Pyeloplasty Training Model for Laparoscopic Procedures

The pyeloplasty model allows for medical students or surgeons to be trained on many different types of laparoscopic procedures. The inner and outer surfaces of the model have contrasting colors to allow for easier discrimination between the surfaces while performing the anastomosis. Along with the model, a holder is available to secure the renal pelvis and ureter when using a laparoscopic training box. There are also black light sensitive marking on the model that allow for analysis of twisting at the anastomosis.

Pyeloplasty Model Reconstructed from Anatomical Structures

The interactive pyeloplasty model mimics human anatomical structures because the model is reconstructed using anatomical structures as mold templates and, using a database of tissue behavior algorithms, the organs, vessels and tissue layers produced simulate real human structures. This provides a much more realistic teaching tool than a traditional anatomical manikin. The pyeloplasty model has the look and feel of the entire structure, as it would be within the human body. The lifelike simulation allows medical students to interact and perform a variety of laparoscopic procedures on a near exact copy of the pyeloplasty.

The pyeloplasty model was constructed using synthetic materials that were benchmarked against mechanical properties of human tissue using the University of Minnesota CREST Lab’s Human Tissue Properties Database. Synthetic materials give the model the touch and feel of the renal pelvis, ureteropelvic junction, and ureter as it would be within the human body.


  • Accurate representation of pyeloplasty anatomy
  • Allows for training of laparoscopic procedures
  • Use of synthetic materials gives lifelike touch and feel to model
  • Contrasting colors of model layers allow for easy discrimination during training
