Introduction Three-dimensional (3-D) printing systems allow for the creation of surgical models mimicking real tissue. We developed a kidney graft and pelvic cavity replica as a patient-specific 3-D model using a 3-D printing system with simultaneous jetting of different materials and subsequently evaluated the usefulness of surgical simulation and navigation of living kidney transplantation. Methods After generating a stereolithographic file of the organ surface based on multidetector computed tomographic data, we created a 3-D organ model using an inkjet 3-D printer and manufactured a pelvic cavity replica using patient-specific data. Results The patients' individual 3-D printed models were used to plan and guide the surgical procedures for laparoscopic donor nephrectomy and recipient transplantation surgery. The 3-D organ replicas obtained using transparent materials allowed for the creation of models that showed the visceral organs, blood vessels, and other details, thereby overcoming the limitations of conventional image-guided navigation. Our pelvic replicas can be made according to each patient's specific anatomical data, thus representing personalized surgical procedures. This level of detail of the anatomy enables the surgeons and trainees to virtually treat various pelvic conditions before they perform the surgical procedure. The use of these replicas may also reduce the length of the operation and provide better anatomical reference tools for tailor-made simulation and navigation of kidney transplantation surgery, consequently helping to improve training for the operating room staff, students, and trainees. Conclusions We believe that our sophisticated personalized donor graft and pelvic replications obtained using a 3-D printing system are advantageous for kidney transplantation surgery.
