Purpose: This study was a predicative survey to provide home care clients with indwelling urinary catheters for furnishing basic educational material to their families by analyzing the family members' knowledge, educational needs and educational experience about indwelling catheter management. Method : The subjects consisted of 108 family members who cared for home care clients with indwelling catheters. Data were collected by home care nurses in nine hospitals in Pusan, who directly interviewed with them through questionnaires from Sep. 6th to 30th in 2004. The questionnaires for data collection were developed through pre-survey and reference review. The collected data was analyzed by using frequency, percentile, mean, variation, t-test, ANOVA on SPSS 10.1 package. Results : There were characters of home care clients with indwelling catheters: women(67.6%) were more than men; the average age of them was $69.60{\pm}14.99$ years old; neurogenic and cerebrovascular diseases(80.0%) were the most common disease group; 81.5% of them were totally dependent on others in terms of level of activity. Home care clients' families had these characters: women(76.9%) were more than men; the average age was $54.5{\pm}13.70$ years old; 46.3% of them were parents or sons or daughters in terms of relation with patient; tl1e average care period was $39.8{pm}34.20$ months. Level of knowledge about indwelling catheter management of the family members were 69.8% and its mean were $20.24{\pm}4.53$. Educational needs were 90.9% and its mean were $14.55{\pm}3.56$. Educational experience were 53.3% and its mean were $8.53{\pm}4.30$. 'Complications in using an indwelling catheter', 'Symptoms to call for a home care nurse' and 'Method to attach an indwelling catheter' were high ranked in both educational needs and educational experience. 'Anatomy of urinary tract', 'Functions of urinary tract' and 'Catheter placement' were low ranked in both educational needs and educational experience Level of knowledge about indwelling catheter management of the families showed a significant difference according to their age(F=5.35, p=0.01). Educational needs showed a significant difference according to care period(F=3.06, p=0.04). Conclusion: the family members' level of knowledge and educational experience about indwelling catheter management and their educational were not sufficient while their educational needs were high. In other words although the family members were acknowledged education needs, but the care for the patients with indwelling catheter weren't performed well because of their lack of related knowledge. Therefore systematic educational programs about indwelling catheter management for home care clients and their families should be made on the base of this study.

Purpose : This study assessed the incidence and outcome of congenital anomalies of the kidney and urinary tract (CAKUT) detected by prenatal ultrasonography Methods : There were 906 cases of CAKUT detected by prenatal ultrasonography and postnatally confirmed at the Asan Medical Center from October 1989 to October 2007. We investigated the incidence and outcome of these cases by reviewing medical records retrospectively. Results : The order of incidence was hydronephrosis, multicystic dysplastic kidney (MCDK), duplex kidney, vesico-ureteral reflux (VUR), single kidney, hydroureteronephrosis, ectopic kidney, polycystic kidney, ureterocele, and posterior urethral valve (PUV). There were 520 cases (57.4%) of hydronephrosis, and 20% of these needed an operation due to significant obstruction. MCDK was associated with other CAKUT in 25.4% of all cases. Approximately 57.9% of duplex kidney cases needed surgical treatment due to ureterocele and VUR. VUR had a male: female ratio of 10:1. Two out of seven cases of autosomal recessive polycystic kidney had progressed to chronic renal failure. Patients with PUV were relatively uncommon, and one out of nine cases progressed to end-stage renal disease. Conclusion : CAKUTs detected by prenatal ultrasonography were composed of various anomalies, and almost all of them had a good outcome without any intervention. However, in some cases, recurrent urinary tract infection or renal failure occurred, especially in bilateral cases. For further management, a long-term multicenter study is needed to investigate the precise incidence and outcome of each anomaly in the general population.

Purpose : Urinary tract infection(UTI) is the most common bacterial infectious disease that may induce severe renal injury unless early diagnosis and appropriate treatment are performed. If recurrent UTI is prevented, renal injury can be also reduced. Therefore, we studied the risk factors of recurrent UTI in children. Methods : We performed a retrospective study of 168 children(58 girls and 110 boys) who were treated for UTI in the Department of Pediatrics, Korea University Medical Center, during 2000-2001. Among 168 children, 93 children were followed up for more than six months. For the detection of recurrence of UTI, we performed monthly routine urine cultures and physical examinations. Results : The total rate of recurrence was 32.3%. The recurrent rate in boys and girls were 37.1% and 17.4%, respectively(P<0.05). The most common causative bacteria in the first onset and in recurrence were Escherichia coli. There was a significant difference in the onset age of UTI between boys with recurrence($4.8{\pm}1.0months$) and without recurrence($16.5{\pm}3.8months$)(P<0.01). In 77% of cases, urinary tract infection recurred within six months of the first infection. The time of the first recurrence after UTI was $3.7{\pm}0.6months$ in boys and $14{\pm}8.2months$ in girls(P<0.01). The number of recurrences showed a significant difference between the group under the age of one year($0.69{\pm}0.8/year$) and those above the age of one year($0.16{\pm}0.4/year$)(P<0.05). There was no difference in the recurrent rate between those with structural abnormality and those with normal anatomy. Conclusion : Monthly routine urine cultures are efficient in detecting recurrent UTI in children. Because the male sex and young age especially less than one year of age are risk factors for increased recurrence rate of UTI, these children should be followed-up with urine cultures.

Benign prostatic hyperplasia (BPH) is a highly prevalent, age-related disorder in men which place a considerable burden on health care resources worldwide. While BPH and hypertension are apparently diverse disease processes, they have some features in common(e.g. underlying etiology of the sympathetic nervous system). The purpose of this study is to estimate the prevalence of lower urinary tract symptoms using I-PSS(international prostate symptom score) and to investigate the association of hypertension with I-PSS. This study was carried out to 390 men(40~86 year old) at 3 Myun in Chungju City from July to August, 1997. Subjects answered on questionnaire for I-PSS and were checked age, education, marital status, annual income, blood pressure. The mean age of subjects was 59.8 year old. The mean of I-PSS were increased by age decades(40~49, 50~59, 60~69, 70~86) and it's scores were 4.4, 7.0, 8.2, 12.3 respectively. Strong correlations were observed between the I-PSS and the QUL(quality of life)(P=0.0001). I-PSS(mean-value) were 7.85 in hypertensive group and 8.39 in normotensive group but there was no statistically significance between the two groups(P>0.05). The proportion of mean scoring greater than 8 was 42.5%. There have been reports of association between lower urinary tract symptoms and hypertension, but there was no consistent suggestion that such an association could be casual. The need for high-quality epidemiological information and consequent increased prospects for prevention is obvious.

Primary malignant fibrous histiocytoma (MFH) is a malignant tumor of mesenchymal origin that rarely occurs in the urinary tract, particularly in the urinary bladder. Unlike urothelial carcinoma, which accounts for most bladder cancers, it occurs in the submucosal portion of the bladder wall and consists of the lamina propria, muscularis propria, and adventitia. It is presumed to originate from poorly differentiated pluripotent mesenchymal cells in which fibroblasts and histiocytes are partially differentiated. Radiologically, it is known as the "non-papillary tumor" and is commonly diagnosed as a large mass without necrosis, which shows invasion beyond the muscularis propia. Although the prognosis of this rare malignancy depends on pathological parameters, it generally has a poor prognosis with high local tumor recurrence. Here, we present a case of primary MFH in the urinary bladder with clinical symptoms of lower abdominal pain without gross hematuria that recurred rapidly and showed an aggressive disease course.

Purpose : The current nationally representative data on inpatient care are important to make the of the national public health policy because distributions and the prevalence of diseases among children and adolescents represent the socioeconomic status of the society. The prevalence of chronic disease is increasing now in Korea as the socioeconomic condition is improving. We analyzed a part of genitourinary tract disease of the cross-sectional hospital discharge survey data in Korea collected recently to delineate the trend of genitourinary tract diseases. Methods : Korean nationwide hospital discharge survey for pediatric inpatients in the period from 2004 to 2006 was analyzed. Diagnoses in the data were coded using ICD-10 classification. Totally 826,896 cases were collected from the 85 training hospitals. Selected data of genitourinary tract diseases (belonging to N00-N99 by ICD-10) among 826,896 cases of final inpatients data were analyzed for this study. Results : Among total patients of 826,896, diseases of the genitourinary system accounted for 4.1%. and four diagnostic categories accounted for 92.8%. These were other diseases of the urinary system (N30-39), 45.8%, disease of male genital organs (N40-51),19.1%, glomerular diseases (N00-08), 17.3%, renal tubulo-interstitial diseases (N10-16), 10.6%, respectively. Conclusion : Genitourinary tract disease in pediatric inpatient shows decreasing tendency but the prevalence of chronic diseases is increasing in Korea as the socioeconomic condition is improving. For further comprehensive analysis, regular and organized nationwide survey should be performed. Development of a new data collecting system will improve the performance of such nationwide survey.

Objectives : This study was designed to quantify the characteristics, main diagnosis and complications in the intensive care unit (ICU) at an Oriental Medical Hospital. Methods : The medical records of 44 patients admitted to the ICU at Kyunghee Oriental Medical Hospital between January 1, 2011 and December 31, 2011 were reviewed. Basic characteristics of patients, admission channel, main diagnosis, east-western medical therapy, mortality, and complications were investigated retrospectively based on medical notes. Results : 1. The total number of patients was 44. Males were 63.6%, females 36.3%. Average admission days was 15.9. 2. The most frequent age group is eighties, 38.6%. 3. The most frequent disease is cerebrovascular disease, 61.3%. 4. The medical therapy done after admission to ICU was intubation. Central vein insertion was performed next, followed by Foley's catheter insertion, ventilator, tracheostomy, nasogastric intubation, and thoracentesis in order. The proportion of Oriental medical treatment provided to the patients of ICU was as follows: herbal medication only 6.8%; herbal medication plus acupuncture 31.8%; herbal medication, acupuncture electro-acupuncture, plus subcutaneous acupuncture 2.3%; and none 27.3%. 5. The number of cases of complications occurred since ICU admission was 18. The most frequently observed complication was infection, including 6 cases of pneumonia and 4 cases of urinary tract infection. Conclusions : We suggest that ICUs of Oriental medical hospitals need to be managed effectively to treat diseases including cerebrovascular disease and prevent complications.

Escherichia coli is recovered from a wide variety of infections in many animals species. It may be a primary or secondary agent. Nursing and young animals are particularly susceptible, and urinary tract infections are frequent. The various serotypes of E coli are intestinal inhabitants of animals including humans and probably infect most mammals and birds : therefore, they have a cosmopolitan distribution. Colibacillosis refers to any totalized or systemic infection caused entirely or partly by E coli. Collibacillosis in mammals is most often a primary enteric disease, whereas collibacillosis in poultry is typically a secondary located or systemic disease occurring when host defenses have been impaired or overwhelmed. Other opportunistic bacteria, which can be identified by culture, may play a similar role to that of I coli in secondary infections. Collectively, infections caused by E coli are responsible for significant economic losses to the animal performance. From the standpoint of pathogenic mechanisms and diseases, four major categories of E coli are recognized : enterotoxigenic(ETEC), enteropathogenic (EPEC), enteroinvasive(EIEC), and enterohemorrhagic(EHEC). In addition, two less-well-defined E coli categories are recognized in animals and humans : enteroaggregative and cytotoxin necrotizing factor-positive. The aforementioned categories are represented by different serotypes. Certain serotypes show a host preference and are encountered more frequently in some disease syndromes. Of the four major categories, ETEC is the most common cause of diarrhea in calves, lambs, and pigs. Strains in the other categories cause the less-common diarrhea and other disease syndromes. Enterotoxins and pilus antigens are the two most prominent virulence factors thus far identified for ETEC. Two enterotoxins, one heat-stable(ST) and one heat-labile(LT), are produced by enterotoxigenic strains of E coli : not all culture produce both of these plasmid-based enterotoxins.

Sixty-six dogs diagnosed with cystolithiasis at animal clinics in the Busan area between April 2002, and April 2003, were reviewed. The chemical analysis of cystoliths from 66 dogs indicated that the predominant mineral component was struvite (45 dogs), calcium oxalate (14 dogs), or urate (6 dogs). Animals affected with struvite were grouped into four (s-1; struvite only, s-2; struvite mixed with lesser quantities of calcium oxalate or ammonium urate, s-3; nuclei and lamination, s-4; struvite nucleus surrounded by other minerals), with calcium oxalate into six(o-1; calcium oxalate monohydrate only, o-2; calcium oxalate dihydrate only, o-3; combination of calcium oxalate monohydrate and dihydrate, o-4; calcium oxalate nucleus surrounded by other minerals, o-5; 100% calcium oxalate monohydrate nucleus surrounded by 100% calcium oxalate dihydrate, o-6; mixed calcium oxalate monohydrate nucleus surrounded by mixed calcium oxalate dihydrate), and with urate into two(u-1; ammonium acid urate only, u-2; ammonium acid urate mixed with lesser quantities of other minerals). In this study, the numbers of 4 groups of struvite were (s-1; 10, s-2; 9, s-3; 21, s-4; 5), 6 groups of calcium oxalate were (o-1; 0, o-2; 1, o-3; 2, o-4; 3, o-5; 2, o-6; 6), and 2 groups of urate were (u-1; 6, u-2; 0). The data from each group was analyzed and compared. Shih Tzu(14 cases), Yorkshire terrier(10 cases), mixed-breed(10 cases) and Miniature schnauzer(7 cases) were more frequently affected than the other breeds. Females(40 cases) were affected more than males(26 cases). Twenty-nine dogs had cystoliths associated with a bacterial urinary tract infection, and uroliths tended to recur. We conclude eradication of urinary infection along with appropriate food (e.g. prescription diet) with client compliance should help in reducing the incidence or severity of the disease.
