the study of anatomy. As there are many spatially challenging structures throughout the human body for which physical support is beneficial, new strategies are always needed to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. In this report, the author reveals the use of rapid prototyping technology to create an innovative and anatomically accurate teaching tool to engage students and help them build threedimensional (3D) mental maps of the human heart. The model consists of polylactic acid (PLA) thermoplastic deposited layer by layer on a platform in a pattern that corresponds to a digital Standard Tessellation Language (.stl) file. Printing a hollow human heart with a 1:1 ratio was rapid (<5 hrs) and affordable (approximatively US$5 per model). Given access to the appropriate printable digital files, students could print their own model and could subsequently paint them appropriately to give them an anatomically correct representation. This studentcentered activity is an extension of the current anatomy coloring textbooks, with the benefit of building an accurate 3D representation of the human body.
