A fictional 41-year-old with worsening back pain develops new urinary retention, bilateral leg symptoms and altered perineal sensation.
Frame the danger first.
- New bladder or bowel dysfunction with back pain, saddle sensory change or bilateral neurological symptoms is a spinal emergency until excluded.
- Document lower-limb power, sensation, reflexes and perineal/sphincter symptoms sensitively and clearly.
- Urinary retention alone has multiple causes; neurological context determines urgency.
Act, escalate, reassess.
- Assess ABCDE, relieve retention safely where appropriate and activate the local cauda-equina or spinal emergency pathway.
- Obtain urgent senior spinal/neurosurgical advice and arrange emergency MRI according to local access arrangements.
- Record symptom onset and neurological progression precisely.
- Avoid discharge or routine outpatient imaging where cauda-equina red flags remain plausible.
Red flags that change pace.
- Saddle anaesthesia, new bladder/bowel dysfunction or sexual dysfunction
- Bilateral sciatica, progressive motor weakness or severe sensory change
- Rapidly progressive pain or neurological deficit
What makes care less safe.
- Attributing retention to analgesia or benign back pain without neurological review
- Inadequate documentation of perineal symptoms
- Delaying specialist discussion until MRI is available
Say the concern plainly.
Possible cauda equina syndrome: onset/progression [time], bladder/bowel symptoms [details], saddle symptoms [present/absent], leg neurology [summary], MRI and spinal-team plan [status].
