Abstract:
Objective:To investigate the feasibility, effectiveness and safety of ultrasound-guided transperineal prostate biopsy (TPB) with coaxial needle technique, and to improve the pain perception of TPB patients by reducing the number of direct perineal needling.Methods:A total of 200 patients who underwent ultrasound-guided TPB at the first clinical college of Three Gorges University & Yichang Central People′s Hospital from January 2019 to December 2020 were randomly divided into coaxial needle group (coaxial needle positioning puncture, n=100) and traditional group (traditional puncture frame guided repeated transperineal puncture, n=100). Visual analog scale (VAS) was used to evaluate the pain of patients during puncture. The number of samples, time-consuming of puncture, cancer detection rate, VAS pain score and complications between the two groups were compared. Results:The success rate of puncture in the coaxial needle group and the traditional group was 100%, and there was no significant difference in the cancer detection rate between the two groups (48% vs 40%, P>0.05). The average number of samples in the coaxial needle group was larger than that in the traditional group, the average puncture time in the coaxial needle group was less than that in the traditional group, and the average intraoperative VAS score of the coaxial needle group was lower than that of the traditional group, the differences were statistically significant[(14.8±1.8) vs (12.1±1.1), (12.9±1.3)min vs (16.5±1.9)min, (2.6±1.2) vs (4.4±1.4); all P<0.001]. The complication rate of the coaxial needle group was lower than that of the traditional group, the difference was statistically significant (18% vs 39%, P<0.001), the incidences of perineal hematoma and perineal pain in the coaxial needle group were lower than that in the traditional group (1% vs 8%, 8% vs 19%; all P<0.05). Conclusions:Coaxial needle technology for ultrasound-guided TPB can ensure the number of samples and accurate sampling in different areas, significantly reduce the number of direct perineal puncture, improve the pain in the process of puncture, reduce the incidence of postoperative perineal pain, with shorter operation time and fewer complications, which is worthy of clinical promotion.
