Abstract

Classically, it was understood detrusor contractility was affected in bladder areflexia but not in hyperreflexia. We aim to demonstrate that there is some detrusor contractility affectation in bladder hyperreflexias, although it may seem paradoxical at first sight. Neuro-urologic study was performed in a series of 68 consecutive patients with bladder hyperreflexia (neurogenic detrusor hyperactivity), referred to the unit of functional urology for urodynamic evaluation. All patients underwent clinical history, post void residual determination, cystomanometry, voiding pressure-flow test, videourodynamics and selective EMG of the periurethral sphincter. Detrusor contractile potency was measured with W 80-20. Terminology follows the ICS standard. Data processing was performed using the statistical software SPSS 12.0. This series includes 14 males (58.8%) and 28 females (41.2%), of all ages (adults more frequent). 88.2% of the cases had acquired neurological diseases (trauma 30.9%; medical 33.8%; degenerative 35.3%), and 11.8% congenital neurological diseases (myelodysplasia). Most frequent type of neurological lesion was detrusor-sphincter dyssynergia: 59 cases (79.4%); 22 patients (32.4%) had undergone previous treatment of their ...Continue Reading
