Abstract

Hypothesis / aims of study
We report a new percutaneous navigation technology that can be used for sacral neuromodulation in patients with sacral deficiency or sacral defect. The operative technique is simple and can increase the effective rate of sacral neuromodulation
Study design, materials and methods
preoperative localization of the sacrum CT and sacral nerve MRI scan were performed on the subjects. The CT and MRI data were fused and three-dimensional formed. On the 3D model, the percutaneous needle path was designed according to the sacral nerve, and the puncture navigation template was designed according to the positioning patch. The optimal side nerve implant electrode was selected according to the puncture navigation template in the operation.
Results
of the seven patients receiving 3D printing, three males and four females, age 26 + 13.51 years, two sacral absence and five sacral defect, bilateral sacral 2 nerve to sacral 4 nerve partial deletion, three cases of right nerve and four left nerve in phase I test, and two cases implanted sacral 2 nerve, four cases implanted sacral 3 nerve, one case implanted sacral nerve. In the final test, the symptoms of urination were improved in four patients, and the II permanent electrodes were implanted. oen patient were not tested, one patient improved less than 50%, no II permanent electrodes were implanted, and one patient was still effective in the I phase test. The total effective rate was 66.67%.
Interpretation of results
3D printing technology can make sacral nerve defects and sacral nerve defects benefit from sacral neuromodulation, improve urination symptoms and improve quality of life.
Concluding message
3D printing technology can make sacral nerve defects and sacral nerve defects benefit from sacral neuromodulation, improve urination symptoms and improve quality of life. This technology has also broken the way of puncturing the sacral neuromodulation, which is of great significance for the improvement of the operation.
