Introduction: Development of clinical skills through simulation models is essential for a professional performance with minimal error on real patients.

Objective: Define if there is a significant difference in the performance of the installation of a urinary catheter between simulation models and real patients from students of the forth year of the medical degree in Universidad Autónoma de Yucatán.

Method: We performed a pilot study of educational intervention, we applied a program to achieve the process "Urinary catheter installation" (one hour theory and fifteen hours of practice per pupil) to a group of 11 students. Afterwards it was apply a checklist to measure the performance achieved in a simulation model (MS) patients and on real patients (PR). Statistical analysis was performed with Student's t-test.

Results: Twenty parameters were evaluated and found significant differences (p<0.02) in the following steps: Before insertion; gather the material MS 11/11 (100%) and PR 2/11 (18%), verify the operation of urinary catheter MS 9/11 (82%) and PR 2/9 (22%). During insertion; Separate lips MS 7/11/64%) and PR 1/11 (9%), keeping the urinary catheter coiled MS 10/11 (91%) and PR 0/11 (0%), evaluate the characteristics of urine MS 4/11 (36%) and PR 0/11 (0%). After insertion; Connect drainage MS 10/11 (91%) and PR 1/11 (9%) and record the proceedings MS 7/11 (64%) and PR 2/11 (18%).

Conclusions: Students achieve better skills on urinary catheter installation after simulation model training.
