Abstract:
PURPOSE: Frontal lobe disease may cause disorders of storage as well as voiding. The aim of this study was to elucidate the reliability of the urodynamic difference of an exact anatomical lesion within the frontal lobe. MATERIALS AND METHODS: 29 patients who had only frontal lobe lesions, without any other cause for neurogenic bladder, were evaluated by an urodynamic study. The frontal lobe lesions were classified into anterior, medial, posterior and lateral aspects, and the patients evaluated by an urodynamic study and MRI. RESULTS: From the urodynamic study on the 29 patients, 27 showed neurogenic detrusor overactivity (93.1%), with the other 2 (6.9%) showing normal findings. On electromyographic findings (EMG), uninhibited relaxation of sphincter was seen in 20 cases (69.0%), and the other 9 were normal (31.0%). It appeared that medial aspects within the frontal lobe lesions were particularly important in uninhibited relaxation of the sphincter. In this study, an urodynamic study showed variable findings, and the EMG especially showed different results depending on the location of the lesion within the frontal lobe. CONCLUSIONS: Variable findings from the urodynamic study were found in patients within the frontal lobe lesions. Thus, the correct urodynamic study for effective treatments should be analyzed.
