Abstract
The Valsalva leak-point pressure has become an important urodynamic test in the evaluation of incontinent women. A review of the history of the test, its methodology, and variables that can influence its performance is presented. Correlation with clinical findings, reproducibility and comparison with other urodynamic tests are discussed. Although the test is still evolving and several major variables have been recognized as affecting its results, it remains sound and reliable. It has excellent correlation with the clinical severity of incontinence and a high degree of inter- and intraexaminer reproducibility.
