Complete multichannel urodynamic assessment

The complete multichannel urodynamic assessment is the most exhaustive functional exploration of the lower urinary tract. It combines several complementary tests in a single session: uroflowmetry, filling cystometry, pressure-flow study and urethral profilometry, with simultaneous recording on several pressure channels. Multichannel recording makes it possible to measure bladder pressure, abdominal (rectal) pressure, detrusor pressure (calculated), urethral pressure and urinary flow at the same time. This comprehensive approach provides a complete picture of bladder and sphincter function and allows the different parameters to be correlated with one another. This assessment is indispensable in complex clinical situations where a single test is not enough to establish a precise diagnosis. It is particularly useful in conditions combining several dysfunctions (for example, obstruction and bladder instability, or mixed incontinence) and in cases where an initial simplified assessment was inconclusive. The complete multichannel urodynamic assessment is the gold standard of functional urological exploration, and its results directly guide the treatment strategy: medical treatment, pelvic floor rehabilitation, neuromodulation or surgery.
