title: Acute urinary retention associated with fractured osteophyte.
abstract: A 24-year-old man presented to our hospital twice with acute urinary retention in March 2002. Myelographic computed tomography demonstrated a posterior osteophyte. The preoperative urodynamic study indicated detrusor overactivity and detrusor sphincter dyssynergia 30 days after the first occurrence of urinary retention. During osteophyte resection and laminoplasty, the osteophyte, which was found to be fractured and to press on the cauda equina, was removed. The postoperative urodynamic study showed that detrusor overactivity remained and detrusor sphincter dyssynergia had disappeared. The patient was regularly followed up as an outpatient, and no dysuria had been noted by January 2003.
