Summary
A fractured posterior osteophyte compressing the cauda equina caused acute urinary retention and detrusor sphincter dyssynergia. Surgical removal resolved the detrusor sphincter dyssynergia, improving bladder function.
Area of Science:
- Neurology
- Urology
- Spinal Surgery
Background:
- Acute urinary retention can be caused by spinal cord compression.
- Posterior osteophytes are bony growths that can impinge on neural structures.
- Detrusor overactivity and detrusor sphincter dyssynergia are common urodynamic findings in urinary retention.
Observation:
- A 24-year-old male presented with recurrent AUR.
- Imaging revealed a posterior osteophyte impinging on the cauda equina.
- Preoperative urodynamics showed detrusor overactivity and DSD.
Findings:
- Surgical decompression via osteophyte resection and laminoplasty was performed.
- The fractured osteophyte was removed.
- Postoperative urodynamics confirmed resolution of DSD, with persistent detrusor overactivity.
Implications:
- Spinal osteophytes should be considered in the differential diagnosis of AUR, especially in younger patients.
- Surgical intervention can effectively treat DSD caused by spinal compression.
- Further management may be needed for persistent detrusor overactivity post-decompression.
