PURPOSE The impact of the original International Childrens Continence Society terminology document on lower urinary tract function resulted in the global establishment of uniformity and clarity in the characterization of lower urinary tract function and dysfunction in children across multiple health care disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric lower urinary tract function. MATERIALS AND METHODS A variety of worldwide experts from multiple disciplines in the ICCS leadership who care for children with lower urinary tract dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. In addition, contributions and feedback from the multidisciplinary ICCS membership were solicited. RESULTS Following a review of the literature during the last 7 years the ICCS experts assembled a new terminology document reflecting the current understanding of bladder function and lower urinary tract dysfunction in children using resources from the literature review, expert opinion and ICCS member feedback. CONCLUSIONS The present ICCS terminology document provides a current and consensus update to the evolving terminology and understanding of lower urinary tract function in children.

PURPOSE This article is one of the standardization documents of the International Childrens Continence Society, and discusses how anatomical/iatrogenic and functional/urodynamic causes of daytime incontinence in children of all ages are to be diagnosed, how neurogenic bladder dysfunction or urinary tract infection is excluded as a cause of the wetting, and how further diagnostic evaluation of children with disturbances such as overactive bladder, voiding postponement and dysfunctional voiding is performed. The roles of history taking (including prenatal and perinatal issues and family history), physical examination, diagnostic bladder diaries, noninvasive urodynamic investigations and radiological imaging are delineated but therapy is not within the scope of this document. MATERIALS AND METHODS This document was designed and written by an international panel of authors with a large experience in assessment of children with incontinence. RESULTS The best evidence was retrieved from the literature and assembled in a standardization document. CONCLUSIONS Assessment of children with daytime symptoms is discussed. A noninvasive approach in these children allows us to select patients who will need a more invasive assessment.

OBJECTIVE Recently, a cross-cultural continence-specific paediatric quality-of-life measurement tool (PinQ) has been developed and tested psychometrically. The aim of this study was to evaluate the test re-test reliability of this new tool in a cohort of children with bladder dysfunction in order to evaluate the reproducibility of scores. A secondary aim was to compare the parent-completed proxy version with child-reported scores. METHODS PinQ was translated and back-translated from English into Chinese and Dutch and scrutinized for cultural and linguistic appropriateness or ambiguity. Forty children aged 6-15 years from both countries were asked to self-complete the measure at first consultation and then again 14 days later. No new treatment was implemented between data collection points. On the initial visit, parents also completed a proxy version of PinQ. Intraclass correlations (one-way random effects model) were used to analyze the data. RESULTS The intraclass correlation coefficient (ICC) for comparison between items and factors showed little variability in scoring. One item was not reproducible and was removed from the tool. Overall proxy scores varied little from the child-reported scores. However, the impact on the child of his/her parents concern about the bladder problem was poorly perceived (ICC=0.18) as was the impact on the childs sense of self-worth (0.17). CONCLUSION PinQ has been shown to be reliable under test re-test conditions when completed by children from the age of 6 years. Proxy PinQ suggests that parents accurately evaluate the effect of bladder dysfunction on wellbeing in their children. A 20-item measurement tool will now be introduced clinically and subjected to sensitivity testing for treatment outcome and diagnostic grouping.

AIMS To date there have not been any generic or continence-specific measurement tools that allow clinicians to investigate quality of life in children with bladder dysfunction. The aim of this research was to create a cross-cultural tool to assess and measure the wider psychosocial impact of current and new interventions for bladder dysfunction in children. MATERIALS AND METHODS The study was conducted in three parts: expert consultation with continence clinicians; design and administration of a child-completed international questionnaire; item analysis, validity and reliability testing, and design of a new tool. RESULTS The need for a pediatric incontinence QoL measure evaluation was strongly endorsed by clinicians. Data from 156 child-completed questionnaires collected in 10 countries was analyzed for item characteristics and found to be free of item correlation and ceiling and floor effects. Factor analysis revealed 2 factors, which were labeled intrinsic and extrinsic. Rasch analyses showed the internal validity of both subscales was reasonable good. Cronbachs alpha for each factor was 0.91 and 0.72. After analysis, items were selected for the new tool, PinQ, and evaluated for ambiguity, clarity, comprehension level required, choice of words and phrases, and age-appropriate concepts. Twenty-one items were finally selected and randomly positioned within the tool. CONCLUSIONS A cross-cultural tool that quantifies the holistic effect of bladder dysfunction in children has been designed and tested for validity.

PURPOSE We identified the profile of lower urinary tract changes in ketamine users in the community. In addition, we identified the relative risks of dose, frequency of ingestion and duration of ketamine use for changes in lower urinary tract function. MATERIALS AND METHODS A mobile medical assessment service was established at specific youth centers, and subjects who were known to social workers and who had a history of ketamine use were invited to participate in health screening. Lower urinary tract function was evaluated using the Pelvic Pain, Urgency and Frequency questionnaire, and uroflowmetry and ultrasonography. RESULTS Use of ketamine more than 3 times weekly was significantly associated with lower voided volumes. Pelvic Pain, Urgency and Frequency questionnaire scores were significantly higher for ketamine use for more than 24 months compared to use for short durations (7.82 vs 6.00). The scores on the symptom and bother subscales of the Pelvic Pain, Urgency and Frequency questionnaire decreased progressively with increased duration of abstinence. For individuals after 1 year of abstinence the Pelvic Pain, Urgency and Frequency questionnaire scores were significantly lower and voided volumes were higher than those for active users. CONCLUSIONS Ketamine users with at least a 2-year habit of 3 or more hits per week have altered bladder function that can be recognized and that causes bother. These early functional changes have the potential to normalize after 1 year of ketamine abstinence. This study provides a basis for the development of health promotion material that can be used in the community by welfare workers seeking to encourage drug cessation.

BACKGROUND It is known that cardiac surgical patients with diabetes have greater peri-operative mortality and morbidity when compared with nondiabetic patients; the rate of adverse events in other surgery subspecialties has been only investigated minimally. The aim of this study was to test the magnitude of association between overt diabetes mellitus and postoperative complications across a spectrum of noncardiac surgical patients. METHODS Prospective outcome data registries describing 1,343 data sets from a spectrum of surgical subspecialties were examined to establish the prevalence of diagnosed diabetes, the incidence of intra- and postoperative complications, and the difference in proportion of morbidity between diabetic versus nondiabetic patients. RESULTS There was a significant difference in overall morbidity between diabetic and nondiabetic patients with a 2.0 and 1.6 times increased morbidity risk in known diabetic patients with and without malignancy, respectively. Known diabetes was related to the number of postoperative complications in noncardiovascular patients. CONCLUSION This study quantified the association between known diabetes and the occurrence of complications during recovery after a spectrum of noncardiac surgery. Because of a high prevalence of prediabetic and undiagnosed conditions, the strength of associations between glucose dysregulation and operative outcomes may be even greater than we report.

BACKGROUND Intraoperative hyperglycemia in cardiac and neurosurgical patients is significantly associated with morbidity. Little is known about the perioperative glycemic profile or its impact in other surgical populations or in nondiabetic patients. METHODS A systematic review of blood glucose values during major general surgical procedures reported since 1980 was conducted. Data extracted included blood glucose measures, study sample size, gender distribution, age grouping, study purpose, surgical procedure, anesthetic details, and infusion regime. Excluded studies were those with subjects with diabetes insipidus, insulin-treated diabetes, renal or hepatic failure, adrenal gland tumors or dysfunction, pregnancy, and emergency or trauma surgery. RESULTS Blood glucose levels rose significantly with the induction of anesthesia (P < .001) in nondiabetic patients. At incision, 2 hours, 4 hours, and 6 hours, 30%, 40%, 38%, and 40% of studies, respectively, reported hyperglycemia. CONCLUSIONS Factors that confound or protect against significant rises in perioperative glycemic levels in nondiabetic patients were identified. The findings facilitate investigating the impact of hyperglycemia on general surgical outcomes.

OBJECTIVE Patient satisfaction is an important indicator of healthcare system performance. High patient satisfaction is associated with greater trust in caregivers, improved compliance with treatment recommendations and a better quality of life (QOL). There are few validated instruments to measure surgical patients satisfaction. The aim of this study was to develop a culturally-specific patient satisfaction instrument, for use as an outcome measure in evaluating surgical services. DESIGN Patient focus groups were convened to explore dimensions of the peri operative hospital experience. Forums uncovered pertinent domains of interest and identified terminology understood by patients. A preliminary set of items reflecting patient satisfaction was developed. Test-retest reliability of a new surgical patient satisfaction instrument was assessed in 42 subjects at hospital discharge. RESULTS Domains that emerged included; admission processes and hospital environment, information provision, nursing care, doctor and nurse interaction, and ancillary staff services. Staff attitudes and human qualities were highly valued, as was prompt attention to requests for assistance. Clarity or quality of medical information did not appear to influence in-patient satisfaction. A new measure of surgical patient satisfaction, Hong Kong Index of Inpatient Happiness (HK2Happ), was developed from focus group consultation. Test-retest generated an Intra Class Correlation of 0.868-0.935, indicating a highly stable tool. CONCLUSION The initial version of HK2Happ was reliable in assessing surgical patient satisfaction. The measure is now undergoing validity testing across different surgical patient populations for generalization and generation of a short form of discriminant items.
