Use of Low-Dose Computed Tomography in Children With Nephrolithiasis: An Analysis From 2 Tertiary Pediatric Centers.

INTRODUCTION: Although ultrasound (US) is the preferred first-line imaging for pediatric nephrolithiasis, CT may be necessary in cases of a nondiagnostic US or when US in not available. Utilization of dose reduction strategies in children undergoing CT for nephrolithiasis is not well described. We compared use of low-dose CT (LDCT) in children presenting to 2 pediatric centers. METHODS: We performed a retrospective chart review of children ≤ 17 years of age presenting with suspected nephrolithiasis to 2 tertiary children's hospitals, inclusive of those referred to these centers from nonpediatric facilities between 2013 and 2019. Children were included with an index CT scan from either the pediatric or referring center while those who had prior documented CT for nephrolithiasis within the study period or missing radiation dose assessment were excluded. The primary outcome was LDCT as defined as radiation dose < 3 mGy. The primary comparator was pediatric vs outside referral center. Exploratory analysis evaluated other factors associated with LDCT, including radiation dosage as a continuous variable. RESULTS: A total of 155 individuals met inclusion criteria, with 126 (81.3%) receiving standard dose and 29 (18.7%) receiving LDCT. Pediatric facilities were more likely to utilize LDCT as compared to referral centers (P < .05). Older age and higher BMI were also found to be associated with increased radiation dose exposure. CONCLUSIONS: Pediatric facilities utilized LDCT more frequently, although age and BMI may also influence imaging choices. An understanding of the factors associated with dose reduction in CT will impact future efforts to explore optimum imaging stewardship in pediatric nephrolithiasis.

Urologists' Perceptions and Practices Related to Patient Smoking and Cessation: A National Assessment From the 2021 American Urological Association Census.

OBJECTIVE: To assess urologists' perceptions and practices related to smoking and smoking cessation. MATERIALS AND METHODS: Six survey questions were designed to assess beliefs, practices, and determinants related to tobacco use assessment and treatment (TUAT) in outpatient urology clinics. These questions were included in an annual census survey (2021) offered to all practicing urologists. Responses were weighted to represent the practicing US population of nonpediatric urologists (N = 12,852). The primary outcome was affirmative responses to the question, "Do you agree it is important for urologists to screen for and provide smoking cessation treatment to patients in the outpatient clinic?" Practice patterns, perceptions, and opinions of optimal care delivery were assessed. RESULTS: In total, 98% of urologists agreed (27%) or strongly agreed (71%) that cigarette smoking is a significant contributor to urologic disease. However, only 58% agreed that TUAT is important in urology clinics. Most urologists (61%) advise patients who smoke to quit but do not provide additional cessation counseling or medications or arrange follow-up. The most frequently identified barriers to TUAT were lack of time (70%), perceptions that patients are unwilling to quit (44%), and lack of comfort prescribing cessation medications (42%). Additionally, 72% of respondents stated that urologists should provide a recommendation to quit and refer patients for cessation support. CONCLUSION: TUAT does not routinely occur in an evidence-based fashion in outpatient urology clinics. Addressing established barriers and facilitating these practices with multilevel implementation strategies can promote tobacco treatment and improve outcomes for patients with urologic disease.

The R Frank Jones Urology Interest Group: An Intentional and Strategic Pipeline Program to Increase Diversity in Urology.

To address the low numbers of urologists who are ethnically and racially underrepresented in medicine (URiM), the nonprofit organization Urology Unbound developed the R. Frank Jones Urology Interest Group (RFJUIG), a pipeline program that provides mentorship, research opportunities, and professional development for URiM students. Students complete a questionnaire as part of the registration process for the RFJUIG. This questionnaire collects demographic information and asks about their experience pursuing urology and goals for participation in the program. At the end of 2020, 66 students (60% Black and 21% Latinx) were registered members of the RFJUIG. The majority of the members identify as immigrants or first-generation Americans, originating from at least 10 different countries. While most members reported early interest in the field, only 11% had a friend or family with a connection to urology. In the 2021 urology match, 31 of 39 applicant members successfully matched into a urology residency position. Intentional and strategic pipeline programs increase the recruitment of URiMs in urology. Thus far, the RFJUIG successfully provided 79% of its applicant members with the tools needed to successfully match into urology.

Use of fibrin glue to treat a persistent pneumothorax with bronchopleural fistula.

PURPOSE: A case of spontaneous pneumothorax with a subsequent bronchopleural fistula (BPF) treated with endoscopically administered fibrin glue is presented. SUMMARY: A 76-year-old white man with a history of a benign lung mass and chronic obstructive pulmonary disease was admitted to the hospital with right-sided, anterior, pleuritic chest pain for the past three days and shortness of breath at rest, which worsened during exertion. Initial chest radiograph revealed a right 95% spontaneous tension pneumothorax. A chest tube was immediately placed in the right pleural space, resulting in reinflation of the lung. However, air leaks continued to be present, requiring the need for surgical intervention. The patient required both coronary artery bypass graft surgery and right blebectomy with pleurodesis. Postsurgery, the patient required two pleural chest tubes for the persistence of a BPF. A critical care clinical pharmacist was consulted regarding potential use of an endoscopic fibrin seal. Fiberoptic bronchoscopy was performed, and diffuse bronchiectasis was noted in all right lower respiratory airways. The day after the fibrin sealant was administered, one of the pleural chest tubes was removed because the air leak was significantly reduced in size. The patient was discharged home two days later with a Heimlich chest valve. One week postdischarge, a chest radiograph revealed no pneumothorax. CONCLUSION: Use of a fibrin sealant injected through a fiberoptic bronchoscope was effective in reducing an air leak associated with a spontaneous pneumothorax and subsequent BPF.
