we report a new surgical method for the treatment of male lower urinary tract symptoms. The operation is minimally invasive through percutaneous intervention, and the patient is conscious during the whole operation.

The location of the sacral CT and the MRI scan of sacral nerve and pudendal nerve were performed before surgery. The CT and MRI data were fused and 3D formed. On the 3D model, the percutaneous needle path was designed according to the shape of the nerve, and the puncture navigation template was designed according to the positioning patch. During the operation, the optimal lateral nerve implantation electrode was selected according to the puncture navigation template.According to sacral 3 nerve low frequency, sacral 3 nerve high frequency, pudendal nerve high frequency, pudendal nerve low frequency, bilateral nerve low frequency and pudendal nerve low frequency stimulation nerve.

at the end of the patient, the pudendal nerve electrodes were implanted on the left side, and the sacral 3 nerve electrodes were implanted on the right side. Compared with the sacral 3 nerve stimulation and bilateral nerve stimulation, the vaginal stimulation of the pudendal nerve could reduce the frequency of urination and urgency (19 + 3.21vs32.78 + 1.56vs24.14 + 3.13). At the same time, the low frequency stimulation of the pudendal nerve was better than the high frequency stimulation of the pudendal nerve, the low frequency of the sacral 3 nerve and the high frequency of the sacral 3 nerve. (92.93 + 9.00vs54). .22 + 30.81vs22.86 + 11.00vs33.05 + 14.70)%, especially the low frequency stimulation of pudendal nerve is the best.

pudendal nerve as a branch of sacral 3 nerve can directly treat male lower urinary tract symptoms.

pudendal nerve as a branch of sacral 3 nerve can directly treat male lower urinary tract symptoms. However, the location of the pudendal nerve and electrode displacement need to be solved.
