Introduction. Transurethral catheterization (TUC) is a common hospital procedure. According to the literature, junior doctors contribute to the majority of TUC-related injuries. Our aim is to evaluate the immediate and long-term impact of a short procedure-centric TUC workshop on junior doctor’s confidence, procedural knowledge, and ability to identify potential complications of catheterization. Materials and Methods. Intern doctors were invited to attend a one-hour workshop on TUC. A questionnaire was completed before and after the workshop. Three months later, the questionnaire was readministered to assess the workshop’s long-term impact. The questionnaire consisted of three domains. A: experience, training, and confidence levels (using 5-point Likert scales), B: procedural knowledge (the highest possible score was 10 points), and C: identification of TUC-related complications (the highest possible score was 3 points). Results. 81 interns participated and reported a confidence level of 3.03 ± 1.05 in performing a straightforward TUC. Preworkshop domain B and domain C were 3.92 ± 1.63 and 1.75 ± 0.69 points, respectively. After the workshop, reported confidence levels improved to 3.71 + 1.02 (
p
<
0.05
). Likewise, the scores in domains B and C increased significantly to 8.85 ± 1.40 (
p
<
0.005
) and 2.65 ± 0.6 (
p
<
0.005
), respectively. Three months later, the same parameters were evaluated, and confidence levels were higher than those of the preworkshop levels at 3.83 ± 0.77 (
p
<
0.05
). The average domain B score was 7.85 ± 1.88 (
p
<
0.005
), and domain C score was 2.69 ± 0.53 (
p
<
0.005
). All scores reported after three months were significantly better than the preworkshop levels (
p
<
0.005
), but there were no statistically significant differences when compared to the immediate postworkshop scores (
p
>
0.05
). Conclusion. Short peer-led TUC workshops positively impact intern doctors’ confidence levels, procedural knowledge, and identifying complications.
