Litiasis en receptores de trasplante renal: revisión sistemática / Kidney stones in renal transplant recipients: A systematic review

Introducción La litiasis en el receptor del injerto renal puede ser una enfermedad peligrosa cuyo riesgo potencial es el deterioro de la función renal. Adquisición de la evidencia Se realizó una búsqueda sistemática de la literatura hasta febrero del 2023. El objetivo primario era evaluar la incidencia de litiasis en receptores de trasplante renal (TR). El secundario era valorar el momento de formación, la localización y la composición de la litiasis, las opciones de tratamiento disponibles y la incidencia de la pérdida del injerto. Síntesis de la evidencia Un total de 41 estudios no aleatorizados compuestos por 699 pacientes cumplieron los criterios de inclusión. La edad en el momento del diagnóstico de la litiasis oscilaba entre 29 y 53 años. La incidencia de urolitiasis se encontraba entre 0,1 y 6,3%, siendo diagnosticada generalmente a los 12 meses del TR. La mayoría de las litiasis detectadas se localizaron en los cálices o en la pelvis. La composición más frecuente fue la de oxalato cálcico. Se consideraron diferentes estrategias de tratamiento como vigilancia activa, ureteroscopia, abordaje percutáneo/combinado o cirugía abierta. Del total de pacientes, 15,73% fueron tratados con litotricia extracorpórea por ondas de choque (LEOCh) y 26,75% se sometieron a litotricia endoscópica o extracción quirúrgica. De estos sujetos, 18,03% se abordaron mediante nefrolitotomía percutánea, mientras que 3,14% se sometieron a un manejo combinado. Se realizó litotomía quirúrgica en 5,01% de los casos. La tasa libre de litiasis (TLL) global se situó en torno a 80%. Conclusiones La litiasis en el TR es una patología poco frecuente que suele diagnosticarse al año de la cirugía. Su localización más común son los cálices y la pelvis renal, y en la mayoría de los casos está compuesta de oxalato cálcico. Todos los tratamientos activos han demostrado resultados satisfactorios en términos de TLL, ... . (AU)

Introduction Lithiasis in renal graft recipients might be a dangerous condition with a potential risk of organ function impairment. Evidence acquisition A systematic literature search was conducted through February 2023. The primary objective was to assess the incidence of lithiasis in kidney transplant (KT) recipients. The secondary objective was to assess the timing of stone formation, localization and composition of stones, possible treatment options, and the incidence of graft loss. Evidence synthesis A total of 41 non-randomized studies comprising 699 patients met our inclusion criteria. The age at lithiasis diagnosis ranged between 29-53 years. Incidence of urolithiasis ranged from 0.1 to 6.3%, usually diagnosed after 12 months from KT. Most of the stones were diagnosed in the calyces or in the pelvis. Calcium oxalate composition was the most frequent. Different treatment strategies were considered, namely active surveillance, ureteroscopy, percutaneous/combined approach, or open surgery. 15.73% of patients were submitted to extracorporeal shock wave lithotripsy (ESWL), while 26.75% underwent endoscopic lithotripsy or stone extraction. 18.03% of patients underwent percutaneous nephrolithotomy whilst 3.14% to a combined approach. Surgical lithotomy was performed in 5.01% of the cases. Global stone-free rate was around 80%. Conclusions Lithiasis in kidney transplant is a rare condition usually diagnosed after one year after surgery and mostly located in the calyces and renal pelvis, more frequently of calcium oxalate composition. Each of the active treatments is associated with good results in terms of stone-free rate, thus the surgical technique should be chosen according to the patient's characteristics and surgeon preferences.

Trasplante renal abierto frente a trasplante renal asistido por robot: revisión sistemática del grupo de trabajo de trasplante renal de la sección de Jóvenes Urólogos Académicos (YAU) de la Asociación Europea de Urología (EAU) / Open versus robotic-assisted kidney transplantation: A systematic review by the European Association of Urology (EAU) – Young Academic Urologists (YAU) Kidney Transplant Working Group

Introducción En los últimos 20 años se ha evaluado el uso de la robótica en el campo del trasplante renal como abordaje miniinvasivo a esta población especialmente vulnerable. Al tratarse de un campo relativamente novedoso, pocos estudios han comparado el trasplante renal abierto (TRA) y el trasplante renal asistido por robot (TRAR), la mayoría en cohortes pequeñas. Para ampliar los conocimientos actuales, hemos querido reunir en este documento datos comparativos de TRA frente a TRAR en una revisión sistemática. Métodos Se realizó una revisión sistemática de acuerdo con la declaración de Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Se realizaron búsquedas en las bases de datos Medline, Embase y Cochrane para identificar todos los estudios que informaran sobre los resultados postoperatorios del TRAR frente al TRA. Resultados Un total de 2.136 pacientes de 13 estudios fueron incluidos. La mediana de edad de los receptores fue de 42,6 años (TRA: 43,5 años y TRAR: 40,3 años). La mediana de la tasa de trasplante renal preventivo fue de 27,1% (TRA: 23,3% y TRAR: 33,2%). La mediana del tiempo quirúrgico total y de recalentamiento fueron: 235 y 49 min, respectivamente, en la población TRA; 250 y 60 min en la población TRAR. Las tasas de complicaciones postoperatorias fueron: 26,2% en la población TRA y 17,8% en la población TRAR. Las tasas de retraso en la función del injerto fueron: 4,9% en la población TRA y 2,3 en la población TRAR. Los resultados funcionales a medio plazo y la supervivencia del paciente y del injerto fueron similares entre las poblaciones TRA y TRAR. Conclusión Esta revisión sistemática demostró que el TRAR puede asociarse a una menor incidencia de retraso en la función del injerto y de complicaciones quirúrgicas postoperatorias, así como a unos resultados funcionales a medio plazo y una supervivencia del paciente y del injerto similares, en comparación con el TRA para los pacientes con enfermedad renal terminal (AU)

Introduction In the last 20 years, robotic assisted procedures were evaluated in the field of kidney transplantation to provide a mini-invasive approach for this particularly fragile population. As a relatively new issue, few studies compared open kidney transplantation (OKT) and robotic-assisted kidney transplantation (RAKT), mostly in small cohorts. To improve current knowledge, we wanted here to gather comparative data of OKT vs RAKT in a systematic review. Methods A systematic review was performed according to preferred reporting items for systematic reviews and meta-analyses. Medline, Embase, and Cochrane databases were searched to identify all studies reporting post-operative outcomes of RAKT versus OKT. Results A total of 2,136 patients in 13 studies were included. Median recipient age was 42.6 years (OKT: 43.5 years and RAKT: 40.3 years). Median preemptive kidney transplantation rate was 27.1% (OKT: 23.3% and RAKT: 33.2%). Median total operative time and rewarming were respectively: 235 and 49 minutes in OKT population; 250 and 60 minutes in RAKT population.Post-operative complications rates were: 26.2% in OKT population and 17.8% in RAKT population. Delayed graft function rates were: 4.9% in OKT population and 2.3 in RAKT population. Mid-term functional outcomes, patient and graft survival were similar in OKT and RAKT population. Conclusion This systematic review showed that RAKT may be associated with a lower incidence of delayed graft function and post-operative surgical complications and similar mid-term functional outcomes, patient and graft survival, compared to OKT for end-stage renal disease patients (AU)

Trasplante renal en receptor pediátrico: consideraciones y estrategias de evaluación preoperatoria / Renal transplantation in pediatric recipients: Considerations and preoperative assessment strategies

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)

How to manage renal masses in kidney transplant recipients? A collaborative review by the EAU-YAU kidney transplantation and renal cancer working groups.

INTRODUCTION: Kidney transplant (KT) recipients have a four-times higher risk of renal malignancies compared to general population. As these patients frequently harbor bilateral or multifocal tumors, the management of renal masses is still under debate. OBJECTIVE: To explore the current management of the native kidney masses in KT patients. ACQUISITION OF EVIDENCE: We performed a literature search on MEDLINE/PubMed database. A number of 34 studies were included in the present review. SYNTHESIS OF EVIDENCE: In frail patients with renal masses below 3 cm, active surveillance is a feasible alternative. Nephron-sparing surgery is not justified for masses in the native kidney. Radical nephrectomy is the standard treatment for post-transplant renal tumors of the native kidneys in KT recipients, with laparoscopic techniques leading to significantly less perioperative complication rates as compared to the open approach. Concurrent bilateral native nephrectomy at the time of transplantation can be considered in patients with renal mass and polycystic kidney disease, especially if no residual urinary output is present. Patients with localized disease and successful radical nephrectomy do not require immunosuppression adjustment. In metastatic cases, mTOR agents can ensure efficient antitumoral response, while maintaining proper immunosuppression in order to protect the graft. CONCLUSIONS: Post-transplant renal cancer of the native kidneys is a frequent occurrence. Radical nephrectomy is most frequently performed for localized renal masses. A standardized and widely-approved screening strategy for malignancies of native renal units is yet to be implemented.

Medline, Embase, and Cochrane databases were searched to identify all studies reporting post-operative outcomes of RAKT versus OKT. RESULTS: A total of 2136 patients in 13 studies were included. Median recipient age was 42.6 years (OKT: 43.5 years and RAKT: 40.3 years). Median preemptive kidney transplantation rate was 27.1 % (OKT: 23.3 % and RAKT: 33.2 %). Median total operative time and rewarming were respectively: 235 and 49 min in OKT population; 250 and 60 min in RAKT population. Post-operative complications rates were: 26.2 % in OKT population and 17.8 % in RAKT population. Delayed graft function rates were: 4.9 % in OKT population and 2.3 in RAKT population. Mid-term functional outcomes, patient and graft survival were similar in OKT and RAKT population. CONCLUSION: This systematic review showed that RAKT may be associated with a lower incidence of delayed graft function and post-operative surgical complications and similar mid-term functional outcomes, patient and graft survival, compared to OKT for end-stage renal disease patients.

Ureteropelvic junction obstruction and renal calculi: Simultaneous treatment by robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde flexible ureteroscopy. Technique description and early outcomes.

BACKGROUND: Ureteropelvic junction obstruction (UPJO) and renal calculi are associated in 20 to 30% of cases and treatment is mandatory. The simultaneous surgical management is a therapeutic challenge that is still a source of controversy. We describe our technique combining robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde flexible ureteroscopy (fURS), assessing the feasibility of simultaneous treatment through an original technique. METHODS: This single centre series reports our initial experience with 12 patients. From January 2014 to September 2018, 12 patients underwent robot-assisted laparoscopic pyeloplasty with simultaneous fURS for UPJO and renal calculi. Mean age was 46 years (24-68). 92% had multiple renal stones and the mean cumulative stone diameter was 31,3mm. Robot-assisted pyeloplasty was performed with peroperative transcutaneous retrograde fURS through a ureteral access sheath introduced in an incision on the bassinet through a subcostal trocar. Stone extraction was performed using a basket. RESULTS: All patients underwent surgery successfully, achieving UPJ repair and complete stone extraction. Mean operating time was 92,5min (85-110). All reported Clavien-Dindo complications were grade 1. Non-contrast enhanced abdominal CT performed 1 month after surgery confirmed the absence of residual stones in all patients. Mean follow-up time was 10 months with no recurrence of UPJO. CONCLUSION: This small series confirms the feasibility with good surgical results of concomitant robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde fURS stone extraction. No major complications were observed. This technique is easily reproducible but requires 2 experienced urologists to be achieved in a contained operative time.

Psychological impact of the quarantine during the COVID-19 pandemic on the general European adult population: a systematic review of the evidence.

AIMS: Due to the coronavirus disease 2019 (COVID-19) different countries implemented quarantine measures to limit the spread of the virus. Many studies analysed the mental health consequences of restrictive confinement, some of which focused their attention on specific populations. The general public's mental health also requires significant attention, however. This study aimed to evaluate the effects of the COVID-19 quarantine on the general population's mental health in different European countries. Risk and protective factors associated with the psychological symptoms were analysed. METHODS: A systematic search was conducted on four electronic databases (PubMed, PsycINFO, Scopus and Google Scholar). Studies published up until 20th April 2021, and following eligibility criteria were selected for this review. One thousand three hundred thirty-five (1335) studies were screened, 105 of which were included. Via network analysis, the current study investigated the pathways that underlie possible risk factors for mental health outcomes. RESULTS: Anxiety, depression, distress and post-traumatic symptoms are frequently experienced during the COVID-19 quarantine and are often associated with changes in sleeping and eating habits. Some socio-demographic and COVID-19-related variables were found to be risk factors for an individual's wellbeing. In particular, being female, young, having a low income, being unemployed and having COVID-19-like symptoms or chronic disorders, were found to be the most common risk factors for mental health symptoms. CONCLUSIONS: The COVID-19 pandemic represented an unprecedented threat to mental health globally. In order to prevent psychological morbidity and offer support tailored to short-, medium- and long-term negative outcomes, it is essential to identify the direct and indirect psychosocial effects of the lockdown and quarantine measures, especially in certain vulnerable groups. In addition to measures to reduce the curve of viral transmission, policy makers should urgently take into consideration provisions to alleviate hazards to mental health.

Interviewing children: the impact of the COVID-19 quarantine on children's perceived psychological distress and changes in routine.

BACKGROUND: The COVID-19 outbreak has resulted in governments implementing disease containment measures such as school closures, social distancing, and home quarantine. To date, only a few studies have drawn attention to the psychological impact of lockdown on Italian children's mental health. The present study aimed to investigate the psychological distress (anxiety and mood symptoms) and perceived changes in routine among Italian primary and middle school students during the COVID-19 quarantine. METHODS: This interview study was performed between the 18th of May and 7th of June 2020: it involved a sample of 82 children and adolescents living in Milan (Italy), attending primary and middle school (aged 6 to 14 years), and their parents. RESULTS: Almost 30 % of the subjects reported having struggled to adjust to home learning. 36 responders completely changed their dietary habits during the lockdown: they were not eating the same amount of food and were consuming more junk food. Sleep habits were also affected by the lockdown measures: 28 % of the sample had difficulties sleeping and wished to sleep in their parents' bed. Concerning psychological distress, 64 (78 %) children and adolescents had anxiety symptoms; 43.9 % of the students reported significant mood symptoms. CONCLUSIONS: Children are not indifferent to the dramatic impact of the COVID-19 epidemic: our data confirm their difficulties in adapting to the quarantine measures. The effects of stress exposure may not manifest later on during the children's development, and, for this reason, it would be interesting to follow up on these participants to improve our understanding of how long these outcomes may last.

Explorando la perspectiva de los residentes sobre las modalidades y contenidos de aprendizaje inteligente para la educación virtual de urología: lección aprendida durante la pandemia de la COVID-19 / Exploring the Residents' Perspective on Smart learning Modalities and Contents for Virtual Urology Education: Lesson Learned During the COVID-19 Pandemic

OBJETIVO: La pandemia de la COVID-19 ha alterado sustancialmente las actividades de formación de los residentes. Si bien recientemente se han implementado nuevos programas de aprendizaje virtual, aún debe investigarse su utilidad desde la perspectiva de los aprendices de urología. MÉTODOS: Encuesta online transversal de 30 ítems, distribuida a través de Twitter, entre el 4 y el 18 de abril de 2020, con el objetivo de evaluar la perspectiva de los residentes de urología sobre las modalidades (videos pregrabados, seminarios web, podcasts y redes sociales [RRSS]) y contenidos (lecciones frontales, discusiones de casos clínicos, actualizaciones sobre guías y ensayos clínicos, videos quirúrgicos, clubes de revistas y seminarios sobre liderazgo y habilidades no técnicas) del aprendizaje inteligente (Smart learning). RESULTADOS: En total, 501 residentes de urología de 58 países completaron la encuesta. De estos, 78,4, 78,2, 56,9 y 51,9% consideraron los videos pregrabados, seminarios web interactivos, podcasts y RRSS, respectivamente, como modalidades de aprendizaje inteligente muy útiles. Los contenidos considerados como muy útiles por la mayor proporción de residentes fueron las actualizaciones de guías clínicas (84,8%) y videos quirúrgicos (81,0%). Además, más de la mitad de los residentes consideraron los seminarios de liderazgo y los de habilidades no técnicas (58,9 y 56,5%, respectivamente) como contenidos útiles para el aprendizaje inteligente. Las tres combinaciones preferidas de modalidad y contenido de aprendizaje inteligente fueron: videos quirúrgicos pregrabados, seminarios web interactivos sobre casos clínicos y videos pregrabados sobre guías. CONCLUSIÓN: Nuestro estudio proporciona la primera «visión global» de las modalidades y contenidos de aprendizaje inteligente que deben priorizarse con el objetivo de optimizar la educación virtual en urología. Aunque este estudio se llevó a cabo durante la pandemia de la COVID-19, nuestros hallazgos podrían tener un impacto aún mayor en el futuro

PURPOSE: The COVID-19 outbreak has substantially altered residents' training activities. While several new virtual learning programs have been recently implemented, the perspective of urology trainees regarding their usefulness still needs to be investigated. METHODS: A cross-sectional, 30-item, web-based Survey was conducted through Twitter from April 4th, 2020 to April 18th, 2020, aiming to evaluate the urology residents' perspective on smart learning (SL) modalities (pre-recorded videos, webinars, podcasts, and social media [SoMe]), and contents (frontal lessons, clinical case discussions, updates on Guidelines and on clinical trials, surgical videos, Journal Clubs, and seminars on leadership and non-technical skills). RESULTS: Overall, 501 urology residents from 58 countries completed the survey. Of these, 78.4, 78.2, 56.9 and 51.9% of them considered pre-recorded videos, interactive webinars, podcasts and SoMe highly useful modalities of smart learning, respectively. The contents considered as highly useful by the greatest proportion of residents were updates on guidelines (84.8%) and surgical videos (81.0%). In addition, 58.9 and 56.5% of responders deemed seminars on leadership and on non-technical skills highly useful smart learning contents. The three preferred combinations of smart learning modality and content were: pre-recorded surgical videos, interactive webinars on clinical cases, and pre-recorded videos on guidelines. CONCLUSION: Our study provides the first global «big picture» of the smart learning modalities and contents that should be prioritized to optimize virtual Urology education. While this survey was conducted during the COVID-19 outbreak, our findings might have even more impact in the future
