A 53-year-old man encountered a rare side effect after the implantation of a spinal cord stimulator (SCS), which initially provided significant pain relief. Despite the device’s success in reducing chronic low back and lower extremity pain, he developed persistent penile pain that standard treatments could not alleviate, ultimately leading to the device’s removal.
Patient’s Journey with Spinal Cord Stimulator
The patient received a Boston Scientific spinal cord stimulator, positioning the leads at the T8 level to address chronic pain stemming from post-laminectomy syndrome. Following a successful trial that yielded 70% pain reduction and improved functionality, the permanent implant achieved approximately 40% pain relief over two months.
Unprecedented Complication and Resolution
After the initial relief period, the stimulator’s effectiveness declined, and the patient began experiencing ongoing low back pain coupled with new penile pain characterized by allodynia. Attempts to reprogram the device failed to provide relief, and pharmacological interventions, including Gabapentin, Pregabalin, THC, and opioids, proved ineffective. Comprehensive dermatological and urological evaluations revealed no underlying issues, prompting the decision to explant the SCS. Post-explantation, the patient’s penile pain resolved immediately, confirming the device’s role in the unexpected complication.
Key inferences from this case include:
- Spinal cord stimulation may cause rare and unforeseen side effects beyond commonly reported complications.
- Penile allodynia could be a direct result of SCS implantation, necessitating awareness among clinicians.
- Standard reprogramming and pharmacologic treatments might not address all device-related complications, making explantation a necessary option.
This case highlights the importance of vigilant monitoring for unusual side effects in patients receiving spinal cord stimulators. Medical professionals should consider device-related causes when patients present with atypical pain symptoms, ensuring timely intervention to maintain patient quality of life. Further research into the diverse impacts of SCS can aid in preventing and managing rare complications, enhancing the overall effectiveness of chronic pain management strategies.
