AIM: We evaluated differences between men and women with lower urinary tract symptoms (LUTS) combined with nocturia. METHODS: A total of 71 age-matched female-male pairs (median 58, range 20-81 years) who had moderate to severe LUTS and nocturia of more than once per night were enrolled in this study. RESULTS: In the younger group (<50 years), the International Prostate Symptom Score (I-PSS) results of the sexes were not significantly different. However, although total I-PSS results in the elderly group (> or =50 years) were not significantly different, quality of life index scores for women were higher (P = 0.002). On frequency-volume (FV) charts, mean total daytime voided volume (DVV) was significantly higher in younger men than in younger women (P = 0.017), but the mean nocturnal polyuria index (NPi) for women was higher than that for men (P = 0.047). However, maximum DVV (P = 0.009), mean DVV (P < 0.0001), total DVV (P < 0.0001), and mean nocturnal urine volume (P = 0.009) were significantly higher in elderly men than in elderly women. However, numbers of daytime voids were not different. CONCLUSION: Elderly women with LUTS have lower functional bladder capacities than elderly men, as suggested by their smaller mean voided volumes. However, no significant differences were observed between numbers of daytime voids, which was probably due to the smaller total daytime voided volumes of elderly women. In addition, although NPi for younger women and nocturnal urine volume for elderly men was higher, no other differences were observed in terms of other night-time parameters.  相似文献

PURPOSE: We determined the normal value of diurnal and nocturnal voiding frequency, and its determinants in a population based sample of elderly men. MATERIALS AND METHODS: We collected data on 1,688 men 50 to 78 years old recruited from the population of Krimpen, The Netherlands. Measurements consisted of self-administered questionnaires, including the International Prostate Symptom Score (I-PSS), a 3-day frequency-volume chart, transrectal prostatic ultrasound, uroflowmetry and post-void residual urine volume measurement. RESULTS: Diurnal voiding frequency is independent of age and more frequent in men with benign prostatic hyperplasia (BPH). Nocturia 2 or more times is present in 30% of men 50 to 54 and in 60% of those 70 to 78 years old, while nocturia 3 or more times is present in 4% and 20%, respectively. In addition, nocturia is strongly associated with BPH and nocturnal polyuria but apparently not with cardiovascular symptoms, hypertension or diabetes mellitus. We noted poor agreement of the responses on the frequency-volume charts and the I-PSS question on nocturia. Using the I-PSS leads to a higher prevalence of nocturia. CONCLUSIONS: Diurnal frequency is independent of age (median 5 voids, interquartile range 4 to 6) but higher in men with BPH. Nocturia increases with advancing age and is more frequent in men with nocturnal polyuria. BPH is an independent risk factor for nocturia and increased diurnal voiding frequency. In those with nocturia there is a great difference in subjective symptoms and objective data, indicating that the weight of the I-PSS question on nocturia for making treatment decisions should be reconsidered.  相似文献

Objective: To analyse possible associations between men’s likelihood of contacting a general practitioner (GP) for urological symptoms and the persistence of the symptoms, the influence on daily activities and the level of concern about the symptoms.

Design: Web-based nationwide cross-sectional questionnaire study.

Setting: The general population in Denmark.

Subjects: 48,910 randomly selected men aged 20+ years.

Main outcome measures: Urological symptom prevalence and odds ratios for GP contact with urological symptoms in regard to concern for the symptom, influence on daily activities and the persistence of the symptom.

Results: Some 23,240 men responded to the questionnaire, yielding a response rate of 49.8%. The prevalence of at least one urological symptom was 59.9%. Among men experiencing at least one urological symptom almost one-fourth reported contact to general practice regarding the symptom. Approximately half of the symptoms reported to be extremely concerning were discussed with a GP.

Conclusion: Increased symptom concern, influence on daily activities and long-term persistence increased the likelihood of contacting a GP with urological symptoms. This research points out that guidelines for PSA testing might be challenged by the high prevalence of urological symptoms.
  • Key points
  • ?The decision process of whether to contact the general practitioner (GP) is influenced by different factors, but contradictory results has been found in triggers and barriers for help-seeking with urological symptoms.

  • ??Increased symptom concern, influence on daily activities and long-term persistence consistently increased the likelihood of contacting a general practitioner with urological symptoms in men.

  • ??Only 50% of the symptoms reported to be extremely concerning were however discussed with the GP.

  • ??Guidelines for PSA testing might be challenged by the high prevalence of urological symptoms.

目的总结多系统萎缩(multiple system atrophy,MSA)以非运动症候和运动症候为首发症状的构成比和MSA非运动症候的具体症候构成比。方法选择MSA患者31例,其中MSA-P型18例,MSA-C型13例。进行详细病史记录和神经系统体检,记录运动症候及非运动症候具体表现及出现时间。结果 23例MSA以非运动症候首发。非运动症候的首发症状以快速眼动睡眠异常、排尿障碍、性功能障碍及直立性低血压常见。31例MSA患者均有非运动症候表现。以直肠功能障碍(93.5%)、排尿障碍(90.3%)、直立性低血压(64.5%)、睡眠呼吸暂停(61.3%)、快速眼动睡眠异常(48.4%)最为常见。MSA-P型与MSA-C型在年龄、性别、首发病程、就诊病程及非运动症候构成比较,差异无统计学意义(P>0.05)。结论 MSA患者普遍存在自主神经功能障碍等非运动症候表现,且以首发症状多见。MSA-C型患者中以非运动症候起病较MSA-P型患者更为多见。  相似文献
