ABSTRACT
Introducción El trasplante renal es el tratamiento de elección para pacientes con enfermedad renal crónica (ERC) estadio 5. Alrededor de 60% de los pacientes con ERC presentan sobrepeso u obesidad en el momento del trasplante de riñón, y la obesidad postrasplante se da en 50% de los pacientes, con un aumento de peso de 10% en el primer año y un alto riesgo de mortalidad cardiovascular. La obesidad se asocia a un mayor riesgo de retraso de la función del injerto (RFI), rechazo agudo, complicaciones quirúrgicas, pérdida del injerto y mortalidad. El objetivo de este estudio es evaluar la evolución clínica de los pacientes obesos y con sobrepeso receptores de un trasplante renal, en términos de las complicaciones a corto y largo plazo asociadas a un mayor índice de masa corporal (IMC). Material y métodos Se realizó un estudio descriptivo, observacional y transversal con 104 pacientes sometidos a trasplante de riñón o páncreas-riñón entre marzo de 2017 y diciembre de 2020, con seguimiento hasta abril de 2021. Para el análisis comparativo, los pacientes se agruparon según el IMC. Resultados La edad media fue de 56,65 años, 60,6% varones y 39,4% mujeres. Los pacientes con sobrepeso experimentaron cirugías más prolongadas, más dehiscencia de la herida quirúrgica, RFI, hernias, proteinuria y un requerimiento mayor de biopsias renales. Por otro lado, los pacientes obesos presentaron más RFI, mayor número de biopsias renales requeridas, proteinuria, desarrollo de diabetes mellitus y fibrilación auricular, y necesitaron estancias hospitalarias más prolongadas. Conclusiones A pesar de la alta prevalencia de comorbilidad en la población con sobrepeso y/u obesidad, no se observó un empeoramiento en la supervivencia del paciente y/o del injerto. Sin embargo, es necesario un seguimiento más prolongado. (AU)
Introduction Kidney transplantation is the treatment of choice for patients with stage 5 chronic kidney disease (CKD). About 60% of CKD patients are overweight or obese at the time of kidney transplantation, and post-transplant obesity occurs in 50% of patients, with a weight gain of 10% in the first year and high risk of cardiovascular mortality. Obesity is associated with an increased risk of delayed graft function (DGF), acute rejection, surgical complications, graft loss and mortality. The aim of this study is to assess the clinical evolution of obese and overweight patients that have received a kidney transplant, based on short- and long-term complications associated with a higher BMI. Material and methods A descriptive, observational, cross-sectional study was conducted with 104 kidney or pancreas-kidney transplant patients between March 2017 and December 2020, with a follow-up until April 2021. For comparative analysis, patients were grouped according to BMI. Results Mean age was of 56.65 years, 60.6% male and 39.4% female. Overweight patients experienced prolonged surgeries, more surgical wound dehiscence, delayed graft function, hernias, proteinuria and more indications for renal biopsies. Additionally, obese patients displayed more DGF, indications for renal biopsies, proteinuria, development of diabetes mellitus, atrial fibrillation and needed prolonged hospital stays. Conclusions Despite a high prevalence of comorbidity in the overweight and/or obese population, we found no reduction in patient and/or graft survival. However, longer follow-up is needed. (AU)

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.

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.

Introducción y objetivo El trasplante renal en la población pediátrica difiere del trasplante en adultos en muchos aspectos. Esta revisión se centrará en los aspectos exclusivos del receptor pediátrico. Material y métodos Se realizó una revisión narrativa de la escasa literatura existente sobre la evaluación preoperatoria del trasplante renal en receptor pediátrico con un enfoque educativo. La búsqueda bibliográfica permitió identificar publicaciones en inglés entre enero de 2000 y octubre de 2022. Los estudios publicados se identificaron mediante búsquedas en las siguientes bases de datos electrónicas: PubMed (Medline), WHO/UNAIDS, Google-Scholar, Semantic-Scholar y Research Gate. En aras de la eficacia y la fiabilidad, se utilizaron ensayos controlados aleatorizados, metaanálisis, revisiones sistemáticas de alta calidad y estudios grandes recientes bien diseñados, si estaban disponibles. Se realizaron búsquedas en internet para obtener información pertinente adicional (definiciones, políticas o directrices). Resultados El manejo de las anomalías urogenitales congénitas y la disfunción del tracto urinario inferior, junto con la evaluación urológica pediátrica preoperatoria óptima para el trasplante renal en niños, se ha abordado según la bibliografía disponible. Adicionalmente, se han mencionado consideraciones particulares relativas al trasplante preventivo y al trasplante de un riñón de tamaño adulto en un lactante o un niño pequeño. Conclusiones Los resultados del trasplante renal en niños han mejorado progresivamente en los últimos 15años. El trasplante de donante vivo emparentado ofrece los mejores resultados, y el trasplante preventivo puede ayudar a evitar la diálisis. Las consideraciones quirúrgicas y médicas, tanto en el tratamiento pretrasplante como en el postrasplante del receptor renal pediátrico, son extremadamente importantes para obtener resultados mejores a corto y a largo plazo (AU)
Introduction and objective Renal transplantation in the pediatric population differs from adults in many aspects. This review will focus on the unique issues of the pediatric recipient. Material and methods A narrative review on the scarce literature regarding preoperative evaluation before kidney transplantation of the paediatric recipient with an educational focus was conducted. The literature search allowed for identification of publications in English from January 2000 to October 2022. Published studies were identified by searching the following electronic databases: PubMed (Medline), WHO/UNAIDS, Google-Scholar, Semantic-Scholar and Research Gate. For efficiency and reliability, recent randomized controlled trials, meta-analyses, high quality systematic reviews and large well-designed studies were used if available. Internet searches were conducted for other relevant information (definitions, policies or guidelines). Results Management of congenital urogenital anomalies and lower urinary tract dysfunction along with optimal pediatric urological preoperative assessment for renal transplantation in children is addressed in the light of the available literature. Furthermore, particular considerations including pre-emptive transplantation, transplantation of an adult-size kidney into an infant or small child is discussed. Conclusions Outcomes of renal transplantation in children have shown progressive improvement over the past 15years. Transplantation with living related donor gives the best results and pre-emptive transplantation provides with benefits of avoiding dialysis. Surgical and medical considerations in both the pre-transplant and post-transplant management of the pediatric kidney recipient are extremely crucial in order to achieve better short and long-term results (AU)

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.

PURPOSE: Enhanced recovery after surgery (ERAS) is a perioperative management strategy to hasten postoperative recovery. We examined the effects of a pilot implementation of ERAS for pediatric patients on anesthetic outcomes. METHODS: We performed a prospective case-control study utilizing an ERAS protocol in patients aged < 18 years undergoing urologic reconstruction that included a bowel anastomosis. Protocol elements included: multimodal analgesia, opioid minimization, and routine nausea/vomiting prophylaxis. ERAS patients were propensity-matched with historical controls. Outcomes of interest included maximum PACU pain score, time to first opioid, opioid-free days, and need for opioids on day of discharge. RESULTS: A total of 13 ERAS patients and 26 historical controls were included, with median ages 9.9 years (IQR 9.1-11) and 10.4 years (IQR 8.0-12.4), respectively. ERAS increased the percentage of patients who did not receive any intraoperative or postoperative opioids (0% vs 15%, p = 0.046 for both) and reduced maximum PACU pain score (3 vs 0, p < 0.001). The use of postoperative supplemental oxygen was decreased in the ERAS group (85% vs 38%, p = 0.013). CONCLUSIONS: The implementation of an ERAS protocol appears to decrease postoperative pain, opioid usage, and positively impact other anesthetic outcomes in children undergoing urologic reconstructive surgery utilizing a bowel anastomosis.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocol is a set of peri-operative strategies to increase speed of recovery. ERAS is well established in adults but has not been well studied in children. OBJECTIVE: The purpose of the current study was to establish the safety and efficacy of an ERAS protocol in pediatric urology patients undergoing reconstructive operations. It was hypothesized that ERAS would reduce length of stay and decrease complications when compared with historical controls. STUDY DESIGN: Institutional Review Board approval was obtained to prospectively enroll patients aged <18 years if they had undergone urologic reconstruction that included a bowel anastomosis. ERAS included: no bowel preparation, administration of pre-operative oral carbohydrate liquid, avoidance of opioids, regional anesthesia, laparoscopy when feasible, no postoperative nasogastric tube, early feeding, and early removal of intravenous fluids (IVF). Recent (2009-2014) historical controls were propensity matched in a 2:1 ratio on age, sex, ventriculoperitoneal shunt status and whether the patient was undergoing bladder augmentation. Outcomes were protocol adherence, length of stay (LOS), emergency department (ED) visits, re-admission within 30 days, re-operations and adverse events occurring within 90 days of surgery. RESULTS: A total of 26 historical and 13 ERAS patients were included. Median ages were 10.4 (IQR 8.0-12.4) and 9.9 years (IQR 9.1-11), respectively (P = 0.94) (see Summary Table). There were no significant between-group differences in prior abdominal surgery (38% vs 62%), rate of augmentation (88% vs 92%) or primary diagnosis of spina bifida (both 62%). ERAS significantly improved use of pre-operative liquid load (P < 0.001), avoidance of opioids (P = 0.046), early discontinuation of IVF (P < 0.001), and early feeding (P < 0.001). Protocol adherence improved from 8/16 (IQR 4-9) historically to 12/16 (IQR 11-12) after implementation of ERAS. LOS decreased from 8 days to 5.7 days (P = 0.520). Complications of any grade per patient decreased from 2.1 to 1.3 (OR 0.71, 95% CI 0.51-0.97). There were fewer complications per patient across all grades with ERAS. No differences were seen in emergency department (ED) visits, re-admissions and re-operations. DISCUSSION: Implementation improved consistency of care delivered. Tenets of ERAS that appeared to drive improvements included maintenance of euvolemia through avoidance of excess fluids, multimodal analgesia, and early feeding. CONCLUSION: ERAS decreased length of stay and 90-day complications after pediatric reconstructive surgery without increased re-admissions, re-operations or ED visits. A multicenter study will be required to confirm the potential benefits of adopting ERAS.

Selenium is shown to have beneficial effects on ischaemia-reperfusion (IR) injury. Our aim was to assess the effects of selenium on IR-induced testicular damage in terms of biochemical and histopathological evaluation. A total of 32 rats were randomised into four groups: control, IR, IR + selenium (IR + S) and S. Detorsion was applied after 3 h of torsion. Testicular tissue superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), total antioxidant capacity (TAC) and DNA fragmentation levels were determined. Testicular tissue samples were examined by histopathological examination and terminal deoxynucleotidyl transferase dUTP nick end-labelling staining. The control, IR and IR + S groups had higher SOD values compared with the S group; SOD levels of the control and IR + S groups were higher than those of the IR group (P < 0.05). Further, MDA levels of the IR group were higher than those in the other three groups (P < 0.05). The IR group revealed lower TAC levels than the three groups (P < 0.05 for all). GSH levels of the IR group were significantly lower than those in the other three groups (P < 0.05 for all). In contrast, GSH levels of the IR + S group increased compared with those of the S group. The IR group had more DNA fragmentation than the control and S groups (P < 0.05). It is concluded that selenium possibly reduces oxidative stress and apoptosis caused by testicular IR injury in rats. The testicular protective effect of selenium appears to be mediated through its anti-apoptotic and antioxidative effects. However, selenium does not affect DNA fragmentation.

BACKGROUND: Lower urinary tract dysfunction (LUTD), an important cause of end stage renal disease (ESRD) in children, can adversely affect renal graft survival. We compared renal transplant patients with LUTD as primary renal disease to those without LUTD. METHODS: The data of 60 children who underwent renal transplantation (RTx) between 2000 and 2012 were retrospectively reviewed. All patients with LUTD were evaluated with urodynamic tests preoperatively; 15 patients required clean intermittent catheterization and 9 patients underwent augmentation cystoplasty before RTx. RESULTS: There were 25 children with LUTD. The mean follow-up for LUTD (+) and LUTD (-) groups were 63 (22-155) and 101 months (14-124), and graft survival were 76% for LUTD (+) and 80% for LUTD (-), respectively (P = .711). On the other hand, creatinine levels at last follow-up were significantly higher in the LUTD (+) group (1.3 ± 0.3 mg/dL vs 0.96 ± 0.57 mg/dL, P < .001). Infectious complications and postoperative urinary tract infection incidences were also higher in the LUTD (+) group (68% vs 25.7%, P = .002 and 60% vs 11.4%, P < .01). CONCLUSION: UTI is significantly higher after kidney transplantation in patients with LUTD. Despite the higher risk of UTI, renal transplantation can be performed safely in those patients with careful patient selection, preoperative management, and close postoperative follow-up. Restoration of good bladder function is the key factor in the success of kidney transplantation in those patients.
