Concept: Lower urinary tract symptoms

Storage lower urinary tract symptoms (LUTS) including overactive bladder (OAB) and urinary incontinence (UI) affect millions of people worldwide, significantly impacting quality of life. Plant based medicines have been documented both empirically and in emerging scientific research to have varying benefits in reducing bladder symptoms. We assessed the efficacy of Urox®, a proprietary combination of phytomedicine extracts including, Cratevox™ (Crataeva nurvala) stem bark, Equisetem arvense stem and Lindera aggregata root, in reducing symptoms of OAB and UI.

To report 3-year outcomes of a prospective, multi-center, randomized, blinded control trial after treatment with convective radiofrequency (RF) water vapor thermal therapy for moderate to severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

This report evaluates clinical experience with the Rezūm system after US Food and Drug Administration clearance in consecutive cases accrued by multiple community urologists for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Treatment techniques for transurethral convective radiofrequency water-vapor thermal therapy and outcomes with up to 12 months' follow-up are presented.

Benign prostatic hyperplasia (BPH) and its associated lower urinary tract symptoms (LUTS), including nocturia, are extremely common among middle- and older-aged American men. While studies of physical activity (PA) and prevalent BPH-related outcomes suggest that PA may protect against the development of this common condition, only a few studies have examined the relation between PA and incident BPH-related outcomes and LUTS with mixed findings. Additionally, although nocturia is the most commonly reported and most bothersome LUTS in men with or without evidence of BPH, few studies have examined the association of PA and nocturia independent of BPH. The purpose of this analysis was to examine the association of PA with BPH-related outcomes and nocturia in the PLCO Trial.

Chronic prostatic inflammation is implicated in the pathogenesis of benign prostatic hyperplasia (BPH)-associated lower urinary tract symptoms (LUTS). Previous studies evaluated the degree of chronic prostatic inflammation based on histological scores, which may contain subjective factors. We previously demonstrated that the number of high endothelial venule (HEV)-like vessels correlates positively with the magnitude of inflammation in chronic inflammatory gastrointestinal diseases. Here, we evaluated the degree of BPH-associated chronic prostate inflammation based on appearance of HEV-like vessels and determined whether the extent of inflammation correlated with LUTS severity, as evaluated by a urodynamic study.

Evidence to substantiate recommendations for restriction of caffeinated or acidic beverages as self-management for lower urinary tract symptoms (LUTS) is limited. We examined longitudinal and acute associations between beverage intake and LUTS in the Boston Area Community Health (BACH) cohort (n = 4,145) between 2002 and 2010. Multivariable models tested associations between baseline intakes and progression of LUTS at 5-year follow-up, between follow-up intakes and International Prostate Symptom Scores at follow-up, and between 5-year intake changes and LUTS progression. Greater coffee or total caffeine intake at baseline increased the odds of LUTS progression in men (coffee: >2 cups/day vs. none, odds ratio = 2.09, 95% confidence interval: 1.29, 3.40, P-trend = 0.01; caffeine: P-trend < 0.001), particularly storage symptoms. Women who increased coffee intake by at least 2 servings/day during follow-up (compared with categories of decreased or unchanged intakes) had 64% higher odds of progression of urgency (P = 0.003). Women with recently increased soda intake, particularly caffeinated diet soda, had higher symptom scores, urgency, and LUTS progression. Citrus juice intake was associated with 50% lower odds of LUTS progression in men (P = 0.02). Findings support recommendations to limit caffeinated beverage intake for LUTS, and in men, they suggest benefits of citrus juice consumption. Further clinical research is warranted, particularly of the precise role of sodas containing artificial sweeteners in bladder sensations and urological function.

Lower urinary tract symptoms (LUTS) comprise storage symptoms, voiding symptoms and post-voiding symptoms. Prevalence and severity of LUTS increase with age and the progressive increase in the aged population group has emphasised the importance to our society of appropriate and effective management of male LUTS. Identification of causal mechanisms is needed to optimise treatment and uroflowmetry is the simplest non-invasive test of voiding function. Invasive urodynamics can evaluate storage function and voiding function; however, there is currently insufficient evidence to support urodynamics becoming part of routine practice in the clinical evaluation of male LUTS.

Lower urinary tract symptoms (LUTS) and sexual dysfunction (SDys) are common problems that affect quality of life (QOL) in elderly men. In addition to prescribed drugs, many over-the-counter medications including supplements are used to treat QOL diseases. Phosphodiesterase inhibitors are reported to be effective for both LUTS and SDys by increasing nitric oxide levels. French maritime pine bark extract Pycnogenol(®), which is a potent nitric oxide donor, is reported to be effective for SDys. However, no reports have been published on whether it ameliorates LUTS.
