    ABSTRACT: OBJECTIVE: To investigate the prevalence and correlates of postmicturition urinary incontinence in Japanese men, and to compare with those of other types of urinary incontinence. METHODS: A total of 3224 male participants in a community-based survey were investigated. Three types of urinary incontinence were assessed; that is, postmicturition urinary incontinence, stress urinary incontinence and urge urinary incontinence. Age, body mass index, alcohol intake, cigarette smoking, and medical history of 18 diseases and conditions were the dependent variables for candidate correlates of the three types of incontinence. RESULTS: Unlike stress urinary incontinence and urge urinary incontinence, the prevalence of postmicturition urinary incontinence was constant throughout all generations (6.5% for the 30 s, 6.6% for the 40 s, 6.0% for the 50 s, 6.3% for the 60 s and 5.1% for the 70 s). The independent correlates for postmicturition urinary incontinence were asthma (P < 0.001; odds ratio 3.01), prostatic disease (P < 0.001; odds ratio 2.38), rhinosinusitis (P = 0.001; odds ratio 1.92), low back pain (P = 0.003; odds ratio 1.58), sleeplessness (P = 0.013; odds ratio 1.86), depression (P = 0.024; odds ratio 3.41) and body mass index (P = 0.025; odds ratio 0.73). CONCLUSIONS: Postmicturition urinary incontinence has different characteristics from those of stress urinary incontinence and urge urinary incontinence. Unlike stress urinary incontinence and urge urinary incontinence, postmicturition urinary incontinence is not age-dependent. Several diseases related to an allergic status, such as asthma and rhinosinusitis, are correlates for postmicturition urinary incontinence.

    ABSTRACT: AIMS: To investigate whether objective cardiovascular parameters have an independent association with nocturnal voiding in women. METHODS: Thirty-two parameters derived from questionnaires, and anthropometric, physiological and biochemical measures of 5,980 women were applied for analysis. Nocturnal voiding was assessed by the International Prostate Symptom Score and the Overactive Bladder Symptom Score. We measured variables including previously reported correlates of nocturnal voiding, such as age, a history of hypertension, and a history of diabetes, as well as those focusing on cardiovascular function, such as the cardio-ankle vascular index, the augmentation index, the ankle-brachial index, plasma B-type natriuretic peptide (BNP), and C-reactive protein (CRP). RESULTS: Age [odds ratio (OR): 1.058, P < 0.001], length of sleep (OR: 1.194, P < 0.001), sleeplessness (OR: 2.841, P < 0.001), urgency (OR: 1.528, P < 0.001), log(BNP) (OR: 2.031, P < 0.001), waist circumference (OR: 1.037, P = 0.002), body mass index (OR: 0.935, P = 0.007), menopause (OR: 1.503, P = 0.043), and history of hypertension (OR: 1.225, P = 0.029) were independently associated with nocturnal voiding ≥2 times. Age (β = 0.256, P < 0.001), urgency (β = 0.195, P < 0.001), sleeplessness (β = 0.181, P < 0.001), length of sleep (β = 0.088, P < 0.001), log(BNP) (β = 0.072, P < 0.001), waist circumference (β = 0.086, P < 0.001), and low-density lipoprotein-cholesterol (β = -0.038, P = 0.003) were significantly correlated with the severity of nocturnal voiding. CONCLUSIONS: Plasma BNP, which represents cardiac load, is strongly associated with the prevalence and severity of nocturnal voiding in Japanese women, as well as previously known correlates including age, urgency, quality and quantity of sleep, and obesity.

    ABSTRACT: To evaluate the usefulness of a quantification method using filter paper for analyzing minute voided urine of the mouse. Voided stain on paper (VSOP) method; the correlation between area of stained spot on a filter paper and amount of applied liquid was calculated. Voiding behavior of the mice was analyzed by placing the animal above the same filter paper and recording voided time and area over 2 hr. The usefulness of the VSOP method was tested in analysis of the voiding behavior of five female 7-week-old ddY mice treated with cyclophosphamide (CPM, 150 mg/kg, intraperitoneally) and five control ones, in comparison with the histology of CPM-induced cystitis. Further, the voided volume of male and female ddY mouse ranging from 2 to 13 weeks was assessed. There was a linear correlation between liquid volume and stained area on the filter paper (y = 16.472x - 22.411, R(2) = 0.9981). Between control mice and those with histologically proven CPM cystitis, there was a significant difference in voided volume (362.7 +/- 51.9 and 127.8 +/- 100.0 microl, < 0.001) and voiding interval (10.30 +/- 3.10 and 4.47 +/- 1.70 min, < 0.001). Voided volume of ddY mice was quantifiable from as early as 2-week old, increased along with their growth and correlated well with their body weight [(voided volume: microl) = 10.8 x (body weight: g) + 32, R(2) = 0.762]. The VSOP method is a useful tool for evaluating voiding behavior of the mouse, including those with small bladder capacity.

    ABSTRACT: We compared health-related quality-of-life (HRQL) after intensity-modulated radiotherapy (IMRT) with statuses obtained after old and new protocols of three-dimensional conformal radiation therapy (3DCRT) for localized prostate cancer. We measured the general and disease specific HRQL using the MOS 36-Item Health Survey (SF-36), and the University of California, Los Angeles Prostate Cancer Index (UCLA PCI), respectively. IMRT resulted in similar profiles of general and disease-specific HRQL to two other methods within the first year after treatment. Moreover, IMRT gave rise to comparable urinary, intestinal and sexual side effects despite the high dose of radiation applied.
