PURPOSE
The urological outcome after prenatal myelomeningocele (MMC) repair is still controversial; how-
ever, recent data indicate a possible positive effect on postnatal bladder function. We aim to present
an update on the urologic outcome during early childhood after prenatal MMC repair.
MATERIAL AND METHODS
All patients operated prenatally for MMC at our institution are followed prospectively. Assessment
includes urinary ultrasound, VCUG and urodynamic study, need for clean intermittent catheteriza-
tion (CIC) and anticholinergics, and the occurrence of urinary tract infections (UTI).
RESULTS
Of the 40 patients who underwent prenatal MMC closure since 2010, one patient died after birth
due to respiratory failure. 39 patients were included in this study. Postnatal urodynamics revealed
neurogenic bladder dysfunction (NBD) in 46%. The percentage of NBD increased during the first
6 months to 76% and remaining stable during further follow-up at 65%. After 6 months none of
the patients with normal bladder function spontaneously developed bladder dysfunction; however
5 patients lost normal bladder function after removal of intradural dermoids. Vesico-ureteral reflux
was found in 6 (15%) patients. Three NBD-patients (11%) had at least one febrile UTI, patients with
normal bladder function were infect-free. CIC and anticholinergic therapy was initiated in all NBD
patients. Four patients additionally received intravesical botox injections, one patient developed
upper tract deterioration and underwent vesicostomy.
CONCLUSIONS
Our data suggest that prenatal MMC repair yields less bladder dysfunction than expected after
postnatal repair. However, further evolution of bladder function in these patients throughout child-
hood is indispensable.
