Abstract:

Objective　To constructa training model for laparoscopic partial nephrectomy (LPN)using isolated porcine kidney, as well as to evaluateits efficacy in LPN training.　Methods　Adipose and other tissues outer to the renal fascia were removed from the isolated porcine kidney. Two concentric circles with different diameters of 28 mm and 32 mm were placed on the surface of the porcine kidney, respectively. The trainees, including 6 experts, 6 intermediates and 8 novices, were asked to perform a LPN to evaluate the validity of the training model. The operative time,the suture time, the damage of two concentric circles, and the length of the wounds after suturewere recorded.  Likert scale was used by 6 experts to evaluate the appearance, the anatomical structure, the operation texture, and the overall realistic simulation of the model.　Results　In Likert scale, quality assessment of the model for anatomical structure was 5.00±0.00, for appearance was 4.33±0.52, for operation texture was 4.33±0.52, and for overall realistic simulation was 4.67±0.52. There were significant differences among the three groups in operative time, suture time, damage of two concentric circles, and length of the wounds after suture (P<0.05).　Conclusion　The training model was suitable for advanced training of LPN with its advantages in simplicity, economy and high fidelity of operation simulation.
