Polyuria is occasionally observed after general anesthesia with sevoflurane. Usually the onset of polyuria is abrupt and remission is spontaneous, so it's not so easy to do detailed investigation. The authors came across with two cases of polyuria during general anesthesia with sevoflurane which occurred so early around one hour after induction of anesthesia. Both cases revealed no special problem like central diabetes insipidus.

We report three cases of Diabetes insipidus which charactrized by the polyuria and polydipsia. All of the three cases well controlled with oral addministration of chlorpropamide. Two cases were idiopathic and the other was suspected pituitary tumor. A briet review of literature was made.

A patient with beta hCG-secreting germ cell carcinoma of the pineal and suprasellar regions presented with hydrocephalus, Parinaud's syndrome, hypopituitarism and polyuria. Central diabetes insipidus was strongly suspected although the water deprivation test was not diagnostic. The polyuria however, responded to ADH analogue when the hypothyroidism and hypocortisolism were treated. Pubertal development was evident and serum testosterone was normal despite the low FSH/LH, suggesting hCG stimulation of Leydig cells. This case illustrates that a beta hCG-germ cell tumour of the suprasellar region causing hypopituitarism can mask the presence of central diabetes insipidus and hypogonadotrophic hypogonadism.

PURPOSE: We tried to discover the normal voiding pattern, which was diurnal & nocturnal urinary volume, voiding frequencies in healthy older men without prostate disease. MATERIALS AND METHODS: All voided volumes, times and frequencies were recorded for 3 days in 158 healthy men without any voiding problems. The subjects ages ranged from 31 to 49 for 47 men (mean age 42.8), 50 to 59 for 38 men (mean age 54.1), 60 to 69 for 39 men (mean age 67.3), 70 to 81 for 34 men (mean age 74.5). The subjects age related changes in bladder capacity, urinary volume and frequency were evaluated. The causes of nocturnal urinary frequency and its increase with age in healthy older men were evaluated using 3 days of voiding diaries. Nocturia was devided into three types: nocturnal polyuria, decreased nocturnal bladder capacity and mixed type. RESULTS: Nocturnal bladder capacity, functional bladder capacity, total urinary voiding volume and daytime urinary voiding volume decreased with age. Nocturnal urinary frequency increased with age. Nocturnal urinary volume did not change with age. 76 (48%) of the 158 volunteers had 2 or more voidings per night. 9 (12%) of the 76 volunteers had nocturnal polyuria. 39 (51%) had decreased nocturnal bladder capacity, and 28 (37%) had mixed type. CONCLUSIONS: Normal voiding patterns changed with age, especially in subjects over 60 years. In most cases, nocturia was caused by decreased nocturnal bladder capacity, since nocturnal urinary volume did not change with age but nocturnal bladder capacity decreased with age.

PURPOSE: The aim of this study, to investigate whether there is any association between enuresis in childhood and nocturnal polyuria syndrome (NPS) in adult life. METHODS: The study consisted of thirty five patients with nocturnal polyuria, and thirty five healthy people without nocturnal polyuria in adult life, were asked to assess their enuresis in childhood. RESULTS: There was a history of enuresis in childhood in 18 (51.42%) of 35 of men with nocturnal polyuria and in 4 (11.42%) of 35 without nocturnal polyuria. Enuresis in childhood was significantly more common in men with nocturnal polyuria than without nocturnal polyuria. The difference was significant (P<0.0001). The prevalence of enuresis in the nocturnal polyuria (51.42%) was more than two-fold higher than reported prevalence in general populations. CONCLUSIONS: The results of this study suggest that the history of enuresis in childhood seems to increase the risk of having NPS in adult life. This relationship should be taken into account in the evaluation of men with complaints from NPS in adult life and the possible common pathophysiology should be considered in the treatment planning.

Polyuria is occasionally observed during general anesthesia. Usually urine output during general anesthesia is decreased because of anesthetic agents. The authors came across with a case of polyruia during sevoflurane anesthesia which occurred after induction of anesthesia. Polyuria is a nonspecific symptom, but can cause many serious complications. Therefore, it is very important to investigate the cause thoroughly and treat patient appropriately.

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.

PURPOSE: We tried to discover the voiding patterns, which was diurnal & nocturnal urinary volume and voiding frequencies in women with overactive bladder (OAB). MATERIALS AND METHODS: All voided volumes, times and frequencies were recorded in 249 women with overactive bladder. The subjects age related changes in bladder capacity, urinary volume and frequency were evaluated. The causes of nocturnal urinary frequency and its increase with age in older women with OAB were evaluated using 3 days of voiding diaries. Nocturia was devided into three types: nocturnal polyuria, decreased nocturnal bladder capacity and mixed type. RESULTS: Total voided volume, daytime urine volume, functional bladder capacity were decreased with the age. Nocturnal urine volume and nocturnal urinary frequency were increased with age. Nocturnal polyuria was the major cause for nocturia, and mixed type was increased with age. CONCLUSIONS: Voiding symptoms as well as storage symptoms were increased with age in OAB female. In most cases, nocturia was caused by nocturnal polyuria.

Nocturnal polyuria is one of the main pathogenic mechanisms of enuresis. Disturbance of circadian rhythm of antidiuretic hormone (ADH or AVP), hypercalciuria, and/or solute diuresis are considered to cause nocturnal polyuria, which in turn causes enuresis in patients with relatively small bladder capacity and high threshold for awakening. Evaluation of these factors would guide the therapeutic approach for enuresis.

PURPOSE: Nocturia, from which the patients feel the most discomfort, is one of the frequently complained urologic symptoms combined with insomnia. Studying the etiology and classification of nocturia is not enough. In this study, we analyzed the voiding diary and urodynamic study to investigate the etiology of nocturia. We classified the type of nocturia based on the etiology. MATERIALS AND METHODS: We reviewed the urodynamic study (UDS) as well as the three days voiding diary of 152 patients with nocturia. We classified nocturia into three groups based on the voiding diaries and the results of UDS: Pure nocturnal polyuria in which the voided urine volume during the hours of sleep is more than 35% of the 24-hours urine volume, detrusor overactivity defined as existing uninhibited contraction on filling cystometrogram, and mixed (nocturnal polyuria with detrusor overactivity). Polyuria (24-hours urine output >2,500cc) was classified separately. RESULTS: The mean number of nocturia was 3.3 (3.1 for men, 3.4 for women). octurnal polyuria, detrusor overactivity and mixed were 50.0%, 7.9% and 17.1% respectively. Nocturnal polyuria was not related with detrusor overactivity, bladder outlet obstruction and impaired detrusor contractility, but significantly increased with age (p<0.01) and in men (p<0.05). Detrusor overactivity was not related to impaired detrusor contractility, but was significantly related to the bladder outlet obstruction (p<0.05) and increased with age (p<0.01) and in men (p<0.01). Seventeen (11.2%) had polyuria. CONCLUSIONS: In 75% of nocturia patients, there were nocturnal polyuria, detrusor overactivity or mixed type and 11.2% of them had polyuria. Therefore we conclude that these three causes were the main etiology of nocturia, and nocturia could be classified and treated based on these results.
