[Evaluation of 2 inanimate models to improve percutaneous fluoroscopy-guided renal access time].

Background: Training devices for percutaneous renal access are expensive, have hazardous biological materials, or radiation. Two devices were designed that eliminate some or all of these characteristics (ManiPERC and iPERC).

Objective: To compare the improvement in access time to the posterior lower calix with 2 inanimate models in a group of Urology residents.
