A systematic review of interventions for reducing pain and distress in children undergoing voiding cystourethrography

Imaging characteristics predicting elevated detrusor pressures in patients with spina bifida

PURPOSE

Patients with spina bifida require urologic follow up with assessments of bladder and renal function. The ideal screening protocol for bladder compliance remains controversial. This study assessed associations between bladder end filling pressure (EFP) and detrusor leak point pressure (DLPP) on urodynamic studies (UDS) and findings from renal bladder ultrasounds (RBUS) and voiding cystourethrograms (VCUG).

METHODS

Pediatric spina bifida patients who underwent RBUS and/or VCUG within six months of UDS at a single institution from 2015 to 2021 were retrospectively reviewed. Demographics, VCUG and RBUS results, and UDS EFP and DLPP were recorded. Multiple linear regression analyses and Pearson chi-square tests were conducted to correlate RBUS and VCUG findings with DLPP/EFP.

RESULTS

129 patients were included. In adjusted analyses, moderate to severe hydronephrosis on RBUS was significantly associated with elevations in mean DLPP/EFP (p = 0.006). Patients with round bladders had significantly lower mean DLPP/EFP than patients with elongated or conical bladders (p < 0.0001). The presence of trabeculations was associated with increased mean DLPP/EFP (p < 0.0001) and increases in severity of trabeculations were associated with higher DLPP/EFP (p < 0.0001). The presence of vesicoureteral reflux (VUR) on VCUG was not associated with significant differences in mean DLPP/EFP (p = 0.20).

CONCLUSIONS

Abnormal bladder shape and trabeculations on VCUGs in spina bifida patients had significant associations with increased mean bladder pressures on UDS. Assessment of bladder shape and contour by VCUG may be a valuable screening tool in conjunction with routine RBUS in determining the need for further assessment of bladder pressures in patients with spina bifida.

The accuracy of cystography under general anesthesia in children with vesicoureteral reflux

PURPOSE

To examine the accuracy of cystography under general anesthesia in children with vesicoureteral reflux (VUR).

MATERIALS AND METHODS

A prospective study of children who had VUR on cystography without general anesthesia (i.e., the gold-standard), and who are candidates for endoscopic VUR repair surgery. All children subsequently underwent a cystography under general anesthesia before injection using standardized method, which was compared to the gold-standard cystography. χ² and Mann-Whitney U tests were used to compare proportions and medians between groups.

RESULTS

Between 2017 and 2021, 126 renal units in 13 boys and 50 girls were included. Median age was 3.4 years (interquartile range [IQR] 1.5-6.5). Median time from cystography without to cystography with general anesthesia was 3.8 months (IQR 2.7-6). Of the 126 renal units, 96 had VUR on cystography without general anesthesia. On dichotomous analysis (no VUR vs. any VUR) sensitivity, specificity, negative and positive predictive values of cystography under general anesthesia were 47% (45/96), 87% (26/30), 34% (26/77) and 92% (45/49), respectively. Accuracy was 56.3%; Cohen's Kappa coefficient was 0.22, indicating poor agreement. In subgroup analysis, the sensitivity of cystography under general anesthesia was significantly lower in primary VUR (20% vs. 55% in secondary VUR, p = 0.01) and active VUR (14% vs. 52% in passive VUR, p = 0.008).

CONCLUSION

Cystography under general anesthesia was poorly correlated to cystography performed while the child was awake or lightly sedated. Clinical decision relying on this cystography is questionable.

Secular trends in physical fitness of Slovenian boys and girls aged 7 to 15 years from 1989 to 2019: a population-based study

Using the population-based data we aim to estimate the general population trends of multiple components of physical fitness of children, identify critical structural changes in these trends, and evaluate the potential changes in differences in the test scores between the children. During the entire study period, 1989-2019, median body mass index and triceps skinfold increased in both genders and all age groups. Muscular fitness, in general, showed negative trends, with some exceptions: during the post-2010 period, children were mostly experiencing the improvement of isometric strength of the upper body. The neuromuscular components of physical fitness showed positive trends, especially in girls. Cardiorespiratory fitness has been declining in all age groups until the last decade, with the largest decreases occurring before 2000. In the last decade, the trends reversed. The flexibility indicator revealed the largest differences between boys and girls, with boys mainly experiencing negative and girls mostly positive trends. The variability of the test scores mostly increased during the study period. This increasing variance suggests that-despite generally favourable trends in the last decade-children in Slovenia have been facing increasing inequalities in their development, which can potentially lead to future inequalities in health.

Characteristics and Outcomes of Patients Receiving Sedation for Voiding Cystourethrography

Background

Voiding cystourethrography (VCUG) is used to diagnose vesicoureteral reflux (VUR); however, it is an invasive procedure and can be psychologically distressing. Procedural sedation is occasionally utilized to alleviate anxiety during VCUG, and some patient populations may get referred more readily for sedation than others. Sedative medications may also impact the results of the test due to their effects on smooth muscle. The goals of this study were to compare patient characteristics between those that were referred for procedural sedation and those that were not and to compare VCUG results between sedated and non-sedated patients.

Methodology

We performed a retrospective cohort study of patients aged 2-18 years undergoing VCUG during a five-year period. Sedated patients were matched with non-sedated patients controlling for referring provider and procedure year. Exclusion criteria included chronic catheterization, same-day surgery, current intensive care admission, and sedation restrictions. A total of 284 patients were included. Demographic information, medical comorbidities, and VCUG results were analyzed.

Results

There were no significant differences between sedated and non-sedated patients in any demographic variables. Neurologic, developmental, and gastrointestinal comorbidities were more common in sedated patients. On multivariate analysis, having more than one comorbid condition was the only significant predictor of referral for procedural sedation. There were no significant differences in VCUG results between sedated and non-sedated patients.

Conclusions

Patients with comorbidities were more likely to receive procedural sedation for VCUG. Procedural sedation did not have a significant impact on test results, suggesting its potential utility in relieving pain and anxiety associated with VCUG.

Gentle Touch: Noninvasive Approaches to Improve Patient Comfort and Cooperation for Pediatric Imaging

Pediatric imaging presents unique challenges related to patient anxiety, cooperation, and safety. Techniques to reduce anxiety and patient motion in adults must often be augmented in pediatrics, because it is always mentioned in the field of pediatrics, children are not miniature adults. This article will review methods that can be considered to improve patient experience and cooperation in imaging studies. Such techniques can range from modifications to the scanner suite, different ways of preparing and interacting with children, collaborating with parents for improved patient care, and technical advances such as accelerated acquisition and motion correction to reduce artifact. Special considerations for specific populations including transgender patients, neonates, and pregnant women undergoing fetal imaging will be described. The unique risks of sedation in children will also be briefly reviewed.

The effects of primary and recurrent pediatric urological surgeries on parental anxiety levels

INTRODUCTION

Invasive diagnostic and therapeutic procedures in pediatric urology may generally cause distress and pain in children. As a result, it may have a negative effect on adult and child behaviors. The anxiety, depression levels or distress and fear status caused by recurrent diseases or repetitive medical interventions in adult patients or the parents of pediatric patients have been investigated previously.

OBJECTIVE

To the best of our knowledge, we have not found a study evaluating the effects of primary or recurrent pediatric urological operations on parental anxiety. Our main aim was to compare the effects of primary and repetitive pediatric urological surgeries on the anxiety levels of both mothers and fathers. We also aimed to investigate the effects of other factors related to parents and children on parental anxiety.

DESIGN

A total of 163 patients under 14 years old who had undergone primary or recurrent pediatric urological operations and also their parents were included in a prospective, cross-sectional study. Demographic and clinical data of the patients and their parents were recorded. Before the surgeries, the Children's Fear Scale was applied to all patients over 3 years old and the State-Trait Anxiety Inventory was applied to all parents. The participants were divided into two main groups: primary surgery group (n:84) and recurrent surgery group (n:79). A subgroup analysis was performed according to surgery type (day surgery, minor surgery and major surgery).

RESULTS

We found that repetitive surgeries, higher fear scores of children, parents' being younger, having low education level, not having enough information about the surgeries and presence of someone in the immediate vicinity who previously experienced the same surgery increased parental anxiety levels. Day surgeries did not affect fathers' state anxiety levels as much as minor and major surgeries, whereas mothers' state anxiety levels were higher than fathers' regardless of the surgery type. Children's fear level was not affected by child age, gender, surgery type or previous history of surgery.

DISCUSSION

The majority of studies in the literature show no significant difference in terms of pain and fear levels in pediatric patients undergoing repeated diagnostic interventions but there are contradictory results about parental anxiety levels. There is also a lack of studies on the effects of recurrent surgeries.

CONCLUSION

According to our findings, repetitive surgeries and presence of someone who previously experienced the same surgery are the most significant predictive factors increasing parental anxiety levels.

Pediatric voiding cystourethrography: An essential examination for urologists but a terrible experience for children

Voiding cystourethrography is the most important fluoroscopic examination in pediatric urology for the investigation of lower urogenital tract diseases, such as vesicoureteral reflux or urethral stricture. However, this invasive procedure imposes a significant burden on children and their parents, and recently there has been a paradigm shift in the diagnosis and treatment of vesicoureteral reflux. In the 2011 revision, the American Academy of Pediatrics guidelines on urinary tract infection recommended abandoning routine voiding cystourethrography after the first febrile urinary tract infection. In 2014, the randomized intervention for children with vesicoureteral reflux study recommended discontinuation of routine continuous antibiotic prophylaxis for vesicoureteral reflux. The time is now ripe to radically reconsider indications for voiding cystourethrography and the procedure itself.

Utility of sedation for young children undergoing dimercaptosuccinic acid renal scans

BACKGROUND

No studies have examined whether use of sedation during a Tc-99 m dimercaptosuccinic acid (DMSA) renal scan reduces patient discomfort.

OBJECTIVE

To compare discomfort level during a DMSA scan to the discomfort level during other frequently performed uroradiologic tests, and to determine whether use of sedation during a DMSA scan modifies the level of discomfort.

MATERIALS AND METHODS

We examined the discomfort level in 798 children enrolled in the Randomized Intervention for children with Vesicoureteral Reflux (RIVUR) and Careful Urinary Tract Infection Evaluation (CUTIE) studies by asking parents to rate their child's discomfort level with each procedure on a scale from 0 to 10. We compared discomfort during the DMSA scan and the DMSA image quality between centers in which sedation was used >90% of the time (sedation centers), centers in which sedation was used <10% of the time (non-sedation centers), and centers in which sedation was used on a case-by-case basis (selective centers).

RESULTS

Mean discomfort level was highest for voiding cystourethrogram (6.4), followed by DMSA (4.0), followed by ultrasound (2.4; P<0.0001). Mean discomfort level during the DMSA scan was significantly higher at non-sedation centers than at selective centers (P<0.001). No difference was apparent in discomfort level during the DMSA scan between sedation centers and selective centers (P=0.12), or between the sedation centers and non-sedation centers (P=0.80). There were no differences in the proportion with uninterpretable DMSA scans according to sedation use.

CONCLUSION

Selective use of sedation in children 12-36 months of age can reduce the discomfort level experienced during a DMSA scan.

Distress experienced during pediatric VCUGs - a granular, prospective assessment using the brief behavioral distress scale

BACKGROUND

In spite of decades of experience with the procedure, controversy persists as to the overall distress experienced by children and the routine need for sedation in children undergoing voiding cystourethrograms (VCUG). Many studies have attempted to address these issues, often divided into one camp that champions routine sedation while another group believes that pretest preparation is often all that is needed. At the root of these issues are some of the limitations of previous studies as most incorporate inherently subjective parental questionnaires to determine distress levels rather than using an objective, unbiased observer.

OBJECTIVE

The objective of this study is to use a validated and reliable tool (the brief behavioral distress scale) to objectively evaluate the distress experienced during VCUGs.

MATERIALS AND METHODS

A prospective study of 26 children (ages 3-7 years old) was performed by the pediatric radiology department at a large urban academic medical center. Patients were evaluated for distress during 12 separate VCUG steps beginning with the patient entering the room and ending with the clothing being replaced at study completion.

RESULTS

Using a general linear model (repeated measures analysis of variance (ANOVA)), significant distress was identified during two phases of the examination, catheter insertion (P-values ranging <0.001-0.19) and the full bladder phase (P-values ranging 0.005-0.043). The mean distress score for catheter insertion (mean: 1.38, standard deviation [SD]: 1.098) was nearly three times higher than the next most distressful step, i.e. full bladder (mean: 0.65, SD: 0.745). Additionally, entering the room was perceived as significantly more distressing than the catheter out (P = 0.016) and clothing replacement phase (P = 0.006).

CONCLUSION

We find that despite there being significantly increased distress during the catheter insertion and full bladder phases, the distress levels during VCUGs are markedly less than in previous reports. Even the most distressful stage, catheterization, was less stressful than previously reported with levels closer to that of minor distress evinced by comfort-seeking behavior from a parent rather than more significant distress resulting in screaming. Our findings corroborate and expand on the conclusion of the effectiveness of pretest preparation and child life specialist involvement.

Is top-down vs bottom-up radiological evaluation after febrile urinary tract infection really less stressful for the child and family? Challenging the dogma

PURPOSE

We evaluated whether stress levels in children and parents during radiological evaluation after febrile urinary tract infection are really lower using the top-down approach, where (99m)technetium dimercaptosuccinic acid renal scintigraphy is used initially, than the bottom-up approach, where voiding cystourethrography is initially performed and repeated examinations are easier for all.

MATERIALS AND METHODS

We prospectively evaluated 120 children 3 to 8 years old. Pain ratings were obtained using the Faces Pain Scale-Revised, and conversation during the procedure was evaluated using the Child-Adult Medical Procedure Interaction Scale-Revised by 2 independent observers. To evaluate parental anxiety, the State-Trait Anxiety Inventory form was also completed. Following a documented febrile urinary tract infection children were randomized to the top-down or bottom-up group. A third group of 44 children undergoing repeat voiding cystourethrography and their parents were also evaluated.

RESULTS

Child ratings of pain using the Faces Pain Scale-Revised were not significantly different between the top-down group following (99m)technetium dimercaptosuccinic acid renal scintigraphy (2.99 on a scale of 10) and the bottom-up group following voiding cystourethrography (3.21). Also the Faces Pain Scale-Revised was not significantly different in the repeat voiding cystourethrography group (3.35). On the Child-Adult Medical Procedure Interaction Scale-Revised there was negative correlation between child coping and child distress, as well as rate of child distress and adult coping promoting behavior. Parental state anxiety scores were significantly less in the top-down and repeat voiding cystourethrography groups than in the bottom-up group.

CONCLUSIONS

Although the top-down approach and repeat voiding cystourethrography cause less anxiety for caregivers, these values do not correlate to pain scale in children. This finding might be due to lack of appropriate evaluation tools of pediatric pain and anxiety. However, the theory that the top-down approach is less invasive, and thus less stressful, requires further research. The Child-Adult Medical Procedure Interaction Scale-Revised data indicate that influences in adult-child interaction are bidirectional.

Analysis of an intervention to reduce parental anxiety prior to voiding cystourethrogram

PURPOSE

The voiding cystourethrogram (VCUG) is a common imaging test in pediatric urology that can be associated with anxiety in the child and parent. We hypothesized that education by mailed brochure would decrease pre-procedure parental anxiety.

METHODS

Families of children scheduled for VCUG were randomized into an experimental group that was mailed an educational brochure about the VCUG and a control group. Immediately prior to the procedure, parental anxiety was assessed with the self-administered State-Trait Anxiety Inventory (STAI). The parent repeated the STAI at home after the VCUG and answered brief questions about educational resources used to prepare for the VUCG.

RESULTS

We enrolled 105 families (47 experimental, 58 control). Parental state anxiety was higher before the procedure than after the procedure (p < 0.001). Younger parents had greater pre-procedure state anxiety (p = 0.007). Contrary to our expectations, pre-procedure state anxiety did not differ between control and experimental groups. However, parents in the experimental group demonstrated less anxiety with some individual items in the questionnaire.

CONCLUSION

An educational brochure mailed to families prior to VCUG did not decrease pre-procedure parental state anxiety. However, the educational brochure can ensure accurate dissemination of information to help families prepare for this potentially distressing procedure.
