Introduction:

Spinal bifida is a congenital disorder of the spine, which is usually discovered during newborn screening in Taiwan. It usually presents with multiple neurological symptoms including backache, lower extremity muscle weakness, and bowel/bladder dysfunction. The symptoms would progress without surgical intervention because of tethered spinal cord. Here we presented a 25-year-old man with spinal bifida who was diagnosed from lower urinary tract symptoms without other neurological symptoms.

Case report:

This 25-year-old male with no known disease history suffered from hesitancy and incomplete emptying for five years. He also reported to have constipation developed at the same time. No urinary frequency, urgency, nocturia, incontinence, erectile dysfunction, lower extremity muscle weakness or numbness accompanied. Physical examination revealed hair growth at sacral region, and neurological examination showed no motor or sensory defect of the lower extremities. Pressure flow study showed detrusor underactivity (BCI=59) and equivocal bladder outlet obstruction (BOOI=31). Voiding cystography showed non-relaxing sphincter during voiding. Renal sonography excluded hydronephrosis while pelvic MRI revealed spinal cord terminating in a lipoma in sacrum and posterior dysraphism of sacrum, compatible with spinal bifida occulta with tethered cord syndrome. The patient was referred to a pediatric neurosurgeon for surgical release. The operation was done uneventfully, and the lower urinary tract symptoms subsided three months after the surgery. Video urodynamic study would be arranged in April for follow-up.

Conclusion:

Spinal bifida with tethered cord syndrome is usually presenting with multiple neurological symptoms. Patients with bowel and bladder dysfunction only is challenging in diagnosis. Urodynamic study is essential to evaluate the involvement of the lower urinary tract and early referral to neurosurgeon is mandatory to prevent disease progression.
