Emergency department management of acute scrotal pain in pediatric patients.

Testicular torsion is a urologic emergency, accounting for up to 15% of cases of acute scrotal pain. Rapid recognition and management are essential to ensure viability of the testis. Doppler ultrasound can be used to confirm the diagnosis of testicular torsion; however, recent studies suggest that a more judicious use of ultrasound may be safe, decrease delays in surgical management, and avoid unnecessary utilization of resources. This issue reviews the epidemiology and historical and physical examination findings of testicular torsion and other common causes of acute scrotal pain. The existing literature is reviewed and recommendations are provided to guide the emergency clinician in appropriate management and disposition of boys with acute scrotal pain.

The development of surgical ability during pediatric urology fellowship and its evolution in the early years of practice.

BACKGROUND: North American Pediatric Urology fellowship programs underwent a structural change in 2021 that allows more flexibility in training. Given this opportunity as well as widespread concern about the development of contemporary surgical trainees, it is prudent to understand in detail the current state of preparedness of pediatric urology fellowship graduates for independent practice. OBJECTIVE: The study aimed to determine recent pediatric urology graduates' reported levels of comfort both at graduation and following the start of clinical practice in performing select index procedures. We also queried the aspects of training and clinical practice perceived to be the most valuable for the development of surgical confidence. STUDY DESIGN: Graduates of ACGME approved pediatric urology fellowships from 2016 to 2021 were surveyed. Index procedures were described via brief case vignettes. Respondents were asked to indicate their comfort level with each index procedure following fellowship graduation and at the current time point. Comfort levels were defined by the degree of support that respondents would seek from senior colleagues in preparation for case booking. Respondents were also asked about the most helpful operative settings during training and factors contributing to high and low comfort. RESULTS: Fifty-three pediatric urologists (49%) completed the survey out of 109 invited. Most respondents practiced at an academic center. Perceived comfort was very high for low complexity procedures. The responses varied more widely for procedures of moderate and significant complexity (Figure). Across the cohort, there was a substantial increase in comfort between graduation and the current time point for all procedures queried. The most highly valued operative settings in fellowship were those offering real or simulated independence. Respondents most often attributed high comfort to robust case volumes and overall surgical skill gained in fellowship. DISCUSSION: New pediatric urology faculty differ widely in surgical confidence, particularly for more complex procedures. There is meaningful growth in the confidence and self-perceived independence of pediatric urologists during their initial years of practice. The early years are a critical time of continuing maturation and development that should be supported with structured systems of mentorship. Future challenges include low case volumes for rare conditions and the centralization of complex care. CONCLUSION: These findings will provide valuable context for pediatric urology fellowship directors as they evaluate and redesign their programs under the new, more flexible structure. There are opportunities to formalize early practice mentorship to support the growth of new faculty.

Increased Hospital Encounters in Individuals With Spina Bifida Compared to the General Population: Statewide Health Care Utilization in California From 1995 to 2017.

INTRODUCTION: Our goal was to understand health care utilization by comparing hospital encounters among individuals with spina bifida and the general population and to identify the factors associated with utilization. METHODS: Using the Department of Health Care Access and Information database (1995-2017), individuals with spina bifida were identified and matched to controls by birth year. The primary outcome measures were the number of hospital encounters (stratified as ≤2 vs ≥3 encounters) and the time between the first and second encounters. Univariate, multivariate, and subgroup analyses were performed to identify factors associated with ≥ 3 encounters. RESULTS: When compared to controls, individuals with spina bifida had more ≥ 3 hospital encounters (69% vs 29%), spent more days in the hospital (58 days vs 13 days), and had a higher average charge per hospital stay ($433,537 vs $99,975) (P < .001 for all). After adjusting for covariates, we found that having spina bifida was associated with increased hospital encounters compared to controls (odds ratio 3.95, 95% CI 3.77-4.14, P < .001). Individuals with spina bifida were found to have less time between their first and second encounters (2.5 vs 3.3 years, P < .001). Within the spina bifida population, sex, race, ethnicity, comorbidities, and nonprivate insurance were associated with ≥ 3 encounters. CONCLUSIONS: Spina bifida is associated with more hospital encounters and fewer days between first and second encounters compared to the general population. These findings highlight factors driving increased utilization of resources, thereby empowering providers to better support this vulnerable population.

Genital calcinosis cutis: Microscopic evidence supporting a dystrophic origin.

Calcinosis cutis (CC) is characterized by the deposition of calcium salts in the skin and subcutaneous tissues. CC involving the vulva or foreskin (prepuce) is uncommon. We present a 9-year-old female with vulvar CC and a 15-year-old male with preputial CC. Microscopic review of excisional specimens revealed calcification associated with follicular cysts in the vulvar case and lichen sclerosus in the preputial case, suggesting a dystrophic origin to a subset of cases of genital CC that might otherwise be classified as idiopathic. The clinical implication of these findings is the need for close histopathologic scrutiny and ongoing clinical surveillance of patients with genital CC initially deemed idiopathic.

Patients With Spina Bifida Have Longer Length of Hospital Stay: Statewide Health Care Utilization in California From 1995 to 2017.

INTRODUCTION: Our goal was to better understand the health care utilization of patients with spina bifida (SB) by evaluating length of hospital stay (LOS) as well as identifying what characteristics within the SB population are contributing to shorter or longer LOS. METHODS: By querying the Department of Health Care Access and Information database of all encounters at California-licensed hospitals from January 1995 through December 2017, this study analyzed LOS as a measure of health care utilization. Patients with SB were identified using the International Classification of Diseases-9 and -10 coding system, and the data collected for both SB and control cohorts were compared using linear and logistic regression models. RESULTS: Patients with SB spent a mean LOS of 7.3 days compared to 4.7 days among the control cohort (P < .001). In multivariable analysis, SB was found to be an independent predictor of longer LOS. Within the SB encounters, increasing comorbidities and nonprivate insurance were associated with longer LOS, while being female and Hispanic were associated with a shorter LOS. CONCLUSIONS: SB is an independent predictor of longer LOS when compared to the control cohort. These findings highlight the importance of understanding the preventive health care access and needs of the vulnerable SB population to decrease hospital utilization rates.

Expert Consensus on Pediatric Urodynamics Reporting Using Modified Delphi Technique.

PURPOSE: Urodynamic testing (UDS) is an important tool in the management of pediatric lower urinary tract conditions. There have been notable efforts to standardize pediatric UDS nomenclature and technique, but no formal guidelines exist on essential elements to include in a clinical report. We sought to identify ideal structure and elements of a pediatric UDS assessment based on expert consensus. MATERIALS AND METHODS: Pediatric urologists regularly performing UDS were queried using a Delphi process. Participants were invited representing varied geographic, experience, and societal involvement. Participants underwent 3 rounds of questionnaires between November 2022 and August 2023 focusing on report organization, elements, definitions, and automated electronic health record clinical decision support. Professional billing requirements were also considered. Consensus was defined as 80% agreeing either in favor of or against a topic. Elements without consensus were discussed in subsequent rounds. RESULTS: A diverse sample of 30 providers, representing 27 institutions across 21 US states; Washington, District of Columbia; and Canada completed the study. Participants reported interpreting an average number of 5 UDS reports per week (range 1-22). The finalized consensus report identifies 93 elements that should be included in a pediatric UDS report based on applicable study conditions and findings. CONCLUSIONS: This consensus report details the key elements and structure agreed upon by an expert panel of pediatric urologists. Further standardization of documentation should aid collaboration and research for patients undergoing UDS. Based on this information, development of a standardized UDS report template using electronic health record implementation principles is underway, which will be openly available for pediatric urologists.

Delphi Consensus on Diagnostic Criteria for LUMBAR Syndrome.

OBJECTIVE: To develop consensus on diagnostic criteria for LUMBAR syndrome, the association of segmental infantile hemangiomas that affect the Lower body with Urogenital anomalies, Ulceration, spinal cord Malformations, Bony defects, Anorectal malformations, Arterial anomalies and/or Renal anomalies. STUDY DESIGN: These diagnostic criteria were developed by an expert multidisciplinary and multi-institutional team based on analysis of peer-reviewed data, followed by electronic-Delphi consensus of a panel of 61 international pediatric specialists. RESULTS: After 2 Delphi rounds, a 92% or higher level of agreement was reached for each Delphi statement. 98% of panelists agreed with the diagnostic criteria, and 100% agreed the criteria would be useful in clinical practice. The diagnosis of LUMBAR requires the presence of a segmental, or patterned, infantile hemangioma of the lumbosacral, sacrococcygeal, or pelvic cutaneous regions plus one additional criterion of the urogenital, spinal, bony, anorectal, arterial, or renal organ systems. CONCLUSIONS: These diagnostic criteria will enhance clinical care by improving screening, detection, and overall awareness of this poorly understood neurocutaneous disorder. The criteria can be utilized by a wide variety of pediatric subspecialists. In addition, formal criteria will improve phenotypic uniformity among LUMBAR syndrome cohorts and a patient registry, allowing investigators to assess clinical features, long-term outcomes, and results of genetic sequencing in a standardized manner. Finally, these criteria will serve as a starting point for prospective studies to establish formal screening and management guidelines.

Urinary tract infections in pediatric orthopedic surgical patients: a Single Institution National Surgical Quality Improvement Program Study.

OBJECTIVE: Perioperative urinary tract infections (UTIs) are poorly studied among pediatric orthopedic surgical patients. We evaluated the incidence of and risk factors for UTI in a large volume of pediatric orthopedic surgical patients. METHODS: Children <18 who underwent orthopedic surgery between March 2015 and December 2018 were analyzed using our institution's National Surgical Quality Improvement Program (NSQIP) data. Demographic, perioperative and outcome data of patients who developed a UTI within 30 days of surgery were compared to patients without UTI. RESULTS: NSQIP data were available for 520 surgeries (324 girls and 196 boys). Median age at surgery was 13.5 years. A Foley was placed in 301/520 cases (88/196 boys and 213/324 girls) in 264 children. Six cases of UTI occurred within 30 days of surgery (1.2% of surgeries). The UTI rate among patients with a Foley was 2.3%, and among girls with a Foley was 2.8%. No UTIs occurred without a Foley, nor any in boys. All six occurred in the American Society of Anesthesiologists Class 2 females, ages 7-15 undergoing elective surgery with Foley for over 48 h. Factors associated with an increased odds of developing UTI included: higher BMI [OR, 1.12 (CI, 1.01-1.22; P  = 0.03)], developmental delay [OR, 7.82 (CI, 1.40-43.7; P  = 0.02)], structural central nervous system abnormality [OR, 17.5 (CI, 3.89-90.4; P  = 0.01)], longer duration with Foley [OR, 1.68 (CI, 1.22-2.32; P  = 0.002)] and hospital readmission within 30 days [OR 14.2 (CI, 2.32-87.3; P  = 0.004)]. CONCLUSION: Risk of UTI is low after pediatric orthopedic surgery. Girls with comorbidities including structural central nervous system abnormality, developmental delay and higher BMI with prolonged Foley catheterization may have higher postoperative UTI risk. Level of Evidence: II.

Patient Characteristics Associated with Sexual Interest and Activity Among Adults with Spina Bifida.

OBJECTIVE: To identify factors associated with sexual interest and activity among adults with spina bifida and to describe the sexual profile of those who were sexually active. Sexual health of adults with spina bifida is often neglected and current knowledge on the topic is limited. METHODS: An anonymous web-based survey was advertised and administered between March 2018 and September 2018 and participants 16 years and older with spina bifida were included in this study. Respondents were asked about sexual interest, activity, and function using the validated Patient-Reported Outcomes Measurement Information System Sexual Function Profile. Bivariate and multivariable models with ordinal logistic regression were fitted to evaluate predictors of sexual interest and sexual function. RESULTS: Of the 261 respondents with a self-reported diagnosis of spina bifida (mean age of 38.5 years), 73.2% noted at least a little bit of interest in sexual activity. In multivariate analysis, women were less likely to report higher sexual interest than men (odds ratio (OR) = 0.53, 95% CI 0.31-0.92, P = .03) whereas those with higher physical functioning were more likely to have higher sexual interest (OR = 1.04, confidence interval (CI) 1.01-1.07, P = .03). Just less than half of respondents (46.4%) were sexually active in the past 30 days, and those with a ventriculoperitoneal shunt were less likely to engage in sexual activity compared to those without (OR = 0.36, 95% CI 0.19-0.68; P <.01). CONCLUSION: The mismatch between sexual interest and sexual activity highlights the importance of exploring issues related to sexual health when counseling adult patients with spina bifida.

Access and Utilization of Health Care by Adults with Spina Bifida.

OBJECTIVE: To contextualize the challenges that persons with congenital genitourinary conditions (CGC) may encounter in adulthood, we examined health care access, readiness for self-management, and health care utilization of adults with spina bifida (SB). METHODS: Through surveys distributed via social media, persons with SB were asked about access and barriers to care, readiness for self-management, and health care utilization (ie, medical visits, missed visits, emergency room [ER] visits, hospital admissions) within the past year. Multivariable models were fitted to examine determinants of utilization. RESULTS: Of the 270 eligible respondents (mean age 39), 24.5% had not received care from a urologist in the past year. The odds of missing any medical visits were increased among those with more prior urologic surgeries (odds ratio (OR) 1.35, 95%confidence interval (CI) 1.05-1.78) and those with ER visits for urologic condition within the past year (OR 2.65, 95%CI 1.22-6.01). Those with private insurance had lower odds of having ER visits for urologic condition (OR 0.46, 95%CI 0.22-0.84). The odds of hospital admission related to urologic condition were increased among female (OR 2.35, 95%CI 1.01-6.64), those with more prior urologic surgeries (OR 1.18, 95%CI 1.09-1.51), and those with a urologist (OR 2.98, 95%CI 1.15-14.47). CONCLUSION: A substantial proportion of adults with CGC lack routine urologic care. Considering the significant barriers to care and lapses in care, efforts to improve access and optimize health care services utilization for this population with high medical complexity are warranted.

Revisiting the utility of prenatal ultrasound in the routine workup of first febrile UTI: A systematic review and meta-analysis of the negative predictive value of prenatal ultrasound for identification of urinary tract abnormalities after first febrile urinary tract infection in children.

CONTEXT: The current EAU/ESPU and recently retired AAP pediatric UTI guidelines recommend renal bladder ultrasound after first febrile UTI in children to screen for structural abnormalities, regardless of findings on prenatal ultrasound. OBJECTIVE: Test the hypothesis that a normal prenatal ultrasound could rule out urinary tract abnormality on post-UTI ultrasound. DATA SOURCES: Medline, Embase, Cochrane Library. STUDY SELECTION: Studies including pediatric patients with first febrile UTI who had both prenatal and post-UTI ultrasound. DATA EXTRACTION: Anatomical abnormalities detected by prenatal and post-UTI ultrasound as reported per individual study criteria were extracted. Meta-analyses of 9 studies (2981 patients) were performed using a random-effects model and composite estimates of the negative predictive value (NPV) of prenatal ultrasound were calculated. RESULTS: Overall summary NPV of prenatal ultrasound for all pediatric patients was 77%, with heterogeneity score (I2) 97.9%. Summary NPV of prenatal ultrasound for all patients under two years of age was similar at 75%, with I2 98.2% For the 4 studies to which we could apply a more stringent definition of abnormality, summary NPV was 85% and I2 97.5% for prediction of moderate post-UTI ultrasound abnormalities and summary NPV was 93% and I2 90.4% for severe abnormalities. DISCUSSION: While we calculated an 85% NPV for a normal prenatal ultrasound to rule out significant postnatal abnormality as defined within individual studies, substantial heterogeneity amongst publications limited the precision of our estimates. This highlights the need for more rigorous investigations with attention to timing of ultrasound and the application of clinically meaningful definitions for abnormal prenatal and post-UTI studies. This may allow judicious use of prenatal ultrasound to guide clinical management for children with first febrile UTI and minimize redundant imaging with potential for false positive results. Until then, the current guidelines are justified based on the limited and heterogenous data from the currently available published studies.

Repurposing an ACE Malone Channel for Continent Intermittent Catheterization During Re-augmentation Cecocystoplasty: The MACEtrofanoff Procedure.

OBJECTIVE: To describe a surgical alternative option in select patients with neurogenic bladder and a history of Malone antegrade continence enema (MACE) who now require revision augmentation of the bladder, and/or creation of a new continent catherizable urinary channel (CCC). METHODS: Herein, we describe a novel surgical approach for patients who have had prior MACE creation who subsequently require surgical revision and creation of a new CCC. Rather than the traditional approach of creating a new CCC utilizing bowel, we perform a cecocystoplasty and leave the previously created MACE intact. The prior MACE channel becomes repurposed as the new Mitrofanoff, which we have termed the MACEtrofanoff channel. Concomitant cecostomy tube placement for bowel management can be performed at the time of surgery. RESULTS: We have successfully performed this procedure in 2 patients with good outcomes to date. This technique does not require the sacrifice of the prior appendix channel, nor require the formation of a new stoma and channel. Patients are able to adapt easily to clean intermittent catheterization through a channel they are already familiar with for their prior antegrade enemas. CONCLUSION: In select patients, surgeons should consider the MACEtrofanoff procedure to avoid the added morbidity of further bowel mobilization.

Health care utilization in young adults with childhood physical disabilities: a nationally representative prospective cohort study.

BACKGROUND: Young people with physical disabilities face barriers to accessing health care; however, few studies have followed adolescents with physical disabilities longitudinally through the transition of care into adulthood. The objective of this study was to investigate differences in health care utilization between adolescents with physical disabilities and those without during the transition period from adolescent to adult care. METHODS: We utilized the National Longitudinal Study of Adolescent to Adult Health, a prospective cohort study following adolescents ages 11-18 at baseline (1994-1995) through adulthood. Baseline physical disability status was defined as difficulty using limbs, using assistive devices or braces, or having an artificial limb; controls met none of these criteria. Health care utilization outcomes were measured seven years after baseline (ages 18-26). These included yearly physical check-ups, unmet health care needs, and utilization of last-resort medical care, such as emergency departments, inpatient hospital wards, and inpatient mental health facilities. Multiple logistic regression models were used to predict health care utilization, controlling for age, sex, race/ethnicity, insurance status, and history of depression. RESULTS: Thirteen thousand four hundred thirty-six participants met inclusion criteria, including 4.2% with a physical disability and 95.8% without. Half (50%) of the sample were women, and the average age at baseline was 15.9 years (SE = 0.12). In logistic regression models, those with a disability had higher odds of unmet health care needs in the past year (Odds Ratio (OR) 1.41 95% CI 1.07-1.87), two or more emergency department visits in the past five years (OR 1.34 95% CI 1.06-1.70), and any hospitalizations in the past five years (OR 1.36 95% CI 1.07-1.72). No statistically significant differences in preventive yearly check-ups or admission to mental health facilities were noted. CONCLUSIONS: Young adults with physical disabilities are at higher risk of having unmet health care needs and using last-resort health care services compared to their non-disabled peers.

Feasibility of Awake Intravesical Botulinum Toxin Injection in Pediatric Neurogenic Bladder.

PURPOSE: Cystoscopic injection of botulinum neurotoxin (BoNT) is typically performed under general anesthesia in pediatric patients with neurogenic bladder, accumulating anesthetic exposures and operating room costs. As most of these patients already tolerate clean intermittent catheterization (CIC), it has become our practice to offer a trial of awake injection. We report our initial experience here. We hypothesized that higher sensory level, female sex and absence of mental health issues or cognitive delay might predict successful first awake injection and decreased operative times. MATERIALS AND METHODS: Surgical records from 2 academic hospitals from 2018-2020 were reviewed. Generalized linear models were fit to determine predictors of success and procedural length. RESULTS: Trial of awake injection was offered to 22 patients. Eighteen patients (8 female, 10 male, 4-20 years old) elected to proceed. All 18 patients were managed with CIC at baseline, 14 had anxiety or behavioral issues, 10 had cognitive delay and 7 had sensory level below S2. Two patients (11%) required conversion to general anesthesia and one of these subsequently opted for a repeat awake injection trial. Fifteen of the 18 patients (83%) had or planned subsequent injections awake. Of the remaining, 1 proceeded to bladder augment, 1 is considering ileovesicostomy and 1 requested subsequent injections under anesthesia. No intraoperative complications occurred. CONCLUSIONS: Awake BoNT injection is feasible in pediatric patients with neurogenic bladder managed with CIC, even in the setting of intact sensation, well-managed mental health issues or cognitive delay, thereby increasing the viability of BoNT as an early tool in the management of neurogenic bladder.

Young Adult Healthcare Exposure and Future Opioid Misuse: A Prospective Cohort Study.

INTRODUCTION: Outpatient opioid prescribing is associated with opioid misuse in young adults, but the longitudinal association between general healthcare exposure and opioid misuse has not been explored. The objective of this study is to examine the association between healthcare exposure in young adulthood and future opioid misuse. METHODS: Data were drawn from the National Longitudinal Study of Adolescent to Adult Health (2001-2018) and analyzed in 2021. Healthcare exposure (i.e., inpatient hospitalization and visits to the clinic, emergency department, mental-health facility, or dentist) between individuals aged 18 and 26 years was the primary independent variable; only patients who did not report opioid misuse at baseline were included. Opioid misuse was defined as using prescription painkillers without a doctor's permission and was measured 17 years after exposure. Multivariable logistic regression was used to examine any associations with opioid misuse (ages 33-43 years). RESULTS: A total of 8,225 young adults with a mean baseline age of 21.8 (SE=0.12) years met inclusion criteria. Approximately 13.7% reported new opioid misuse at follow-up. Those reporting opioid misuse at follow-up were more likely to be White, lack a college education, or report depression. Those exposed to inpatient hospitalization, emergency departments, or mental-health facilities had an increased risk of future opioid misuse. CONCLUSIONS: In young adults reporting no opioid misuse at baseline, healthcare exposure was associated with an increased risk of opioid misuse later in adulthood in this large, national cohort. Physicians encounter this at-risk population daily, reinforcing the importance of responsible prescribing practices and the need for targeted screening, patient education, and intervention efforts in the healthcare setting.

A Child's urine is not sterile: A pilot study evaluating the Pediatric Urinary Microbiome.

INTRODUCTION: A bladder microbiome (urobiome) exists in adults. Data supports the effects of the adult urobiome on urinary tract health with associations between dysbiotic urobiomes and lower urinary tract disorders. Understanding urobiome origin is important since other microbiomes establish around birth and microbiome alterations are linked to disease development. However, the pediatric urobiome has not been well studied. OBJECTIVES: We sought to determine the age when the urobiome develops, compare the pediatric urobiome to microbiomes of adjacent urogenital niches, and compare the urobiomes between boys and girls and across age groups. STUDY DESIGN: Seventy-four children less than 18 years of age without recent antibiotic exposure were recruited, including 48 males and 26 females, aged 2 weeks to 209 months of age. Transurethral catheterized urine samples and samples from the perineum, urethra, vagina, and foreskin were collected. Specimens were assessed using the expanded quantitative urine culture protocol and by 16S rRNA gene sequencing. Dada2 was used to profile microbial compositions, and BLCA was used to identify microbial taxa. RESULTS: Bacteria were detected in 90.5% of urine samples and identified in children as young as 2 weeks of age. Microbial communities and compositions of the female bladder and other urogenital niches (urethra, perineum, and vagina) differed significantly by age. Lactobacillus predominated the bladder, urethral, and vaginal microbiomes in post-pubertal girls. Compared to female urinary microbiomes, those of males differed less substantially. Only perineal microbiomes differed significantly by age, whereas male urethral and foreskin microbiomes did not differ significantly. DISCUSSION: We identified that a urinary microbiome is established as early as infancy. In addition, the female urobiome changes throughout childhood, until the post-pubertal bacterial taxa becomes consistent with that seen in adult females. Whereas in boys, the urinary microbiome changed very little over time. In addition, the surrounding urogenital microbiomes differed less in boys as compared to females. Microbiomes established at a young age may have long-term influences on immune, metabolic, and neurobehavioral traits. The same may be true for the urobiome. Our study provides a foundation for future research to determine the influence of the pediatric urobiome on the development of urinary and even non-urinary disorders. CONCLUSIONS: A pediatric urobiome exists, with differences between males and females and can be detected at a young age with changes occurring throughout childhood. Similarities and differences are also seen between the pediatric urobiome and adjacent niches.
