Application of three-dimensional printed guiding device for electrode implantation in sacral neuromodulation in children / 现代泌尿外科杂志

ABSTRACT

【Objective】 To investigate the application value of three-dimensional printed guiding device in sacral neuromodulation in children. 【Methods】 A total of 17 patients admitted during Jan.2017 and Nov.2022 were divided into two groups control group (n=8), using traditional method to locate sacral foramen for puncture; three-dimensional printed guiding device group (n=5), using three-dimensional printing technology to make individual guiding device for puncture. The clinical indexes of the two groups were evaluated, including puncture time, puncture numbers, intraoperative X-ray exposure times, postoperative evaluation time and second-stage conversion rate. The evaluation indexes of postoperative complications were wound bleeding, wound infection, wound rupture, electrode fracture, displacement or prolapse. 【Results】 In the control group, 1 case was diagnosed as bladder-bowel dysfunction, the remaining 7 were neurogenic bladder; in the three-dimensional printed guiding device group, all 9 cases were diagnosed as neurogenic bladder. The puncture time was shorter in the three-dimensional printed guiding device group than in the control group [85(70-90) min vs.138(133-208) min], the puncture numbers were fewer [15(12-20) vs.22(18-26)], and the X-ray exposure times were fewer [12(12-17) vs.19(16-23)] (all P<0.05). The initial stimulation voltage, postoperative evaluation time and second-stage conversion rate were not statistically significant. 【Conclusion】 Compared with the traditional method, the use of three-dimensional printed guiding device can reduce the puncture numbers and shorten the puncture time in the process of sacral neuromodulation in children.
