Urological Aspects of Spinal Dysraphism.

Abstract

Micturition requires complex interplay involving bladder, peripheral neural network, spinal cord, and brain. Spinal dysraphism presents variety of neural lesions that may affect this interplay leading to neurogenic bladder. However, the diagnosis of neurogenic bladder in those with spinal dysraphism is often difficult and contrasted to other types of neurogenic bladder caused by complete neural lesions such as spinal cord injury or brain tumor. Typically, neurogenic bladder caused by spinal dysraphism shows lower motor neuron lesion and partial neural injury. However, upper motor signs can be seen with the occurrence of tethered cord syndrome and developmental immaturity of bladder control often complicated by fecal impaction. Thus, the diagnosis of tethered cord syndrome should be made cautiously. Several invasive and noninvasive diagnostic modalities could be applied for accurate diagnosis, preventing renal damage and controlling urinary incontinence. However, it should be borne in mind that no single study is definitive for accurate diagnosis, so it requires careful scrutiny in interpretation. The follow-up scheme of these patients should be determined to detect urological deterioration due to the development of tethered cord syndrome. Since the development of tethered cord syndrome shows diverse nature implicating urological and orthopedic issues, multidisciplinary collaboration is essential for comprehensive care.
