Urethral dilation as treatment for neurogenic bladder

Area of Science:

• Pediatric Urology
• Nephrology
• Pediatric Surgery

Background:

• Neurogenic bladder in children often leads to complications like high detrusor leak point pressure, vesicoureteral reflux, and upper tract dilation.
• Management strategies aim to protect renal function and improve bladder physiology.

Purpose of the Study:

• To evaluate the effectiveness of urethral dilation in managing neurogenic bladder in pediatric patients.
• To assess changes in bladder physiology and clinical outcomes following urethral dilation.

Main Methods:

• Retrospective review of female pediatric patients with neurogenic bladder undergoing urethral dilation (18Fr-36Fr).
• Data collected included urodynamics, infection rates, symptomatology, vesicoureteral reflux, and upper tract dilatation before and after the procedure.

Main Results:

• Urethral dilation was performed a mean of 2 times in 19 children, with a mean follow-up of 34.9 months.
• High detrusor leak point pressure was the primary indication (16 children), leading to improvements in 12 patients.
• Overall improvement was observed in 68% of cases, with significant reductions in vesicoureteral reflux and hydronephrosis, often avoiding further surgery.

Conclusions:

• Urethral dilation is an effective treatment for pediatric neurogenic bladder, particularly for lowering detrusor leak point pressure.
• The procedure demonstrates success in improving upper tract dilatation and vesicoureteral reflux, potentially preventing the need for more invasive surgical interventions.
• Further investigation in prospective studies is warranted to confirm these findings.
