Continuous two-channel water cystometry: Description of an alternative test for evaluating incontinent women

A continuous two-channel cystometric method (CTCHM) for monitoring bladder function in women suffering from urinary incontinence is described. The purpose of this technique is to provide a cheap minimal evaluation for patients who cannot afford an electronic examination. Through the CTCHM it was possible to diagnose detrusor instability in 11.1% of 108 patients. This method has proved to be useful in a developing country, where an electronic urodynamic evaluation is expensive or often is not available.
