Intermittent catheterization rather than urinary diversion in children with meningomyelocele.

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.
