Abstract
Ultrasonography (US) is an essential tool in the clinical management of lower urinary tract dysfunction (LUTD), including lower urinary tract symptoms, overactive bladder, and benign prostatic hyperplasia, in which prostatic volume and post-void residual volume are routinely used to evaluate the pathophysiological characteristics of afflicted patients. US can also be employed to diagnose hydronephrosis and bladder calculus as complications of severe LUTD. Moreover, US is essential for identifying pathophysiological characteristics and surgical indications, predicting disease development and drug efficacy, and monitoring bladder function improvement by means of such parameters as bladder wall thickness, prostatic urethral length, intravesical prostatic protrusion, and prostatic urethral angulation/angle. Herein, I narratively review the recent advances in US approaches for the management of LUTD, especially in adult males.

Rasmussen VF, Thrysøe M, Karlsson P, Madsen M, Vestergaard ET, Nyengaard JR, Terkelsen AJ, Kamperis K, Kristensen K. Bladder dysfunction in adolescents with type 1 diabetes. J Pediatr Urol 2024; 20:564.e1-564.e9. [PMID: 38705761 DOI: 10.1016/j.jpurol.2024.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 02/26/2024] [Accepted: 04/09/2024] [Indexed: 05/07/2024]
Abstract
BACKGROUND It is increasingly significant that adults with diabetes experience lower urinary tract symptoms, however, there has been limited research in younger individuals with type 1 diabetes. OBJECTIVE To investigate bladder function using non-invasive urodynamics as a potential indicator of autonomic neuropathy in adolescents with type 1 diabetes. This involved examining the association between urinary flow disturbances, reported symptoms, and results from other autonomic tests. STUDY DESIGN Cross-sectional study enrolling 49 adolescents with type 1 diabetes and 18 control subjects. All participants underwent uroflowmetry and ultrasound scanning, completed the Composite Autonomic Symptom Score (COMPASS)-31 questionnaire, and were instructed to record their morning urine volume and voiding frequencies and report them back. Cardiovascular reflex tests (CARTs) and the quantitative sudomotor axon reflex test (QSART) were performed. RESULTS The main results are shown in the Summary figure. DISCUSSION In this study, urological abnormalities were not significantly more frequent in adolescents with diabetes, however, urological issues were observed. This is supported by previous findings of Szabo et al. who found that adolescents with type 1 diabetes had reduced flow acceleration and time to maximum flow compared to control subjects. In our study, we observed cases with reduced acceleration and prolonged uroflow curves, possibly indicating detrusor underactivity. People with diabetes had a higher risk of nocturia than healthy controls, which our results supported. Some adolescents reported urination twice per night. Based on these findings, it is considered beneficial to ask about urological symptoms annually to determine if more examinations (frequency-volume charts and uroflowmetry) are necessary and/or if any opportunities for treatment optimization exist. However, uroflowmetry has limitations, as bladder filling and emptying is a complex process involving multiple pathways and neurological centers, making it difficult to standardize and evaluate. Another limitation of this study was that our control group was smaller and consisted of fewer males than females, which could affect the results due to differences in anatomy and physiology in the lower urinary tract system. CONCLUSION In conclusion, adolescents with type 1 diabetes, as well as healthy adolescents, frequently experience urological symptoms. Although urological abnormalities were not significantly more frequent in adolescents with diabetes in this study, the focus on nocturia and risk for bladder dysfunction seems relevant, even in adolescents without any other tests indicating autonomic dysfunction.

Evidence-based clinical practice guideline for management of urinary tract infection and primary vesicoureteric reflux. Pediatr Nephrol 2024; 39:1639-1668. [PMID: 37897526 DOI: 10.1007/s00467-023-06173-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/27/2023] [Accepted: 09/17/2023] [Indexed: 10/30/2023]
Abstract
We present updated, evidence-based clinical practice guidelines from the Indian Society of Pediatric Nephrology (ISPN) for the management of urinary tract infection (UTI) and primary vesicoureteric reflux (VUR) in children. These guidelines conform to international standards; Institute of Medicine and AGREE checklists were used to ensure transparency, rigor, and thoroughness in the guideline development. In view of the robust methodology, these guidelines are applicable globally for the management of UTI and VUR. Seventeen recommendations and 18 clinical practice points have been formulated. Some of the key recommendations and practice points are as follows. Urine culture with > 104 colony forming units/mL is considered significant for the diagnosis of UTI in an infant if the clinical suspicion is strong. Urine leukocyte esterase and nitrite can be used as an alternative screening test to urine microscopy in a child with suspected UTI. Acute pyelonephritis can be treated with oral antibiotics in a non-toxic infant for 7-10 days. An acute-phase DMSA scan is not recommended in the evaluation of UTI. Micturating cystourethrography (MCU) is indicated in children with recurrent UTI, abnormal kidney ultrasound, and in patients below 2 years of age with non-E. coli UTI. Dimercaptosuccinic acid scan (DMSA scan) is indicated only in children with recurrent UTI and high-grade (3-5) VUR. Antibiotic prophylaxis is not indicated in children with a normal urinary tract after UTI. Prophylaxis is recommended to prevent UTI in children with bladder bowel dysfunction (BBD) and those with high-grade VUR. In children with VUR, prophylaxis should be stopped if the child is toilet trained, free of BBD, and has not had a UTI in the last 1 year. Surgical intervention in high-grade VUR can be considered for parental preference over antibiotic prophylaxis or in children developing recurrent breakthrough febrile UTIs on antibiotic prophylaxis.

Abstract
OBJECTIVE To establish a normal reference value of postvoid residual (PVR) urine volume in "healthy" adults. METHODS Adults were recruited to undergo uroflowmetry and PVR. Those with neurological disorders, malignancy, diabetes, known lower urinary tract dysfunction, and urinary tract infection within the previous 3 months, were excluded from the study. Constipation was defined as Rome IV ≥ 2. RESULTS Of the 883 adults enrolled in this study, 194 (22.3%) did not complete the questionnaires or perform the uroflowmetry, 103 (11.7%) met ≥1 exclusion criteria and thus were excluded. In addition, 30 and 38 uroflowmetry were excluded due to artifacts and low bladder volume (BV) (<100 mL), respectively. Finally, 515 uroflowmetry and PVR data from adults aged 36-89 (mean: 59.0 ± 9.5) were examined. There was a significant nonlinear relationship between BV and PVR (p < 0.05), with PVR significantly increased when BV was around 528 mL. Women had lower PVR than men (p < 0.05). PVR also increased as the International Prostatic Symptom Score (IPSS) increased. PVR was unaffected by age and functional constipation. A multivariate analysis revealed that BV (p < 0.05) and IPSS (p < 0.05) had significant influence on PVR, but age, gender, and Rome IV score did not. The 90th and 95th percentiles of PVR for men were 73.2 mL (25% of BV) and 102.6 mL (30% of BV), respectively, while for women they were 60.5 mL (21% of BV) and 93.8 mL (27% of BV), respectively. CONCLUSION Women had lower PVR than men. The 90th percentile or 95th percentile of normal adults' PVR may serve as the upper limit of normal PVR, and readings above this level may necessitate additional evaluation and treatment. Further studies are required to substantiate these recommendations.

Abstract
Ultrasound imaging is a less invasive imaging modality without radiation exposure and is available for repeated tests. It is the gold standard examination for diagnosing and managing disorders of the urinary tract, including lower urinary tract dysfunction (LUTD) in pediatric urology. Ultrasound imaging is effective for screening underlying diseases and determining treatment strategies. Ultrasound examination at the bedside should focus on post-voided residual urine (PVR), bladder wall thickening, renal morphology, and rectal diameter. Since PVR must be tested immediately after voiding, examining infants who cannot complain of the urge to void is difficult. PVR measurement combined with a 4-h voiding observation or alarm system activated by urine is recommended for these infants. Early diagnosis is important because LUTD is associated with the risk of morbid residual urine and high voiding pressure, which can result in renal deterioration, urinary leakage, and febrile urinary tract infection.

Comparative Effectiveness of Two Models of Point-of-Care Ultrasound for Detection of Post-Void Residual Urine during Acute Ischemic Stroke: Preliminary Findings of Real-World Clinical Application. Diagnostics (Basel) 2023; 13:2599. [PMID: 37568961 PMCID: PMC10417127 DOI: 10.3390/diagnostics13152599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 07/31/2023] [Accepted: 08/01/2023] [Indexed: 08/13/2023] Open
Abstract
We conducted a comparative study of two models of point-of-care ultrasound devices for measuring post-void residual urine (PVRU). We prospectively enrolled 55 stroke inpatients who underwent both real-time B-mode ultrasound (Device A) and automated three-dimensional (3D) scanning ultrasound (Device B), with a total of 108 measurements. The median PVRU volume of Device B was 40 mL larger than that of Device A. The PVRU difference between the devices was positively and linearly correlated with PVRU. The correlation of PVRU volume between the devices was strong, but the agreement level was only moderate. Measurement deviations were observed in 43 (40%) and 11 (10%) measurements with Device B and Device A, respectively. The PVRU volume was low in spherical bladder shapes but sequentially increased in triangular, undefined, ellipsoid, and cuboid bladder shapes. Further comparison of 60 sets of PVRU without measurement deviations revealed higher agreements between the devices at correction coefficients of 0.52, 0.66, and 0.81 for PVRU volumes of <100, 100-200, and >200 mL, respectively. The automated 3D scanning ultrasound is more convenient for learning and scanning, but it exhibits larger measurement deviations. Real-time B-mode ultrasound accurately visualizes the urinary bladder but tends to underestimate the urinary bladder when the PVRU volume is large. Hence, real-time B-mode ultrasound with automated PVRU-based adjustment of calculation formulas may be a better solution for estimating bladder volume.

A prospective cohort study of assisted bladder emptying following primary cloacal repair: The Children's National experience. J Pediatr Urol 2023; 19:371.e1-371.e11. [PMID: 37037763 DOI: 10.1016/j.jpurol.2023.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 02/20/2023] [Accepted: 03/11/2023] [Indexed: 04/12/2023]
Abstract
INTRODUCTION/BACKGROUND Although the combination of bladder dysfunction and upper tract anomalies puts patient with cloaca at risk for renal disease, the rarity of this condition makes it difficult to study empirically. As a high-volume center, we uniquely capture bladder function outcomes following our growing number of cloacal repairs. OBJECTIVE 1) Describe the rates of incomplete bladder emptying following primary cloacal repair (at 2-3 months after repair and last follow up), and 2) identify clinical factors associated with assisted bladder emptying. STUDY DESIGN We performed a prospective cohort study of patients undergoing primary cloaca repair by our Children's National Colorectal Center team between 2020 and 2021. The primary outcome was assisted bladder emptying at 2-3 months postoperatively and last visit. Covariables included preoperative characteristics (cloacagram measurements), ARM complexity (moderate = common channel [CC] <3-cm, severe = CC ≥ 3-cm), vesicoureteral reflux (VUR) status, sacral ratio (good ≥0.7, intermediate 0.7-0.4, poor ≤0.4), spinal cord status, means of preoperative bladder emptying, and operative details (age at repair, repair type, & concomitant laparotomy). RESULTS Eighteen participants were eligible. A majority had moderate cloaca (78%), VUR (67%), spinal cord abnormalities (89%), and good sacral ratios (56%). Preoperatively, 10 patients were diapered for urine and 8 had assisted bladder emptying. Surgical repairs were performed at a median age of 8 months (range 4-46). Nine (50%) patients underwent urogenital separation (UGS), eight (44%) total urogenital mobilization, and 1 (6%) perineal sparing posterior sagittal anorectoplasty with introitoplasty. Exploratory laparotomy was performed in 7 (39%) patients. At 2-3 months, 7 patients were voiding and 11 required assisted bladder emptying. Median length of long-term follow up was 12 months (range 5-25), and 8 patients were voiding and 10 required assisted bladder emptying. Postoperative need for assisted bladder emptying was significantly associated with assisted bladder emptying preoperatively, a shorter urethra and increasing common channel length, UGS and exploratory laparotomy. Spinal cord imaging findings were not associated. DISCUSSION Bladder emptying following cloaca repair is likely a result of congenital function and surgical effects. Indeed, increasingly cloaca complexity requiring UGS and laparotomy was associated with both pre- and post-operative assisted bladder emptying. The lack of association with spinal cord imaging may reflect a divergence between anatomy and function. CONCLUSION Approximately half of patients required assisted bladder emptying in this study. Associated factors included urethral and common channel length, the need for assisted bladder emptying preoperatively, the type of surgical approach and additional laparotomy. Being diapered with seemingly normal voiding prior to surgery did not guarantee normal bladder function postoperatively.

Abstract
INTRODUCTION Elevated post void residual (PVR) is a significant risk factor for urinary tract infections (UTI). It is also a significant predictor of treatment outcomes in cases of vesicoureteral reflux, pediatric enuresis, and non-neurogenic LUT dysfunction. However, the absence of age-specific nomograms for adolescents may limit PVR's use in clinical practice. OBJECTIVE To establish age- and gender-specific normal PVR urine volume in adolescents. MATERIAL AND METHODS Healthy adolescents aged 12-18 years were recruited to undergo two uroflowmetry and PVR studies whenever they felt the urge to urinate. Adolescents with neurological disorders, known LUT dysfunction or UTI were excluded. RESULTS A total of 1050 adolescents were invited, but only 651 consented. Fourteen participants were excluded due to low bladder volume (BV < 100 ml) in both assessments (n = 12), BV < 100 ml in one assessment (n = 1), or failure to provide relevant history (n = 1). From the 1084 uroflowmetry and PVR obtained from 637 adolescents, 190 results were further excluded due to artefacts (n = 152), BV < 100 ml (n = 27), PVR >100 ml (n = 5) and missing information (n = 6). Ultimately, 894 uroflowmetry and PVR from 605 adolescents (mean age 14.6 ± 1.5 years) were analyzed. PVRs were higher in adolescents aged 15-18 years than in those aged 12-14 years (P < 0.001). Moreover, they were higher in females than in males (P < 0.001). Multivariate analysis revealed that PVR was positively influenced by age (P = 0.001) and BV (P < 0.001). The age- and gender-specific percentiles of PVR in ml and percentage of BV were calculated. We recommend a repeat PVR and close monitoring if PVR is above the 90th percentile, i.e., PVR >20 ml (7% BV) for males of both the age groups, and PVR >25 ml (9% BV) and PVR >35 ml (>10% BV) for females aged 12-14 and 15-18 years, respectively. Further investigation may be warranted if the repeat PVR is above the 95th percentile, i.e., PVR >30 ml (8% BV) and >30 ml (11% BV) for males aged 12-14 and 15-18 years, respectively, and PVR >35 ml (11% BV) and >45 ml (13% BV) for females aged 12-14 and 15-18 years, respectively. CONCLUSION PVR increases with age and varies by gender; thus, age-and gender-specific reference values should be used. Further data from other countries is required to determine whether the study's recommendations can be applied globally.

Abstract
AIMS To establish normal reference values of urine flow acceleration (Qacc ) in healthy children, as there is a lack of nomograms for normative reference values of Qacc by voided volumes in the pediatric population so far. Qacc might be an early indicator of autonomic neuropathy in children and adolescents. METHODS Data were retrospectively collected from healthy children who underwent uroflowmetry between 1990 and 1992. Exclusion criteria were voided volume less than 20 ml, and postvoid residual more than 15%. Baseline characteristics and uroflowmetry parameters were collected from girls and boys aged between 6 and 18 years. Voided volume, voiding time, time to maximum flow rate, and maximum and average flow rates of urine were measured, and Qacc was calculated. Postvoid bladder diameter was measured by ultrasonography and converted to volume. RESULTS Uroflowmetry parameters of 208 children (≤18 years old, 45.2% girls, mean age 9.68 ± 3.09 years) who performed 404 micturition were analyzed. Median voided volume, voiding time, time to Qmax , Qave , Qmax , Qacc , and postvoid residual volume were 130 [20-460] ml, 10 [3-56] s, 3 [1-14] s, 11.7 [2.5-36.6] ml/s, 20.5 [5-50] ml/s, 6 [0.81-25] ml/s2 , and 1.83 [0-38.62] ml, respectively. Qacc nomograms were given in centile forms for girls and boys separately, which show an inversely proportional correlation between voided volumes. CONCLUSIONS These are the first nomograms for normative reference values of Qacc in the pediatric population (girls and boys separately) by voided volumes in centile forms. These may be useful to interpret abnormal Qacc values and diagnose lower urinary tract diseases over a wide range of voided volumes.

Effectiveness of a voiding evaluation technique using a diaper equipped with a urination-activated alarm system to assess bladder function and voiding patterns in infants. J Med Ultrason (2001) 2022; 49:695-701. [PMID: 35999417 DOI: 10.1007/s10396-022-01251-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 07/20/2022] [Indexed: 10/15/2022]
Abstract
PURPOSE Four-hour voiding observation is a conventional method for evaluating bladder function in infants. However, it requires a diaper check every 5 min during the observation period, which creates an unusual environment for the infant, making the evaluation of natural urination difficult. This study aimed to investigate the parameters of urination before mature bladder function using a diaper equipped with a urination-activated alarm system. METHODS The study participants were 51 infants aged 0-4 years without bladder dysfunction. A urination-activated sensor was used to notify the inspector wirelessly when urination was detected, enabling the immediate assessment of ultrasonically measured residual urine. Bladder capacity was calculated as the sum of both residual urine volume and micturition volume, and the residual urine rate as the residual urine volume divided by bladder capacity. RESULTS A total of 36 boys and 15 girls were enrolled. The median (interquartile range) residual urine volume, bladder capacity, and residual urine rate were 3.0 mL (1.1-6.6), 53.0 mL (33.9-75.3), and 7.0% (2.1-15.0), respectively. Infants aged 0-1 and 2-4 years were then classified into Group A (N = 27) and Group B (N = 24), respectively. The residual urine rate was significantly higher in Group A (11.0% [5.4-21.2]) than in Group B (4.8% [0.6-8.9]; p < 0.01). CONCLUSIONS Voiding observation using a urination-activated alarm system allowed less invasive analysis in infants and revealed that the residual urine rate decreased with mature bladder function from about 2 years of age.

Can portable ultrasound bladder scanner be applied to young children less than three years old? J Pediatr Urol 2022; 18:344-349. [PMID: 35221250 DOI: 10.1016/j.jpurol.2022.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 01/21/2022] [Accepted: 02/02/2022] [Indexed: 11/21/2022]
Abstract
INTRODUCTION The bladder scanner (BS), a portable ultrasound device specialized in bladder volume measurement, has been developed and applied to clinical assessment of postvoid residual urine, which is a requisite in evaluating patients with voiding dysfunction. However, experiences in the application of the BS to the pediatric population remain limited despite commonly encountered reluctance to catheterization. This prospective observational study aimed to evaluate the correlation and accuracy of the newly developed pediatric module of the BS (BioCon-900) in measuring bladder volume in children 0-6 years old. MATERIALS AND METHODS This study included 29 patients scheduled to undergo preventive untethering for their spinal dysraphism. When they undergo cystometry for the confirmation of normal neurologic function, bladder volume was measured by BS when recorded volume infusion reached each quartile of the age-adjusted estimated bladder capacity (EBC). The difference (bias) between measured and infused volume was expressed as a percentage of EBC (%EBC). The correlation coefficient and the Bland-Altman plot were obtained to determine the discriminating power and accuracy, respectively. The acceptable limit was set as 30%EBC. RESULTS A strong correlation between the measured and infused volume (r = 0.95, P < 0.001) was found for the entire age range. This excellent correlation remained comparable between children less than three years and the older ones. Bladder volume tended to be overestimated, and the mean bias was 33 ± 22.3%EBC, and it became higher with increasing quartiles. The accuracy was acceptable in all ranges of measurement in the older group and first and second quartiles in the younger one. DISCUSSION We have first evaluated the potential use of BS in 0-3 years old children and compared the results with 4-6-year-old children in whom the accuracy of BS has been demonstrated. The strong point of our study was the inclusion of data spanning all quartiles of bladder volume. The use of infused volume as reference enabled us to assess the accuracy in a more precise way than the use of ultrasound. Despite the good discriminating power, the accuracy was not acceptable in higher quartiles in the younger group. If the trend of overestimation especially higher volume, could be understood prior to measurement, it would be helpful to assume the real val. CONCLUSIONS The children's module in BS showed excellent discriminating power and generally acceptable accuracy in more than four-year-old children. This may lose accuracy in higher quartiles among less than three years old children.

Abstract
OBJECTIVES We aimed to investigate the changes in urodynamics and voiding cystourethrogram parameters on pre- and post-untethering surgery in patients aged under 2 years with filum lipoma. METHODS Sixty-two patients were enrolled in this study. The changes in urodynamics and voiding cystourethrogram parameters were compared before untethering surgery and 6 months after untethering surgery. These parameters were bladder volume, bladder deformity, vesicoureteral reflux during voiding cystourethrogram, detrusor overactivity, bladder compliance, and post-void residual volume in urodynamics. RESULTS Bladder volume during voiding cystourethrogram and bladder compliance increased significantly from 89.8 ± 49.5 mL to 114.5 ± 50.5 mL (P = 0.0069) and 10.2 ± 6.2 mL/mmH2 O to 17.0 ± 13.3 mL/mmH2 O (P = 0.0008), respectively, at 6-month follow-up. Six patients required combination management with clean intermittent catheterization at 25.1 ± 8.2 months (14.3 ± 6.5-months follow-up) because of elevated post-void residual volumes. CONCLUSIONS According to voiding cystourethrogram results, bladder function and urodynamics in patients with filum lipoma significantly improved after untethering surgery. Non-invasive assessment based on measurements of post-void residual should be considered as a postoperative follow-up method.

Abstract
AIM To evaluate lower urinary tract symptoms (LUTS) in children with infantile-onset Pompe disease (IOPD) who received early treatment. METHODS Pompe disease (PD), or glycogen storage disease II is a rare autosomal recessive lysosomal storage disease that affects multiple organ systems. To our knowledge, only one study has focused on the relationship between LUTS and incontinence in children with PD. This cross-sectional study was conducted from August 2019 through March 2021 and children with IOPD, who had received early and regular enzyme replacement therapy, were enrolled. Participants or their parents completed the Dysfunctional Voiding Scoring System (DVSS) questionnaire. All children underwent uroflowmetry and postvoid residual urine measurements. Fourteen children (age, 4-9 years) with IOPD were enrolled. RESULTS Ten patients (71.4%) had abnormal uroflow curves. In addition, results of the DVSS revealed that approximately half (42.9%) of our IOPD patients had voiding dysfunction, with urinary incontinence as the most common symptom (64.3%, 9/14). No significant correlations were found between LUTS and uroflow curves in children with IOPD. CONCLUSIONS The frequency of LUTS and lower urinary tract dysfunction noted on uroflowmetry should encourage pediatricians to actively identify IOPD patients with LUTS, regardless of the timing and frequency of their treatments, and refer them to a urologist for further evaluation and appropriate treatment.

Abstract
To investigate the urodynamic study (UDS) result in pediatric patients suffering from spastic cerebral palsy (CP). Medical records of patients diagnosed CP having pre-operative UDS results underwent selective dorsal rhizotomy (SDR) from Jan. 2020 to May. 2021 were retrospectively reviewed. Fifty-seven cases diagnosed spastic CP were included in the study (mean age, 6.73 ± 2.84 years), among which, 46 were ambulatory and 11 non-ambulatory. Average gross motor function measure-66 (GMFM-66) score was 62.16 ± 11.39. Reduced bladder capacity was seen in 49.12% of these cases and cases with lower GMFM-66 score possessed a higher incidence rate of having low bladder capacity (p < 0.01). Detrusor overactivity (DO) was shown in 33.33% of the patients. Cases with younger age presented a higher prevalence of DO (p < 0.05). Meanwhile, more non-ambulant patients suffered from DO (p < 0.05). Increased post-voiding residual (PVR) was seen in 21.05% of the cases. Those with higher average threshold in sphincter-associated input spinal nerve roots (rootlets) witnessed a higher rate of having abnormal PVR (p < 0.05). Abnormal UDS results were prevalent in pediatric patients suffering from CP. Motor function, age and threshold of their sphincter-associated spinal nerve roots laid corresponding effect on the abnormal UDS results.

Abstract
The followings are the level of evidence (LE) and grade of recommendation (GR) on pediatric UTI in Asia. Classification according to the sites of infection (lower versus upper tract), the number of episode (first versus recurrent), the severity (simple versus severe), or the existence of complicating factor (uncomplicated versus complicated) is useful to differentiate children with UTI whether they are at risk of renal damage or not (LE: 2, GR: B). Diagnosis of UTI requires both urinalysis that suggests infection and positive urine culture (LE:3, GR B). For pre-toilet trained children, urine specimen for culture should be collected by urethral catheterization or suprapubic aspiration. For toilet trained children, midstream clean catch urine is reliable (LE: 3, GR: A). Urine culture is considered positive if it demonstrates growth of a single bacterium with the following colony counts: (1) any growth by suprapubic aspiration, (2) >5 × 104 CFU/ml by urethral catheterization, or (3) >105 CFU/ml by midstream clean catch (LE:3, GR: B). For children with febrile UTI, renal and bladder ultrasonography (RBUS) should be routinely performed as soon as possible (LE: 3, GR: C). RBUS should be followed up 6 months later in children with acute pyelonephritis and/or VUR (LE: 3, GR: C). Acute DMSA scan can be performed when severe acute pyelonephritis or congenital hypodysplasia is noted on RBUS or when the diagnosis of UTI is in doubt by the clinical presentation (LE: 3, GR: C). Late DMSA scan (>6 months after the febrile UTI) can be performed in children with severe acute pyelonephritis, high-grade VUR, recurrent febrile UTIs, or abnormal renal parenchyma on the follow-up RBUS (LE: 3, GR: C). Top-down or bottom-up approach for febrile UTI is suggested for the diagnosis of VUR. For top-down approach, VCUG should not be performed routinely for children after the first febrile UTI. VCUG is indicated when abnormalities are apparent on either RBUS or DMSA scan or both (LE: 2, GR: B). VCUG is also suggested after a repeat febrile UTI (LE:2, GR: B). Appropriate antibiotic should be given immediately after urine specimen for culture has been obtained (LE:2, GR: A). Initiating therapy with oral or parenteral antibiotics is equally efficacious for children (>3 months) with uncomplicated UTI (LE: 2: GR: A). The choice of empirical antibiotic agents is guided by the expected pathogen and the local resistance patterns (LE: 2, GR: A). For children with febrile UTI, the total course of antibiotic therapy should be 7-14 days (LE: 2, GR: B). Circumcision may, but not definitively, reduce the risk of febrile UTI in males and breakthrough febrile UTI in males with VUR. Circumcision should be offered to uncircumcised boys with febrile UTI and VUR in countries where circumcision is accepted by the general population (LE: 3, GR: B), while in countries where childhood circumcision is rarely performed, other measures for febrile UTI/VUR should be the preferred choice (LE: 4, GR: C). Bladder bowel dysfunction (BBD) is one of the key factors of progression of renal scarring (LE: 2). Early recognition and management of BBD are important in prevention of UTI recurrence (LE:2, GR: A). Antibiotic prophylaxis to prevent recurrent febrile UTI is indicated in children with moderate to high grade (III-V) VUR (LE: 1b, GR: A). Surgical intervention may be used to treat VUR in the setting of recurrent febrile UTI because it has been shown to decrease the incidence of recurrent pyelonephritis (LE: 2, GR: B).

Non-invasive bladder function measures in healthy, asymptomatic female children and adolescents: A systematic review and meta-analysis. J Pediatr Urol 2021; 17:452-462.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) are common in children and adolescents. Non-invasive tests evaluating bladder function are generally preferred over invasive tests, yet few studies have explored the range of normative values for these tests in healthy, asymptomatic children. OBJECTIVE To define normative reference ranges for non-invasive tests of bladder function in healthy, asymptomatic girls and adolescents. STUDY DESIGN A comprehensive search strategy was performed in seven electronic databases through October 2019. English-language studies reporting data on voiding frequency, voided and postvoid residual volumes (PVR) and uroflowmetry results in healthy, asymptomatic girls (mean age ≥ 5 years) were included. Two independent reviewers performed study review, data extraction, and quality assessment. Overall mean estimates and 95% confidence intervals for each bladder function parameter were calculated using random effects models, and 95% normative reference values were estimated. RESULTS Ten studies met eligibility criteria for the meta-analysis (n = 2143 girls, age range: 3-18). Mean estimates of maximum voided volume and PVR were 233.4 ml (95% CI 204.3-262.6; n = 1 study) and 8.6 ml (95% CI 4.8-12.4; n = 2 studies) respectively. Pooled mean estimates for uroflowmetry parameters were: 21.5 ml/s (95% CI 20.5-2.5) for maximum flow rate (n = 6 studies), 12.5 ml/s (95% CI 11.2-13.8) for mean flow rate (n = 6 studies), 6.8 s (95% CI 4.4-9.3) for time to maximum flow (n = 3 studies), 15.7 s (95% CI 13.0-18.5) for flow time (n = 3 studies), and 198.7 ml (95% CI 154.2-234.2) for voided volume (n = 9 studies). No studies reported estimates of voiding frequency. Between-study heterogeneity was high (89.0-99.6%). CONCLUSIONS Although we were able to calculate pooled mean estimates for several parameters, the small number of included studies and the wide age ranges of participants preclude generalization of reference values to all healthy girls. Further research is needed to determine normative reference values within specific age groups.

Time until maximum flow rate uroflowmetry: A new parameter for predicting failure of transcutaneous electrical nerve stimulation (TENS) in treating children and adolescents with overactive bladder. J Pediatr Urol 2021; 17:472.e1-472.e5. [PMID: 34229976 DOI: 10.1016/j.jpurol.2021.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 03/28/2021] [Accepted: 05/09/2021] [Indexed: 11/20/2022]
Abstract
AIM To analyze uroflowmetry as a predictor of the outcome of treatment with parasacral transcutaneous electrical nerve stimulation (TENS) in patients with pure overactive bladder. METHODS Thirty-eight patients of 5-16 years of age were included in this prospective cohort study. All the patients had been seen at a referral clinic between 2006 and 2015. All had a diagnosis of pure overactive bladder and were treated with TENS. Parameters established at pretreatment uroflowmetry were evaluated, with patients then being separated into two groups based on their visual analogue scale (VAS) score immediately following TENS. The variables analyzed at uroflowmetry were: maximum flow rate, curve pattern (bell or tower-shaped), time until maximum flow and voided volume. RESULTS The mean age of the children evaluated was 7.26 years (SD: 2.62) (95%CI: 6.4-8.13) and 73.7% were girls. No association was found between maximum flow rate, curve pattern (bell or tower-shaped) or voided volume and the complete resolution of symptoms following treatment. Nevertheless, a shorter time until maximum flow was associated with a greater likelihood of treatment failure. CONCLUSION The time until maximum flow rate before treatment is a potential predictor of the outcome of TENS treatment.

Abstract
PURPOSE Association of spinal or vertebral anomalies and the iatrogenic denervation during surgical correction of anorectal malformation patients especially in boys can lead to neurogenic bladder inthese subset of patients. The paucity of literature with regard to urodynamic studies focusing exclusively in male children with high-anorectal malformations (HARM) lead us to analyze the urodynamic changes. The objective was to study urodynamic profile in male patients who have undergone surgery for anorectal malformation. METHODS Male high-anorectal malformation patients who had completed all the stages of repair were prospective studied. Following the basic work up, all patients based on the urodynamics were categorized into 2 groups as safe or unsafe bladders. Unsafe bladder was defined as detrusor pressure > 40 cm (high detrusor pressure) or pressure variability of 15 cm of water (detrusor overactivity) or significant post-void residue. MRI was limited to patients with only abnormal urodynamics to rule out spinal causes of neurogenic bladder and due to financial constraints, it could not be offered to all patients. RESULTS 41 HARM meet the exclusion criteria. All patients were asymptomatic with none having history of urinary tract infections. Ultrasound showed bladder wall thickening in 31.7% patients. UDS revealed reduction in bladder capacity and compliance was noted in 31.7% and 30% patients, respectively. Elevated detrusor pressures (> 40 cm of water) were noted in 10% (4/41), detrusor overactivity with concomitant elevated detrusor pressures in 19.5% (8/41) and normal UDS in 70% (29/41). 13 patients (31.7%) had abnormal cystometric parameters with 12(30%) having unsafe bladders. MRI confirmed sacral agenesis in 1 patient with unsafe bladder. CONCLUSION Urodynamics can demonstrate occult neurovesical dysfunction in patients with HARM. This would help in early renal protective therapy and prevent the burden of long-term sequelae of neurovesical dysfunction in HARM patients.

[PMID: 33137854 DOI: 10.1111/luts.12363] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 10/15/2020] [Accepted: 10/19/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVES Lower urinary tract symptoms (LUTS), particularly urgency, incontinence and intermittency are common in children and it is suggested that the specific symptoms may be used for definite diagnosis for LUT dysfunction (LUTD). This study was performed to investigate the relationship between each LUTD and its associated symptoms, using uroflowmetry/electromyography (UF/EMG) as a diagnostic tool. METHODS Each patient was categorized into one of four LUT conditions which were overactive bladder (OAB), dysfunctional voiding (DV), underactive bladder and primary bladder neck dysfunction (PBND), according to UF/EMG results. Patients' complaints and findings were documented by using voiding dysfunction symptom score, bladder diary, urine analysis and ultrasonography. In addition, a detailed history of bowel habits (including use of Rome III criteria) was obtained. RESULTS There were 189 children of which 106 were female. The OAB was the largest group including 91 patients, followed by the DV group which had 61 patients. The symptoms specific to any LUTD group were constipation and hesitancy (P < .05). Hesitancy was present in 89.4% with PBND and constipation was present in 78.6% of patients with DV. None of other symptoms were able to differentiate any LUTD group from the other. CONCLUSIONS While certain symptoms are often presumed by clinicians to imply specific diagnoses, the main outcome of this study is that there is a generally weak correlation between the specificity of symptoms and LUTD. Symptoms-based approach may lead to misdiagnosis in LUTD. Thus, it may be essential to focus on the underlying pathologies and UF/EMG test may help this.

Abstract
OBJECTIVES To evaluate the relationship between residual urine volume, pyuria and bladder carcinoma recurrence. METHODS The clinical data of 305 patients who had post-void residual urine volume measured and preoperative pyuria were retrospectively collected. The patients were classified into three risk groups based on the presence of residual urine and pyuria: good (negative residual urine and pyuria), intermediate (positive residual urine or pyuria) and poor (positive residual urine and pyuria). Predictive factors for intravesical recurrence-free survival were statistically analyzed using Cox proportional hazard models and Kaplan-Meier methods. The propensity score matching method was used to adjust the patients' backgrounds. RESULTS The median follow-up period for all patients was 44 months. The presence of residual urine (P = 0.0164) and pyuria (P = 0.0233) were two independent prognostic factors for recurrence. After patients were classified into risk groups, the poor-risk group showed significantly shorter recurrence-free survival compared with that of the good- (P = 0.0002) and intermediate-risk groups (P = 0.0090). Even after matching, the presence of residual urine was related to short recurrence-free survival in male patients (P = 0.0012). When stratified by European Organization for Research and Treatment of Cancer risk groups, the presence of pyuria was related to short recurrence-free survival, especially for intermediate-risk patients without bacillus Calmette-Guérin treatment. CONCLUSIONS Post-void residual urine and preoperative pyuria are two risks for recurrence-free survival in non-muscle-invasive bladder cancer.

Abstract
Much is still unknown about LUT function after receiving renal graft. Graft function was the main focus of different studies discussing the same issue. However, these studies ignored the effects of the graft on lower tract function and more demand for bladder cycling and growth of the child. Therefore, we aimed at evaluating the LUT function after RT into patients with LUTD. We enrolled a retrospective cohort of 83 live renal transplant children with LUTD. The 44 patients in Group (A) had a defunctionalized bladder, and the 39 patients in Group (B) had underlying LUT pathology. All patients had clinical and urodynamic evaluation of LUT functions at least 1 year after RT. We found that the improvement in patients with impaired bladder compliance was 73% in Group (A) and 60% in Group (B), with no statistically significant difference between the study groups. In Group (B), there was statistically significant worsening of MFP (8.4%) and mean PVR (79.9%) after RT. In Group (A), mild but stable significant improvement of all clinical and urodynamic parameters was observed. Serum creatinine was significantly worse in patients with pathological LUTD compared with those with defunctionalized bladder but without significant effect on graft survival. All LUT variables seemed to have no adverse effect on graft survival except for use of CIC and augmented bladder. Incident UTI independent of LUT variables accounted for 20% of graft creatinine change.

Abstract
OBJECTIVE To evaluate the efficacy of the screening protocol and the clinical follow-up to detect urological anomalies (UA) in patients with ARM (ARM-P) in our institution. Secondary aim was to define the prevalence of UA and their relationship with severity of ARM. METHODS ARM-P were selected from a prospectively maintained database from 2000 to 2016. Exclusion criteria were: incomplete or with less than 3 years of follow-up and absence of surgical correction of the anorectal anomalies. Data from urological screening and follow-up were collected. Patients were divided into complex malformations (Group 1) and less complex malformations (Group 2). RESULTS One hundred seventeen of 149 were included in the study period (62 group 1, 55 group 2). UA were detected in 36/117 at birth (30.7%) with a difference between groups (P = .0005). VUR was detected in 16 (6 with hydronephrosis, 10 with normal ultrasound at birth). A bladder ultrasound after potty training showed 18 lower urinary tract dysfunction (LUTD; 15 with UA detected at birth, 3 with normal ultrasound). 8 LUTD were found during clinical follow-up, confirmed by ultrasound. Spinal MRI detected spinal cord anomalies (SCA) in 52/117 (44.4%). Considering the subgroups with neurogenic bladder and SCA there was a difference between groups (13/33 vs 1/19). CONCLUSION This study suggests that ARM-P are at increased risk of UA, most of which were detected on neonatal ultrasound. While screening protocol can show 88% of UA, follow-up can detect 12.9 % of total abnormalities without difference between groups. This data has to be considered when planning follow-up for these patients.

Abstract
To describe how to perform urological evaluation in children with tethered cord syndrome (TCS). Although a common manifestation of TCS is the development of neurogenic bladder in developing children, neurosurgeons often face difficulty in detecting urological problems in patients with TCS. From a urological perspective, diagnosis of TCS in developing children is further complicated due to the differentiation between neurogenic bladder dysfunctions and transient bladder dysfunctions owing to developmental problems. Due to the paucity of evidence regarding evaluation prior to and after untethering, I have shown the purpose and tools for evaluation in my own practice. This may be tailored to the types of neurogenic bladder, developmental status, and risks for deterioration. While the urodynamic study (UDS) is the gold standard test for understanding bladder function, it is not a panacea in revealing the nature of bladder dysfunction. In addition, clinicians should consider the influence of developmental processes on bladder function. Before untethering, UDS should reveal synergic urethral movement, which indicates an intact sacral reflex and lack of TCS. Postoperatively, the measurement of post-void residual urine volume is a key factor for the evaluation of spontaneous voiders. In case of elevation, fecal impaction, which is common in spinal dysraphism, should be addressed. In patients with clean intermittent catheterization, the frequency-volume chart should be monitored to assess the storage function of the bladder. Toilet training is an important sign of maturation, and its achievement should be monitored. Signs of bladder deterioration should be acknowledged, and follow-up schedule should be tailored to prevent upper urinary tract damage and also to determine an adequate timing for intervention. Neurosurgeons should be aware of urological problems related to TCS as well as urologists. Cooperation and regular discussion between the two disciplines could enhance the quality of patient care. Accumulation of experience will improve follow-up strategies.

Abstract
INTRODUCTION Bladder ultrasound is becoming pivotal in the management and treatment of lower urinary tract dysfunction. There is a paucity of data regarding intra-observer and interobserver reliability of bladder ultrasound, especially in children. A previous study assessed interobserver agreement for both the postvoid residual volume and measurement of the bladder dimensions in adults showing excellent agreement. OBJECTIVE To examine the interobserver and intra-observer reliability of bladder wall thickness, bladder urinary and postvoid residual urinary volume using ultrasound evaluated by paediatricians having different training levels. STUDY DESIGN Four sonographers, 3 pediatric trainees and one experienced pediatric urologist measured the full bladder volume, the voiding residual volume, and the bladder wall thickness. Each sonographer made 3 measurements of each parameter. We assessed the interobserver and intra-observer variability by using intraclass correlations (ICCs). ICCs were calculated and tested with a significance level of 5%. The interrater ICC was calculated from the mean of the three measurements of each variable (full bladder volume, postvoid residual, bladder wall thickness). ICC ≥0.75 was considered excellent. Bland-Altman plots were also used to assess the interobserver agreement. RESULTS Sixty children were recruited (7.3 ± 1.1 years). The interobserver ICCs for bladder volume and voiding residual volume were 0.91 (confidence interval 0.85-0.95) for both. The interobserver ICCs for the bladder wall thickness was satisfactory 0.43, with a minimum detectable difference of 2 mm. The observed values for intra-observer analysis showed an excellent (ICC ≥ 0.90) agreement between the three measurements performed by each one of the sonographers. Bland-Altman plots showed that the bias (mean difference) was -0.35 and the limits of agreement were -3.43 and 2.73 for the bladder wall thickness measurements (Figure). DISCUSSION The interobserver reliability for both the postvoid residual volume and full bladder volume were excellent even in operators with different levels of training, pointing out the role of bladder ultrasound in the routine clinical practice. Weaker agreement was found for the bladder wall thickness measurement. The intra-observer agreement was excellent for all the measurements. CONCLUSION These results showed a good reliability of urinary bladder ultrasound in children aged 7.3 ± 1.1 years as far as bladder volume measurement is concerned. Given the variability of bladder wall thickness, a standardized methodology is desirable to increase its reliability.

Abstract
BACKGROUND Urinary tract infection (UTI) during acute ischemic stroke is associated with a longer hospital length of stay and unfavorable functional outcomes. OBJECTIVE We investigated the benefits of portable bladder ultrasound (PBU) scanning during acute ischemic stroke. METHODS We retrospectively reviewed patients with acute ischemic stroke from January 2011 to February 2017. Patients were divided into group 1 (PBU not available) and group 2 (PBU available), before or after the split date, April 9, 2014. Portable bladder ultrasound scanning was conducted by nurses to measure postvoid residual urine volume in patients with impaired consciousness and/or dependent ambulation. RESULTS In total, 1928 patients were enrolled, of whom 109 (5.7%) had UTI and 901 (46.7%) experienced unfavorable outcomes (modified Rankin scale score ≥ 3). Multivariate analysis revealed that factors that influenced UTI were age of 75 years or older, female gender, initial total National Institutes of Health Stroke Scale (NIHSS) score of 5 or higher, initial NIHSS conscious score of 1 or higher, initial NIHSS leg score of 2 or higher, and urinary catheterization. Factors influencing unfavorable outcomes were similar to those influencing UTI but further comprised UTI. C-statistic for UTI detection was 0.864 for model fitting, including significant factors in logistic regression. Compared with group 1, group 2 had a higher incidence of urinary catheterization (13.1% vs 8.2%), a lower incidence of UTI (4.0% vs 6.9%), and a shorter length of stay (11.9 vs 13.6 days). CONCLUSIONS Portable bladder ultrasound scanning reduced the incidence of UTI and shortened length of stay. We suggest routine PBU procedures for patients with acute ischemic stroke who fulfill the AGN3 criteria for a high risk of UTI.

Abstract
BACKGROUND We present a consensus view from the International Children's Continence Society (ICCS) on the evaluation and management of bladder bowel dysfunction (BBD) in children with urinary tract infection (UTI). The statement aims to highlight the importance of BBD in the development and recurrence of childhood UTI and its management to reduce its associated morbidity and sequelae. METHODS A systematic literature search was done on PubMed, Embase, and Scopus databases until August 15, 2016. Relevant publications concerning BBD and its relationship with UTI among children were reviewed and aggregated for statements of recommendation. Discussion by the ICCS Board and a multi-disciplinary core group of authors resulted in a document available on its website for all ICCS members to review. Insights and feedback were considered with consensus and agreement reached to finalize this position statement. RESULTS BBD in children with UTI is summarized. Details regarding epidemiology, pathophysiology, and recommendations for general and family practitioners and pediatricians relating to the evaluation and management of this condition are presented. CONCLUSIONS This document serves as the position statement from ICCS, based on literature review and expert opinion providing our current understanding of BBD in children with UTI.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition resulting in excess androgen production. Females are typically born with ambiguous genitalia and often undergo feminising genitoplasty in infancy or childhood. Recently, there has been considerable international debate as to whether distressing urinary symptoms in CAH patients are truly present and, if so, whether these urinary problems are a consequence of the feminising genitoplasty. OBJECTIVE To identify and assess any urinary symptoms in an Australian cohort of adolescent and adult women with CAH who have undergone feminising genitoplasty in infancy, childhood or adolescence as a part of their management. STUDY DESIGN Females with CAH aged 12-40 years, who had undergone feminising genitoplasty, and were identified from a hospital database (n = 72). Those aged 12-15 years were assessed using the Paediatric Incontinence Symptom Index questionnaire in conjunction with sections of the Bristol Female Lower Urinary Tract Symptoms Scored Form questionnaire. Those aged 16-40 years were assessed using the Bristol Female Lower Urinary Tract Symptoms Scored Form questionnaire. Uroflowmetry studies and post-void residual volume ultrasounds were also conducted. Previously published normative data were used for the control population. RESULTS Responses to the questionnaire indicated that CAH patients had a higher incidence of urgency, frequency, urge incontinence, unexplained incontinence and nocturnal incontinence, when compared to previously published control data. Average and maximum urine flow rates measured by uroflowmetry were within normal range; however, the 16-40-year-old age group had significantly increased mean post-void residual volumes (P < 0.001) (Summary table). DISCUSSION The presence of lower urinary tract symptoms in these patients has previously been interpreted as a direct outcome of feminising genitoplasty; however, these results could also be accounted for by the virilisation of pelvic floor musculature. Androgens have been shown to increase skeletal muscle mass, but their exact impact on the pelvic floor musculature requires further research. Three previous studies have measured post-void residual volumes in patients with CAH, all of which found it them be raised. CONCLUSIONS Patients with CAH appeared to have overall normal urinary flow but increased post-void residual volumes. The data suggested that this population of patients has an increased probability of incontinence, urgency, and frequency when compared to a control population. These results confirmed findings of other small studies; however, it remains unclear if these changes reflected the underlying diagnosis or were a consequence of management.

Abstract
Objectives: To examine the benefits of repetitive uroflowmetry and post void residual urine (PVR) tests in children with primary nocturnal enuresis (PNE). Material and methods: Children aged ≥6 years with PNE who visited our clinics for management of enuresis were included for study. Patients were requested to complete a questionnaire including baseline characteristics and Dysfunctional Voiding Symptom Score (DVSS), 2-day bladder diary, and Rome III criteria for constipation. Two uroflowmetry and PVR tests were requested. Children with congenital or neurogenic genitourinary tract disorders were excluded. All children underwent urotherapy and desmopressin combined with anticholinergics or laxatives if indicated. The definition of abnormal flow patterns (≥1 abnormal), elevated PVR (≥1 abnormal), small maximal voided volume (MVV), nocturnal polyuria (NP) and response to treatment complied with the ICCS standardization document. Kaplan-Meier survival analysis and Cox proportional-hazards regression tests were used to evaluate the predictors of response. Results: In total, 100 children aged 8.5±2.3 years were enrolled for study (M: F=66:34) with 7.3±7.4 months of follow-up. Poor correlation was observed between DVSS/small MVV and PVR (p>0.05). Univariate analysis revealed that elevated PVR is associated with significantly less hazard of complete response to medical treatment (HR: 0.52, p=0.03), while not significantly associated with abnormal flow patterns, NP, constipation or small MVV. Multivariate analysis revealed that only elevated PVR (HR 0.30, 95% CI 0.12-0.80) and NP (HR 2.8, 95% CI 1.10-7.28) were significant predictors for complete response. Conclusions: In managing pediatric enuresis, elevated PVR is a significant predictor for lower chance of complete response to treatment whether they had high DVSS or not.

Abstract
PURPOSE OF REVIEW The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike. In the current review, we summarize the important role non-invasive testing plays in the diagnosis and management of children with LUTD and to show how use of these tests can help avoid the need for more invasive testing in the majority of children. RECENT FINDINGS Non-invasive tests such urine studies, uroflowmetry ± simultaneous electromyography, assessment of post-void residual, renal/bladder ultrasound, and pelvic ultrasound when used appropriately can provide valuable information to facilitate decision making during the evaluation of children with LUTD. While these tests should be employed prior to more invasive testing such as urodynamic studies, they can often act as a surrogate for the more invasive tests. Non-invasive tests can help us in our goal of improving diagnostic ability to better classify the child's LUTD into an actual condition which allows targeted treatment in the hope of better outcomes and more satisfied patients and families.

Abstract
BACKGROUND Spina bifida is a common cause of pediatric neurogenic bladder. It causes renal failure in almost 100% of patients if the associated detrusor sphincter dyssynergia (DSD) is inadequately managed. Detrusor instability and high detrusor pressures (Figure) have been implicated as the major factors predictive of renal damage in these patients. Urodynamic studies provide early identification of "at risk" kidneys so that appropriate intervention can be made. However, the role in post-operative patients of spina bifida who have no clinical manifestations remains unclear. OBJECTIVE To study the bladder dynamics in asymptomatic post-operative patients of spina bifida and to determine whether routine urodynamic study is justifiable. MATERIAL AND METHODS Urodynamics was performed on 15 operated patients of spina bifida who did not have any neurological deficit and were asymptomatic. RESULTS The mean age of the patients was 4.97 years. None of the patients had any urological complaints with their ultrasonography being normal. None had scars on nuclear scan. Of the 15 patients, 12 (80%) had abnormal findings on urodynamic assessment. Three patients (20%) had detrusor pressures greater than 40 cm of H2O. One patient had significant residual urine and detrusor instability. DISCUSSION The use of urodynamic studies in asymptomatic patients of spina bifida remains controversial, with one school of thought advocating early invasive urodynamic testing. In contrast, some favor noninvasive sonological monitoring, reserving invasive tests only for patients with renal tract dilatation. In our subset of patients none had renal tract dilatation but three patients (20%) had "at risk" bladders. These patients would benefit from early intervention aimed at renal preservation. The study is limited by a small sample size because of the relative rarity of the patient profile included. A further multicenter study with a case-control design could conclusively indicate the role of urodynamic testing in these patients. CONCLUSION Patients of spina bifida, even when asymptomatic, have a high incidence of unsafe bladders. Early identification and appropriate measures can protect kidneys from long-term damage, hence urodynamic profiling is mandatory for identification of potentially high-risk bladders.

Abstract
Non-neurogenic lower urinary tract dysfunction (LUTD) in children is very common in clinical practice and is important as an underlying cause of lower urinary tract symptoms, urinary tract infection and vesicoureteral reflux in affected children. LUTD in children is caused by multiple factors and might be related with a delay in functional maturation of the lower urinary tract. Behavioral and psychological problems often co-exist in children with LUTD and bowel dysfunction. Recent findings in functional brain imaging suggest that bladder bowel dysfunction and behavioral and psychiatric disorders in children might share common pathophysiological factors in the brain. Children with suspected LUTD should be evaluated properly by detailed history taking, validated questionnaire on voiding and defecation, voiding and bowel diary, urinalysis, screening ultrasound, uroflowmetry and post-void residual measurement. Invasive urodynamic study such as videourodynamics should be reserved for children in whom standard treatment fails. Initial treatment of non-neurogenic LUTD is standard urotherapy comprising education of the child and family, regular optimal voiding regimens and bowel programs. Pelvic floor muscle awareness, biofeedback and neuromodulation can be used as a supplementary purpose. Antimuscarinics and α-blockers are safely used for overactive bladder and dysfunctional voiding, respectively. For refractory cases, botulinum toxin A injection is a viable treatment option. Prudent use of urotherapy and pharmacotherapy for non-neurogenic LUTD should have a better chance to cure various problems and improve self-esteem and quality of life in affected children.

Abstract
BACKGROUND The aim of this study was to examine whether toilet-trained children with a history of febrile urinary tract infection (fUTI) and elevated postvoid residual (PVR) urine volume according to a recently published PVR nomogram were at greater risk of UTI recurrence. MATERIALS AND METHODS One month after recovery from febrile UTI, constipation was diagnosed according to the Rome III criteria, and lower urinary tract (LUT) function was evaluated with two sets of uroflowmetry and PVR by ultrasonography. For children aged ≦ 6 and ≧ 7 years, elevated PVR is defined as >20 and >10 ml, respectively. Cox proportion hazards regression was used to evaluate the risk factors for recurrence of UTI. RESULTS Between 2005 and 2011, 60 children aged 6.5 ± 2.5 years (boy:girl ratio 27:33) were enrolled for analysis. Univariate analysis showed that recurrent febrile UTI was more commonly observed in children with elevated PVR [repetitive elevated PVR: hazard ratio (HR) 5.75, 95% confidence interval (CI) 1.41-23.4; one elevated PVR: HR 4.53, 95% CI 1.01-20.2] and high-grade vesicoureteral reflux (VUR; HR 4.53, 95% CI 1.46-14.07). Multivariate analysis showed that younger age (HR 1.37, 95% CI 1.03-1.82, p < 0.01) and elevated PVR (HR 2.88, 95% CI 1.44-5.73, p = 0.01) were significant, independent risk factors for recurrent febrile UTI--but not gender, presence of high-grade VUR and constipation. CONCLUSION Elevated PVR defined by the new PVR nomogram predicted recurrent UTI in children with history of febrile UTI. Care should be taken to manage children with elevated PVR.

Underactive and overactive bladders are related to motor function and quality of life in Parkinson's disease. Int Urol Nephrol 2015; 47:751-7. [PMID: 25792006 DOI: 10.1007/s11255-015-0951-y] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2015] [Accepted: 03/07/2015] [Indexed: 12/19/2022]
Abstract
AIM OF THE STUDY Overactive bladder occurs in up to 70% and underactive bladder in up to 50% of patients with Parkinson's disease (PD), which is thought to reflect an altered frontal-basal ganglia circuit. However, it is not clear how bladder disorder is related to motor function and to quality of life (QOL) in PD. We studied these relationships by conducting multiple regression (MR) and bivariate correlation (BV) statistical analyses. METHODS We recruited 58 PD patients, irrespective of the presence of bladder disorder: 35 men and 23 women of mean age 66.8 years, mean duration of the disease 5.4 years, and median score of Hoehn-Yahr stage 3. We administered a bladder questionnaire including two major types of lower urinary tract symptoms, 'overactive bladder (OAB)' and 'voiding difficulty,' in addition to a QOL index and a pressure-flow urodynamic study to detect detrusor overactivity (DO) during filling; and detrusor weakness, outlet obstruction, and post-void residuals (PVR) during voiding. We analyzed the results using the MR and BV methods. RESULTS (1) Motor impairment (by HY grades) was significantly related to detrusor weakness (P < 0.05 MR); voiding difficulty, OAB (P < 0.05 BV) (by de novo, levodopa honeymoon, and wearing-off); and voiding difficulty (P < 0.05 MR). (2) Bladder QOL was significantly related to OAB, increased bladder sensation (P < 0.05 MR) and voiding difficulty (P < 0.05 BV). (3) Male gender was significantly related to outlet obstruction, DO (P < 0.05 MR). (4) Age was significantly related to DO and PVR (P < 0.05 MR). Disease duration was significantly related to OAB (P < 0.05 MR). CONCLUSION From these results, detrusor weakness (relevant to motor impairment) and OAB (relevant to bladder QOL) are thought to be fundamental in PD. In contrast to the mechanism of OAB, the mechanism of detrusor weakness in PD remains unclear and warrants further exploration.

Abstract
AIM The impact of the original International Children's Continence Society (ICCS) terminology document on lower urinary tract (LUT) function resulted in the global establishment of uniformity and clarity in the characterization of LUT function and dysfunction in children across multiple healthcare disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric LUT function. METHODS A variety of worldwide experts from multiple disciplines within the ICCS leadership who care for children with LUT dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. Additionally, contributions and feedback from the multidisciplinary ICCS membership were solicited. RESULTS Following a review of the literature over the last 7 years, the ICCS experts assembled a new terminology document reflecting current understanding of bladder function and LUT dysfunction in children using the 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 LUT function in children. Neurourol.
