Preventing kidney injury in children with neurogenic bladder dysfunction

Area of Science:

• Pediatric Urology
• Neuro-urology
• Developmental Pediatrics

Background:

• Myelomeningocele is the primary cause of neurogenic bladder dysfunction (NBD) in newborns.
• Untreated NBD, often involving detrusor sphincter dyssynergy (DSD), leads to irreversible urinary tract damage.
• Early intervention is vital to prevent renal damage and long-term bladder issues.

Purpose of the Study:

• To outline the diagnostic and management strategies for NBD in infants with myelomeningocele.
• To emphasize the importance of timely diagnosis and treatment to preserve renal and bladder function.
• To detail therapeutic options for NBD, ranging from conservative measures to surgical interventions.

Main Methods:

• Initial investigations include renal/bladder ultrasound, urine residual measurement, creatinine levels, and urodynamics.
• Voiding cystogram is employed if hydronephrosis or DSD is detected.
• Treatment involves clean intermittent catheterization (CIC), anticholinergics (e.g., oxybutynin), and antibiotics post-myelomeningocele repair.

Main Results:

• CIC with anticholinergics and antibiotics is the primary treatment for high-pressure DSD and reflux.
• Botulinum toxin-A offers an alternative for patients unresponsive or sensitive to anticholinergics.
• Surgery is considered for persistent detrusor hyperactivity or dyssynergy despite maximal conservative management.

Conclusions:

• Effective management of NBD in myelomeningocele aims to prevent urinary tract deterioration and achieve continence.
• A multidisciplinary team approach is essential for comprehensive care.
• Timely and appropriate interventions significantly reduce the risk of future surgeries and long-term complications.
