Difficulty arises when comparing completely different methods of diagnosing bladder outlet obstruction. A comprehensive review of the literature on the different methods used to diagnose bladder outlet obstruction by noninvasive means was performed with a view to allow such a comparison. MATERIALS AND METHODS: A MEDLINE search was done of the published literature covering until the end of 2004 on noninvasive methods, including single measure and combinations of measures, to diagnose bladder outlet obstruction. A direct comparison of all of the different methods was made using the sensitivity, specificity, likelihood ratio, and pretest and posttest probability of diagnosing bladder outlet obstruction for each test. For many techniques these values were calculated from the data presented in the article. RESULTS: A multitude of methods has been applied to diagnose bladder outlet obstruction. Broadly the methods were divided into nonurodynamic and noninvasive urodynamic methods. Nonurodynamic methods were considered in part 1 of the review. Part 2 considered noninvasive urodynamic techniques, such as uroflowmetry, the penile cuff, the condom method and Doppler urodynamics. A combination of single measures was also considered and the relative merits of these approaches were discussed. CONCLUSIONS: A combination of noninvasive urodynamics and ultrasound derived measures provide promising methods of diagnosing bladder outlet obstruction. However, pressure flow studies still remain the gold standard for assessing bladder outlet obstruction. Noninvasive methods of diagnosing bladder outlet obstruction in men. Part 2: Noninvasive urodynamics and combination of measures. M Belal P Abrams doi:10.1016/S0022-5347(06)00570-2 J Urol, Vol. 176, No. 1.

With the progressive aging of the population, it is important to understand common micturitional disorders that may occur in this population. Most urinary problems in the elderly are multifactorial in origin, demanding a comprehensive assessment of the lower urinary tract organs, functional impairments, and concurrent medical diseases. Urodynamics is a highly valuable tool in the investigation of elderly patients with lower urinary tract symptoms. Urodynamic tests are not always necessary, being indicated after excluding potentially reversible conditions outside the urinary tract that may be causing or contributing to the symptoms. Although urodynamic tests may reveal common diagnoses such as bladder outlet obstruction and stress urinary incontinence in the elderly population, findings such as detrusor overactivity and impaired detrusor contractility are common and have important prognostic and therapeutic implications. The purpose of this article is to describe common urologic problems in the elderly and review the indications for and clinical aspects of urodynamic studies in these conditions.

These questions are addressed in this article. There are disparities in the assessment of lower urinary tract dysfunction between the accuracy of symptomatic assessment and the underlying pathophysiology. This is particularly evident with voiding symptoms, in contrast to storage symptoms, and has fuelled the debates that have resulted in the abandonment of the term 'prostatism' in favor of 'lower urinary tract symptoms', whereas the term 'overactive bladder syndrome' has been embraced as a storage symptom complex. Clearly, voiding disorders principally affect men, whilst storage disorders are more common in women. Much has been written and spoken about regarding the use of symptomatic assessment versus urodynamics in the assessment of lower urinary tract symptoms in men, whilst there has been a clearer consensus on the potential usefulness of urodynamics in the assessment of storage disorders, and so this article focuses principally on the latter topic.
