RESUMEN
OBJECTIVE: To decrease the number of inappropriate pages after-hours by 50%. METHODS: Over 9 weeks, after-hours pages to the on-call resident at University of Minnesota Department of Urology were documented. Pages were deemed "appropriate" or "inappropriate" by 3 independent reviewers. The source of each page was reviewed and after several plan-do-study-act (PDSA) cycles, 3 separate interventions were created, directed at floor nursing, patient phone calls, and the call triage center. After a 6-week implementation period, data were re-collected for 9 weeks. Descriptive statistics were generated, and a Mann-Whitney U test was used to compare inappropriate pages pre- and post- interventions. RESULTS: In phase I, 48 shifts were recorded. The mean number of pages per shift was 8.9 (range 1-27), with 52.7% of pages considered "inappropriate." Most pages came from the wards (48.9%) followed by the emergency department (20.4%), patient phone calls (19.4%), and the call center (2.6%). From these domains, the call center had the highest proportion of inappropriate pages (90.9%). In phase II, 39 shifts were recorded. The mean number of pages per shift decreased to 6.0 (range 1-20), and inappropriate pages per shift decreased by 68.4%, (P <.0001). CONCLUSION: By improving communication to nurses, patients, and call center personnel, inappropriate after-hours pages decreased by 68.4%-exceeding our aim. Future studies are needed to assess if the impact was sustainable over time.
RESUMEN
BACKGROUND: Learning health networks (LHN) are consortia of institutions that collaborate and embrace the elements of the learning health system (LHS), including quality improvement, education, research, and stakeholder involvement. Their ultimate goal is rapid information dissemination in clinical care. Pediatric surgical specialties perform unique yet high-impact procedures that could benefit from LHN, thereby improving surgical outcomes and care through LHS approaches. Consequently, health system leaders should be aware of LHN and their importance in enhancing surgical care and improving outcomes. This scoping review aims to map and characterize the existing LHN applied in pediatric surgical specialties. METHODS: A systematic literature search was performed on Medline, EMBASE, and Scopus up to June 2022, with an update search conducted in May 2023. Additionally, Google Scholar, ProQuest and inquiry from topic experts were used for cross-referencing relevant review articles to identify grey literature. This scoping review was conducted and reported according to the PRISMA-scoping review extension. RESULTS: A total of 56 publications for 19 LHN were identified and included in this scoping review. Out of 19 identified LHN in pediatric surgical specialties, 18 were organized in North America. Eight of the networks are related to pediatric general surgery and another eight were related to pediatric transplantation. The 16 out of 19 LHN were initiated after 2001. To date, only eight of the LHNs generated reports of comparative improved outcomes. CONCLUSION: This scoping review provides an overview of the available LHNs in pediatric surgical specialties. Over the past decade, several pediatric surgical specialties have embraced the principles of learning health systems, forming inter-institutional collaborations that utilize information technology to generate big data on patient-level clinical information, engage in quality improvement cycles, adopt evidence-based practices, and actively involve patients and stakeholders. LEVEL OF EVIDENCE: IV.

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.

OBJECTIVES: To determine the risk factors that affect surgical outcomes for pediatric pyeloplasty, and whether this may be related to the choice of operative approach. METHODS: A retrospective cohort study was performed to evaluate clinicodemographic and operative characteristics of children undergoing dismemberment pyeloplasty by 2 senior pediatric urologists in our tertiary institution between Jan 2008 - Dec 2017. Outcomes included overall complications, re-stenosis, and revision pyeloplasty based on clinic-radiological parameters. Bivariate analysis with Chi-square and Mann-Whitney U test followed by multivariate logistic regression with backward likelihood analysis determined an adjusted effect estimate of the identified significant indicators for inferior peri-operative outcomes related to management. RESULTS: A total of 185 (93 open, 92 Laparoscopic) cases with an average follow-up of 31.3±27.4 months were analyzed. Complications occurred in 21 (11.4%) patients. 12 (6.5%) experienced recurrent UPJ obstruction with 10 (5.4%) undergoing redo-pyeloplasty. Of these, 9 were performed open and 1 laparoscopically. Multivariate logistic regression identified open pyeloplasty as an independent predictor for overall complications (HR 3.29, 95%CI 1.14, 9.51), recurrent UPJ obstruction (HR 49.8, 95%CI 3.09, 803.2) and redo-pyeloplasty (HR 9.75, 95%CI 1.21, 78.6) compared to a laparoscopic approach. Missed crossing vessels were identified in seven redo-cases, which all were from prior open pyeloplasty. CONCLUSIONS: An initial open approach was identified as an independent predictor of future complications due to a higher incidence missed crossing vessels at initial repair. Surgeons need to remain especially mindful of this phenomenon when working in a confined open field.
RESUMEN
BACKGROUND/OBJECTIVE: This study aims to understand perspectives on routine pathological examination of hernia sacs following pediatric inguinal hernia and hydrocele repair among Canadian pediatric urologists, surgeons, and pathologists. STUDY DESIGN: All active members of Pediatric Urologists of Canada (PUC), Canadian Association of Pediatric Surgeons (CAPS), and the divisional heads of anatomical pathology at the Canadian children's hospitals (AP) were invited to participate between June 2019 and January 2021 in an anonymous multiple-choice-based questionnaire. RESULTS: The response rates were 71% from PUC (24/34), 20% from CAPS (25/130), and 64% from AP (7/11). The majority of the surgeons (PUC:54%, CAPS:68%) did not routinely send hernia sacs for pathological examination after inguinal hernia repair. Most felt there was a little value in such examination (PUC:96%, CAPS:72%). Among those who submit hernia sacs, the majority did not receive reports that were clinically significant impacting patient management (PUC:82%, CAPS:50%). On the other hand, the pathologists had mixed opinion on the value of examining hernia sacs. Most of them only did gross examination (86%), unless requested by surgeons or concerning features were noted on gross examination. The majority have found clinically meaningful abnormal findings (71%), including vas deferens and portions of the spermatic cord. DISCUSSION: Currently, there are no evidence-based clinical guidelines on pathological assessment of hernia sacs after pediatric inguinal hernia and hydrocele repair. Instead of making it mandatory, future guidelines should highlight specimens that should be submitted for further investigations (e.g., challenging cases where inadvertent surgical injuries might have occurred). Future studies should also address whether patients who may be at higher risk of having clinically significant pathology can be identified pre- or perioperatively to more efficiently triage specimens that would benefit from pathological examination. Limitation of the study includes low response rate from the CAPS members during the COVID-19 pandemic. CONCLUSIONS: While most of the pediatric urologists and surgeons felt there is a little value of pathological examination of hernia sacs following inguinal hernia and hydrocele repair, half of the anatomical pathologists felt there is value. Future studies should aim to establish evidence-based clinical guidelines taking stakeholders perspectives into consideration.

BACKGROUND: There are several databases across the world that collect pediatric KT data. We compare the hospitalization outcomes for pediatric KT recipients from a large Canadian transplant center (SickKids database; The Hospital for Sick Children Kidney Transplantation Institutional Database), United States (NAPRTCS), and Europe (CERTAIN registry). METHODS: An institutional retrospective review of KT was performed between 2000 and 2015. Baseline characteristics, duration of initial hospitalization/readmission at 1-5 and 6- to 11-month posttransplant, and 1-year graft survival data were collected. Corresponding data from the NAPRTCS 2014 Annual Transplant Report and CERTAIN registry were compared. RESULTS: Posttransplant, patients from NAPRTCS had the shortest duration of hospitalization within the first month (10.4 days, SE 0.2), followed by SickKids (20.3 days, SE 0.7) and CERTAIN (25.5 days, SE 0.7). For both living and deceased donor populations, patients from SickKids were most likely to be hospitalized at 1- to 5-month posttransplant (82.4% [89/108]; 72.1% [98/136]), followed by Europe (52.1% [198/380]; 61.6% [501/813]) and United States (45.4% [2379/5241]; 51.4% [2517/4896]). Patients from Europe were most likely to be hospitalized at 6- to 12-month posttransplant (42.1% [160/380]; 51.7% [420/813]), followed by SickKids (35.2% [38/108]; 37.5% [51/136]) and United States (28.3% [1387/4901]; 31.6% [1411/4465]). Across all databases, the most commonly addressed issues during readmissions were infectious complications. CONCLUSION: The differences observed in this investigation may reflect the local reimbursement models, resources for outpatient management, and practice variations across a large Canadian transplant center, United States, and European countries.

OBJECTIVE: To assess the role native nephrectomy (NN) in hypertension-related outcomes for pediatric patients undergoing renal transplantation (RT). METHODS: Renal transplants (RT) performed at our institution between 2006 and 2015 were reviewed. RT recipients who underwent NN were compared to those who did not. Primary outcomes were hypertension-related: use/number of medications pre-/post-transplant and hypertension-related readmissions. Secondary outcomes were 1-year outcomes of: readmissions, eGFR, Clavien-Dindo classification ≥ 3 complications, and graft loss. RESULTS: 135 patients were evaluated. 24 underwent NN (Group 1) and 111 did not (Group 2). Baseline characteristics were similar between Groups 1 and 2. The majority of NN indications were hypertension (10/39 kidneys) and proteinuria (12/39 kidneys). There were no differences in use/number of anti-hypertensive medications pre- or post-transplant. However, between Group 2 and subgroup of patients who underwent NN for hypertension, a significant difference was seen in medication use/numbers but not post-transplant. Number of readmissions due to hypertension was similar (7.2% vs. 12.5%). The only difference in secondary outcomes was higher readmission rates with bacterial infections for group 1 (45.8% vs. 23.4%, p = 0.041). CONCLUSION: NN, when offered to patients at higher risk of post-RT hypertension, may allow high-risk patients to achieve similar hypertension outcomes as those at lower risk.

BACKGROUND: Use of prophylactic antibiotics after stented hypospadias repair is very common, but most research has not identified any clinical benefits of this practice. Only one study has found that postoperative prophylaxis reduces symptomatic urinary tract infections (UTIs). Data from the same trial suggested that prophylaxis may also reduce urethroplasty complications. No studies on this subject have been placebo-controlled. OBJECTIVE: We performed a randomized, double-blind, placebo-controlled study to evaluate the effect of postoperative prophylactic antibiotics on the incidence of infection or urethroplasty complications after stented repair of midshaft-to-distal hypospadias. STUDY DESIGN: Boys were eligible for this multicenter trial if they had a primary, single-stage repair of mid-to-distal hypospadias with placement of an open-drainage urethral stent for an intended duration of 5-10 days. Participants were randomized in a double-blind fashion to receive oral trimethoprim-sulfamethoxazole or placebo twice daily for 10 days postoperatively. The primary outcome was a composite of symptomatic UTI, surgical site infection (SSI), and urethroplasty complications, including urethrocutaneous fistula, meatal stenosis, and dehiscence. Secondary outcomes included each component of the primary outcome as well as acute adverse drug reactions (ADRs) and C. difficile colitis. RESULTS: Infection or urethroplasty complications occurred in 10 of 45 boys (22%) assigned to receive antibiotic prophylaxis as compared with 5 of 48 (10%) who received placebo (relative risk [RR], 2.1; 95% confidence interval [CI], 0.8 to 5.8; p = 0.16). There were no significant differences between groups in symptomatic UTIs, SSIs, or any urethroplasty complications. Mild ADRs occurred in 3 of 45 boys (7%) assigned to antibiotics as compared with 5 of 48 (10%) given placebo (RR, 0.6; 95% CI, 0.2 to 2.5; p = 0.72). There were no moderate-to-severe ADRs, and no patients developed C. difficile colitis. CONCLUSIONS: In this placebo-controlled trial of 93 patients, prophylactic antibiotics were not found to reduce infection or urethroplasty complications after stented mid-to-distal hypospadias repair. The study did not reach its desired sample size and was therefore underpowered to independently support a conclusion that prophylaxis is not beneficial. However, the result is consistent with most prior research on this subject. GOV IDENTIFIER: NCT02096159.

INTRODUCTION: This study aimed to evaluate the efficacy and safety of Hyperbaric Oxygen Therapy (HBOT) use in hypospadias repair through systematic review and meta-analysis of comparative studies. METHODS: A systematic literature search was performed in May 2021. Comparative studies assessing the surgical outcome of hypospadias repair between control versus HBOT utilization were identified and evaluated according to Cochrane collaboration recommendations. The assessed outcome includes hypospadias repair failures and graft failure for staged repair using a buccal graft. Relative risk with corresponding 95% confidence intervals (CI) were extrapolated. A random-effect model was used to generate pooled effect estimates. Heterogeneity and inter-study variability were assessed using Chi-square and I-square. Subgroup analysis was performed according to primary repair versus redo-hypospadias with buccal graft. PROSPERO registration (CRD42021251423). RESULTS: Five comparative studies with 576 cases (301 HBOT versus 275 controls) were included. Overall pooled effect estimates showed that the HBOT group has significantly lesser hypospadias repair failure (RR 0.52, 95%CI 0.37, 0.72). Subgroup analysis on the use of HBOT for graft take showed lesser graft failure compared to the control group (RR 0.20, 95% CI 0.05, 0.75), while the use of HBOT for primary and redo single staged hypospadias repair showed lesser complication rate (RR 0.56, 95%CI 0.40, 0.78). Based on ROBINS-I assessment, all included comparative studies are determined to be of serious risk of bias mainly due to presence of confounding. CONCLUSION: The currently available low-quality of evidence suggests that compared to control groups, HBOT as an adjunctive intervention to complicated hypospadias repair was able to reduce surgical outcome failure and graft failure rates.

Neonatal circumcision (NNC) is the most frequently performed surgical procedure worldwide and is generally considered safe in Western societies. Deaths attributed to NNC are seldom reported and are mostly explained by lack of adherence to medical standards. We reviewed our emergency department database for circumcision-related emergency admissions. During 2000-2013, 19 previously healthy neonates were admitted for acute complications after circumcision. Four were admitted for bleeding, with hemophilia identified in two cases and von Willebrand disease in one. Eight boys required emergency surgery, three for severe bleeding. Four boys with amputation of the glans underwent immediate surgical reconstruction. One infant was taken to the operating room to remove an obstructing Plastibell ring. Seven boys were admitted to the intensive care unit with severe bleeding or sepsis, three of whom ultimately progressed to hemorrhagic or septic shock. Two of these children died of their complications. We estimate that the annual incidence of severe complications requiring hospitalization after NNC in the Greater Toronto Area was approximately 0.01%, and the incidence of fatalities over the 14-yr review period was approximately 0.0012%. Our results indicate that the risk of serious complications and death as a result of NNC is greater than generally assumed.

OBJECTIVES: Peritoneal dialysis (PD) is an option for ultrafiltration for patients with end-stage renal disease. Once placed, PD catheters may malfunction often due to omental wrapping. Omental procedures such as omentectomy and omentopexy may reduce this risk. This investigation aims to perform a systematic review and meta-analysis of the literature on the role of omental procedures on PD catheter insertions. METHODS: Following protocol registration on PROSPERO (CRD42020218950), a systematic review was performed in accordance with the Cochrane Collaboration. A literature search was performed in February 2021 across Medline, EMBASE, Scopus, and Cochrane Library. Records with patients who underwent PD catheter insertion with and without omental manipulation were included. The records underwent screening, full-text review, and data extraction. Study qualities were assessed using RoBINS-I and RoB2. Effect estimates were extracted as risk ratios and corresponding 95% confidence intervals (CI) were pooled using inverse variance method with random-effect model. RESULTS: Of 510 records identified, 15 studies were included in the meta-analysis (1 RCT, 2 prospective, 12 retrospective). With omental procedures, there was decreased the likelihood of failure requiring removal of PD catheter (RR 0.47, 95% CI 0.38, 0.58) and PD catheter obstruction (RR 0.23, 95% CI 0.14, 0.39); there was no difference in likelihood of catheter malposition or migration (RR 0.87, 95% CI 0.23, 3.29) or peritonitis (RR 0.74, 95% CI 0.40, 1.35). CONCLUSION: Based on the current low to moderate quality of evidence, omental manipulation at the time of PD catheter insertion confers benefits of decreased obstruction and failure requiring removal.

BACKGROUND: Perinatal testicular torsion (PTT) is a catastrophic event that occurs in utero or up to 30 days postnatally, with testicular loss being the most common outcome. OBJECTIVE: To assess clinical evaluation, surgical management and clinical outcomes in patients with PTT in a quaternary referral pediatric center, to determine testicular salvageability and propose future management options. METHODS: We retrospectively reviewed a cohort of males born outside the quaternary center with a diagnosis of PTT, from May 2000 to July 2020. Data collection included mode of delivery, gestational age, birth weight, testicular examination at birth, clinical presentation, ultrasound results at diagnosis, surgical management and findings, perioperative complications, and follow-up. RESULTS: 62 patients, including 2 patients with bilateral asynchronous PTT, were identified. Median (IQR) gestational age and birth weight were 39 (38-39.4) weeks and 3.4 (3.1-3.72) kg, respectively. Abnormal testicular examination at birth was found in 69% (Table 1). Doppler ultrasound was performed in all but 1 patient. 59 patients underwent surgery, 21 within 4 h, with bilateral exploration in 44 cases. Affected and non-affected testicles were explored in 76% and 98% of cases, respectively. 3 "nubbins" were found, of which 2 were excised. 3 nonsurgical complications were identified. During a median (IQR) follow-up of 3 (3-3) months, 63 testicles were removed or found to be non-functional, with compensatory hypertrophy in 38% of patients. CONCLUSION: Given that 3% of our patients presented with asynchronous bilateral PTT, as well as the safety of general anesthesia in a referral pediatric hospital, early bilateral scrotal exploration of PTT is recommended. LEVEL OF EVIDENCE: IV.
