RESUMO
PURPOSE: We describe long-term outcomes, including UTIs and need for reimplantation, after ureterovesicostomy (UV) as a lasting surgical procedure for children with primary obstructive megaureter (POM). MATERIALS AND METHODS: Children referred to our institution between 2016 and 2023 who underwent refluxing UV were analyzed. POM was defined as hydroureteronephrosis with distal ureteral dilatation > 7 mm and a negative workup for other etiologies of hydronephrosis. We assessed for surgical outcomes, complications, rate of UTI, and improvement in upper tract dilatation. Statistical analyses assessed for change in hydronephrosis metrics over follow-up. RESULTS: Among 183 patients diagnosed with POM, 47 (24%) underwent UV. Median age of presentation, surgery, and follow-up was 2, 9, and 43 months, respectively. A total of 7 patients developed 30-day complications: Clavien-Dindo grade 1 in 2 (transient urinary retention) and grade 2 in 5 (UTIs). During monitoring 14 (30%) developed UTIs and 7 (15%) required ureteral reimplant or UV takedown. After surgery there was a significant decrease in the proportion of patients with high-grade hydronephrosis, anteroposterior renal pelvis diameter, and maximum ureteral dilatation. CONCLUSIONS: Refluxing UV is a safe alternative to cutaneous diversion in POM. Most patients had improvement in upper tract dilatation with an acceptable short-term complication rate and need for reoperation (in comparison to routine later reimplantation). Our experience suggests that monitoring alone after UV is feasible, and that selective subsequent reconstruction is a reasonable strategy.

OBJECTIVE: We sought to determine the effect of secondary management strategies in addition to urotherapy on bowel bladder dysfunction outcomes. STUDY DESIGN: The review protocol was prospectively registered (CRD42023422168). MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, and Scopus (database initiation until June 2023) were searched. Comparative studies of secondary management strategies vs conventional urotherapy alone were included. Two authors independently screened titles, abstracts, and reviewed full-text articles. Two authors extracted data related to study characteristics, methodology, subjects, and results. RESULTS: In this systematic review and meta-analysis of 18 studies and 1228 children, secondary management strategies (home-based education, biofeedback, and physical therapy) were associated with reduced symptom burden, fewer recurrent urinary tract infections, and improved uroflowmetry findings than children treated solely with urotherapy for conservative management. CONCLUSIONS: Although there is significant reporting heterogeneity, secondary conservative management strategies such as home education, biofeedback or cognitive behavioral therapy, and physiotherapy-based education are associated with less urinary incontinence, fewer infections, and fewer abnormal uroflowmetry findings.
RESUMO
Urinary tract dilation (UTD), which refers to the abnormal dilation of the urinary collection system, is the most common finding on prenatal ultrasound and presents with varying severity, presentation, etiology, and prognosis. Prenatal classification and risk stratification aim to prevent postnatal complications, such as urinary tract infections and further kidney dysfunction. Parents expecting a child with UTD should be counseled by a multidisciplinary team consisting of maternal-fetal medicine specialists, and pediatric urology and nephrology providers. This review summarizes the key points in the diagnostic evaluation and management during the prenatal and initial postnatal period, focusing on the information that should be provided to future parents. We address frequently asked parental questions and concerns that our multidisciplinary clinical practice faces.

PURPOSE: This study evaluates the inter-rater agreements of both the Glans-Urethral Meatus-Shaft (GMS) hypospadias score and Hypospadias Objective Penile Evaluation (HOPE) score, aiming to standardize disease classification for consistent agreement in clinically relevant characteristics of hypospadias. METHODS: Photos of hypospadias in children were collected from two separate institutions. Three raters scored the photos using GMS and HOPE, excluding penile torsion and curvature assessment in HOPE due to photo limitations. RESULTS: A total of 528 photos were included. With GMS, Fleiss' multi-rater kappa showed an agreement of 0.745 for glans-urethral plate, 0.869 for meatus, and 0.745 for shaft. For HOPE scores, the agreements were 0.888 for position of meatus, 0.669 for shape of meatus, 0.730 for shape of glans, and 0.708 for the shape of the skin. The lower agreement in the shape of the meatus evaluation may be attributed to the lack of a quantitative classification method in HOPE. Experts rely on their subjective judgment based on the provided example photos and their index patient. CONCLUSIONS: While there is high agreement among experts when evaluating hypospadias using the GMS and HOPE scoring criteria, only the position of the meatus achieved nearly perfect agreement highlighting that the current scoring systems entail a subjective element in disease classification.

Introduction: Congenital penile curvature (PC), often concomitant with hypospadias, poses challenges in urology. Surgical correction techniques, including plication and corporotomy, lack standardized guidelines. This study aims to address the paucity of high-level evidence by comprehensively reviewing the outcomes of PC correction procedures in patients with and without hypospadias. This will inform clinical decision-making and provide insights for future research and meta-analyses. Methods: We conducted this scoping review in accordance with the JBI Manual for Evidence Synthesis and PRISMA-ScR guidelines. An extensive literature search was performed and comparative studies published in English up to June 2023 were included. The studies were divided into three categories: PC without hypospadias, PC with hypospadias, and studies comparing two or more materials for covering the ventral corporotomy. Data extraction comprised author details, patient characteristics, study design, interventions, outcomes, and complications. Methodological quality was assessed using the Newcastle-Ottawa Scale. Results: Forty-two studies were included in the review, which collectively comprised 3180 patients. Thirteen comparative studies reported the outcomes of surgery for congenital PC without hypospadias, 22 studies compared different techniques of PC correction in patients with hypospadias and 7 studies compared the type of materials for coverage following ventral corporotomy. In cases of PC without hypospadias, the most commonly reported surgery was the Nesbit's plication. For PC with hypospadias correction, the results of ventral corporotomy were superior to that of dorsal plication in most of the studies. The two-stage repair had better results when compared to the one-stage repair for patients with perineo-scrotal hypospadias. In studies comparing materials for coverage of ventral corporotomy, the tunica vaginalis flap or graft was utilized most commonly. The majority of the studies reported a success rate ranging from 85% to 100%. The methodological quality was high in all but four studies. Conclusion: Plication procedures are generally preferred for PC without hypospadias, but they result in penile shortening. For those with hypospadias, corporotomy is associated with superior outcomes than plication, especially for those with severe curvature and redo procedures. For ventral corporotomy coverage, the tunica vaginalis flap or graft is the most commonly reported tissue in the literature.

INTRODUCTION: Initiated in 2009, the U.S. News & World Report (USNWR) pediatric urology rankings aim to guide patients and families towards high-quality urologic care. Despite this, the pediatric urology community remains divided, with significant debate over the rankings' accuracy, utility, and potential for misleading information. While some professionals argue for a collective opt-out from these rankings, citing these concerns, others highlight their positive impact on patient care, hospital benchmarking, and financial support. OBJECTIVE: Recognizing the lack of formal evaluation on how these rankings are viewed beyond the pediatric urology community, this research endeavors to fill the gap through sentiment analysis of public news articles and academic publications. STUDY DESIGN: We captured news articles from Google News and academic papers from Ovid Medline and Embase, focusing specifically on content related to the USNWR pediatric urology rankings from 2009 to 2023. Sentiment analysis was conducted using the Valence Aware Dictionary and Sentiment Reasoner (VADER) package on both news and academic texts, aiming to capture the overall sentiment through a compound score derived from the presence of sentiment-laden words. Sensitivity analysis was performed using TextBlob Pattern Analyzer tool. RESULTS: The analysis revealed a significant divergence in sentiment between news articles and academic literature. News articles exhibited a predominantly positive sentiment, with an average compound score of 0.681, suggesting a general approval or celebration of the rankings in the public sphere. Conversely, academic literature showed a more moderate sentiment, with an average score of 0.534, indicating a nuanced perspective that includes both positive views and critical reflections on the rankings. Sensitivity analysis confirmed this observation (Figure). DISCUSSION: This difference may reflect the distinct nature of news media and academic discourse. While news outlets may prioritize celebratory narratives that align with public interest and institutional pride, academic discussions tend to offer a balanced view that critically assesses both the merits and limitations of the rankings. This discrepancy underscores the complexity of interpreting and acting upon the rankings within the pediatric urology community. CONCLUSION: While the USNWR pediatric urology rankings are generally received positively by the public, as reflected in news media, the academic community presents a more reserved sentiment. These findings suggest the need for ongoing dialogue and research to understand the implications of these rankings fully. It also calls for a strategic approach to address the concerns and perceptions of healthcare professionals, aiming to leverage the rankings in a way that truly benefits patient care and informed decision-making.

INTRODUCTION: Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) are structural disorders originating prenatally and present at birth. Affecting 4.2 to 1000 per 10,000 births globally, CAKUT includes conditions like posterior urethral valves, cloacal anomalies, and reflux nephropathy. These anomalies can lead to chronic kidney disease (CKD) or end-stage kidney disease (ESKD) in children, necessitating renal replacement therapy or transplantation. OBJECTIVES: This article aims to provide an updated perspective on pediatric kidney transplantation for children with CAKUT, emphasizing pre-transplant evaluation and management to optimize long-term outcomes. METHODS: A comprehensive urologic evaluation is essential for children with ESKD being considered for kidney transplantation. Key pre-transplant investigations include kidney/bladder ultrasound (US), voiding cystourethrogram (VCUG), uroflowmetry, and urodynamics (UDS)/video-urodynamics (VUDS). Non-operative interventions such as pharmacotherapy and clean intermittent catheterization (CIC) are also considered. Surgical interventions, like augmentation cystoplasty or continent catheterizable channels, are evaluated based on individual patient needs. RESULTS: Kidney/bladder US and VCUG provide essential anatomical information. UDS offers comprehensive functional data, identifying hostile bladders needing pre-transplant optimization. Non-surgical measures like anticholinergics and CIC improve bladder function, while surgical options enhance compliance and capacity. Concurrent interventions during transplantation are feasible but require careful consideration of risks and benefits. DISCUSSION: Children with CAKUT undergoing kidney transplantation exhibit comparable or better graft survival rates than those without CAKUT. However, those with lower urinary tract obstructions (LUTO) may have poorer long-term outcomes. UDS is crucial for evaluating bladder function pre-transplant, guiding the need for interventions. Long-term monitoring for urinary tract infections (UTIs) and bladder dysfunction is essential. CONCLUSION: Optimal outcomes in pediatric kidney transplantation for CAKUT patients require thorough pre-transplant evaluation and management, particularly for those with LUTO. Multidisciplinary approaches ensure careful monitoring and timely interventions, improving graft survival and quality of life for these patients.
RESUMO
INTRODUCTION: The morphology of the bladder and posterior urethra on initial voiding cystourethrogram (VCUG) in posterior urethral valve (PUV) has been proposed as a meaningful early metric for short- and long-term kidney outcomes. Here, we seek to externally validate the proposed association and assess the reliability of PUV morphology characteristics. MATERIALS AND METHODS: We reviewed our institutional database for patients managed for PUV between 2000 and 2022 and included those treated with primary ablation with at least 1 year of follow-up for kidney function. Each VCUG was evaluated by three independent raters for the height-width ratio of the bladder (HW-B), height-width ratio of the posterior urethra (HW-PU), and posterior-anterior urethral ratio (PA-UR), and trabeculation (none, fine, or coarse). We assessed the reliability in these with intra-class coefficient and Fleiss kappa for continuous and categorical data, respectively. We performed univariate analysis with nadir creatinine and five-year follow-up glomerular filtration rate (GFR). RESULTS: In total, 98 patients met inclusion criteria. The median age at diagnosis and ablation was 10 and 21 days, respectively. Patients with nadir creatinine <0.8 mg/dL had higher follow-up GFR (101 vs. 20 ml/min/1.73 m2, p = 0.04), and lower risk of CKD (odds ratio 14.7, p = 0.002). The median value for HW-B was 1.4, median HW-PU was 2.1, and median PA-U was 4.7, There was significant inter-class agreement between all three measures of 0.80, 0.51, and 0.70 (p < 0.001). The inter-rater agreement for bladder trabeculation was fair (Fleiss K = 0.40, p < 0.001). There was no statistically significant correlation between HW-B, HW-PU, PU-A with nadir creatinine (p = 0.07, 0.33, 0.91) or 5-year GFR (0.27, 0.45, 0.62), respectively. DISCUSSION: There is significant interest in determining prognostic factors and metrics in PUV. The morphological characteristics on VCUG are reliable and is available information for all boys diagnosed with PUV, resulting in an attractive metric. While we do not demonstrate correlation with kidney outcomes, VCUG features warrant further attention as prognostic factors in PUV. CONCLUSIONS: PUV morphology on initial VCUG is a reliable metric of lower urinary tract deformity but is not associated with 5-year kidney outcomes.

PURPOSE: This systematic review and meta-analysis aimed to compare the effectiveness and safety of submucosal injection of onabotulinum toxin A (OnabotA) with intradetrusor injection for overactive bladder syndrome (OAB). METHODS: This systematic review is registered with PROSPERO (CRD42021237964). A licensed librarian surveyed Medline, EMBASE, Scopus, and Google Scholar databases to conduct a comprehensive search. Studies comparing suburothelial and intradetrusor techniques of OnabotA injection for OAB were included, along with clinical and urodynamic variables and complications. The studies were assessed for quality on the basis of Cochrane Collaboration guidelines and evaluated using statistical analysis via a random-effect model and I2 statistic. Data extraction and analysis were conducted using Covidence systematic review platform and Review Manager software. RESULTS: Six studies with 299 patients were included in the systematic review, with four reporting that suburothelial injection of OnabotA was as effective as intradetrusor injection and two reporting intradetrusor injection to be more effective. The meta-analysis found no significant difference between the suburothelial and intradetrusor groups for mean daily catheter or voiding frequency (mean difference: 2.12 [95% confidence interval (CI): -1.61, 5.84]) and the mean number of urgency/urge incontinence episodes (mean difference: 0.08 [95% CI: -1.42, 1.57]). However, a significant heterogeneity was found among the studies. Only the mean volume at first detrusor contraction showed a significant difference, being higher for suburothelial injection (mean difference: 33.39 [95% CI: 0.16, 66.63]). No significant difference was noted for mean compliance, mean bladder capacity, and mean maximum detrusor pressure. Urinary tract infections (UTIs) (p = 0.24) and acute urinary retention (p = 0.92) showed no significant difference between the two groups. The risk of bias varied among the studies. CONCLUSIONS: Suburothelial injection of OnabotA is as effective as intradetrusor injection in improving OAB symptoms, and it has similar complication rates. A higher mean volume of the first detrusor contraction was found in a urodynamic study with suburothelial injection.

INTRODUCTION: Posterior urethral valves (PUV) is a chronic condition that can adversely impact child and family health related quality of life (HRQOL). Surprisingly, to date, the impact of this condition on the QOL of children with PUV has not been studied. Thus, our aim is to evaluate this important aspect of care using validated questionnaires in our institutional PUV clinic. METHODS: From December 2022 to January 2024, the PedsQL Inventory and associated family impact module was distributed in our PUV clinic. Higher scores reflect better HRQoL and less impact on family. Children >8 years old completed the tool themselves, otherwise parents completed the tools on behalf of the child. We compared PUV scores against reported psychometric data from healthy children and other chronic illnesses. RESULTS: A total of 112 families completed the questionnaires. The total HRQoL score was 80 ± 13. Overall, we noted that the domains reflecting psychosocial impact were significantly lower than those of physical well-being (76 ± 16 vs. 89 ± 15 for psychosocial and physical impact, respectively; p < 0.01). There was a significant difference in the psychosocial emotional impact for children managed with clean intermittent catheterization (CIC) compared to those who were not (69 ± 21 vs. 81 ± 16; p = 0.005) (Table 2). In addition, we noted that children with PUV scored similar to healthy controls, but higher than children with other chronic illnesses. With respect to the impact on family, overall, parent, and family impacts were 76 ± 19, 78 ± 21, and 81 ± 21, respectively. DISCUSSION: Chronic illness has been associated with a negative impact on HRQoL in both adults and children. We noted similar findings the present study, particularly for young children and those who are maintained on CIC. To our knowledge, this is the first study to evaluate the impact of PUV on a child's HRQoL as well as the impact on the family, and to document a negative psychosocial impact of CIC in this population. However, there are some important limitations to be addressed including relying on families to complete questionnaires accurately during busy clinic visits and the lack of controls from the same environment. CONCLUSION: When compared to healthy controls, PUV patients score similarly in HRQoL assessment. In addition, children <3years of age report a negative impact on physical well being, and CIC negatively impacts the emotional well-being. These data can be used to advocate for better mental health supports and social work for these children.

BACKGROUND: Little is known about alpha blocker use in young children, particularly in those with lower urinary tract obstruction (LUTO). Therefore, we aimed to assess the safety and tolerability of selective alpha-blockers in children under 3 years of age with LUTO. METHODS: A prospectively-collected database captured 93 patients born between 12/2005 and 01/2023. Assessed data included baseline characteristics, ultrasound features, blood pressure (BP), side effects and creatinine values. Primary outcome was side effects or discontinuation of alpha-blockers. Secondary outcomes were BP parameters, growth, and kidney function. Data are shown as median with interquartile range (IQR), Odds Ratio (OR) with 95% CI and mean value with standard deviation (SD). RESULTS: A total of 33 patients less than 3 years of age were started on alpha-blockers at 16.8 ± 11.8 months and followed for 48.9 ± 40.5 months. At last follow-up, no significant effect on systolic/diastolic BP percentiles (p > 0.9 and p > 0.9), creatinine levels (p > 0.9). Weight percentiles increased to the last follow-up (37.8 ± 33.2 vs. 53.6 ± 32.9, p = 0.0133) while height percentiles increased from 28 to 100 days to last follow-up (12.9 ± 18.3 vs. 39.6 ± 35.2, p=0.001). Four patients discontinued alpha-blockers; however, no side-effects were reported during the study period. CONCLUSIONS: No severe clinical or systemic side effects were observed, demonstrating safety and tolerability in young children with LUTO. Although alpha-blockers did not significantly improve kidney function in short term follow-up, and failure to thrive was not observed in these children. Additional studies with more patients are required to assess the optimal dosing and timing leading to maximal benefits for these infants.

OBJECTIVES: To compare postnatal outcomes of AUV and PUV patients to evaluate for potential differences between these conditions, given that anterior urethral valves (AUV) with or without concomitant posterior urethral valves (PUV) is a rare congenital anomaly leading to lower urinary tract obstruction (LUTO). METHODS: We reviewed our LUTO database and included patients with AUV or concomitant AUV+PUV, managed at our institution between 2003 and 2023 matching them to comparable PUV cases. Assessed variables included prenatal diagnosis, gestational age (GA) at birth, initial management, kidney function, presence and degree of hydronephrosis (HN), and need for renal replacement therapy (RRT). RESULTS: The AUV ± PUV group (AUV: n=11, concomitant PUV: n=2) and PUV group (n=26) had similar presenting ages and follow-up times (p>0.05). Only 15.4% of AUV cases presented prenatally compared to 72.0% of PUV cases (p=0.0016), leading to delayed postnatal management in AUV patients (p=0.0260). Findings at presentation included UTI, weak stream or a palpable penile mass. PUV patients demonstrated significantly higher creatinine levels at the initial visit and at last follow-up (p=0.0120 and p=0.0302) than the AUV ± PUV group, with only one patient requiring RRT (p>0.05). At the last follow-up, no patient in the AUV ± PUV group required clean intermittent catheterization compared to 37.5% in the PUV group (p=0.0331) which also demonstrated more patients with persistent HN (p=0.0039). CONCLUSION: AUV with or without concomitant PUV is a rare finding that should be considered in patients presenting with weak stream, UTI, and penile swelling. Our data suggests potential differences in presentation and less severe postnatal outcomes in AUV compared to PUV patients.
RESUMO
INTRODUCTION: Refractory bladder and bowel dysfunction (BBD) significantly affects the health and quality of life of children and their caregivers, emphasizing the need for effective and minimally invasive treatments. This study aims to present the inaugural Canadian experience using sacral neuromodulation (SNM ) as a therapeutic option for children with refractory BBD. METHODS: Patients <18 years old with refractory BBD were prospectively followed from 2018 to the present. Preoperative evaluation included spinal MRI and video urodynamics. Two-stage SNM implantation was executed with a minimum two-week stage 1 trial. Functional outcomes and complication rates were measured following validated questionnaires. RESULTS: Six patients completed staged implantation at a median age of 10.8 years (range 8.2-18). The median baseline Dysfunctional Voiding Scoring System (DVSS) score was 12.5 (10-22). At six months of followup, only one patient required adjunct bladder medication. Median DVSS at one-year followup was 5.5 (0-7). Symptomatic resolution was noted in three patients at six months, sustained over one year. Early surgical complications were reported in one (infection) and late complications in three (lead fracture, battery depletion, non-traumatic malfunction), requiring reimplantation at a median of 37.5 (1-49) months. Post-SNM reimplantation, oral medication and rectal therapy decreased, and DVSS scores improved by 30% (0-63.6) at six months. CONCLUSIONS: SNM is feasible and offers promising results for refractory pediatric BBD in Canada. The significant improvement of symptoms highlights the treatment's potential, which must be balanced against the high need for revision detected at three years, possibly related to patients' growth and high activity level.
RESUMO
INTRODUCTION: Advances in health care have improved outcomes for pediatric patients with congenital neurourological conditions, highlighting the need for an effective transition from pediatric to adult care. This study investigates Canada's transitional urologic care within its single-payer health care system, focusing on the active members of Pediatric Urologists of Canada and their practices, perceptions, and attitudes toward transitional urologic care. METHODS: A survey was distributed to 35 Pediatric Urologists of Canada members from July 2023 to January 2024, which collected data on transitional care practices and available transitional urology clinics. It also focused on a service overview, covering aspects such as the responder's geographic and institutional affiliations, clinical practice characteristics involving transitional care, perceived challenges, and strategies for care enhancement. RESULTS: Nationwide engagement emphasized a commitment to improving transitional care, with a significant proportion of respondents (64%) having over 10 years of practice, reflecting substantial experience in addressing transitional care challenges. The survey identified 4 dedicated transitional care clinics, 3 of which are active, pointing to concerted efforts toward specialized service provision. The major challenges identified include the lack of adult transitional care initiatives and governmental support. Recommendations for improvement should focus on standardizing transition protocols and boosting patient education. The survey also underscored the necessity of protocolized care for spina bifida-neurogenic bladder and complex urogenital conditions. CONCLUSIONS: This study highlights the active efforts and existing challenges within Canada's transitional urologic care system, particularly emphasizing operational transitional care clinics as a crucial step forward in catering to transitioning patients' needs.

BACKGROUND: While device-based circumcision is considered non-inferior to traditional dissection, there is no consensus on the efficacy and safety of ring devices in comparison with clamp devices. We aimed to compare the safety outcomes of ring-based versus clamp-based circumcision techniques in neonates. METHODS: MEDLINE, EMBASE, Scopus, and CINAHL were searched following the Cochrane collaboration (PRISMA guidelines), without language restrictions, to identify relevant randomized controlled trials. Adverse events, bleeding events, infection events, and procedure time were extracted and analyzed from the selected studies. RESULTS: From 1661 citations, seven trials were included, encompassing 3390 patients. These studies compared ring-based to clamp-based circumcision devices in neonates. No significant difference was found in overall adverse events between the two groups. However, ring devices showed significantly fewer bleeding events compared to clamp devices. Infection events and procedure time were similar for both groups. CONCLUSIONS: Both ring and clamp devices have similar safety profiles, with ring devices potentially offering a reduced risk of bleeding. A comprehensive understanding of ring-specific complications and cosmetic outcomes is necessary for a more complete evaluation of these circumcision techniques. Our analysis is limited from a lack of detailed examination of ring-specific complications and their impact on cosmetic results. The included studies varied in quality, and some exhibited a risk of bias. LEVEL OF EVIDENCE: Level IV Treatment Study.
RESUMO
Bladder embryonal rhabdomyosarcomas (ERMS) are malignant soft tissue tumors that rarely present in the perinatal period. Herein, we report 2 cases that were diagnosed in the newborn period (one with concomitant posterior urethral valves [PUV]), managed with chemotherapy and surgical resection to minimize the need for radiation.
RESUMO
INTRODUCTION: Artificial intelligence (AI) and machine learning (ML) in pediatric urology is gaining increased popularity and credibility. However, the literature lacks standardization in reporting and there are areas for methodological improvement, which incurs difficulty in comparison between studies and may ultimately hurt clinical implementation of these models. The "STandardized REporting of Applications of Machine learning in UROlogy" (STREAM-URO) framework provides methodological instructions to improve transparent reporting in urology and APPRAISE-AI in a critical appraisal tool which provides quantitative measures for the quality of AI studies. The adoption of these will allow urologists and developers to ensure consistency in reporting, improve comparison, develop better models, and hopefully inspire clinical translation. METHODS: In this article, we have applied STREAM-URO framework and APPRAISE-AI tool to the pediatric hydronephrosis literature. By doing this, we aim to describe best practices on ML reporting in urology with STREAM-URO and provide readers with a critical appraisal tool for ML quality with APPRAISE-AI. By applying these to the pediatric hydronephrosis literature, we provide some tutorial for other readers to employ these in developing and appraising ML models. We also present itemized recommendations for adequate reporting, and critically appraise the quality of ML in pediatric hydronephrosis insofar. We provide examples of strong reporting and highlight areas for improvement. RESULTS: There were 8 ML models applied to pediatric hydronephrosis. The 26-item STREAM-URO framework is provided in Appendix A and 24-item APPRAISE-AI tool is provided in Appendix B. Across the 8 studies, the median compliance with STREAM-URO was 67 % and overall study quality was moderate. The highest scoring APPRAISE-AI domains in pediatric hydronephrosis were clinical relevance and reporting quality, while the worst were methodological conduct, robustness of results, and reproducibility. CONCLUSIONS: If properly conducted and reported, ML has the potential to impact the care we provide to patients in pediatric urology. While AI is exciting, the paucity of strong evidence limits our ability to translate models to practice. The first step toward this goal is adequate reporting and ensuring high quality models, and STREAM-URO and APPRAISE-AI can facilitate better reporting and critical appraisal, respectively.
