Abstract:
Objective:To investigate the efficacy of 3D-printed navigation guided pudendal lead implantation on nervous regula-tion of lower urinary tract symptoms(LUTS)in male patients.Methods:Twenty-eight male patients who underwent perineal nervous regulation treatment for LUTS in Gongli Hospital of Pudong New Area from October 2021 to October 2023 were randomly divided into observation group and control group.The technology assisted with 3D-printed navigation to regulate the genital nerves was used in ob-servation group.And the patients in control group were treated with regulation of the genital nerves by routine puncture.Operation time of puncture,number of surgical punctures,and stimulator debugging time compared between the two groups.The improvement of post-operative symptoms and surgical complications of patients in the observation group were recorded as well.Result:A total of 12 male LUTS patients were included in the observation group,with an average age of 36.5±6.5 years,including 7 cases of frequent micturi-tion,3 cases of perineal pain,and 2 cases of dysuria.Four patients showed no significant improvement in symptoms,including two pa-tients with pain and two cases of frequent micturition who did not undergo secondary surgery.While the other eight patients showed sig-nificant improvement in symptoms.The average time for successful puncture in control group was(21.13±4.53)minutes,which was longer than that of the 3D-printed navigation group([10.32±3.42]min)significantly(P＜0.05).The average number of punctures in the ordinary puncture group was 5.62±1.43,which was significantly higher than that in the 3 D-printed navigation group(1.5±0.56).There was no statistically significant difference in the average time for stimulator debugging between the two groups of patients.The conversion rate of the 3D-printed navigation group in the second phase was 66.7％,which was higher than that(37.5％)significantly(P＜0.05).Conclusion:3D printing navigation of pudendal nerve electrode wire implantation can improve the accuracy of electrode implantation and the conversion rate to a certain extent,which has the advantages of reducing the difficulty of surgery.
