“…No patient free of bladder neck obstruction demonstrated dyssynergia. Terazosin, an α-adrenergic antagonist, resolved the dyssynergia in six patients [23]. Fifty-three percent of men with BPH were found to be obstructed as defined by Schaefer obstruction grade 3 or greater.…”

“…This gives some insight into the possible timeline of the compensatory phase. However, since obstruction is often nonspecific in its symptomatic presentation it is uncertain how much we can rely on this possible timeline; it seems however that it took less than 4 years in about one‐third of these men to develop obstruction‐induced compensatory increased contractility …”

Studies on bladder dysfunction (BD), more specifically functional‐urodynamic changes in the bladder as a result of bladder outlet obstruction (BOO) have been summarized for this TT. Based on available, but limited evidence from human studies a three‐stage model can be hypothesized to characterize BOO‐induced bladder remodeling: hypertrophy, compensation (increased detrusor contractility during the voiding phase, often in combination with filling phase detrusor overactivity) followed by the phase of decompensation [detrusor underactivity]. The time between the start of compensation and eventual decompensation seems to be determined by age of onset, severity, and type of obstruction and clinical mitigating factors such as vascular and metabolic problems. Understanding the relative contributions of these factors may allow the development of personalized timelines and probabilities for these obstructed patients.

“…Based on the above criteria, however, global clinical urodynamic data in symptomatic patients suggests a DU prevalence of around 10% or more in younger populations, while studies in the elderly tend to show a much higher DU prevalence of up to 40% or more, particularly in elderly men . It has been reported that up to two‐thirds of incontinent nursing home residents show urodynamic evidence of DU .…”

LUTS

Detrusor underactivity (DU) is an important contributor to lower urinary tract symptoms (LUTS). While DU has been defined in the literature in urodynamic terms, current definitions lack specific parameters. In addition, the clinical syndrome associated with and manifesting itself as DU, underactive bladder (UAB), has not been well defined in the literature. In the absence of a precise definition of UAB, it is difficult to appreciate the true nature and burden of this condition. We review the evidence regarding the epidemiology, pathogenesis, diagnosis, and treatment of DU and UAB and discuss the challenges in gathering data in the absence of precise definitions. DU may be idiopathic or caused by ageing, medications, or a number of causes of neurogenic, myogenic, or iatrogenic origin. Treatments are largely palliative due to a lack of curative options, and include watchful waiting, catheterization, medications, and surgical interventions. In light of the evidence available in the literature, we propose that a new symptom-based definition of UAB syndrome should be developed as a first step in furthering more standardized research. Further discussion on this proposed definition to reach expert consensus will enable researchers to gather more robust data, allowing greater insights into DU and UAB diagnosis and treatment.

Lower Urinary Tract Symptoms in Young Men: Videourodynamic Findings and Correlation With Noninvasive Measures

Abstract: Lower urinary tract symptoms in young men have a variety of underlying causes. Videourodynamics is an extremely helpful diagnostic test especially in men with abnormal uroflow and high voiding scores.
