Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH; in German guidelines: benign prostatic syndrome [BPS]) is the most frequent urological disease in men and can result in a considerable deterioration of quality-of-life. BPS can be associated with LUTS, benign prostatic enlargement (BPE), and bladder outlet obstruction (BOO) or benign prostatic obstruction (BPO), respectively. The expert group on BPS of the German Society of Urology has re-evaluated the tests for the assessment of BPH and provides evidence-based recommendations. OBJECTIVES Presentation and evidence-based rating of tests for the assessment of patients with BPS. MATERIALS AND METHODS Summary and overview of chapters 5, 6, and 8 of the latest long version of the German S2e guideline on BPS. RESULTS The diagnostic work-up should clarify (1) whether the complaints of the patient are caused by BPS, (2) how relevant the complaints are and whether treatment is necessary, (3) whether complications of the lower or upper urinary tract already exist, and (4) which treatment will be most suitable. Baseline assessment should be done in all BPS patients and include history, measurement of LUTS and quality-of-life, urinalysis, serum prostate-specific antigen, post-void residual, ultrasound of the lower urinary tract, including measurements of prostate volume, intravesical prostatic protrusion and detrusor wall thickness, and ultrasound of the upper urinary tract. Additional tests can follow when questions remain unanswered after baseline assessment. These optional tests include bladder diaries, uroflowmetry, serum creatinine, urethrocystoscopy, other noninvasive tests for the determination of BOO/BPO such as penile cuff test, condom catheter method and near-infrared spectroscopy, and other imagining tests such as X‑ray and MRI investigations. CONCLUSIONS The updated German S2e guideline summarizes evidence-based recommendations on the diagnostic work-up, including the assessment of the BPS components BPE, LUTS, and BOO/BPO.

Abstract
Purpose The effects of an anticholinergic or antidiuretic agent as add-on therapy to an alpha-blocker for lower urinary tract symptoms (LUTS) according to a voiding diary in 3 days are unknown. We prospectively investigated the efficacy of an anticholinergic or antidiuretic agent as add-on therapy for nocturia in men previously treated with an alpha-blocker for LUTS. Subjects and methods Patients were randomly subdivided into two groups. All patients had a 4-week washout. Group A had alpha-blocker for 4 weeks, then an alpha-blocker plus an anticholinergic agent for 4 weeks, and, finally, 4 weeks of an alpha-blocker plus an antidiuretic agent. Group B had an alpha-blocker for 4 weeks, then an alpha-blocker plus an antidiuretic agent for 4 weeks, and, finally, 4 weeks of an alpha-blocker plus an anticholinergic agent. In both groups, patients were subdivided into nocturnal polyuria, decreased nocturnal bladder capacity (NBC), or nocturia by both causes subgroups. A 3-day voiding diary, total International Prostate Symptom Score (IPSS), IPSS sub-scores, Overactive Bladder Symptom Score, uroflowmetry, and post-void residual urine volume, were assessed at baseline, and at 4, 8, and 12 weeks. Results A total of 405 patients completed the study. During treatment, the changes from baseline in total IPSS and IPSS sub-scores were significantly decreased at 4 weeks and were maintained for 12 weeks. In the nocturnal polyuria subgroup of Groups A and B, the number of episodes of nocturia in 3 days, nocturnal urine volume, and nocturnal index were significantly decreased using an alpha-blocker plus an antidiuretic agent. In the decreased NBC subgroup of Groups A and B, IPSS storage sub-score, Overactive Bladder Symptom Score, number of episodes of nocturia in 3 days, number of episodes of urgency in 3 days, and NBC index were all significantly decreased using an alpha-blocker plus an anticholinergic agent. Conclusion An anticholinergic agent or antidiuretic agent as an add-on therapy in men previously treated with an alpha-blocker improves nocturia including LUTS.

Abstract
PURPOSE We determined the relationship between nocturia and nocturnal polyuria. MATERIALS AND METHODS The PubMed® and Embase® databases were searched for studies written in English, German, French or Dutch with original data on adult participants in an investigation of the relationship between nocturia and nocturnal polyuria. A meta-analysis of the difference in mean nocturnal voiding frequencies between patients with and without nocturnal polyuria was conducted. Nocturnal polyuria risk was compared between participants with and without nocturia, and the resulting odds ratio was subsequently converted to relative risk with 95% CIs. RESULTS From 511 references identified we selected 78 publications of 66 studies, 15 of which met the inclusion criteria for this study. Quality scores of studies were generally high for internal validity but low for external validity. In 7 studies (1,416 participants) we estimated a standardized mean difference of 0.59 (95% CI 0.29-0.89) for nocturnal voids between nocturnal polyuria and nonnocturnal polyuria cases. In 8 other studies (with 2,320 participants) we calculated a pooled OR of 4.99 (3.92-6.37) for nocturnal polyuria in individuals with nocturia. The corresponding RR, based on a nocturnal polyuria risk in the pooled population of 63.8%, was 1.41 (1.37-1.44). CONCLUSIONS The association between nocturia and nocturnal polyuria is apparent and robust. However, the clinical importance of the association appears to be less obvious than previously suggested based on single studies. The observed high prevalence of nocturnal polyuria, as a result of the applied International Continence Society definition, may be responsible for this discrepancy.

Abstract
Benign prostatic hyperplasia (BPH) is a very common condition, related to aging and causing symptoms, called lower urinary tract symptoms. On account of its huge prevalence, it is important for clinicians who are involved in the management of patients with BPH to be aware of the very strict recommendations for BPH evaluation. In this article, we describe the different steps and procedures doctors should follow to evaluate these patients; symptoms and signs of BPH are reviewed, as well as the clinical evaluation steps and examinations available. The basic evaluation of the patients with BPH should include, according to the recommendations of the most relevant international guidelines, lower urinary tract symptoms evaluation with appropriate symptom scores, digital rectal examination, voiding charts, prostate-specific antigen and creatinine measurement, urinalysis, and imaging of the urinary tract.

Abstract
PURPOSE We sought criteria for nocturnal polyuria in asymptomatic, nonurological adults of all ages by reporting reference values of the ratio of daytime and nighttime urine volumes, and finding nocturia predictors. MATERIALS AND METHODS Data from a database of frequency-volume charts from a reference population of 894 nonurological, asymptomatic volunteers of all age groups were analyzed. The nocturnal polyuria index and the nocturia index were calculated and factors influencing these values were determined by multivariate analysis. RESULTS The nocturnal polyuria index had wide variation but a normal distribution with a mean ± SD of 30% ± 12%. The 95th percentile of the values was 53%. Above this cutoff a patient had nocturnal polyuria. This value contrasts with the International Continence Society definition of 33% but agrees with several other reports. On multivariate regression analysis with the nocturnal polyuria index as the dependent variable sleeping time, maximum voided volume and age were the covariates. However, the increase in the nocturnal polyuria index by age was small. Excluding polyuria and nocturia from analysis did not alter the results in a relevant way. The nocturnal voiding frequency depended on sleeping time and maximum voided volume but most of all on the nocturia index. CONCLUSIONS The prevalence of nocturnal polyuria is overestimated. We suggest a new cutoff value for the nocturnal polyuria index, that is nocturnal polyuria exists when the nocturnal polyuria index exceeds 53%. The nocturia index is the best predictor of nocturia.

Abstract
Purpose The precise etiology and classification of nocturia in women is not enough. We evaluated age related changes and classified the type of nocturia by age in women. Methods We included 118 women 20 years or older with nocturia at least one time during night time. Subjects were divided into three groups by the age: group 1, under 40 years; group 2, 40 through 59 years; group 3, 60 years and above. The causes of nocturia and its pattern changed by age in women were evaluated using 3 days frequency volume chart. Nocturia was devided into three types: nocturnal polyuria, decreased nocturnal bladder capacity and mixed type. Results The mean age was 57.2±11.8 and the mean nocturnal frequency was 2.7±1.8. In all age group, noctural polyuria was the major cause for noturia (40.8%), followed by low nocturnal bladder capacity (23.7%). As a major cause of nocturia, there was a significant increase of the incidence of nocturnal polyuria in aged people: group 1, 32.4%; group 2, 41.0%; group 3: 47.6% (P<0.04). Conclusions Nocturnal polyuria and decreased nocturnal bladder capacity are the major causes of nocturia in women. Nocturnal polyuria was the major cause of nocturia with age over 60 years old. In aged women, nocturnal polyuria should be considered as a main cuase of nocturia and treated based on these result.

Abstract
STUDY TYPE Symptom prevalence (prospective cohort). LEVEL OF EVIDENCE 1b. OBJECTIVE To measure the test-retest reliability of a 7-day bladder diary incorporating the Patient's Perception of Intensity of Urgency Scale (PPIUS), and to establish the normal values of the scale in a population of asymptomatic women. SUBJECTS AND METHODS Women volunteers, aged > or =18 years, were screened with the International Consultation on Incontinence Modular Questionnaire - Female Lower Urinary Tract Symptoms Long Form, to exclude those with bothersome lower urinary tract symptoms. Participants completed two separate 7-day bladder diaries with a 1-week interval between. Reliability was assessed using intraclass correlation, Spearman's correlation, and Student's t-test. RESULTS Forty volunteers were recruited. Most (67.5%) reported no urgency episodes. Convenience voids accounted for 26.8% of all voids. There was a significant positive effect of age (r = 0.34, P = 0.034) on urgency episodes, but no effect on mean urge scores (r = -0.03, P = 0.843). The reliability of assessment of frequency (0.86), nocturia (0.84), and the mean urge scores (0.85), were better than the reliability of assessment of urgency episodes (0.56), which occurred infrequently. The 95th centile for daily urinary frequency was 7.27 and for weekly urgency episodes was 2.00. CONCLUSION The PPIUS is a reliable tool for assessing urinary urge sensation in women. Inclusion of this measure in bladder diaries does not compromise the recording of other variables.

Abstract
BACKGROUND/AIM Nocturia often occures in patients with benign prostata hyperplasia (BPH). The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. METHODS Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Simptoms were evaluated with the International Prostete Sypmtom Score before, as well as three and six months after the surgery. All the results were compared with the control group. RESULT . There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, howerer, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. CONCLUSION There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favourable result of the surgery because of a significant correlation between noctura and the age of a patient.

Abstract
The overall evidence of an association between fluid intake and bladder cancer is not entirely consistent. We examined the fluid intake-bladder cancer relationship in the Los Angeles bladder cancer case-control study. A total of 1,586 cases and their age-, sex-, and race-matched neighborhood controls were interviewed in-person from 1987 to 1999. Information on total fluid intake was derived from the consumption of specific fluids including water, coffee, tea, alcohol, milk, juice, hot chocolate and soda. Total fluid intake was not associated with bladder cancer. Daily water intake was associated with a slight decrease in bladder cancer risk, with the protection more pronounced among women (p for trend = 0.039) than among men (p for trend = 0.62). Compared to drinking <1 glass of water per day, drinking > or =6 glasses/day was associated with 0.91 (95% confidence interval, 0.67-1.22) times the risk of bladder cancer among all subjects, 0.94 (0.67-1.32) times the risk among men, and 0.69 (0.36-1.33) times the risk among women. The water intake-bladder cancer association also seemed to be modified by daytime urination frequency with significant inverse association among subjects who urinated > or =6 times/day (p for trend = 0.015), but not among those who urinated less frequently. Similarly, the protection from water intake was confined to women who did not experience nocturia and to men who did. Results from our study suggest that water intake may be associated with a slight reduction in bladder cancer risk.

Abstract
BACKGROUND We evaluated the impact of stress urinary incontinence (SUI) and overactive bladder (OAB) on health-related quality of life (HRQOL) and sexual function. METHODS A total of 245 women (SUI; n = 123 and OAB; n = 122) from 21 to 79 years old (mean 50.4) were included in the primary analyses. To obtain HRQOL and sexual function assessments, patients were asked to fill in the 'Bristol Female Lower Urinary Tract Symptoms (BFLUTS)' and the 'Medical Outcomes Study Short Form (SF-36)' questionnaires. RESULTS Of the eight domains in the SF-36 questionnaire, only 'general health' was significantly different between the groups. Patients with SUI had a better general health than those with OAB (P = 0.016). When comparing the BFLUTS scores in the two groups, the score for 'BFLUTS-filling symptoms' was higher in the OAB group (P = 0.002) but that for 'BFLUTS-incontinence symptoms' was higher in the SUI group (P < 0.001). The score for 'BFLUTS-sex' was higher in the SUI group than in the OAB group but this was not statistically significant (P = 0.096). Of the 169 patients who had a sex life, the SUI group had experienced pain (P = 0.033) and leakage (P = 0.056) more frequently during intercourse than the OAB group. CONCLUSION Both SUI and OAB have a detrimental impact on patient HRQOL in Korean women. In addition, our findings suggest that women with SUI had more frequently experienced pain during intercourse and coital incontinence than those with OAB.

Abstract
The urine-concentrating mechanism performs one of the most essential functions in water and electrolyte metabolism and serves primarily to maintain extracellular osmolality within a very narrow range. The history of anti-diuresis dates back more than 100 years and includes the discovery of antidiuretic hormone (AVP), the renal AVP receptor, and most recently the water channel (aquaporin) proteins. Today, the mechanisms of antidiuresis are understood on a highly detailed molecular level including both short term and long-term regulation of AQP2 function. Furthermore, the background behind many acquired and inherited disturbances of water balance has now been revealed and has enabled a precise differential diagnosis. These include different forms of diabetes insipidus, nocturnal enuresis and nocturia in the elderly. Diabetes insipidus represents a dramatic but rare disturbance of water balance caused by deficient AVP secretion (neurogenic), reduced renal sensitivity to AVP (nephrogenic), an abnormally high fluid intake (primary polydipsia), or in rare cases by placental enzymatic degradation of AVP (gestational). Nocturnal enuresis and nocturia in the elderly represents much more common disturbances and share common pathogenic features including an abnormally high nocturnal urine production. This seems at least in part to be caused by abnormally low levels of plasma AVP during night. The increased understanding of such water balance disturbances have changed dramatically prior treatment practice by introducing antidiuresis as a treatment modality. The ongoing progress in our understanding of antidiuresis may provide the basis for the development of new antidiuretic compounds.

Abstract
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.

Abstract
PURPOSE Nocturia is caused by increased nocturnal urine output (nocturnal polyuria) and/or diminished nocturnal bladder capacity. We retrospectively evaluated the causes of nocturia in patients with overactive bladder and nocturia. MATERIALS AND METHODS A total of 850 patients (18 years or older) with symptoms of overactive bladder (8 or more micturitions per 24 hours and urgency or urgency urinary incontinence) and nocturia (mean of 2.5 or more episodes per night) were enrolled in a 12-week study of tolterodine ER (4 mg QD) vs placebo. Of this total 845 patients (417 men and 428 women) completed 7-day bladder diaries. Patients were stratified post hoc by sex and age groups (less than 50, 50 to 70, more than 70 years). Indices of nocturnal urine production (nocturia index, nocturnal polyuria index and nocturnal bladder capacity index) were compared using ANOVA (alpha level 0.05). Higher nocturia index and nocturnal polyuria index values suggest that nocturia occurs because of nocturnal urine overproduction. Higher nocturnal bladder capacity index values suggest that nocturia occurs because of decreased nocturnal bladder capacity. RESULTS There were no statistically significant gender or age related differences in baseline nocturnal micturitions. Nocturia index increased significantly with age (p <0.0001), and values were significantly higher among men than women for all age groups (p = 0.0064). Nocturnal polyuria index increased significantly with age (p <0.0001) and there were no gender differences. For nocturnal bladder capacity index there was a significant decrease with advancing age among men (1.75 greater than 1.16 greater than 0.90) and women (1.53 greater than 1.42 greater than 1.08, P(interaction) = 0.0148). CONCLUSIONS In younger patients with overactive bladder, decreased nocturnal bladder capacity has a greater role in the pathogenesis of nocturia symptoms, whereas in older patients increased nocturnal urine output has a greater role.

Abstract
OBJECTIVE To describe and compare the patterns of nocturia in Asian and Caucasian men presenting with lower urinary tract symptoms (LUTS), and to identify associations or correlations between LUTS and variables from a frequency-volume chart (FVC), as nocturia is common among men with LUTS, and analysis of FVCs shows nocturnal polyuria and reduced nocturnal bladder capacity (NBC) as the predominant causes in Western patients, but there are few comparisons with other ethnic groups. PATIENTS AND METHODS Consecutive men aged > or = 40 years, presenting with LUTS and nocturia to an Asian and a Caucasian tertiary centre, were recruited prospectively. The men completed the International Prostate Symptom Score and a 3-day FVC. Men having had bladder outlet surgery and/or receiving anticholinergics were excluded. We computed the nocturia ratio, i.e. the nocturnal urine volume/ 24-h urine volume, nocturia index, predicted nocturnal voids and NBC index (NBCI), and analysed comparisons and correlations. RESULTS In all, 93 Asian and 200 Caucasian men were recruited prospectively, with a similar age and overall severity of LUTS. The nocturia ratio was larger in the Caucasian men, whereas the NBCI was larger in the Asians (P < 0.001). The prevalence of nocturnal polyuria in men aged > or =60 years (nocturia ratio > or =0.3) was significantly higher in the Caucasian population. Conversely, the prevalence of reduced NBC appeared to be higher in the Asians (based on a NBCI of >2; P < 0.001). CONCLUSIONS The patterns of nocturia and FVC variables differed significantly in age-matched Asian and Caucasian groups. There are also possible ethnic differences in the causes of nocturia, with nocturnal polyuria being more prevalent in Caucasians.

Abstract
A frequency volume chart is a simple, easy-to-use, non-invasive tool that is useful in the assessment of patients with lower urinary tract symptoms. Though more sophisticated techniques are now available for diagnosis, the frequency volume chart should still be considered the first line investigation. In this review we summarize the indications and value of this age old investigation. Urologists and primary care physicians should use the frequency volume chart more frequently in their practice.

Abstract
AIMS To investigate bladder diary measurements from asymptomatic subjects in separate night and day periods, including their relationships to age and total volume voided. A major objective of this study was to generate age-adjusted reference values against which clinical measurements of nocturia can be compared. MATERIALS AND METHODS Three-day bladder diaries were collected from 161 females and 92 males (age: median=46.5 years; range=19.6-84.6 years). We studied: average volume voided ("Vavg"), voiding frequency, and four urine production measures (volume, production rate, and their ratios to 24-hr values) RESULTS Both day and night Vavg and frequency increase with increasing volume. The night increase is much steeper than the day increase. With aging, frequency increases, Vavg decreases, day production decreases and night production increases. These age effects are steeper for males than females. Adjusting for age by regression analysis reduces the night production measure's variability by about 40%, and expressing production rate as a percent of the 24-hr value reduces the variability by an additional 20%. CONCLUSIONS We present regression equations that can be used to adjust night and day Vavg frequency and production rate reference values for the influences of age and total volume. Using these equations, we calculated a table of 95% confidence limits of night urine production and night frequency. The least variable night urine volume measurement studied was night/24-hr production rate; hence this may prove to be the most efficacious measurement to use in detecting nocturnal polyuria.

Abstract
OBJECTIVE To compare the quality of data recorded in urinary diaries completed for 3 days compared with those completed for 7 days. METHODS Men and women enrolled in a randomized study of a nurse-led intervention for urinary incontinence were eligible for the study. Participants completed either a 7-day diary or a 3-day diary at baseline and after 8 weeks of the trial intervention. Data quality was assessed by categorizing each day as complete or incomplete. Incomplete days were those with fewer than four entries and those with obvious discrepancies from the rest of the diary days. Data were compared by percentage differences with 95% confidence intervals (95% CI). RESULTS Two hundred forty-eight patients completed the 3-day diary, and 40 patients competed the 7-day diary. The majority of the respondents were women. There were more completed 3-day diaries (90.7%) compared with 7-day diaries (50%) (difference 40.7%, 95% CI 28.8-52.6%). When compared with the first 3 days of the 7-day diary, the 3-day diary contained more complete data (90.7% versus 65%; difference 25.7%, 95% CI 14.6-36.9%). These differences were seen in all data types except nocturnal incontinence. There was no evidence of association between diary completion and demographic characteristics. CONCLUSION Our data demonstrated that the 7-day diary included less complete data than the 3-day diary, even in the first 3 days of the longer diary. This finding suggests elements of both diary "fatigue" and also diary "despair" may be acting. We would suggest that a 3-day diary is superior in terms of data quality. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION The objective of this study was to examine the impact of self-perceived bothersomeness of overactive bladder (OAB) symptoms on the health-related quality of life (QOL). PATIENTS AND METHODS A total of 92 women with a mean age of 53.3 (range 23-79) years suffering from OAB were included in the study. The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and King's Health Questionnaire (KHQ) were used to assess the QOL. The patients were divided into two groups according to the bothersomeness degree of OAB: 'low' and 'moderate' to 'high'. RESULTS The SF-36 and the KHQ scores of the patients were significantly different from those of the controls (p <0.05), except for three domains of the SF-36. No difference in the results of the frequency-volume charts was observed between the two patient groups. The scores of the SF-36 and the KHQ domains did not correlate with the data of the frequency-volume charts. Significant differences were found between the two patient groups for most domains of the SF-36 (p <0.05). Significant differences were also detected in most domains of the KHQ (p <0.05). CONCLUSIONS Objective data are not a sensitive tool for measuring the QOL in women with OAB symptoms. Our findings suggest that patient-perceived bothersomeness significantly influences QOL and that strategies for assessing bothersomeness should be developed to evaluate the QOL in these patients.

Abstract
OBJECTIVE To determine how the reliability of frequency-volume charts (FVCs) vary with their duration when used to assess patients with lower urinary tract symptoms (LUTS) and whether the duration influences patient compliance. METHODS Peer-reviewed studies involving patients with LUTS were searched systematically, with the selected studies assessed for their internal and external validity and statistical quality. Details of the patients and type of FVC used were summarized, and reliability coefficients and levels of compliance were extracted for commonly assessed FVC variables. RESULTS In all, 13 studies were considered to meet the review criteria; they assessed the reliability of FVCs lasting 1, 2, 3 and 7 days. The reliability coefficients for 3- and 7-day FVCs were generally >0.8; those for shorter charts tended to be lower, but strong conclusions could not be drawn due to study limitations. There was no obvious relationship between the duration of the FVC and the level of compliance. CONCLUSIONS Strong recommendations cannot be made about what duration of an FVC should be used to assess or monitor patients with LUTS. The current consensus on using FVCs of > or = 3 days seems to be the most defensible policy, but more research of high quality is required, especially into the relationship of FVC duration with compliance.

Abstract
OBJECTIVES To determine the significance of nocturnal hesitancy in the treatment of men with lower urinary tract symptoms. METHODS A total of 123 patients with nocturia were prospectively studied. The nocturnal hesitancy scores ranged from 0 to 5 and were scored according to the International Prostate Symptom Score. The patients were stratified on the basis of their nocturnal hesitancy scores as group 1 (0 to 1, n = 57), group 2 (2 to 3, n = 45), and group 3 (4 to 5, n = 21). All patients received treatment with an alpha-blocker once daily for 4 weeks. RESULTS Group 3 scored significantly higher on the International Prostate Symptom Score at baseline and after treatment than did group 1. The actual number of nightly voids was greatest in group 3 and was lowest in group 1 (P = 0.011 at baseline and P = 0.046 after treatment, respectively). The baseline nocturia indexes were greatest in group 3 and were lowest in group 2 (P = 0.027). A significant but weak correlation was also noted between the nocturia hesitancy score and the differences in scores between the posttreatment and baseline voiding symptoms (r = -0.234, P = 0.021) and total International Prostate Symptom Score (r = -0.270, P = 0.011), respectively. In our multivariate analyses, the straining score was a significant determinant of nocturnal hesitancy. CONCLUSIONS The results of our study revealed that more emphasis should be placed on nocturnal hesitancy in the terminology of lower urinary tract symptoms. Additional research regarding the pathophysiologic mechanisms underlying nocturnal hesitancy, as well as its effects on those with it, is clearly warranted.

Abstract
OBJECTIVE To determine the efficacy of an alpha-adrenoceptor antagonist, terazosin, in reducing nocturia in men with lower urinary tract symptoms (LUTS), and to identify the factors predicting treatment outcome. PATIENTS AND METHODS In all, 100 patients were treated with 2 mg of terazosin once daily for the first 7 days, and continued to receive 4 mg of terazosin once daily for the following 3 weeks. The men were assessed at baseline and at the end of treatment using uroflowmetry, the International Prostate Symptom Score (IPSS), and the degree of nocturia estimated from a frequency-volume chart (FVC) and objectively. RESULTS On the FVC, 27 patients reported that the terazosin treatment reduced their nocturia by more than half, and 14 reported a reduction of 25-49%. On the IPSS, 31 patients reported that the treatment reduced their nocturia by more than half and 27 reported a reduction of 25-49%. On multivariate regression analysis, only the actual number of nightly voids on the FVC was associated with a 2.1-fold chance of an improvement of >25% in objective nocturia (P = 0.016). Using a comparable model, a greater nocturia score on the IPSS was associated with a higher likelihood of improvement in subjective nocturia (odds ratio, 1.653; 95% confidence interval, 1.079-2.533; P = 0.021). CONCLUSION Treatment with terazosin can reduce patients' episodes of nocturia both subjectively and objectively in some men with LUTS. Our results suggest that both subjective and objective numbers of nocturia episodes are associated with improvements in subjective and objective nocturnal frequencies, respectively.

Abstract
We examined the impact of stress urinary incontinence (SUI) and overactive bladder (OAB) on micturition habits and health-related quality of life (QOL). A total of 250 Korean women were included in the study. The Medical Outcomes Study Short Form (SF-36) and the King's Health Questionnaire (KHQ) were used to assess QOL in the patient (SUI, n=158 and OAB, n=92) and control (n=70) groups. A control group was recruited at the Health Promotion Center of our hospital. Each of the dimension scores in the SF-36 represents better health, while that of the KHQ does worse health perception. On the frequency-volume charts, patients with OAB had more nighttime voids than those with SUI (P=0.001). Of the eight domains in the SF-36 questionnaire, four domains were significantly different between the control and OAB groups. Patients with SUI had a significantly lower score on one domain than the controls. Between the SUI and OAB groups, only one domain showed a significant difference. Regarding the KHQ, all domain scores in control subjects were significantly lower than those in the SUI and OAB groups. Between the SUI and OAB groups, the OAB group had higher scores on 'general health perception' and 'sleep/energy disturbances', while the scores of 'physical limitations' and 'severity measures' were higher in the SUI group. Women with OAB have a higher number of nocturic episodes than those with SUI, but the QOL is not less affected by SUI than by OAB. Furthermore, simultaneous disease-specific QOL instruments should be used in the evaluation of urinary incontinence because the generic QOL instrument is not a sensitive tool for measuring QOL in this population.

Abstract
OBJECTIVES To determine whether the voiding symptom questionnaire provides information regarding nocturia as accurate as that provided by frequency-volume (FV) charts, we evaluated patients with lower urinary tract symptoms. METHODS We prospectively analyzed 164 patients (62 men and 102 women, mean age 53.6 years, range 20 to 83) referred for the evaluation of lower urinary tract symptoms. At the initial visit, all patients answered the International Prostate Symptom Score (IPSS) questionnaire to quantify nocturia and subsequently were requested to complete a 3-day FV chart. RESULTS The differences in age between the men and women were not statistically significant. The total IPSS and IPSS bother scores were similar between the sexes. For all patients, the actual number of nightly voids in the FV charts and the IPSS nocturia score were modestly intercorrelated (r = 0.609, P <0.001). However, large individual differences were found in the nighttime diuresis rate (67.7%) between the IPSSs and FV charts. No statistically significant differences were found between men and women, but agreement was achieved in only 39.2% of patients younger than 60 years old and 22.4% of those 60 years old or older for the number of voids per night recorded by the FV charts and reported by the IPSS (P = 0.024). Overestimation of the number of nocturic episodes in the IPSS was more common than underestimation, especially in patients 60 years old or older (P = 0.014). CONCLUSIONS The findings of the present study revealed poor agreement between the subjectively estimated nocturnal frequency and chart-determined nocturnal frequency. Our results suggest that FV charts should be included as an integral part of evaluating nocturia in both sexes.

Abstract
AIMS Voiding diary duration may be related to patient compliance and burden. To test this hypothesis, we evaluated patient compliance and burden. METHODS Between January and July 2002, we prospectively evaluated 162 patients (57 males and 105 females, mean age 53.0, range 20-81 years) with stress urinary incontinence or lower urinary tract symptoms. At the initial visit, all patients underwent a detailed clinical evaluation including an International Prostate Symptom Score (I-PSS) assessment and were randomly requested to complete 2-day, 3-day, or 7-day voiding diaries (the three study groups). At the second visit, a simple self-administered questionnaire was completed by all patients. The questionnaire included 11 items on subject demographics and voiding diary-keeping. RESULTS No significant differences were found in either the accuracy of diary-keeping or the daily average number of omissions when the three groups were compared. However, as the diary duration increased, the mean burden scores increased (P = 0.005), and the mean preferred duration of the diary in the 7-day group was significantly higher than that of the 2-day or 3-day groups (P < 0.001). After categorizing patients into two groups according to the degree of patient burden, members of the group with a greater perceived burden were found to have a significantly higher I-PSS quality of life score (P = 0.045) and to have kept a diary for a longer time (P = 0.038). CONCLUSIONS Our results suggest that keeping a diary for 7 days may increase patient burden and thus, we recommend that the 7-day diary should be reduced to cover fewer days.

Abstract
OBJECTIVE To determine the age prevalence of nocturnal polyuria among older women in the community, and to investigate the relationship between nocturnal polyuria and nocturia. PATIENTS AND METHODS In all, 1183 women aged > or = 50 years, who were registered with a family doctor practice and who had taken part in a prevalence study, were sent brief questionnaires and a frequency/volume chart (FVC) to complete. RESULTS There were 227 FVCs with adequate data and 264 completed questionnaires available for analysis. The prevalence of nocturnal polyuria increased disproportionately with age. There was no clear relationship between nocturia or nocturnal polyuria and daytime frequency, nor was there a clear relationship between diuretic use and nocturnal polyuria. CONCLUSION Nocturnal polyuria is common among women in the community and not obviously related to daytime frequency. Night-time symptoms are common in women as well as men, and are troublesome to them.

Abstract
OBJECTIVE To determine whether diurnal voiding patterns predict nocturia in patients with lower urinary tract symptoms (LUTS), as few studies have evaluated the association between diurnal and nocturnal voiding patterns. PATIENTS AND METHODS We prospectively analysed the frequency-volume charts (FVCs) of consecutive patients with LUTS. At the initial visit patients had a detailed clinical evaluation and subsequently were requested to complete a 72-h FVC. In all, 104 (41 men and 63 women, mean age 63 years, range 50-83) were included in the primary analyses. Associations between daytime variables and nocturia were described using maximum likelihood estimates of the relative risk and by 95% confidence intervals (CIs) based on logistic regression models. RESULTS When at least one night-time void was used to define nocturia the multivariate logistic model showed a negative association of mean daytime voided volume with nocturia (P = 0.001). The odds ratio for nocturia decreased with this variable to 0.98 (95% CI 0.96-0.99). When 'voiding at least twice per night' was used to define nocturia only the number of daytime voids was positively related to nocturia (odds ratio 1.22; 95% CI 1.01-1.48; P= 0.040). CONCLUSION Nocturia may be associated with diurnal voiding patterns; these results also suggest that the causes of nocturia of one or of two or more voids may differ. This highlights the role of bladder function in more severe forms of nocturia.

Abstract
PURPOSE Nocturia is a common condition often attributed in aging men to benign prostatic enlargement. Older adults are prone to nocturnal sleep disturbance, of which disturbed circadian rhythm may be a component since it improves with nighttime administration of melatonin. This study was designed to investigate melatonin as a potential treatment for nocturia associated with bladder outflow obstruction in older men. MATERIALS AND METHODS A total of 20 men with urodynamically confirmed bladder outflow obstruction and nocturia were entered into a randomized, double blind, placebo controlled crossover study assessing the effect of 2 mg controlled release melatonin at night on nocturia. Symptoms were assessed at baseline and after each 4-week treatment period using a frequency volume chart, the International Prostate Symptom Score and symptom problem index. Maximum urinary flow rate and post-void residual urine volume were also assessed. RESULTS Baseline frequency of nocturia was 3.1 episodes per night. There were 7 men (35%) with detrusor overactivity and 10 (50%) had nocturnal polyuria. Melatonin and placebo caused a decrease in nocturia of 0.32 and 0.05 episodes per night (p = 0.07) and a decrease in the nocturia bother score of 0.51 and 0.05, respectively (p = 0.008). Nocturia responder rates (a reduction from baseline of at least -0.5 episodes per night) differed between the active medication and placebo groups (p = 0.04). Daytime urinary frequency, International Prostate Symptom Score, relative nocturnal urine volume, maximum urinary flow rate and post-void residual were unaffected by melatonin treatment. CONCLUSIONS Melatonin treatment is associated with a significant nocturia response rate, improvement in nocturia related bother and a good adverse effect profile. However, it is uncertain whether the observed changes in this study are clinically significant.

Abstract
AIMS There is wide variation in the number of days necessary to maintain a diary and still furnish reliable data on which to base a sound clinical assessment. Estimates range from 1 day to 2 weeks, 7 days probably being the criterion standard. The goal of this retrospective study was to evaluate how much the 7-day period could be shortened without compromising the reliability of data. METHODS Various lengths of frequency-volume (FV) charts (from 1 day to 6 days) were compared with the standard 7-day charts on 14 FV parameters. RESULTS Overall results show that a 4-day dairy is nearly identical to the 7-day chart (most r > or = 0.95). Results of the 1-, 2-, and 3-day charts were frequently different statistically from the 7-day chart, whereas comparison of the 4-day chart with the 7-day chart showed no statistically significant differences. In addition, results of 4-day FV charts from a new control cohort showed no significant differences from the 7-day charts of the main cohort. CONCLUSIONS In conclusion, our study indicates that the 4-day chart is as reliable as the 7-day chart. This reduction in the length of time, although easier for the patients, does not compromise the diagnostic value of the FV charts.

Abstract
OBJECTIVE To evaluate differences between elderly people with and without nocturia (waking up in the night to void) in terms of voiding habits, urine production and voided volumes. SUBJECTS AND METHODS Nocturics or= two voids/night) and non-nocturics (< one void/night) were recruited from a questionnaire survey. Subjects were asked to complete a 3-day frequency-volume chart, including time and volume of each void, and their bedtime and waking time. Diaries from 108 non-nocturics and 116 nocturics were analysed. The number of voids, urine production, largest and average voided volumes were analysed using repeated-measures analysis of variance models, controlling for variables such as age, gender, body weight and gender-diagnosis interaction. RESULTS Nocturnal urine volume was higher in nocturics than in non-nocturics. The difference between the groups was larger among the men (estimated difference 384 mL) than among the women (227 mL), but highly statistically significant (P < 0.001) in both genders. Among the men the diurnal urine and 24-h urine volumes were significantly higher in nocturics (difference, diurnal 131 mL, 24-h 462 mL, both P < 0.001). In the women the diurnal urine volume was lower in nocturics than in non-nocturics (difference 147 mL P = 0.0022) with no difference detected in 24-h urine volume. The largest voided volume was significantly less in nocturics than in non-nocturics; the difference was larger in women (128 mL, P < 0.001) than in men (42 mL, P = 0.0027). The average voided volume was 85 mL less (P < 0.001) in nocturics. The overlap between the groups in nocturnal urine and voided volumes was substantial and several significant covariates identified. The ratio between nocturnal urine volume and largest voided volume was the most statistically significant predictor of the number of nocturnal voids. CONCLUSION Elderly nocturics had a higher nocturnal urine production and lower volume per void than non-nocturics. Differences between nocturics and non-nocturics in urine production and largest voided volume did not follow the same pattern in men and women. Nocturia was a result of a mismatch between nocturnal urine volume and largest voided volume, rather than abnormal values in either. The treatment of nocturia should be directed at one or both of these factors, depending on the findings from the 3-day frequency-volume chart of the individual.

Abstract
OBJECTIVES To describe the normal values for nocturnal urine production and its determinants, as well as the relation between nocturnal urine production and voiding frequency. METHODS Data were collected from 1688 men aged 50 to 78 years without bladder or prostate cancer, radical prostatectomy, neurogenic bladder dysfunction, or negative advice from their general practitioner. Measurements included self-administered questionnaires, a 3-day frequency-volume chart, transrectal ultrasonography of the prostate, uroflowmetry, and postvoid residual urine volume measurement. The mean nocturnal urine production was computed from the frequency-volume charts. Linear regression analyses were performed to determine associated factors for nocturnal urine production. Areas under the receiver operating characteristic curves were used to describe the discriminative value of nocturnal urine production on nocturnal voiding frequency. A cutoff value for "increased" nocturnal urine production was defined using logistic regression analysis. RESULTS The nocturnal urine production was 60.6 mL/hr for the total study population; it increased with age and was significantly higher in men with 24-hour polyuria. Nocturnal urine production was on average higher in men with increased nocturnal voiding frequency, but had only a reasonable discriminative value on nocturnal voiding frequency (areas under receiver operating characteristic curve of 0.71 and 0.76). Nocturnal urine production exceeding 90 mL/hr is suggested as abnormal. CONCLUSIONS On average, nocturnal voiding frequency is indicative of nocturnal urine production. However, nocturnal urine production is only a modest discriminator for increased nocturnal voiding frequency. Therefore, the use of nocturnal urine production as an explanatory variable for nocturnal voiding frequency in daily practice is of little value.

Abstract
OBJECTIVE To assess the influence of somatic diseases, symptoms and medication on nocturnal micturition in an elderly population. SUBJECTS AND METHODS All 10 216 members of the pensioners' association in two Swedish counties were asked to participate in a questionnaire survey. The questions concerned their general state of health, occurrence of somatic diseases and symptoms, number of voiding episodes per night, and the use of drugs. RESULTS There were 6143 evaluable questionnaires, of which 39.5% were from men. The mean (sd) age of the men and women participating were 73.0 (6.0) and 72.6 (6.7) years, respectively. In a multivariate logistic model, significant independent correlates of having > or = 3 nocturnal voids (vs < or = 2 voids) were: being 70-79 years vs < 70 years (odds ratio, OR, 1.7, 95% confidence interval, CI, 1.3-2.2), being > or = 80 years old vs < 70 years (OR, 1.9, CI, 1.3-2.5) and poor sleep vs good sleep (OR, 2.6, CI, 2.1-3.2), sequelae after stroke (OR, 2.0, CI, 1.1-3.6), irregular heart beats (OR, 1.6, CI, 1.2-2.1) and diabetes (OR, 1.5, CI, 1.1-2.3). Sex, spasmodic chest pain and snoring were all deleted by the logistic model. CONCLUSION Increasing age, poor sleep, irregular heart beats, diabetes and stroke are associated with an increase in nocturnal micturition in the elderly.

Abstract
OBJECTIVES To review the physiological changes of aging which affect the systems involved in urine formation and to consider how these changes interact with changes in bladder function, thereby leading to the onset of nocturnal polyuria with associated urinary frequency, nocturia, and incontinence. Based on this information, data are presented on the effectiveness of pharmacological interventions which reduce the rate of urine formation and, thus, can be of benefit in reducing symptoms, especially during the nighttime. METHODS Peer-reviewed journal articles were identified by MEDLINE Search and by review of the literature. CONCLUSIONS As a consequence of age-associated diminished renal concentrating capacity, diminished sodium conserving ability, loss of the circadian rhythm of antidiuretic hormone secretion, decreased secretion of renin-angiotensin-aldosterone, and increased secretion of atrial natriuretic hormone, there is an age-related alteration in the circadian rhythm of water excretion leading to increased nighttime urine production in older people. The interaction of nocturnal polyuria with age-related diminution in functional bladder volume and detrusor instability results in the symptoms of urinary frequency, nocturia and, in some persons, incontinence. The additional impact of Alzheimer's disease on these physiological and aging changes, as well as on a diminished perception of bladder fullness, leads to an even greater risk of urinary incontinence in these patients. Treatment of nocturnal polyuria with the antidiuretic hormone analog, DDAVP (desmopressin), can result in decreased nocturnal urine production with improvement in symptoms of frequency, nocturia, and incontinence.

Abstract
Nocturnal polyuria is common in the elderly. In this condition the normal circadian rhythm of urine production is reversed so that urine flow is higher at night than during the day. Elderly men with nocturnal polyuria are commonly referred for prostate surgery, which, not surprisingly, fails to relieve their symptoms. Compared with controls, patients with nocturnal polyuria have higher nocturnal sodium excretion but not higher nocturnal free-water clearance. Similar results have been obtained in children with nocturnal enuresis. Use of vasopressin analogues to induce water retention in elderly patients with nocturnal polyuria is illogical and potentially hazardous; nocturia can be more safely alleviated by diuretic therapy. Nocturnal polyuria in the elderly is associated with hypertension: this is consistent with studies in younger age groups that show that essential hypertension is associated with nocturia and with increased night/day ratios for sodium excretion. We propose that nocturnal polyuria and essential hypertension share some of the same pathophysiological determinants. Specifically, we suggest that a defect in the nitric-oxide pathway may lead to resetting of the pressure-natriuresis relation in the kidney, sodium retention, and compensatory nocturnal natriuresis. This suggestion is consistent with evidence that ageing and essential hypertension are both associated with defects in the nitric-oxide pathway. Our hypothesis has obvious therapeutic implications. More generally, studying the pathogenesis of nocturnal polyuria in the elderly may advance our understanding of the pathogenesis of essential hypertension.
