Outcomes of kidney transplants in pediatric patients with the vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, limb abnormalities association

Kidney Transplantation in Congenital Abnormalities of Kidney and Urinary Tract (CAKUT)

Congenital anomalies of the kidney and urinary tract (CAKUT) are a common cause of chronic kidney disease in children. Most patients will reach end-stage renal function and dialysis or transplantation in childhood or early adulthood. Patients with CAKUT deserve a careful evaluation before a kidney transplant; detailed imaging and functional studies are necessary, particularly in the presence of lower urinary tract abnormalities, and surgical procedures are advisable in selected cases. A higher incidence of complications has been reported after a kidney transplant in CAKUT, mainly urinary tract infections. However, in the long term, the prognosis seems to be comparable to other kidney diseases. A large number of reports are available in the literature on medical and surgical management of patients with CAKUT before, during, and after a kidney transplant; almost all recommendations of surgical procedures before a kidney transplantation are based on retrospective not controlled studies or personal opinions; prospective controlled studies are needed. In this narrative, nonsystematic review, we report the results of recently published selected studies and underline questions that should be addressed in future guidelines.

Substantial incidence of bladder dysfunction in patients with VACTERL association: Implications for surveillance

VACTERL association is defined as the nonrandom co-occurrence of a minimum of three of the following six key components: Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities. Patients presenting with two components may also belong in the same spectrum. Additional components have been associated with VACTERL defects, including single umbilical artery, tethered spinal cord (TSC), and genital malformations. We observed a significant proportion of patients with bladder dysfunction (often called neurogenic bladder in the medical record) when reviewing a cohort of patients with VACTERL defects at our clinical center. Our finding calls attention to bladder dysfunction as an additional VACTERL phenotypic component. The prevalence of bladder dysfunction is greatest in those with genital anomalies, anorectal malformations, sacral dysplasia, renal anomalies, and TSC. We propose that patients with two or more VACTERL malformations be monitored for symptoms of bladder dysfunction if one or more of the identified risk factors are present until the achievement of urinary continence.

Recommendations for living donor kidney transplantation

This Guide for Living Donor Kidney Transplantation (LDKT) has been prepared with the sponsorship of the Spanish Society of Nephrology (SEN), the Spanish Transplant Society (SET), and the Spanish National Transplant Organization (ONT). It updates evidence to offer the best chronic renal failure treatment when a potential living donor is available. The core aim of this Guide is to supply clinicians who evaluate living donors and transplant recipients with the best decision-making tools, to optimise their outcomes. Moreover, the role of living donors in the current KT context should recover the level of importance it had until recently. To this end the new forms of incompatible HLA and/or ABO donation, as well as the paired donation which is possible in several hospitals with experience in LDKT, offer additional ways to treat renal patients with an incompatible donor. Good results in terms of patient and graft survival have expanded the range of circumstances under which living renal donors are accepted. Older donors are now accepted, as are others with factors that affect the decision, such as a borderline clinical history or alterations, which when evaluated may lead to an additional number of transplantations. This Guide does not forget that LDKT may lead to risk for the donor. Pre-donation evaluation has to centre on the problems which may arise over the short or long-term, and these have to be described to the potential donor so that they are able take them into account. Experience over recent years has led to progress in risk analysis, to protect donors' health. This aspect always has to be taken into account by LDKT programmes when evaluating potential donors. Finally, this Guide has been designed to aid decision-making, with recommendations and suggestions when uncertainties arise in pre-donation studies. Its overarching aim is to ensure that informed consent is based on high quality studies and information supplied to donors and recipients, offering the strongest possible guarantees.

An overview of esophageal atresia and tracheoesophageal fistula

ABSTRACT

Esophageal atresia and tracheoesophageal fistula are often-concomitant pathologies that primarily afflict neonates. The complications of these anomalies may lead to increased morbidity and mortality, and clinicians should be familiar with the diagnosis and management of these pathologies. Clinicians can improve patient outcomes by having a thorough understanding of the signs and symptoms, classification systems, diagnostic workup, and surgical intervention options for these patients. Early recognition and treatment are imperative in providing patients with the best opportunity for recovery.
