Abstract

Pudendal neuralgia is characterized by severe sharp pain along the innervation area of pudendal nerve, which may be worsened when sitting position. Successful pudendal nerve block is crucial to the diagnosis of pudendal neuralgia. Although fluoroscopy-guided pudendal nerve blocks have traditionally been performed, recently ultrasound-guided pudendal nerve blocks were reported. For the long term effect of nerve block, pulsed radiofrequency was performed under fluoroscopic guidance in some reports. We report our successful experiences of three cases using ultrasound-guided pulsed radiofrequency.
