ABSTRACT
Objective To verify the efficiency of a new laparoscopic urethrovesical anastomosis training model by comparing it with the chicken skin model. Methods Chicken posterior trunks and porcine colons were used to construct the training model. The posterior trunk of a chicken was used to simulate a human pelvis, and a 3-mm cloacal stump was used to simulate a human urethral stump. A 15-cm segment of porcine colon with a 1-cm orifice was used to simulate a human bladder or neobladder. An imitation urethrovesical anastomosis was performed with laparoscopic instruments in a laparoscopic training box. Forty trainees with no laparoscopic experience were randomized into 2 groups.The trainees in group A (n=20) practiced using this new model for 8 h, while those in group B (n=20) practiced using the chicken skin model for 8 h. The trainees' skills were assessed using the porcine model before and after training. Results Compared with the chicken skin model, this new training model more accurately resembled the structure and characteristic of human pelvis, urethral stump, and bladder (neobladder). After the training sessions, both groups improved in anastomosis time [GroupA (64±11)min vs. (123±20)min, P<0.05; Group B (77±12)min vs. (121±17)min, P<0.05] and quality (Group A 8.8± 1.0 vs. 3.8 ± 1.2, P<0. 05 ; Group B 7.7 ± 0.9 vs.3. 7± 1.1, P<0. 05). Compared with trainees in group B, trainees in group A required less time and achieved a higher quality score (P<0.05). Conclusions This new training model can help urologic surgeons to reduce learning curve of this technique and improve their suturing skills. It is an effective,convenient training model for laparoscopic urethrovesical anastomosis.
