title: Noninvasive urodynamics: a study of male voiding dysfunction.
abstract: A group of 26 patients was tested for isovolumetric pressure and optimal flow rate by means of the cuff-uroflow (CUF) technique. The same patients were also examined in the clinic, and a diagnosis was recorded. The two processes were performed independently in a statistically double-blind manner. Standard statistical comparisons were made, and it was shown that there exists substantial correlation between the results of clinical examination and the cuff-uroflow procedure. It was also shown that the CUF technique converged more rapidly to a correct diagnosis than standard clinical procedures. Surgical treatment and watchful waiting were examined and it was shown, as expected, that surgical treatment resulted in substantial improvement in most cases, but that watchful waiting generated no statistically significant change.
