“…Lastly, estimating bladder capacity, which predicts response to desmopressin, from voiding journals can be difficult and inaccurate. 91 , 92 In one of our unpublished studies, we found children who did not respond or responded partially to desmopressin had smaller cytometric capacity, correlating the findings of other studies. 90 , 92 , 93 Children with smaller bladder capacities were also likely to have overactive bladder (OAB), a condition that clinicians should concurrently treat with anticholinergics.…”

Primary nocturnal enuresis (PNE) is a common childhood disorder that adversely affects a child's mental well-being and social life. Our clinical experience showed parents and their child often have significantly different perspective of enuresis, and these differences can affect family dynamics, treatment approaches, and treatment success. Parents' perception of PNE also influences the likelihood of seeking medical treatment, and we found parents of children with enuresis have markedly different beliefs regarding bedwetting than those of physicians. Because achieving remission for PNE requires parents and their child to actively participate in treatment, assessing their expectancy of success and their beliefs will allow clinicians to adjust treatment goals as necessary. When treating PNE, guidelines consistently recommend incorporating bed alarms as part of the therapy. However, through interviewing parents and treating their children, we found parents preferred medications or other behavioral strategies, such as limiting water intake, because of their convenience. Many parents would complain bed alarms woke them up instead of their child, and they would soon give up on bed alarms. Part of assessing their beliefs includes assessing their confidence in their child being able to wake up to alarms and to persist with treatment. Understanding how they manage and approach setbacks will also determine the treatment modality suited for their child. In this review paper, we detailed our experiences interviewing parents and treating their child with NE with urodynamics and medications at the Changhua Christian Hospital in Taiwan.

“…10 Most voided volumes during the daytime were between 30% and 80% of the MVV. 18 The daytime MVV was significantly less than the overall MVV (179.5 AE 71.1 mL vs. 227.0 AE 79.2 mL, P < 0.001). To avoid confusion, in the current study we separately assessed first morning bladder capacity and daytime MVV (Table 2).…”

Background: This study aimed to evaluate the prevalence of monosymotomatic nocturnal enuresis (MSNE) with reduced bladder capacity in children with primary nocturnal enuresis (NE) and to suggest treatment outcomes. Methods: This study retrospectively evaluated 54 children (30 males, 24 females; median age: 8; range: 5-14) who were newly diagnosed with primary NE from November 2017 to October 2019. Reduced bladder capacity in MSNE was defined when a patient's maximal voided volume (MVV) from his or her voiding diary was 75% or less than estimated functional bladder capacity ([age + 1] x 30 mL) for his or her age and there were no daytime lower urinary tract symptoms (LUTS) as assessed using history taking and questionnaires. Results: Nineteen (35.2%) of 54 children with newly diagnosed primary NE did not report daytime LUTS. Fifteen children (27.8%) had a reduced bladder capacity and were prescribed anticholinergic or beta-3 agonist. After three months of medication, MVV significantly increased from 117.5 mL to 183.3 mL (P = 0.010), but frequency showed no significant change from 5.7 to 4.9 times a day. Improvement in enuresis occurred completely and partially in 41.7% and 25% of participants, respectively. Conclusions: The prevalence of reduced bladder capacity without daytime voiding symptoms was relatively high as 27.8% in children newly diagnosed with primary NE. In primary MSNE, reduced bladder capacity should be investigated using a frequency-volume chart in addition to thorough history taking or questionnaires. Anticholinergics or beta-3 agonists for MSNE with reduced bladder capacity are effective at increasing the bladder capacity of these patients.

“…Lastly, MVV was considered the highest daytime volume. Previous studies have shown that MVV without the first morning voided volume correlates with age ( 29 , 30 ) and more strongly with the EBC as defined by the Hjälmås formula ( 29 ), even though MVV with the first voiding volume included is higher than daytime MVV on the dry nights ( 31 ). MVV, as registered in voiding diaries, may be reliable in MNE ( 32 ) and children with LUTS ( 33 ) compared to volumes measured with other methods (uroflowmetry and cystoscopy).…”

Impact of New vs. Old International Children’s Continence Society Standardization on the Classification of Treatment Naïve Enuresis Children at Screening: The Value of Voiding Diaries and Questionnaires

Expert consensus papers recommend differentiating enuresis using questionnaires and voiding diaries into non- (NMNE) and monosymptomatic enuresis (MNE) is crucial at intake to decide the most appropriate workout and treatment. This national, Belgian, prospective study investigates the correlation, consistency, and added value of the two methods, the new against the old International Children’s Continence Society (ICCS) definitions, and documents the prevalence of the two enuresis subtypes in our population. Ninety treatment-naïve enuretic children were evaluated with the questionnaire, and the voiding diary and the two clinical management tools were compared. Almost 30% of the children had a different diagnosis with each method, and we observed inconsistencies between them in registering Lower Tract Symptoms (κ = –0.057–0.432 depending on the symptom). Both methods had a high correlation in identifying MNE (rs = 0.612, p = 0.001) but not for NMNE (rs = 0.127, p = 0.248). According to the latest ICCS definitions, the incidence of MNE was significantly lower (7 vs. 48%) with the old standardization.ConclusionThe voiding diary and the questionnaire, as recommended by the ICCS at the screening of treatment-naïve enuretic patients, are considerably inconsistent and have significantly different sensitivities in identifying LUTS and thus differentiating MNE from NMNE. However, the high incidence of LUTS and very low prevalence of MNE suggest that differentiating MNE from NMNE to the maximum might not always correlate with different therapy responses.
