Self-retaining catheters for congenital neuropathic bladder: a continuing evaluation
Summary
Continuous Foley catheter management for spina bifida (SB) patients shows stable renal function long-term. However, prolonged use (over 4 years) is linked to increased renal scarring and reduced bladder emptying in children with SB.
Area of Science:
- Pediatric Urology
- Nephrology
- Neurology
Background:
- Spina bifida often results in neuropathic bladder dysfunction.
- Long-term management strategies for neuropathic bladders in children are crucial for preserving renal function.
Purpose of the Study:
- To evaluate the long-term effects of continuous Foley catheterization on renal function and bladder management in children with spina bifida.
Main Methods:
- A cohort of 60 children with spina bifida were managed with continuous Foley catheterization for up to 14 years.
- Renal function was assessed using Technetium renogram and renal scans before and after the intervention.
Main Results:
- No significant overall deterioration in renal function was observed in 66 kidneys over the study period.
- Patients with continuous catheterization exceeding 4 years showed significantly less intermittent emptying (p < 0.001) and more renal scarring (p < 0.01).
- Complications requiring intervention occurred in 28% of patients, primarily males.
Conclusions:
- Continuous Foley catheterization can maintain stable renal function in spina bifida patients long-term.
- Prolonged use of continuous catheterization (over 4 years) is associated with adverse effects on bladder emptying and increased renal scarring.
