To independently design a lithotomy position pelvic fixation device for use in patients undergoing transperineal prostate biopsy under local anesthesia, aiming to improve patient cooperation during the lithotomy position surgery and provide an effective tool to reduce adverse reactions associated with prostate biopsies under local anesthesia.

Using convenience sampling, 120 patients undergoing transperineal prostate biopsy under local anesthesia at our hospital's Urology center from July to September 2024 were selected as research subjects. They were divided into control and observation groups of 60 cases each based on their admission order. The control group was positioned in the lithotomy position with leg strap fixation, while the observation group used the independently designed lithotomy position pelvic fixation device. Comparisons were made between the two groups regarding positional changes, biopsy surgery time, incidence of gross hematuria postoperatively, and surgeon satisfaction.

The operation time in the observation group [(9.45±1.31) min] was significantly shorter than that in the control group [(13.37±1.49) min]. Patients using the lithotomy position pelvic fixation device show fewer positional changes during the transperineal prostate biopsy compared to the control group. The incidence of gross hematuria was lower in the observation group compared to the control group. Surgeon satisfaction was higher in the observation group compared to the control group, with all differences being statistically significant (P<0.05).

The application of the lithotomy position pelvic fixation device effectively reduces positional changes caused by fear and pain in patients undergoing transperineal prostate biopsy under local anesthesia, thereby significantly shortening the surgical time. This device demonstrates significant advantages in improving patient cooperation, reducing adverse reactions,and enhancing surgeon satisfaction, making it worthy of further promotion and application in clinical practice.
