Purpose: Anorectal malformation (ARM) is often accompanied by spinal
cord abnormality or neurovesical dysfunction. However, only a few studies
have comparatively assessed spinal cord abnormality and urodynamic
data. We evaluated the effect of spinal cord abnormalities on perioperative
neurovesical dysfunction and investigated the necessity of urodynamic
study in patients with ARM.
Materials and Methods: From 1993 to 2007, 219 patients with ARM
were newly diagnosed at our institution; A retrospective study was conducted
on 20 patients who underwent preoperative and postoperative urodynamic
Results: Of 20 patients, 10 had abnormal spinal cords. Fourteen (70%)
presented abnormal urodynamic findings (detrusor overactivity, dysfunctional
voiding, detrusor sphincter dyssynergia, combined overactivity and
dyssynergia, or detrusor acontractility). Preoperative urodynamic abnormalities
were reported in 6 of 10 patients with abnormal spinal cords and
8 of 10 patients with normal spinal cords. New postoperative urodynamic
abnormalities were reported in 2 patients in the abnormal spinal cord
group, while 2 preoperative cases were resolved. In the normal spinal
cord group, 2 preoperative cases were converted to other forms of urodynamic
Conclusions: We advocate routine preoperative and follow-up urodynamic
assessment of all patients with anorectal malformation, regardless
of spinal cord abnormality.
