Abstract: Objective To evaluate the teaching effect of stepped training model in transrectal ultrasound-guided transperineal prostate biopsy(PB). Methods Forty doctor trainees in the department of urology of Peking Union Medical College Hospital were randomly divided into two groups: experimental group and control group, with 20 trainees in each group. The experimental group received the stepped teaching model; The control group received the traditional training model. Both groups participated in the training of transperineal PB guided by transrectal ultrasound. One week later, all the members were tested for manipulation and surveyed by the teaching satisfaction questionnaires. Results Eighteen trainees in the experimental group could successfully perform transperineal PB independently, while only twelve trainees in the control group could operate independently, and the completion time of the experimental group was less than that of the control group(P＜0.01). The questionnaire survey showed that the teaching satisfaction score of trainees in the experimental group was higher than that in the control group(P＜0.01). Conclusions The stepped teaching model of transperineal PB guided by transrectal ultrasound is effective in clinical training.
