To evaluate published evidence on nocturia in men and derive expert recommendations. The International Consultations on Urological Diseases-Société Internationale d'Urologie convened a Consultation of experts on male lower urinary tract symptoms. The Consultation assigned standardized levels of evidence and grades of recommendation to various studies of nocturia epidemiology, pathophysiology, assessment, and treatment. Evidence review and consensus recommendations were made in the areas of epidemiology, pathophysiology, assessment, and treatment. The review presents a condensed summary of the International Consultations on Urological Diseases-Société Internationale d'Urologie evaluation of nocturia, which offers contemporaneous expert consensus on this topic, with an assessment algorithm emphasizing the potential contribution of systemic conditions to the symptom.

Lower urinary tract symptoms are numerous, but the specific impact of each of these symptoms on the quality of life (QoL) has not been evaluated in community-dwelling men. An assessment of these symptoms and their effects on QoL was the focus of this study. We performed a cross-sectional study with 373 men aged >50 years from a community setting. Patients completed the International Prostate Symptom Score questionnaire, which includes questions on each of the specific urinary symptoms and a question addressing health-related QoL that are graded from 0 to 5. We used the Pearson correlation test to assess the impact of each symptom on QoL. Nocturia (58.9%) was the most prevalent urinary symptom. The mean score was 0.9±1.4 for incomplete emptying, 1.0±1.5 for frequency, 0.9±1.3 for intermittency, 0.8±1.3 for urgency, 1.0±1.5 for weak stream, 0.5±1.0 for straining, and 2.0±1.6 for nocturia. Nocturia and frequency were the only symptoms associated with poorer QoL, with nocturia showin...
Luts-V: A New Simplified Score for Assessing Lower Urinary Tract Symptoms in Men
2020
OBJECTIVE: To validate a new simplified score for the assessment of men with LUTS (LUTS-V). METHODS: We made adjustments to the VPSS, resulting in a new simplified instrument (LUTS visual score - LUTS-V). In a pilot study, LUTS-V was administered to 50 men to identify interpretation issues. We used the International Prostate Symptom Score (IPSS) as the gold standard to validate the new tool in 306 men. The total IPSS and LUTS-V scores for each subject were evaluated and we used Bland-Altman analysis and Pearson's correlation plot to assess the agreement between the scores. A ROC curve was utilized to determine the diagnostic accuracy of LUTS-V and its diagnostic properties were described in terms of sensitivity, specificity, positive, and negative predictive values. RESULTS: Median age was 59 [52-67] years and, according to the IPSS, 26 (8.7%) patients had severe symptoms, while 99 (33%) had moderate symptoms, and 175 (58.3%) had mild symptoms. We found a positive correlation be...
The association between the ICIQ-LUTS and the ICIQ-bladder diary in assessing LUTS
OBJECTIVES: The bladder diary (BD) provides a non-invasive method of investigating lower urinary tract symptoms (LUTS) while the International Consultation on Incontinence Questionnaires (ICIQ) symptom questionnaires, such as the ICIQ-MLUTS and ICIQ-FLUTS for males and females, respectively, provide a subjective assessment. The association between objective and subjective assessments has not been well established for the ICIQ. MATERIALS AND METHODS: Retrospective analysis of data collected from a urodynamics database was conducted. Only patients who completed both the ICIQ-MLUTS/FLUTS and the ICIQ-BD were included. Assessment of the relationship between the ICIQ-BD and the ICIQ-MLUTS/FLUTS with regards to daytime frequency and nocturia episodes was conducted using descriptive statistics to determine how well they correlate. RESULTS: A total of 3054 patients were on the database with only 529 patients fully completing both the ICIQ-BD and ICIQ-MLUTS/FLUTS from February 2012 until November 2014. Criterion testing showed fair agreement between the nocturia question on the ICIQ-MLUTS/FLUTS and the ICIQ-BD (Kappa = 0.339; P < 0.001; 48.5%). Whereas diary recordings of daytime voiding frequency showed low agreement with questionnaire responses (Kappa = 0.254; P < 0.001; 42.7%). The degree of agreement was higher at lower frequencies. Females had a slightly higher agreement than males during the daytime (43.2% vs 41.6%) and nighttime (49.3% vs 47%). CONCLUSION: The ICIQ-BD is a simple, cheap, valid, and reliable method to assess LUTS in everyday clinical practice. However, an agreement between the ICIQ-BD and the ICIQ-MLUTS/FLUTS with regards to daytime frequency and nocturia episode is weak and therefore both are needed in the assessment of patients with LUTS.
Mechanisms and grading of nocturia: Results from a multicenter prospective study
2020
Objective: To identify pathophysiological mechanisms of nocturia and the correlation of these mechanisms with nocturia severity. Methodology: After approval by the local ethics committee, all patients with nocturia ([?]1 nocturnal void/night) were included and filled the overactive bladder questionnaire (OABq), nocturia quality of life (N-QoL), ICIQ-MLUTS (male), ICIQ-FLUTS (female) and 3-day frequency-volume chart. Patients were divided into three groups according the severity of nocturia: group 1 consisted of patients with mild (1-2 voids/night), group 2 with moderate (3-4 voids/night) and group 3 with severe nocturia (>4 voids/night). Comparative analysis were performed between groups, p<0.05 was deemed as statistically significant. Results: 68.1%, 64.1% and 8.7% of the patients had nocturnal polyuria, reduced bladder capacity and global polyuria; respectively. 42.7% of the patients had mixed nocturia. 6.1% of the patients did not comply with the afore-mentioned subtypes and defined as isolated nocturia. Regarding the severity of nocturia; 155 (41%) patients had mild, 167 (45%) patients had moderate and 57 (15%) patients had severe nocturia. Increased nocturia severity was related with decreased quality of life; higher age, urinary tract symptom scores, nocturnal urine volume, evening fluid consumption and beta-blocker medication rates. Increased nocturia severity was also associated with higher nocturnal polyuria, global polyuria and reduced bladder capacity rates. Conclusions: Nocturia mechanisms may vary between mild and moderate to severe nocturia groups according to the present study. Nocturia grading with identification of subtypes may help for better standardization of the diagnostic and treatment approaches as well as for the design of future clinical trials.

The International Prostate Symptom Score (IPSS) is a useful tool approved by the World Health Organisation and the American Urological Association to measure the severity of lower urinary tract symptoms (LUTS). Although commonly used in urological practice, the IPSS has faced many challenges in terms of its usage in developing countries. In our setting, most patients presenting with this condition are elderly patients with a low literacy level. Given this background, the IPSS could be time consuming and difficult to administer to such patients and it may lead to additional costs to the services. The objective of this study was to compare the accuracy of a Single Question Nocturia Score (SQNS) with the IPSS in evaluation of lower urinary tracts symptoms in men with Benign prostatic hyperplasia(BPH). The study was designed as a cross-sectional study using researcher-administered IPSS and SQNS questionnaires. The sensitivity, specificity, and correlation coefficient were used to compar...
