Valsalva leak point pressure: how to chose the best method.
Urinary continence is ensured as long as the urethral closure pressure remains greater than the intravesical pressure, in the presence of adequate support to the bladder and the proximal urethra. In order to select the appropriate surgical treatment, a correct diagnosis must be made; recently urodynamic evaluation has assumed a central role. In particular, the introduction of a new urodynamic parameter, the Valsalva Leak Point Pressure (VLPP), has provided new impetus to research in this area, even if different technical approaches have limited universal acceptance. The aim of the work is to describe the reasons why the authors have been led to prefer double measurement, both at partial filling and at maximum cystometric capacity, considering that this does not involve any additional economic burden. The authors underline the promising potential of the method, once standardized, in the urodynamic evaluation of urinary incontinence.
