Urodynamic evaluation of tethered cord syndrome including tight filum terminale: prolonged follow-up observation after intraspinal operation.

From pre- and postoperative urodynamic examinations of congenital neurogenic bladder caused by tethered cord syndrome including tight filum terminale, the results of intraspinal surgery on tethered cord syndrome are reported herein. As a result, urodynamic and electrophysiologic examinations are considered as excellent methods, which are safe and give objective findings, for diagnosis and prolonged observation of not only tethered cord syndrome but also congenital neurogenic bladder.
