Engineering a Microsurgical Training Tool for Vasectomy Reversals

We describe the development of an elastomer-molded vas model as a microsurgical training tool, particularly for vasectomy reversals. This microsurgical training tool is formed by molding polydimethylsiloxane into a vas deferens shape with a patent lumen through the use of a 3D printed mold and simple monofilament wires. The expanded use of our vas model as a microsurgical training tool will allow urologists in training to improve and develop their microsurgical skills outside of patient caseloads and without the need for extensive cadaveric or animal model practice.
