Low urethral pressure profile--clinical implications.

The clinical impact of urethral pressure profilometry (UPP) has been a main urological topic over the past three decades. Exaggerated expectations and differing techniques with incongruent results caused a controversial appearance. However, since the UPP is the only method to measure directly aspects of the urethral closure function, all types of sphincteric urinary incontinence represent indications for this measurement. Based on long-term experience this paper aims to discuss the various complexes regarding the urethral pressure profilometry. The significance of the urethral closure function for urinary continence and the urodynamic relevance of active and passive pressure transmission are described. In addition, clinical implications in terms of therapeutic strategies to treat urinary stress incontinence with regards to a low urethral pressure profile are presented.
