Introduction: We evaluated the use of the GreenLight Simulator (GL-SIM) (American Medical Systems, Guelph, ON) in the skill assessment of postgraduate trainees (PGTs) in photoselective vaporization of the prostate (PVP). We also sought to determine whether previous PVP experience or GL-SIM practice improved performance. Methods: PGTs in postgraduate years (PGY-3 to PGY-5) from all 4 Quebec urology training programs were recruited during 2 annual Objective Structured Clinical Examinations (OSCEs). During a 20-minute OSCE station, PGTs were asked to perform 2 exercises: (1) identification of endoscopic landmarks and (2) a PVP of a 30-g normal prostate. Grams vaporized, global scores, and number of correct anatomical landmarks were recorded and correlated with PGY level, practice on the GL-SIM, and previous PVP experience. Results: In total, 25 PGTs were recruited at each OSCE, with 13 PGTs participating in both OSCEs. When comparing scores from the first and second OSCEs, there was a significant improvement in the number of grams vaporized (2.9 vs. 4.3 g; p = 0.003) and global score (100 vs. 165; p = 0.03). There was good correlation between the number of previously performed PVPs and the global score (r = 0.4, p = 0.04). Similarly, PGTs with previous practice on the GL-SIM had significantly higher global score (100.6 vs. 162.6; p = 0.04) and grams vaporized (3.1 vs. 4.1 g; p = 0.04) when compared with those who did not practice on GL-SIM. Furthermore, there were significantly more competent PGTs among those who had previously practiced on the GL-SIM (32.7% vs. 10.2%; p = 0.009). PGY level did not significantly affect grams vaporized or global score (p > 0.05). Conclusion: Performance on the GL-SIM at OSCEs significantly correlated with previous practice on the GL-SIM and previous PVP experience rather than PGY level. Furthermore, there were significantly more competent PGTs among those who had previously practiced on the GL-SIM.
IntroductionBenign prostatic hyperplasia (BPH) is a common progressive disease in aging men. According to the Canadian Urological Association guidelines on BPH, transurethral resection of the prostate (TURP) remains the gold standard of surgical treatment for men with bothersome moderate to severe lower urinary tract symptoms (LUTS).1 Transurethral laser approaches are appropriate and effective treatment alternatives to TURP with lower perioperative complications.
1These laser approaches, among other procedures, include holmium laser enucleation of the prostate (HoLEP) and photoselective vaporization of the prostate (PVP). Although these laser approaches are associated with shorter convalescence and lower perioperative morbidity, they are also associated with a steep learning curve. For example, at least 20 mentored cases are required for the urologist to be comfortable with HoLEP.2 Hence, the Halstedian concept of "see one, do one, teach one" is no longer valid. In addition, reductions in postgraduate trainee (PGT) working hours together with increased public demand for patient s...
