Abstract: 3D Urinary Tract Models for Urologic Research Applications
Authors: Nicholas J. Gregory, Stephen H. Arce Ph.D., Victoria Y. Bird M.D.
Keywords: 3D model, Procedural Simulation,
Paper Abstract Submission Category: Education, Simulation & Virtual Reality
Introduction:
The yearly cost of urologic based procedures are over five billion dollars, with nearly 3.3 million Americans seeking treatment for kidney stone disease and 25 million patients requiring urinary catheter placement. Our team has created a 3D urinary tract model using computer-aided design with accurate dimensions of the urinary tract capable of being used for training of urethral and ureteral procedures.
Methods:
An initial 3D NIH template was used to create a anatomically dimensionally correct model of the urinary tract exclusively for urologic based procedures. The Autodesk Meshmixer software was used in order to create a hollow, accurately dimensioned urinary tract model. The model was initially made solid using a 6 mm offset, followed up by a 5.5 mm offset hollowing. In addition, a 21 French, 20 cm long male urethra with a 60 degree bend 4 cm prior to the bladder junction was made using OnShape, a separate computer-aided design software. Several Materials were explored with the aim of making a flexible and transparent model of the urinary tract.
Results:
A modified version of the National Institutes of Health (NIH) 3D printable urinary tract system was the most effective model to use while maintaining the most desirable characteristics of creating a dimensionally accurate 3D model for simulations. The 3D urinary tract model was printed with an approximately 350 cc bladder volumetric capacity (which can expand with pressure), ureters with varying circumferences of 15 to 21 French and a linear length of approximately 20 cm, a renal pelvis that opens to a circumference of 30 French, and three major calyces with multiple minor calyces attached making up the kidney portion of the urinary tract model.
The modified NIH 3D printable model was printed using a tango (Exo-1,7,7-trimethylbicyclo[2.2.1]hept-2-yl acrylate developed by stratasys), silicone rubber-like material by an Objet260 Connex2 3D printer. This material was chosen because of it elastic, flexible, durable, and translucent qualities.
Conclusion:
We propose that after multiple trials in developing a dimensionally accurate 3D urinary tract model that a 3D print of a modified NIH 3D printable model using a tango (rubber-like) material is best for uses in training for urologic procedures. In addition, the model allows for further research in medical devices used in urology and can serve as an educational tool for the public.
Summary: This Author explored extensively different materials to build the ideal three-dimensional (3D) model and methods to design and construct an efficient 3D urinary tract model to test cystoscopy and ureteroscopy procedures. Several materials and methods were surveyed and compared for best efficacy of creating a 3D urinary tract model.References: E. N. Marieb, et. al., Human Anatomy & Physiology
