Computer technology has made it possible significantly to improve the technique and interpretation of the micturitional urethral pressure profile (MUPP). Thirty-nine patients with lower urinary tract symptoms have been investigated by this technique and the results compared with those of standard pressure/flow studies. A good correlation was found between the two methods of diagnosing outflow obstruction, but micturitional urethral pressure profiles offered practical advantages in patients who were elderly, immobile or who had severe involuntary voiding, and diagnostic advantages in patients with absent or poor detrusor contractility and those with equivocal pressure/flow studies.
A new method of performing urethral pressure profiles and fluid bridge tests using computer technology is described, demonstrating the advantages over standard equipment. The fluid bridge test has been used to detect bladder neck incompetence in the male both before and after bladder neck surgery and has been adapted to investigate sphincter weakness at the distal urethral sphincter. This study suggests that the fluid bridge test is useful in the urodynamic evaluation of retrograde ejaculation, post-prostatectomy incontinence and vesico-urethral neuropathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
