Introduction: Ureteropelvic Junction Obstruction (UPJO), is a major cause of pathological hydronephrosis in children. Minimally invasive surgery (MIS), including laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP), has gained popularity due to its known advantages. LP faces technical difficulties and a steep learning curve. RALP has overcome these limitations, making it safer and more effective for children. The study aims to assess the safety and effectiveness of LP and RALP in infants weighing ≤15 kg., Materials and Methods: This is a retrospective analysis (2010-2022). The study included pediatric patients who had a confirmed diagnosis of UPJO and weighed ≤15 kg. The patients were divided into two groups: LP and RALP. The study evaluated preoperative, intraoperative, perioperative, and follow-up data, including complications. Success was defined as no worsening of hydronephrosis on postoperative ultrasound in the first year of follow-up., Results: The total patients were 94: 42 in the LP group, and 52 in the RALP group. The median age at the intervention was 17.5 months (LAP group) versus 29 months (RALP group) (p = 0.01). The median weight at the time of intervention was 9.5 Kg (LP group), and 11.6 Kg (RALP group) (p = 0.44). The median operative time was significantly longer in the LP group: 245 min versus 125.5 min in the RALP group (p = 0.001). The median length of hospitalization was comparable: 4.3 days (LP group) and 3.5 days (RALP group) (p = 0.42). No intraoperative complications were reported in either group. There were no statistically significant differences regarding postoperative complications. During follow-up, all patients remained asymptomatic, with no episodes of urinary tract infection or abdominal pain, and none of them had a recurrence of UPJ obstruction. Consequently, the two techniques are equally effective and safe in the short term., Discussion: Both procedures offer excellent outcomes with comparable postoperative complications. LOS was similar for both groups, with no intraoperative complications or conversions, and a non-significant increase in postoperative complications. A notable finding was the significant difference in operation times between the procedures, emphasizing the importance of reduced surgical time in pediatric patients for minimizing anesthetic and intubation durations., Conclusion: For the absence of intra- and postoperative complications and recurrences, RALP is as effective as LP in pyeloplasty in children weighing 15 kg or less. This finding reinforces the idea that RALP can be safely executed, benefiting from its advanced technology and the learning curve, for patients of any age regarding pyeloplasty for UPJO., Competing Interests: Conflict of interest None., (Copyright © 2024 Journal of Pediatric Urology Company.

Background: A congenital disease is for life. Posterior hypospadias, the severe form of hypospadias with a penoscrotal, scrotal, or perineal meatus, is a challenging condition with a major impact on lifelong quality of life., Aim: Our network meeting is aimed to identify what is currently missing in the lifelong treatment of posterior hypospadias, to improve care, quality of life, and awareness for these patients., Methods: The network meeting "Lifelong Posterior Hypospadias" in Utrecht, The Netherlands was granted by the European Joint Programme on Rare Diseases-Networking Support Scheme. There was a combination of interactive sessions (hackathons) and lectures. This paper can be regarded as the last phase of the hackathon., Results: Surgery for hypospadias remains challenging and complications may occur until adulthood. Posterior hypospadias affects sexual function, fertility, and hormonal status. Transitional care from childhood into adulthood is currently insufficiently established. Patients should be more involved in defining desired treatment approach and outcome measures. For optimal outcome evaluation standardization of data collection and registration at European level is necessary. Tissue engineering may provide a solution to the shortage of healthy tissue in posterior hypospadias. For optimal results, cooperation between basic researchers from different centers, as well as involving clinicians and patients is necessary., Conclusions: To improve outcomes for patients with posterior hypospadias, patient voices should be included and lifelong care by dedicated healthcare professionals guaranteed. Other requirements are joining forces at European level in uniform registration of outcome data and cooperation in basic research., (© 2023 The Authors.

Introduction: Traditionally, open ureteral reimplantation (OUR) has been the standard treatment for primary vesicoureteral reflux (VUR) requiring reimplantation. Robotic-assisted laparoscopic ureteral reimplantation (RALUR) is gaining popularity and high success rates have been reported., Objective: In this multi-institutional study, we aimed to compare the perioperative and postoperative outcomes of OUR and RALUR for high-grade (IV + V) VUR in children., Study Design: A retrospective evaluation was performed collecting data from 135 children (0-18 years) who underwent high grade VUR surgical correction at nine European institutions between 01/01/2009 and 01/12/2020, involving either open or robotic approaches. Institutional review board approval was obtained. Patients with lower grades of VUR (≤III), previous history of open or endoscopic ureteral surgery, neurogenic bladder, or refluxing megaureter in need of ureteral tapering were excluded. Pre-, peri- and post-operative data were statistically compared., Results: Overall, 135 children who underwent either OUR (n = 68), or RALUR (n = 67) were included, and their clinic and demographic features were collected. The mean age of the open group was 11 months (interquartile range [IQR] 9.9-16.6 months), in the RALUR group it was 59 months (IQR 29-78mo) (p < 0.01); the open cohort had a weight of 11 kg (IQR 9.9-16.6 kg) while the RALUR group had 19 kg (IQR 13-25 kg) (p < 0.01). No significant differences were found for intraoperative (1.5 % vs 7.5 %, p = 0.09) or for postoperative complication rates (7.4 % vs 9 %, p = 0.15). Favorable outcomes were reported in the RALUR group: shorter time to stooling (1 vs 2 days), fewer indwelling urethral catheter days (1 vs 5 days), perioperative drain insertion time (1 vs 5 days) and a shorter length of hospital stay (2 vs 5 days) (p < 0.01). The success rate was 94.0 % and 98.5 % in the open and RALUR groups, respectively. The long-term clinical success rates from both groups was comparable:42 vs 23 months for open and RALUR, respectively., Discussion: This study reported a large multicentric experience focusing on high grade VUR. Furthermore, this study compares favorably to OUR in a safety analysis. There was also a trend towards higher success rates with RALUR utilizing an extravesical approach which has not been previously reported., Conclusion: RALUR is an efficacious and safe platform to use during ureteral reimplantation for high grade VUR. The overall peri-operative and post-operative complication rates are at least equivalent to OUR, but it is associated with a faster functional recovery and time to discharge. Medium to long term success rates are also equivalent to OUR., Competing Interests: Conflict of interest Nil., (Copyright © 2023 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Objective: To identify any self-reported differences or attitudes towards certification, publication, or practice patterns between adult urology and paediatric general surgery-trained paediatric urology providers. There are no known published differences in clinical/operative/research outcomes in either group., Methods: An 18-item cross-sectional survey was compiled through the EAU Young Academic Urologists (YAU) office and disseminated to a trans-Atlantic convenience sample of current practising paediatric urologists. This was created using a mini-Delphi method to provide current semi-quantitative data relating to current opinions and attitudes of this cohort., Results: A total of 228 respondents completed the survey, with female respondents representing 37% and 34% for urology and paediatric general surgery, respectively. Nearly 90% overall respondents felt that a full 2-year paediatric fellowship program was very important and 94% endorsed a collaborative dedicated paediatric urology on call service, with 92% supporting the joint development of transitional care. Urology managed higher numbers of bedwetting (p = 0.04), bladder bowel dysfunction (p = 0.02), endourological procedures (p = 0.04), and robotics (p = 0.04). Paediatric general surgery managed higher numbers of laparoscopic reconstruction (p = 0.03), and posterior urethral valve ablation (p = 0.002)., Conclusion: This study represents the first time that a cross-sectional cohort of paediatric urologists from different training backgrounds were compared to assess their productivity, practice patterns and attitudes. Paediatric urology is in a unique position to have two contributing specialities, with the ability to provide optimal transitional and lifelong care. We believe that there should be a strong emphasis on collaboration and to remove any historically-created barriers under policies of equity, diversity and inclusivity., (© 2024. The Author(s).)

Objective: To evaluate strategies that are followed after pediatric renal trauma during the recovery stage, with an emphasis on mobility and involvement in subsequent sporting activities. Renal trauma is the most common urogenital trauma in children. The American Association for the Surgery of Trauma (AAST) scale is most commonly used to stratify the severity of injury. There is no consensus in the existing literature with respect to the recovery stage following renal trauma., Methods: A survey was constructed by the European Association of Urology (EAU) - Young Academic Urologists (YAU) Pediatric Urology Working Group and then made digitally available on SurveyMonkey. The survey consists of 15 questions exploring relevant factors and timing to start again with mobility and activity., Results: In total 153 people responded, of whom 107 completed the entire survey. The presence of pain and severity of trauma were acknowledged as most important factors to commence mobilization, whereas presence of hematuria was identified as an additional factor for sporting activity. Regardless of severity of trauma a minimum of 90% of respondents recommend return to noncontact sports within 12weeks. For contact sports, a minimum of 33% of respondents advised >12weeks minimum before starting again. A small number of respondents would never allow sporting activities again., Conclusion: The time to allow sporting activity shows high variation among the respondents, some even restricting sporting activities completely. This survey highlights the need for a standardized protocol based on multicenter follow-up data., Competing Interests: Declaration of Competing Interest The authors have no relevant conflicts of interest to report for this study., (Copyright © 2023 The Authors.

Purpose: Bladder and bowel dysfunction is a common but underdiagnosed pediatric entity which may represent up to 47% of pediatric urology consults. The objectives of this observational study were to determine functional 1-year outcomes following standard treatment of bladder and bowel dysfunction in both control and neuropsychiatric developmental disorder groups using validated questionnaires, and to perform an initial cost analysis., Materials and Methods: This was a prospective observational study conducted across a number of academic European centers (July 2020-November 2022) for new bladder and bowel dysfunction patients. Parents completed a sociodemographic survey, information pertaining to prior neuropsychiatric developmental disorder diagnoses, as well as a number of validated functional scores., Results: A total of 240 patients were recruited. In the control bladder and bowel dysfunction group, the baseline Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores were 20% and 17.% lower, respectively, after 1 year compared to the neuropsychiatric developmental disorder group. The change in improvement was diminished for the neuropsychiatric developmental disorder cohort in both Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores. The odds ratio of full symptom resolution was 5.7 in the control cohort compared to the neuropsychiatric developmental disorder cohort. A cost analysis on prescribed medications at referral led to a total cost of €32,603.76 (US $35,381.00) in the control group and €37,625.36 (US $40,830.00) in the neuropsychiatric developmental disorder group., Conclusions: This study demonstrates that pediatric patients with a neuropsychiatric developmental disorder exhibit more severe bladder and bowel dysfunction at baseline and throughout treatment with a lower overall quality of life, as well as 15.4% higher medication costs at referral. It is also important that parents' and caregivers' expectations are managed regarding higher levels of treatment resistance for functional bladder and bowel issues.

Introduction: Complex urological anomalies often require continued care as patients reach adulthood. Adequate transition for adolescents with ongoing urological care needs is critical to allow for seamless care in adult hospitals. Studies have shown that this can lead to improved patient and parental satisfaction, and lower utilisation of unplanned inpatient beds and emergency department visits. There is currently no ESPU-EAU consensus on the adequate mechanism and very few individual papers examining the role of urological transition for these patients in a European setting. This study aimed to identify current practice patterns in paediatric urologists providing adolescent/transitional care, to assess their opinions towards formal transition and to look for variations in care. This has implications for long-term patient health and specialist care., Methods: An 18-item cross-sectional survey was compiled and pre-approved through the EAU-EWPU and ESPU board offices prior to dissemination to all registered ordinary members affiliated with the ESPU. This was created using a mini-Delphi method through the EWPU research meetings to provide current semi-quantitative data relating to current opinions and attitudes of this cohort., Results: A total of 172 respondents (55% paediatric general surgery; 45% urology) across 28 countries completed the survey. The majority of respondents were in practice >10 years and spent >80% time in paediatric urology. There was no formal transition process according to 50% respondents and over half of those that did have less than 1/month, with <10% using validated questionnaires. More than two-thirds respondents continued to provide care after transition, as >70% units had no designated corresponding adult service. Furthermore, 93% paediatric believe a formal transition service to be very important, using a multidisciplinary framework. A pareto chart demonstrated 10 specific conditions to be of most interest in transition to adulthood., Conclusion: This is the first study to assess the requirements of paediatric urologists for adequate transitional care, however due to the nature of the survey's distribution, this was a non-scientific poll based on a convenience sample of respondents. It is critical that dual-trained or adult-trained urologists with a specific interest in paediatric urology work with current paediatric urologists in a multidisciplinary fashion to facilitate early transition based on the adolescent's developmental and biopsychosocial requirements. National urological and paediatric surgical societies need to make transitional urology a priority. The ESPU and EAU should collaboratively consider developing transitional urology guidelines to allow a framework by which this can occur., Competing Interests: Conflicts of interest The authors declare that there are no actual or perceived conflicts of interest., (Copyright © 2023 Journal of Pediatric Urology Company.

Background: The term glass ceiling coined by Loden in 1978 is commonly used to describe difficulties faced by minorities and women when trying to move into senior roles., Objective: To analyse trends and patterns for female representation at the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) annual general meetings over the past decade., Design Setting and Participants: We used objective data on female representation in the roles of chairs, moderators, and lecture speakers at the EAU and ESPU meetings from 2012 to 2022., Outcome Measurements and Statistical Analysis: We evaluated gender based representation in paediatric urology sessions at the EAU and ESPU meetings, collecting data on the overall number of sessions, lectures, symposiums, abstract/poster sessions, and courses, and analysed the male/female ratio. Data were derived from printed and digital programmes for the relevant meetings., Results and Limitations: During the period from 2012 to 2022, the percentage female representation varied from 0% (2012) to a maximum of 35% (2022) at EUA paediatric urology sessions, and from 13.5% (2014) to a maximum of 32% (2022) at ESPU meetings. Both associations show clear progression towards equality., Conclusions: Female representation at EAU and ESPU meetings has risen over the years, reaching 35% and 32%, respectively, in 2022, which is in line with the number of female members. We hope that this motivates a move towards the equality objectives for 2030. A clear and fundamental societal change is needed, with fair and more consistent institutional policies and framework commitments in the areas of science, medicine, and global health. Gender equality and diversity taskforces are essential to achieve these goals., Patient Summary: We analysed the male/female ratio for participants in annual meetings held by the European Association of Urology and the European Society for Paediatric Urology. From a low level in 2012, the ratio increased to over 30% in 2022, in line with the female membership of the societies. Focus on fair and consistent policies is needed to ensure that women are well represented in medicine., (© 2023 The Authors. Published by Elsevier B.V. on behalf of European Association of Urology.)

Background: Paediatric nephrolithiasis has increased globally, requiring standardized recommendations. This study aims to assess the paediatric urolithiasis care between EAU members along with the statements of three experts in this field. Methods: The results of an electronic survey among EAU members comparing the guideline recommendations to their current practice managing paediatric nephrolithiasis in 74 centres are contrasted with insights from an expert-panel. The survey consisted of 20 questions in four main sections: demographics, instrument availability, surgical preferences and follow-up preferences. Experts were asked to give insights on the same topics. Results: A total of 74 responses were received. Computerised Tomography was predominantly used as the main imaging modality over ultrasound. Lack of gonadal protection during operations was identified as an issue. Adult instruments were used frequently instead of paediatric instruments. Stone and metabolic analysis were performed by 83% and 63% of the respondents respectively. Conclusions: Percutaneous Nephrolithotomy is the recommended standard treatment for stones > 20 mm, 12% of respondents were still performing shockwave lithotripsy despite PNL, mini and micro-PNL being available. Children have a high risk for recurrence yet stone and metabolic analysis was not performed in all patients. Expert recommendations may guide clinicians towards best practice.

Introduction: Non-muscle invasive bladder cancer (NMIBC) is a highly recurrent disease with potential progression to muscle invasive disease despite the standard bladder instillations with mitomycin C (MMC) or Bacille Calmette-Guérin immunotherapy. Therefore, alternatives such as radiofrequency-induced chemohyperthermia (RF-CHT) with MMC are being investigated. The mechanism explaining the efficacy of RF-CHT is only partly understood. We examined whether RF-CHT results in higher MMC tissue concentrations as compared to cold MMC instillation., Patients and Methods: Prior to a planned transurethral resection of bladder tumour (TURBT), patients with stage Ta NMIBC were allocated to either (1) cold MMC instillation or (2) RF-CHT. After MMC instillation, three biopsies were taken of both normal and tumour tissue. Biopsies were snap-frozen and MMC tissue concentrations were analysed using ultra-performance liquid chromatography., Results: Eleven patients were included of which six received RF-CHT. Ten patients had TaG2-LG/HG papillary tumours at pathology. One patient in the RF-CHT group appeared to be free of malignancy and was excluded from the analysis as no tumour biopsies were available. The median MMC concentration in tumour tissue was higher in the RF-CHT group (median 665.00 ng/g vs. 63.75 ng/g, U = 51.0, p = 0.018). Moreover, in both techniques the MMC concentration was lower in normal tissue compared to tumour tissue. Tissue MMC concentration measurements varied substantially within, and between, different patients from the same group., Conclusion: Intravesical RF-CHT results in higher tumour MMC concentrations vs. cold MMC instillation which contributes to its superior efficacy.
