[Prediction of continence in patients with neurogenic bladder who will be treated with bladder augmentation].
Twenty four patient with neurogenic bladder undergoing vesical enlargement were pre-operatively evaluated to determine the need to perform also an anti-incontinence technique. None of them had such a technique performed, so as to control whether our prediction was correct. Each patient had one or more video-urodynamic studies performed to evaluate adjustment and the likely vesical hyperreflexia, critical incontinence pressure, and the presence of leaks with cough and cervicourethral morphology at different filling times. Critical incontinence pressure and presence of contrast leaks with cough, the latter demanded with moderate intravesical pressures, have been the parameters which better predicted the likely incontinence, with reliability over 90%. With regard to myelodysplastic bladders, the study shows the relevance of the detrusor as a cause of incontinence and sustains the practice of implementing only the cervical cuff without the remaining components when the artificial sphincter is chosen as the anti-incontinence technique, when the likely cause, whether sphincter or detrusor, is unclear at the time of considering vesical enlargement.
