Negative History for Neurogenic Bladder

1. No Neurological Diagnosis or Disorder

Patient denies any known neurological diagnosis, history of stroke, spinal cord injury, multiple sclerosis, Parkinson's disease, spina bifida, or peripheral neuropathy.

2. No Neurological Symptoms

• No limb weakness, paralysis, or paresis
• No sensory loss or numbness (especially in saddle/perineal area)
• No history of spasticity or abnormal reflexes
• No cognitive impairment or dementia
• No gait disturbance or coordination problems
• No history of seizures

3. No Bowel or Sexual Dysfunction Suggesting Shared Neurological Involvement

• No constipation, fecal incontinence, or altered bowel habit of neurological origin
• No erectile dysfunction or ejaculatory dysfunction (men)
• No loss of genital sensation or orgasmic dysfunction (women)
• No altered anal sphincter tone

4. No History of Spinal or Pelvic Surgery/Trauma

• No history of lumbar or thoracic spinal surgery
• No history of pelvic surgery (radical prostatectomy, radical hysterectomy, abdominoperineal resection) that could have damaged pelvic autonomic nerves
• No pelvic fracture or perineal trauma

5. No Relevant Medications

• No anticholinergics, antipsychotics, or antidepressants (can cause urinary retention)
• No alpha-blockers or calcium channel blockers affecting bladder outlet

6. No Congenital Urological Abnormalities (Pediatric Context)

• No history of spina bifida, sacral agenesis, or anorectal malformations
• No history of posterior urethral valves or other structural anomalies
• No prior bladder augmentation

7. Urodynamic/Symptom Profile Does Not Suggest Neurogenic Pattern

Summary Statement (Clerking Template)

"Patient denies any history of neurological disease including stroke, Parkinson's disease, multiple sclerosis, spinal cord injury, spina bifida, or diabetic neuropathy. No history of spinal or pelvic surgery. No associated bowel dysfunction, sexual dysfunction, saddle anaesthesia, or limb weakness. No known congenital urological abnormalities. Cognitive function, gait, and coordination are intact."

Negative History — Neurogenic Bladder Secondary to Sacral Agenesis

1. No Maternal History of Diabetes

• Mother had no pre-gestational or gestational diabetes mellitus
• No maternal insulin use during the first trimester
• (Note: 16% or more of sacral agenesis cases have an insulin-dependent diabetic mother — this being absent narrows the etiology)

2. No Family History (Currarino Syndrome)

• No family history of sacral agenesis
• No known Currarino triad (sacral dysgenesis + anorectal malformation + presacral mass/anterior meningocele)
• No HLXB9 mutation identified in family members

3. No Anorectal Malformation

• No imperforate anus or anorectal malformation
• No history of colostomy or anorectal surgery
• Normal bowel habit (no neurogenic bowel)
• No fecal incontinence or chronic constipation

4. No Associated Syndromic Features

• No features of VACTERL (vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, limb abnormalities)
• No features of caudal regression syndrome (sirenomelia, lower limb fusion)
• No lower limb orthopedic deformity (no claw toes, hammer toes, or high-arched feet — though these may be subtle clues if present)

5. No Lower Extremity Neurological Deficit

• No lower limb weakness or paralysis
• No sensory loss in the lower extremities
• Normal gait (this is a hallmark that leads to delayed diagnosis)

6. No Upper Urinary Tract Deterioration (at time of presentation)

• No hydronephrosis
• No vesicoureteral reflux (VUR) — (VUR can occur in up to 65% of sacral agenesis patients)
• Normal renal function (creatinine/GFR)
• No history of recurrent UTIs causing upper tract damage
• No renal scarring on imaging

7. No Complications of Neurogenic Bladder (Yet)

• No history of renal calculi
• No bladder stones
• No prior bladder surgery or augmentation
• No prior clean intermittent catheterization (CIC)
• No history of autonomic dysreflexia (less relevant at sacral level but worth noting)

8. No Symptoms Suggesting a Higher Neurological Lesion

• No urgency or urge incontinence (storage symptoms that suggest an UMN/overactive component)
• (Note: urodynamics in sacral agenesis can show either UMN (35%) or LMN (40%) or no denervation (20–25%) — the clinical history alone does not reliably predict this)

9. No Other Cause of Neurogenic Bladder

• No spina bifida (myelomeningocele)
• No tethered cord syndrome
• No diastematomyelia
• No presacral mass

Summary Clerking Statement

"Patient is a known case of sacral agenesis presenting with [urinary incontinence/dribbling/recurrent UTIs]. Mother had no history of diabetes mellitus. No family history of sacral agenesis or Currarino syndrome. No anorectal malformation. No lower limb weakness or sensory deficit; gait is normal. No features of VACTERL or caudal regression syndrome. No evidence of hydronephrosis, VUR, or renal impairment. No prior urological intervention. No bowel incontinence."
