[Clinical observations of the effects on the lower limb function after lumbar or sacral nerve root transferring to reconstruct urination function].

Objective: To observe the effects on the lower limbs function after lumbar or sacral nerve root transferring to reconstruct urination function.

Methods: Nine patients with bladder dysfunction and normal lower limb function after spinal cord injury were treated with anastomosis the S2 or S3 nerve root with the normal lumbar or sacral nerve root to reconstruct a new bladder artificial reflex arc. Then the alterations on the sensation and motor function of the lower limb after the surgery were observed.

Results: Myodynamia of the legs decreased slightly, and the decreasing about half grade of the myodynamia in the plantar flexion of the ankles were detected in 4 of 9 patients with S1 transferring. And the myodynamia recovered 3 months postoperatively. No obvious decreasing of the myodynamia appeared in the other cases.

Conclusion: No obvious effects on the motor function can be found after the single lumbar or sacral nerve root transferring to reconstruct urination function.
