Spinal dysraphism was categorized into the following 7 subtypes: lipoma-based closed defect, myelomeningocele, meningocele, diastematomyelia, myelocystocele, low-lying conus with tethered cord\/fatty filum, and sacral bony defect. Other factors assessed included patient demographic characteristics, type of spinal dysraphism procedure, reoperation, complication, presence of other neurological problems (e.g., hydrocephalus, Chiari malformation), neurological status, and urological function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Analysis revealed that 114\/1401 patients had coexisting spinal dysraphism. Of these 114, sufficient records including type of dysraphism were available for 54. Spinal dysraphism was most common within cloacal exstrophy (83.3% [45\/54 patients]), followed by cloacal exstrophy variants (9.3% [5\/54]), classic bladder exstrophy (3.7% [2\/54]), and classic bladder exstrophy variants (3.7% [2\/54]). Within spinal dysraphism, lipoma-based closed defects (63.0% [34\/54]) and low-lying conus with tethered cord\/fatty filum (11.1% [6\/54]) were most common. Hydrocephalus and Chiari malformation occurred in 24.1% (13\/54) and 11.1% (6\/54) of patients. All 13 patients with hydrocephalus underwent shunt placement. Among those who underwent neurosurgical intervention, the complication rate for spinal dysraphism was 14.6% (7\/48). Motor function data were available for 41 patients and revealed that motor function declined for 2\/41 (4.8%) patients and improved for 6\/41 (14.6%) after neurosurgery. There was no statistical difference in lower-extremity motor outcome related to timing of neurosurgery and exstrophy closure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>The authors have reported the surgical management and outcomes of patients with exstrophy and coexisting spinal dysraphism (n = 54).

Lipoma-based closed defects (63.0%) and low-lying conus with tethered cord\/fatty filum (11.1%) were the most common, and the rates of hydrocephalus and Chiari malformation were 24.1% and 11.1%, respectively.
