Purpose: There is a widely held perception that lower urinary tract symptoms may be exacerbated by cold weather. In this study, we examine the effect of seasonal variation in ambient temperatures on frequency-volume chart derivatives, symptom severity scores and uroflowmetry parameters in men with lower urinary tract symptom. Methods: Between January 2000 and April 2004, men presenting with lower urinary tract symptom were prospectively recruited and assessed in Edinburgh, UK (55 degrees 52'N) with maritime temperate climates (Koppen classification Cfb). Local monthly temperatures were extracted from national meteorological records. Patients completed the International Prostate Symptom Score and 3-day frequency volume chart before undergoing free uroflowmetry with post-micturition volume measurement. Exclusion criteria were previous bladder outflow surgery and anti-cholinergic medication. Results: Data on 296 patients were suitable for analysis. Mean age was 62.3 years (range, 26-90). Over the period of study, the coldest month was January (mean = 4.7 degrees C) and the warmest month was August (mean = 15.8 degrees C). There was no significant variation in either International Prostate Symptom Score symptom scores by season (p>0.05) or any frequency-volume chart parameters, with the exception on an increase in median actual nightly voids over the summer months (p = 0.021). There was no significant correlation between maximal flow rate and post-micturition residual volumes and mean monthly temperatures (p>0.05). Conclusions: Seasonal variation in nocturia, but not other frequency-volume parameters, symptom severity or uroflowmetry parameters, is significant in men with lower urinary tract symptom. Future work should consider the impact of seasonal variation in lower urinary tract symptoms in both sexes across a wider range of climates.
