Abstract

Most patients with Complex Regional Pain Syndrome (CRPS) have single limb involvement. Involvement of the upper versus lower limbs have been reported fairly equally. However, CRPS type 1 has been reported in other body regions, such as the head, proximal limb and genitalia. A 34-year-old male patient presented with deep pain and marked allodynia on his perineum, including the scrotum and penis, following urethroplasty 9 months previously. He had been taking the oral medication prescribed by the urologist for 8 months, but his symptoms were not relieved. Under the diagnosis of CRPS type 1 caused by the operation, nerve blocks, including caudal and inferior mesenteric plexus blocks, were performed. However, the patient's symptoms were not satisfactory relieved. Therefore, ganglion impar block was performed with 99.9% alcohol, after which his pain markedly decreased. At the short term follow up, 3 months after the block, he was satisfied with the treatment.
