urodynamic study urflowmetry cystometry pressure-flow study


Urodynamic study is a valuable diagnostic tool for evaluation of functional state of the lower urinary tract. The references from English PubMed and Mediline data and our own experiences are used. The paper presents technique of urodynamic studies. The most common technical problems are discussed and the way of their avoiding. Fist part includes: history, frequency and volume chart, uroflowmetry, cystometry and pressure-flow.
