Spinal cord injury in children: long-term urodynamic and urological outcomes

Urological complications in adults with spinal cord injuries (SCIs) are well documented. We sought to determine the effect of SCI on the developing bladder and kidneys in the child. We retrospectively reviewed cases of SCI with 1-year minimum followup. We identified 42 children with an average age a...

Description
Summary:	Urological complications in adults with spinal cord injuries (SCIs) are well documented. We sought to determine the effect of SCI on the developing bladder and kidneys in the child. We retrospectively reviewed cases of SCI with 1-year minimum followup. We identified 42 children with an average age at injury of 5.3 years (range 1 day to 14 years). Mean followup was 5.5 years (range 1 to 15.5). Videourodynamics, sonograms, infection, medications and continence were reviewed. Safe bladder capacity was defined as the pressure specific volume at 40 cm water or less. Patients were divided into 3 groups based on level of injury-cervical (10), thoracic (26) and lumbar (6). Bladder management included clean intermittent catheterization in 40 of 42 patients and antispasmodics in 37. No patient had reflux, hydronephrosis or renal scarring. In the cervical group safe bladder capacity was less than the expected capacity in 80% of patients but all patients undergoing multiple urodynamics had increasing capacity with time. In the thoracic group 58% of patients had a safe bladder capacity less than expected and 76% of those undergoing multiple urodynamics had increasing capacity. In the lumbar group 50% of patients had a safe bladder capacity less than expected and 67% of those undergoing multiple urodynamics had increasing capacity. To our knowledge this is the largest and longest urological study of young children with SCI. Early clean intermittent catheterization and use of anticholinergics appear to prevent upper tract deterioration, improve continence and decrease infections. Serial urodynamics confirm increasing safe capacity with growth in most children. Close followup is necessary as bladder characteristics may change with time.
