"Latex glove" laparoscopic pyeloplasty model: a novel method for simulated training.

PURPOSE: To present a 'latex glove' laparoscopic pyeloplasty (LPP) training model and determine its construct validity for its effective use in resident training.

MATERIALS AND

METHODS

The 'latex glove' model was used to perform LPP by five operators with variable level of experience, ranging from an experienced (> 20 independent LPPs) to minimal operative experience (year 5 medical student). The palm of the glove was considered the renal pelvis with finger of the glove as the proximal ureter. A knot at the junction of the two was considered as ureteropelvic junction obstruction. A basic lap trainer was used to simulate the LPP. Operation time was noted in minutes and quality of continuous suturing was determined for each operator, using a previously described nonvalidated scoring system by a blinded reviewer.

RESULTS

The operation time varied from 47 to 160 minutes for the most to the least experienced operator, and the difference was statistically significant (P = .043), while the quality of suturing score ranged from 1 to 6 for the most to the least experienced operator, respectively (P = .038). The operation time and quality of suturing were negatively correlated with the level of experience (-0.962 and -0.987, respectively), which were statistically significant (P = .009 and P = .002, respectively).

CONCLUSION

This novel training model has proven its validity, as a cost-effective and readily available option for LPP training.
