Intermittent catheterization rather than urinary diversion in children with meningomyelocele
Insights
Self-catheterization helps girls with meningomyelocele achieve urinary continence. This method avoids urinary diversion in most cases and can improve bladder function for successful anti-reflux surgery.
Area of Science:
- Pediatric Urology
- Neurology
- Nephrology
Background:
- Neuromuscular defects, such as meningomyelocele, often lead to urinary incontinence in children.
- Traditional management includes urinary diversion, which can be invasive and have long-term complications.
Purpose of the Study:
- To evaluate the efficacy of intermittent intraurethral catheterization for achieving urinary continence in girls with meningomyelocele.
- To assess the impact of catheterization on bladder function and upper urinary tract health.
Main Methods:
- A cohort of 15 girls over 4 years old with meningomyelocele and urinary incontinence were managed with self- or parent-administered intraurethral catheterization.
- Bladder function, upper tract status, and continence rates were monitored.
Main Results:
- 14 out of 15 girls achieved adequate urinary continence.
- Indwelling catheterization facilitated bladder wall smoothing, enabling successful anti-reflux surgery in one case.
- No upper tract deterioration was observed, and sterile urine was maintained in 50% of cases with a 3-hour catheterization schedule.
Conclusions:
- Intermittent intraurethral catheterization is a viable alternative to urinary diversion for managing urinary incontinence in girls with meningomyelocele.
- Successful implementation requires a collaborative team approach involving parents, child, nurses, and physicians.
- This approach supports potential future interventions like artificial urinary sphincters and avoids early, irreversible conduit diversion.
Abstract:
Fifteen girls more than 4 years old and with neuromuscular defects of meningomyelocele are maintaining adequate urinary continence through the use of intraurethral catheterization done by themselves or their parents. Urinary diversion has been necessary in only 1 child. The indwelling catheter has allowed heavily trabeculated bladders to become smooth enough for an antirflux operation to be successful, although the period of followup is only 2 years. Upper tract deterioration has not been observed and urine has been maintained sterile without the help of medication 50 per cent of the time when catheterizations have been done on a routine 3-hour schedule. For this method to be sucessful and replace conduit deversion, parents, child, nurse and physician must be a well-knit team. With the hope that a reliable artificial urinary sphincter will eventually provide contience for some children, one is further justified in pursuing urinary continence by use of the catheter, instead of resorting early to permanent conduit conversion.
