Abstract: Objective To introduce a training model for laparoscopic dismembered pyeloplasty. Methods The model of
ureteropelvic junction obstruction was simulated using pig kidney and chicken crop. With the model placed in a training box,
8 residents without laparoscopic experience but with basic technical training performed 10 rounds of anastomosis according to
the standard operation procedures. For each resident, the operating time and quality of the operation were recorded and
assessed. Results All the 8 residents successfully completed the training. The operating time decreased from 72.70±8.26 min in
the first training session to 54.50±7.69 min in the last training session, and the anastomosis error score decreased from 5.60±1.35
to 2.50 ± 1.58 min, showing significant differences between the recordings (P<0.05). Conclusion This simple training model
allows effective simulation of the surgical procedures of laparoscopic pyeloplasty and is suitable for training surgeons without
laparoscopic experiences.
