Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.
