Pediatric urinary tract infection (UTI) costs the health care system more than $180 million annually, and accounts for more than 1.5 million clinician visits per year. Accurate and timely diagnosis of these infections is important for determining appropriate treatment and preventing long-term complications such as renal scarring, hypertension, and end-stage renal disease. After the first 12 months, girls are more likely to be diagnosed with a UTI. About half of boys with UTI are diagnosed within the first 12 months of life. Diagnosis of UTI is made based on history and examination findings and confirmed by urine testing.

Objective

Augmentation cystoplasty (AC) is a major surgery that can be associated with long-term morbidity. This study aimed to describe the cumulative incidence of outcomes and urologic procedures in a large cohort of children who underwent AC, identify significant sources of morbidity, and to evaluate baseline factors associated with outcomes of interest.

Methods

Children≤18 years who underwent AC in the Pediatric Health Information System from 1999 to 2010 were included. All follow-up encounters up to June 2012 were included. Cumulative incidences for 15 outcomes and urologic procedures were calculated using non-informative censoring. Sensitivity analyses were performed to determine effect of censoring assumptions and including hospitals without complete datasets. As an exploratory analysis, baseline patient factors were evaluated for associations with outcomes and urologic procedures of interest using multivariable Cox proportional hazards models adjusted for clustering by hospital.

Results

2831 AC patients were identified. Based on cumulative incidence calculations and sensitivity analyses; the cumulative incidence ranges of outcomes and procedures at 1, 3, 5, and 10 years were calculated. Examples of 10-year cumulative incidence ranges are given for the following outcomes and procedures: bladder rupture (2.9-6.4%), small bowel obstruction (5.2-10.3%), bladder stones (13.3-36.0%), pyelonephritis (16.1-37.1%), cystolithopaxy (13.3-35.1%), and reaugmentation (5.2-13.4%). The development of chronic kidney disease was strongly associated with a diagnosis of lower urinary tract obstruction (HR 13.7; 95% CI 9.4-19.9). Bladder neck surgery and stoma creation at time of AC were associated with an increased hazard of bladder rupture (HR 1.9; 95% CI 1.1-3.3) and bladder stones (HR 1.4; 95% CI 1.1-1.8) respectively.

Conclusions

Outcomes of interest and urologic procedures after AC are common. Results from this large cohort can be used to counsel patients and families about expectations after AC. Pyelonephritis, chronic kidney disease, further reconstructive surgery, and calculus disease appear to cause significant morbidity. Collaborative efforts are needed to further reduce morbidity in this patient population.

Purpose

Secondary data analysis is the use of data collected for research by someone other than the investigator. In the last several years there has been a dramatic increase in the number of these studies being published in urological journals and presented at urological meetings, especially involving secondary data analysis of large administrative data sets. Along with this expansion, skepticism for secondary data analysis studies has increased for many urologists.

Materials and methods

In this narrative review we discuss the types of large data sets that are commonly used for secondary data analysis in urology, and discuss the advantages and disadvantages of secondary data analysis. A literature search was performed to identify urological secondary data analysis studies published since 2008 using commonly used large data sets, and examples of high quality studies published in high impact journals are given. We outline an approach for performing a successful hypothesis or goal driven secondary data analysis study and highlight common errors to avoid.

Results

More than 350 secondary data analysis studies using large data sets have been published on urological topics since 2008 with likely many more studies presented at meetings but never published. Nonhypothesis or goal driven studies have likely constituted some of these studies and have probably contributed to the increased skepticism of this type of research. However, many high quality, hypothesis driven studies addressing research questions that would have been difficult to conduct with other methods have been performed in the last few years.

Conclusions

Secondary data analysis is a powerful tool that can address questions which could not be adequately studied by another method. Knowledge of the limitations of secondary data analysis and of the data sets used is critical for a successful study. There are also important errors to avoid when planning and performing a secondary data analysis study. Investigators and the urological community need to strive to use secondary data analysis of large data sets appropriately to produce high quality studies that hopefully lead to improved patient outcomes.

Antibiotics are a mainstay in the treatment of bacterial infections, though their use is a primary risk factor for the development of antibiotic resistance. Antibiotic resistance is a growing problem in pediatric urology as demonstrated by increased uropathogen resistance. Lack of urine testing, nonselective use of prophylaxis, and poor empiric prescribing practices exacerbate this problem. This article reviews antibiotic utilization in pediatric urology with emphasis on modifiable practice patterns to potentially help mitigate the growing rates of antibiotic resistance. This includes urine testing to only treat when indicated and tailor broad-spectrum therapy as able; selective application of antibiotic prophylaxis to patients with high-grade vesicoureteral reflux and hydronephrosis with counseling regarding the importance of compliance; and using local antiobiograms, particularly pediatric-specific antiobiograms, with inpatient versus outpatient data.

Introduction

In 2017, UCSF established a formal Transitional Urology (TU) clinic co-run by pediatric and adult urology aimed at providing comprehensive urologic care for people progressing into adulthood with complex urologic histories.

Objective

We aim to describe baseline demographic and disease characteristics of this population, understand gaps in care, and gauge follow-through.

Study design

We performed a retrospective chart review of all new patients in the TU clinic at UCSF from February 2017 through January 2019. After approval from an institutional review board, demographic and clinical data were collected from medical records.

Results

39 new patients were seen in UCSF's TU clinic during a 23-month period. Our cohort included 20 patients with spina bifida and neurogenic bladder, 5 with bladder exstrophy, 3 with disorders of sexual development (DSD), 5 with obstructive uropathy, 2 with cloacal anomalies, and 1 patient each with calcinuria, reflux nephropathy, prune belly syndrome, and urachal cyst. Mean age of patients was 26 years, 63% were male, 88% spoke English, and 70% had public insurance. Patients lived an average of 94 miles from the clinic and had a mean zipcode-based household income of $70,110. There was an average of 19 months between the initial TU visit and the most recent prior urology visit. The median time since last creatinine as well as last renal ultrasound was 9 months. 19 (54%) patients warranted a total of 28 referrals to other providers at their initial visit, and 42% of these were obtained within 6 months.

Discussion

According to our demographic data, TU patients are likely to have public insurance, live far from the TU clinic, and come from low SES backgrounds. At initial presentation over half of patients warranted updated tests like creatinine and renal ultrasound. Furthermore, nearly two-thirds of patients required at least one referral to a different provider, suggesting a majority of these patients had unmet medical needs at the time of presentation to the TU clinic.

Conclusion

Our data indicate that new patients to the TU clinic often warrant additional workup, updated testing, and referrals to sub-specialty care as these needs are often unmet at the time of presentation. The etiology of this is unclear and it may be due to insurance difficulties, inability to identify an appropriate adult subspecialty provider or access to care issues. Further investigation into barriers to implementation of transitional care is needed to provide comprehensive management to this challenging patient population.

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.

Aim

To measure resilience and identify associated demographic and clinical factors in individuals with spina bifida.

Method

An anonymous survey was distributed via Facebook advertising to individuals with congenital urological conditions. Respondents 18 years or older with spina bifida were included in this study. Resilience was measured with the 10-item Connor-Davidson Resilience Scale. Mean resilience levels in the study population and a US general population sample were compared with Student's t-test. Multiple linear regression assessed demographic and clinical factors associated with resilience.

Results

The mean resilience score for participants (n=195; 49 males, 146 females; mean age 40y 2mo [SD 12y 7mo] range 18-74y) was 27.2 (SD 7.5), which differed from a mean of 31.8 (SD 5.4) for a US general population sample (p<0.01). Multiple linear regression demonstrated significant positive associations between resilience and older age (p=0.04), prior urological surgeries (p=0.03), higher household education (p<0.01), and higher physical function (p<0.01).

Interpretation

Resilience in individuals with spina bifida is moderately poor, relative to the general population, and is associated with certain demographic and clinical factors. As a modifiable construct with positive effects on quality of life, psychological well-being, and health-related behaviors, resilience is a promising target for intervention in individuals with spina bifida. What this paper adds Resilience in individuals with spina bifida is moderately poor. Resilience is lower in individuals with spina bifida than the general population. Resilience is associated with age, household education, physical function, and urological surgery.

Objective

To identify demographic and clinical characteristics associated with depression, anxiety, and social isolation among adults with spina bifida. We hypothesize that lower urinary tract dysfunction is associated with poor psychosocial outcomes.

Methods

An anonymous survey was distributed via Facebook advertising to individuals with congenital urologic conditions. Adults with spina bifida were included in our analysis. Lower urinary tract dysfunction was assessed with the Neurogenic Bladder Symptom Score. Depression, anxiety, and social isolation T-scores were measured using Patient-Reported Outcome Measures Information System instruments. A composite depression-anxiety score was calculated. Separate adjusted linear models assessed the association between lower urinary tract dysfunction and depression, anxiety, composite depression-anxiety, and social isolation.

Results

Around 195 participants were included. Rates of depression, anxiety, and social isolation were 48%, 47%, and 43%, respectively. Comorbid depression and anxiety occurred in 39% of subjects. On adjusted regression analysis, lower urinary tract dysfunction was associated with depression (P < 001), anxiety (P <.001), composite depression-anxiety (P <.001), and social isolation (P = .010).

Conclusion

Depression, anxiety, and social isolation are common in individuals with spina bifida relative to the general population, and associated with lower urinary tract dysfunction. Interventions focused on optimizing lower urinary tract symptoms and function, transition-age adults, group psychotherapy, and comorbid depression and anxiety may be of particular value in this population.

Discovery of scrotal swelling in a neonate can be a source of anxiety for parents, clinicians, and sonologists alike. This pictorial essay provides a focused review of commonly encountered scrotal masses and mimics specific to the neonatal setting. Although malignancy is a concern, it is very uncommon, as most neonatal scrotal masses are benign. Key discriminating features and management options are highlighted to improve the radiologist's ability to diagnose neonatal scrotal conditions and guide treatment decisions. Neonatal scrotal processes ranging from common to uncommon will be discussed.

Introduction

Congenital ventral penile curvature without hypospadias is often treated surgically in childhood. The history of untreated ventral curvature is unknown.

Objective

This study's aim was to examine the association of untreated ventral penile curvature with various sexual and psychosexual outcomes.

Study design

An electronic survey was advertised to men older than 18 years on Facebook. Men with possible ventral penile curvature identified themselves by choosing sketches that most closely represented their anatomy. Outcomes assessed included: Sexual Health Inventory for Men, difficulty of intercourse because of curvature, International Prostate Symptom Score, Penile Perception Score, psychosexual milestones, paternity, infertility, sitting to urinate, and the CDC HRQOL-4 module.

Results

Among participants, 81 out of 684 men (11.8%) reported untreated ventral penile curvature. Participants with self-reported curvature noted more difficulty with intercourse because of curvature (4.5 vs 4.9, p < 0.001), more unhealthy mental days (8.6 vs 6.2, p = 0.02), and increased dissatisfaction with penile self-perception compared with men without reported curvature (8.6 vs 9.5, p < 0.001).

Discussion

Men with possible untreated ventral curvature reported worse penile perception scores, more mentally unhealthy days, and increased difficulty with intercourse secondary to curvature compared with men without curvature. A limitation to this study is selection bias; responses collected were self-reported from survey volunteers. Additionally, the question identifying ventral penile curvature is not validated but performed well in pretesting. Most questions were from validated surveys, but some were modeled after validated surveys and/or contained high face validity types of questions.

Conclusion

Men with possible untreated ventral penile curvature reported more dissatisfaction with penile appearance, increased difficulty with intercourse, and more unhealthy mental days. Given high success rates, low complications, and improved outcomes after surgical correction of penile curvature reported in the literature, our results support correction of congenital penile curvature in childhood.
