Nocturnal enuresis is a heterogeneous disorder with various underlying pathophysiological mechanisms and causes a mismatch between the nocturnal bladder capacity and the amount of urine produced during sleep at night. It is associated with a simultaneous failure of conscious arousal in response to the sensation of bladder fullness. Generally, a complete history and physical examination, with a specific focus on the genitourinary, gastrointestinal, and neurologic systems, is sufficient to evaluate a patient with enuresis. The therapeutic focus is directed toward a differential approach based on the underlying mechanism and toward combination therapies such as alarm devices and desmopressin as well as anticholinergic agents and desmopressin. Children with increased nocturnal urine production usually have a good response to desmopressin therapy. Patients with a small bladder generally show a poor response to desmopressin treatment, but they would benefit more from combination therapy with enuretic alarm, urotherapy, and antimuscarinic agents in addition to desmopressin. Different types of bladder dysfunction, which result in a small nocturnal bladder capacity, probably contribute significantly to the pathogenesis of nocturnal enuresis, particularly in those with treatment failure and refractory symptoms. Because different clinical subgroups may show different responses to treatment, it is necessary to distinguish these subgroups before a decision on the specific treatment protocol can be made.

Purpose: Recently, the conception and cognition that enuresis was resolved spontaneously, have changed. We reviewed the attitudes of the primary care physicians who make diagnose and treat nocturnal enuresis. Methods: From January 2006 to February 2007, a total of 293 primary care physicians in Daegu city participated in this survey. Questionnaires included questions about physicians' opinions on the appropriated age for diagnosis of enuresis, the likely causes of enuresis, etc. Physicians are grouped in two according to whether enuresis is major field of their subspecialty; the pediatrician & urologist group and the other physician group. Results: 59.2% of pediatricians and urologists thought that enuresis is defined as the nightly involuntary release of urine by children of the age of 5 to 6, while 49.6% of other physicians did. For the causes of enuresis, most of clinicians checked "yes" to the question that "Under-developed bladder and nerve" and "Emotional problems". In the patient's behavioral reactions related to enuresis, "Lack of concentration in home and school" and "Frequent urination" were most responded. Attendance to the education program of enuresis in last five years and willing to participate in education program was statistically different among pediatricians-urologists and other physicians. Regarding the treatment of enuresis, most physicians used imiprarnin widely, but pediatricians and urologists preferred desmopressin. Alarm was the last one in treatment modality. Conclusion: This study revealed that pediatricians and urologists are attending more to the educational places and knowing much about the recent information on enuresis when compared to other primary care physicians, regarding the diagnostic age and treatment modality of enuresis. The education of enuresis for primary physicians is more needed.

Purpose : The purpose of this study was to investigate the prevalence of enuresis in association with voiding habits and socioeconomic status in elementary school children. Methods : A dynamic survey was done of 1,514 students from two elementary schools in Suwon, Korea in December 2006. Data regarding gender, age, height and weight, voiding habits, and monthly family incomes were gathered and analyzed to discover any correlation with the incidence of enuresis. The percentile value of height or weight was extrapolated from the standard population curve. Results : Among 1,514 children, 1,063 (70.2%) answered and returned the questionnaires. Overall, the prevalence of enuresis was 8.7% and there was no difference between the public (8.8%) and private school (8.7%). The family incomes of the students from the two schools differed greatly from each other, but there was no difference in the prevalence of enuresis between the two schools. Children with a habit of void-holding showed a higher prevalence of enuresis. No significant correlation was found between the prevalence of enuresis and the height and weight percentile of children. Experience with hospital visits was low among enuretic children (20.8%), suggesting that Korean parents tend to neglect treatment of enuresis for their children. The prevalence of enuresis decreased by 2.0% each year, as school children aged. Conclusion : The overall prevalence of enuresis among elementary school children in Suwon district was 8.7%. The 12.1% prevalence of enuresis at the seven years came down gradually, to be nil at the age of 13. Infrequent urination or void-holding was assumed to be one of the important factors causing enuresis in elementary school children.

Hinman syndrome is a condition representing urinary voiding dysfunction in the neurologically intact child. The syndrome is probably caused by acquired behavioral and psychosocial disorders manifested by bladder and/or bowel dysfunction mimicking neurologic disease. Clinically, the symptom complex may include day and night time enuresis, encopresis, constipation, and recurrent urinary tract infections. Cystoscopy frequently demonstrates normal vesicourethral anatomy. Voiding films usually demonstarate a carrot-shaped proximal urethra with a persistent narrowing at the external sphincter. The bladder is large and often appears trabeculated with a thickened wall and significant postvoid residual. A 13-year-old male child was admitted due to fever, urinary tract infection, enuresis and flank pain. His neurologic examination was normal. Renal sonograms showed moderate hydronephrosis. Voiding cystourethrograms showed a huge, trabeculated bladder without vesicourethral reflux and urethral valves. No abnormal findings was found in spinal MRI.

Objectives The purpose of this study is to evaluate the efficacy and safety of herbal medication for the treatment of nocturnal enuresis in children by analyzing randomized controlled trials conducted in China. Methods We searched literatures from China National Knowledge Infrastructure published up to 19 January, 2018. Selected literatures were collected and analyzed in order of publication year, and then demographic information, treatment method, duration of illness, duration of treatment, follow-up period, outcome measurement and adverse events. Results A total of 34 studies were selected for the analysis. In most studies, the total efficacy of the treatment group was reported to be higher than that of the control group, and the recurrence rate and complete cure rate were also found to be more effective in the herbal medicine treatment group. The most frequently used medical herb was Alpiniae Fructus (益智仁), and the use of medical herbs belong to tonifying yang (補陽藥), tonifying qi (補氣藥), and astringing essence strengthening collapse medicine (澁精縮尿止帶藥) were relatively high. The adverse events rate for the herbal medicine treatment group were significantly lower than those in the Western medicine treatment group. Conclusions This study showed that a herbal medicine treatment can be effective and safe option for treating pediatric nocturnal enuresis. However, additional well-designed clinical studies need to be performed to establish a basis.

Purpose : Hypercalciuria has been suggested to be involved in the pathogenesis of nocturnal enuresis associated with polyuria. We have measured the amount of calcium excretion in the urine from children with monosymptomatic nocturnal enuresis and studied the association with enuresis. Methods : Thirty-six children (20 males and 16 females, age 5 to 15.6 years) presenting with monosymptomatic nocturnal enuresis were recruited for this study. Results : Among 36 patients, 6 patients had hypercalciuria, providing a 16.7% frequency. The mean Ca/Cr ratio of hypercalciuria group showed $0.23{\pm}0.10$ on daytime, and $0.33{\pm}0.10$ on nighttime showing higher values in nighttime, but it was not statistically significant. Average 24 hour calcium excretion was 8.95 mg/kg. Night/day time urine volume ratio in hypercalciuria group was $0.87{\pm}0.20$, and that in normocalciuria group was $0.81{\pm}0.33$, also showing no difference. Daytime Ca/Cr ratio and nighttime Ca/Cr ratio from all enuresis patients showed a significant correlation (P=0.0001). However, Ca/Cr ratio between daytime and nighttime urine volume had no significant correlation, respectively (daytime P=0.08; nighttime P=0.07). Also, daytime and nighttime Na concentration, urea concentration, and osmolality also had no significant correlation with urine Ca/Cr ratio, respectively. Conclusion: Hypercalciuria shown in some of enuresis patients is not directly caused by primary monosymptomatic nocturnal enuresis.

Purpose: Nocturnal enuresis (NE) is one of the most common problems in childhood. NE has a multifactorial etiology and is influenced by sleep and arousal mechanisms. The aim of the present study was to prospectively evaluate sleep problems and patterns in children with NE compared with normal healthy controls. Methods: Twenty-eight children with NE and 16 healthy controls were included in the study. To evaluate sleep habits and disturbances, parents and children filled out a questionnaire that included items about sleep patterns and sleep-related behaviors prior to treatment for NE. Demographic factors and other data were compared for the two groups based on the responses to the sleep questionnaire. Results: Night awakening, sleepwalking, and periodic limb movements were more prevalent in children with NE, but symptoms of sleep-disordered breathing were not increased in this group. There were statistically significant differences in periodic limb movements and daytime sleepiness between the two groups. Conclusion: Children with NE seemed to have more sleep problems such as night awakening, sleepwalking, and periodic limb movements. In addition, a higher level of daytime sleepiness and hyperactivity in patients with NE suggested a relationship between NE and sleep disorders.

Purpose: The ability to concentrate urine becomes an important index in determining nocturnal enuresis (NE) treatment. The aim of our study was to investigate first-morning urine osmolality (Uosm) changes at the end of treatment compared to before treatment in children with NE. Methods: A total of 71 children with NE were divided into two groups according to the level of first-morning Uosm before treatment: high group (≥800 mOsm/kg) and low group (<800 mOsm/kg). Baseline parameters were obtained from uroflowmetry, frequency volume charts for at least 2 days, and a questionnaire for lower urinary tract symptoms. All patients were basically treated with standard urotherapy and medication. The first-morning Uosm was measured twice, before treatment and at the end of treatment. Results: The response rate was higher in the low group after 3 months of treatment than in the high group (P=0.041). However, there was no difference between the two groups at the end of the treatment. In the high group, the first-morning Uosm at the end of treatment did not show a significant change compared to before treatment. In contrast, the first-morning Uosm increased in the low group at the end of treatment (P<0.001). However, it was still lower than that of the high group (P=0.007). Conclusions: The ability to concentrate nocturnal urine improved at the end of treatment compared to before treatment in the low Uosm NE children. In addition, NE improved faster in the low Uosm group before treatment than in the high group.
