Once the needle is properly positioned along the sacrococcygeal disc line, 1 mL of radiopaque contrast is injected. The needle placement is confirmed in the lateral fluoroscopic view as a comma-shaped spread in the retroperitoneal space. Radiofrequency interventions on the ganglion impar are performed using a radiofrequency generator. A 22G radiofrequency needle (0.7×98.6 mm) with a 10 mm exposed active tip is used. Before performing the ablation, tissue impedance and motor and sensory responses (motor and sensory stimulation) are checked. The expected tissue impedance is \<500 ohms. Sensory paresthesia at \<1 V and 50 Hz is observed around the sacrococcygeal region. Pulsed RFA is applied at 42 °C for 4 minutes after stimulation.
