RESUMO
PURPOSE: To retrospectively compare interpretations of Doppler ultrasound (US) in newborns with confirmed perinatal testicular torsion (PTT) by an experienced faculty (staff) pediatric radiologist (SPR), pediatric radiology fellow (PRF), pediatric urology fellow (PUF) and staff pediatric urologist (SPU). METHODS: US images of 27 consecutive males with PTT between May 2000 and July 2020 were retrieved. The testicles were classified as affected or non-affected by PTT. We performed a blinded comparison of interpretation by four assessors (SPR, PRF, PUF, SPU), with respect to the US features of PTT. Paired inter-rater agreement was calculated using Cohen's Kappa (κ) and overall agreement was assessed using Fleiss' kappa. RESULTS: Overall comparison using Fleiss' kappa found fair agreement for most features except testicular echogenicity and echogenic foci at interface for which there was poor agreement. Paired comparisons revealed better agreement between the SPR and PRF compared to the remaining two pairs, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents. CONCLUSION: This study highlights the need for focused training program for pediatric urologists to attain similar agreement as the radiologists, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents.

OBJECTIVE: To determine the current landscape of international medical volunteerism (IMV) in pediatric urology. METHODS: A questionnaire regarding IMV participation was distributed to Societies for Pediatric Urology members (SPU), pediatric urology fellows (PUFs), and pediatric urology fellowship program directors (PDs). Questions related to IMV interest, experience, and perceived barriers, as well as the importance of trainee participation. RESULTS: 98 of 733 SPU members queried responded; 62/98 (63%) having volunteered. There was no difference in gender, age, or years in practice between volunteers and non-volunteers (P >.05). Non-volunteers were generally interested in participating (26/36; 72%), with lack of time and knowledge of opportunities cited as limitations. 27/46 PUFs and 16/27 PDs submitted responses. 10/27 (37%) of PUFs have participated in IMV. The main perceived barrier to their participation was lack of protected time off. While 2 PUFs (7%) stated IMV was a mandatory component of fellowship, 11/27 (41%) of PUFs vs 2/16 (13%) of PDs believe IMV should be part of the curriculum (Pâ¯=â¯.11). PUFs and PDs similarly ranked importance of trainee IMV participation on Likert scale (median 73 vs 70, Pâ¯=â¯0.67). Volunteering SPU respondents ranked trainee participation higher than non-volunteers (median 80 vs 50, Pâ¯=â¯0.0004). CONCLUSION: While pediatric urology IMV opportunities exist, disseminating this information to interested parties and lack of time are barriers to participation. Amongst SPU members, there is a divide in attitudes regarding the importance of trainee participation. Trainees, however, strongly support IMV participation.

Background: Pages to house staff after hours, especially overnight, lead to interrupted sleep and fatigue the next day. Although some pages are urgent, others may not need an immediate response. In this study we aimed to identify unwarranted pages and to establish ways to reduce them. Methods: Over 2 months, all pages to the Department of Pediatric Urology at the Hospital for Sick Children in Toronto, Canada, during call hours were documented, including the assessment of the responding physicians of their medical necessity. After analyzing the reasons for inappropriate pages, we took several steps to try to reduce them without impairing patient care. One year later, pages were tracked again to evaluate the efficacy of our interventions. Results: In the initial measurement period, no calls from parents and approximately 50% of the in-hospital pages (15 of 36 pages from the wards, 27 of 49 pages from the emergency department, 17 of 31 pages requesting consultations, and 8 of 8 pages from the inhouse pharmacy and outside pharmacies) were considered medically urgent. The reasons for unwarranted pages were inconsistent parent teaching, lack of adequate triaging and prioritizing on the ward and lack of awareness of the structure of the on-call provisions among different services in the hospital. Several steps were taken to streamline the teaching of parents and nurses, standardize information, provide alternative means of communication within the hospital and restrict parents' access by phone to the urologist on call. One year later, the number of pages had decreased by 70%. Conclusion: Although physician coverage throughout the day and night is necessary for high-quality and safe patient care, communication with on-call physicians should be only for appropriate reasons. The provision of consistent teaching and alternative communication channels can improve patient care as well as decrease the number of after-hour pages.
Contexte: Les appels au personnel interne par téléavertisseur, surtout la nuit, perturbent le sommeil et entraînent de la fatigue le lendemain. Même si certains de ces appels sont urgents, d'autres ne nécessitent pas de réponse immédiate. Avec cette étude nous avons voulu identifier les appels par téléavertisseur qui sont injustifiés et trouver des façons d'en réduire le nombre. Méthodes: Sur une période 2 mois, nous avons documenté tous les appels par téléavertisseur adressés durant les heures de garde au service d'urologie pédiatrique de l'Hôpital SickKids de Toronto, au Canada, et demandé aux médecins y ayant répondu d'en évaluer le bien-fondé au plan médical. Après avoir analysé les raisons des appels jugés injustifiés, nous avons adopté plusieurs mesures pour en réduire le nombre sans compromettre les soins. Un an plus tard, nous avons de nouveau comptabilisé les appels par téléavertisseur pour mesurer l'efficacité de nos interventions. Résultats: Durant la période de mesure initiale, aucun appel des parents n'a été considéré médicalement urgent, tout comme environ 50 % des appels provenant de l'hôpital même (15 appels sur 36 des unités de soins, 27 appels sur 49 du service des urgences, 17 appels sur 31 pour des demandes de consultation et 8 appels sur 8 de la pharmacie de l'hôpital ou de pharmacies de l'extérieur). Les raisons des appels injustifiés étaient entre autres incohérence dans l'enseignement aux parents, triage et priorisation inadéquats à l'unité de soin et méconnaissance des différents services de l'hôpital quant à la structure et au fonctionnement du système de garde. Plusieurs mesures ont été prises pour simplifier l'enseignement aux parents et au personnel infirmier, standardiser l'information, fournir d'autres moyens de communication dans l'hôpital même et restreindre l'accès des parents à l'urologue de garde par téléphone. Un an plus tard, le nombre d'appels avait diminué de 70 %. Conclusion: Même si les médecins doivent être joignables jour et nuit pour assurer la qualité des soins et la sécurité des patients, les raisons de communiquer avec eux doivent être appropriées. Le rappel des consignes et le recours à d'autres canaux de communication peuvent améliorer les soins aux patients et réduire le nombre d'appels le soir et la nuit.

BACKGROUND: The clinical and economical value of routine submission of hernia sacs for pathological examination and scheduled clinic follow-ups after inguinal hernia and hydrocele repair has been questioned. Herein, we assessed the institutional variability in these routine practices. METHODS: We retrospectively reviewed patients who underwent unilateral or bilateral inguinal hernia and/or hydrocele repair, open or laparoscopically, at our institution from 2015 to 2018. RESULTS: 1181 patients were included (1074 inguinal hernias and 157 hydroceles). Of 531 specimens obtained from 446 (38%) patients, 515 (97%) were normal. 16 (3%) abnormal pathological findings included 7 with mesothelial hyperplasia, 5 with nonfunctional genital ductal remnants, 3 with ectopic adrenal cortical tissues, and 1 epidydimal structure which was not recognized at the time of surgery. 418 (35%) patients had scheduled clinic follow-ups 65 (IQR 46-94) days postoperatively. 44 (4%) patients with unexpected postoperative Emergency Department visits within 30â¯days of surgery were identified. Only one patient required inpatient treatment, and the rest did not require intervention or admission. The total direct cost of analyzing specimens during the study period was $30,798 CAD ($10,266/year). The average cost to detect a potentially significant finding was $1924.88/specimen and $2053.20/patient. CONCLUSIONS: Routine pathological examination of hernia sacs and scheduled clinic follow-ups were associated with significant costs and predominantly nonsignificant findings. They should therefore be reserved for patients with a high clinical suspicion of injuries/abnormalities or risk factors for potential complications. LEVEL OF EVIDENCE: This is a level III evidence study.

Small-sized kidney recipients (<20 kg) are at high risk of allograft vessel thrombosis. HP has been used to mitigate this risk but may infer an increase in bleeding risks. Therefore, we aim to determine whether HP is a safe means to prevent thrombosis in small kidney transplant patients by comparing those who have received HP and those who have NHP. A retrospective review of patients < 20 kg who underwent kidney transplant in our institution from 2000 to 2015 was performed. At our institution, unfractionated heparin 10 units/kg/hour is used as HP since 2009. Patients at increased risk of thrombosis (previous thrombosis, thrombophilia, nephrotic syndrome) and bleeding (therapeutic doses of heparin, diagnosis of coagulopathy) were excluded. Fifty-six patients were identified (HP n = 46; NHP n = 10). Baseline demographics were similar between HP and NHP. There was no statistical difference in frequency of transfusions, surgical re-exploration, or thrombotic events between HP and NHP. The HP group was more likely to have drop in Hb > 20 g/L (67.4% vs 30.0%, P = 0.038), and those who had drop in Hb > 20 g/L were more likely to also require pRBC transfusions (63.0% vs 20.0%, P = 0.017). Within the HP group, those who had bleeding complications had similar Hb levels as those who did not at baseline and post-transplant. Outcomes in the HP and NHP groups were no different with respect to thrombosis or significant bleeding complications requiring pRBC transfusions or surgical intervention. Future prospective studies are required to investigate the balance of preventing thrombosis and risks of pRBC transfusions for small-sized kidney recipients.

INTRODUCTION: Despite the widespread use of circumcision, there is little understanding regarding risk factors associated with its complications. This investigation assesses potential risk factors contributing to complications of circumcision. METHODS: A retrospective review of all males who underwent a neonatal circumcision in our institution's pediatric urology clinic between January 2015 and June 2017 was performed. Continuous variables were dichotomized to determine a clinically relevant cutoff value. Multivariate regression analyses were used to identify risk factors for primary outcomes (early/late complications) and secondary outcomes (emergency room [ER] visitation, return to operating room, post-circumcision communications). RESULTS: A total of 277 patients were identified. The mean age and weight were 28.4 days and 4.3 kg, respectively; 93.1% of cases were elective and 12.3% of patients had comorbidities. Circumcisions were performed using Mogen (61.4%) or Gomco clamps (39.6%) under local anesthesia. Overall, 35 patients experienced complications (12.6%). There were 18 patients (6.5%) with bleeding requiring sutures at time of circumcision. Twenty-six patients (9.4%) experienced long-term complications, with penile adhesions being the majority (84.6%). One (0.4%) of these patients had a Clavien-Dindo 3 complication requiring surgery for a skin bridge that could not be separated. One patient (0.4%) visited the ER due to postoperative bleeding from the circumcised area, which was managed conservatively. Multivariate regression analysis identified weight >5.1 kg as a risk factor for bleeding requiring sutures (odds ratio [OR] 4.145; 95% confidence interval [CI] 1.246-13.799) and long-term complications (OR 3.738; 95% CI 1.356-10.306). No risk factors were identified for other outcomes (return to operating room, ER visitation, post-circumcision email/telephone communications). CONCLUSIONS: This investigation of neonatal circumcision revealed that patients weighing >5.1 kg may be at higher risk of bleeding and long-term complications, such as adhesions.
RESUMO
PURPOSE: To determine whether there is a benefit to pre-emptive kidney transplantation in reducing surgical complications in pediatric population. METHODS: A retrospective review of kidney transplantations in our institution from 2000 to 2015 was performed. Intra- and postoperative complication rates and one-year graft survival were compared in their respective donor type groups (pre-emptive DD vs post-dialysis DD; pre-emptive LD vs post-dialysis LD). RESULTS: A total of 318 patients were identified (pre-emptive DD, n = 21; post-dialysis DD, n = 145; pre-emptive LD, n = 54; post-dialysis LD, n = 98). Between the DD groups, post-dialysis DD group was more likely to be female (P = 0.017). There was no difference in rates of intraoperative complications or graft loss (P = 0.365 and 1.000, respectively). Post-dialysis DD groups were more likely to have postoperative complications (9.5% vs 35.1%, P = 0.023), but no difference in complications with Clavien-Dindo grade 3 or higher was found (P = 0.130). Between the LD groups, post-dialysis LD group was more likely to be females (P = 0.017) and with intrinsic renal (non-urological/structural) ESRD etiology (P = 0.003). There was no difference in rates of intra-and postoperative complications or graft loss (P = 0.353, P = 0.605, and P = 0.616, respectively). CONCLUSIONS: Overall, there are similar perioperative complication rates between pediatric pre-emptive and post-dialysis kidney transplant recipients.

INTRODUCTION: Due to medical advances over the past three decades, the vast majority of children with spina bifida (SB) now survive into adulthood. As a result, there is a need to implement a well-defined urological transition process for these patients from the pediatric to adult environment. The objective of this study was to identify and analyze the current medical practices employed and the attitudes regarding transition by Canadian pediatric urologists caring for the SB population. METHODS: A survey consisting of 14 questions pertaining to physician demographics, current practice, and attitudes towards the transition process of SB patients was distributed at the 2015 annual Pediatric Urologists of Canada (PUC) conference. The survey respondents remained anonymous, and the data were collected and analyzed. RESULTS: A total of 28 surveys were collected from urologists across Canada (25 full-time pediatric, three also providing adult care), representing a >75% response rate. The transition process was suggested to begin at the age of 18 or older by 43% (12/28) of pediatric urologists. The majority, 86% (24/28), do not currently use a questionnaire or a checklist to determine transition readiness of patients. Forty-six percent (13/28) of pediatric urologists do not provide ongoing urological care to their patients after referral has been made to adult-centred care. In the province of Ontario, in which 39% (11/28) of the pediatric urologists practice, 82% (9/11) are full-time pediatric urologists and 78% (7/9) do not provide ongoing care to SB patients after the age of 18. CONCLUSIONS: A significant minority of Canadian pediatric urologists perceive that the transition process should begin at the age of 18 or older. As such, it can be inferred that transfer of care and transition are synonymous, not independent. Simplistically, this suggests that transition represents an event rather than a longitudinal process. The fact there is no defined ongoing urological care as a component of this process, suggests the potential for substandard quality of care after these patients graduate to the adult sector. Different provincial healthcare systems and funding plans may further hinder this transition of care by denying provider continuity based on reimbursement plans.
RESUMO
PURPOSE: Voiding cystourethrogram involves radiation exposure and is invasive. Several guidelines, including the 2011 AAP (American Academy of Pediatrics) guidelines, no longer recommend routine voiding cystourethrogram after the initial urinary tract infection in children. The recent trend in voiding cystourethrogram use remains largely unknown. We examined practice patterns of voiding cystourethrogram use and explored the impact of these guidelines in a single payer system in the past 8 years. MATERIALS AND METHODS: We identified all voiding cystourethrograms performed at a large pediatric referral center between January 2008 and December 2015. Patients 2 to 24 months old who underwent an initial voiding cystourethrogram for the diagnosis of a urinary tract infection in the first 6 months of 2009 and 2014 were identified. Medical records were retrospectively reviewed. RESULTS: During the study period 8,422 voiding cystourethrograms were performed and the annual number declined over time. In the pre-AAP and post-AAP cohorts 233 and 95 initial voiding cystourethrograms were performed, respectively. While there was no statistically significant difference in the vesicoureteral reflux detection rate between 2009 and 2014 (37.3% vs 43.0%, p = 0.45), there was a threefold increase in high grade vesicoureteral reflux in 2014 (2.6% vs 8.4%, p = 0.03). CONCLUSIONS: A clear trend toward fewer voiding cystourethrograms was noted at our institution. This decrease started before 2011 and cannot be attributed to the AAP guidelines alone. While most detected vesicoureteral reflux remains low grade, there was a greater detection rate of high grade vesicoureteral reflux in 2014 compared to 2009. This may reflect a favorable impact of a more selective approach to obtaining voiding cystourethrograms.

BACKGROUND AND OBJECTIVES: There is a limited role for ultrasound in the management of an undescended testicle (UDT). We hypothesized that ultrasound remains overused by referring physicians. Our goal was to characterize the trends, patterns, and impact of ultrasound use for UDT and to reaffirm its limited diagnostic value for this indication. METHODS: The records of boys aged 0 to 18 years with UDT in Ontario, Canada, between 2000 and 2011 were reviewed by using health administrative data housed at the Institute for Clinical and Evaluative Sciences (ICES). A second review of boys referred to our institution with UDT between 2007 and 2011 was conducted to complement the health administrative data. Trends in frequency, distribution, and costs of ultrasound use were assessed. Time delays between diagnosis and definitive management were compared between the ultrasound and non-ultrasound groups. Using our institutional data, we analyzed demographic patterns of ultrasound use and compared its diagnostic accuracy by using surgical findings as the gold standard. RESULTS: Ultrasound was used in 33.5% of provincial referrals and 50% of institutional referrals. Children who underwent ultrasound experienced an approximate 3-month delay in definitive surgical management. Ultrasound correctly predicted physical examination findings in only 54% of patients. Physicians in community practice, and those with fewer years in practice, were more likely to order ultrasound. CONCLUSIONS: Ultrasound has limited value for the management of UDT but remains widely overused, with an increasing trend over time. This practice has negative implications for access to care and cost-containment. Widespread educational efforts should be undertaken, targeting current and future referring physicians.

BACKGROUND/PURPOSE: Indirect expenses for accessing health care may place significant fiscal strain on Canadian families. Telemedicine alternatives, using email, telephone, and video conferencing, can mitigate such financial burdens by reducing travel and related costs. Our objectives were to assess costs that families incur visiting an outpatient pediatric surgical clinic, and family attitudes toward telemedicine alternatives. METHODS: A survey was offered pre-consult to all families who attended pediatric urology and general surgery outpatient clinics over a three-month period. RESULTS: A total of 1032 of 1574 families screened participated (66.0%). Less than half (18.5%) of participants traveled over 200 km, and 32.9% spent over 4 hours in transit, round-trip. The proportion of participants who spent over $50 on travel and ancillary expenses was 33.0%. In 74.0% of families, 1 or more adults missed work. The proportion of families who perceived costs as somewhat high or high was 29.1%. Perceived cost was positively correlated to distance traveled, money spent, and missed work (p<0.01). Most were comfortable with medical communication using technology; and 34.3%-42.7% would avoid an in-person clinic visit utilizing email, telephone, and video conferencing. Higher perceived cost (p<0.001) and distance traveled (p<0.01) were only weakly associated with greater willingness to substitute a clinic visit with video conferencing. CONCLUSIONS: Many families face high costs related to routine outpatient clinical visits, and there is a substantial willingness by them to access telemedicine alternatives, rather than the traditional face-to-face clinical visit.

OBJECTIVES: To compare the operative time, outcome, complications, and patient costs between laparoscopic varicocele ligation (LVL) and subinguinal microscopic varicocelectomy (SMV) in two patient cohorts. Varicocele therapy is a controversial issue, with no single approach adopted as the best therapeutic option. LVL has been considered more expensive and of no proven benefit compared with SMV. METHODS: We compared two groups of patients who underwent surgical correction of varicocele at our institutions during a 6-year period. Group 1 included postpubertal adolescents who underwent LVL and group 2 included adults seen at an infertility practice who underwent SMV. The outcome measures selected included operative time, direct hospital costs to the patient, and negative outcomes. RESULTS: We identified a total of 72 patients, 36 (mean age 13.8 years) in group 1 and 36 (mean age 34.1 years) in group 2. Group 1 had no persistent or recurrent varicoceles compared with 4 patients in group 2. Three men in group 2 required emergency room evaluation and no patient did so in group 1. No hydroceles developed in group 2, but three developed in group 1. CONCLUSIONS: LVL resulted in shorter operative times and fewer negative outcomes compared with SMV. This translated into lower direct patient costs for LVL. For those who have mastered laparoscopic techniques, LVL should be considered a safe, cost-effective option in the correction of varicoceles.
