Does selective dorsal rhizotomy improve bladder function in children with cerebral palsy?

Area of Science:

• Neurology
• Pediatrics
• Urology

Background:

• Cerebral palsy (CP) often presents with neurological impairments affecting bladder control.
• Urinary symptoms like urgency, frequency, and incontinence are common in children with spastic CP.
• Selective Dorsal Rhizotomy (SDR) is a surgical procedure primarily used to reduce spasticity.

Purpose of the Study:

• To evaluate the effectiveness of Selective Dorsal Rhizotomy (SDR) in managing urinary symptoms in children with cerebral palsy.
• To assess the impact of SDR on urodynamic parameters related to bladder function.

Main Methods:

• SDR was performed on 56 children diagnosed with spastic cerebral palsy.
• Surgical intervention involved dividing specific nerve roots (L1/2 to S1/2) in the cauda equina.
• Urinary symptoms and urodynamic study (UDS) results were analyzed pre- and post-operatively.

Main Results:

• Significant improvements were observed in urinary urgency, frequency, and incontinence post-SDR.
• 54.5% of children with urgency/frequency and 75% of incontinent children became asymptomatic or continent.
• Bladder capacity at first incontinence significantly increased from 70 ml to 130 ml (p=0.016).

Conclusions:

• Selective Dorsal Rhizotomy is an effective treatment for improving bladder control in children with spastic cerebral palsy.
• SDR positively impacts key urodynamic parameters, specifically bladder capacity.
• The procedure offers a significant improvement in quality of life by reducing debilitating urinary symptoms.
