Spinal Cord Magnetic Resonance Imaging for Investigation of Nonneurogenic Lower Urinary Tract Dysfunction—Can the Yield be Improved?
چکیده انگلیسی

PurposeMagnetic resonance imaging has been used to detect occult neuropathy in patients with nonneurogenic lower urinary tract dysfunction. There is substantial controversy surrounding the role of this test for lower urinary tract dysfunction. We identified factors associated with positive magnetic resonance imaging to improve patient selection.Materials and MethodsA case-control study was done in all pediatric patients referred to our radiology department for spinal magnetic resonance imaging primarily because of lower urinary tract symptoms between 1995 and 2004. Patients with known neurological disorders or anomalies associated with neurogenic bladder (overt spinal dysraphism, imperforate anus, etc) were excluded. A total of 80 patients with a median age of 6.5 years (range 4 to 17) were identified, of whom 47 (59%) were female. Bivariate analysis was used to evaluate the association of certain variables with positive magnetic resonance imaging findings, including patient age, gender, type of urinary symptoms, fecal soiling, abnormal neuro-orthopedic examination, lumbar cutaneous findings, resistance to medical management and urodynamic findings.ResultsMagnetic resonance imaging revealed spinal abnormalities in 6 cases (7.5%), including intradural arachnoid cyst in 1, sacral dysgenesis in 3, syrinx/hydromyelia in 1 and tethered cord in 1. An abnormal lumbar cutaneous finding was the only variable associated with positive magnetic resonance imaging (Fisher’s exact test p = 0.002).ConclusionsSpinal magnetic resonance imaging has a low impact in the management of lower urinary tract dysfunction. With proper patient selection the pretest probability of positive magnetic resonance imaging may be increased and, therefore, many unnecessary studies may be avoided. Abnormal cutaneous findings are associated with abnormal magnetic resonance imaging.
