Predictors for abnormal voiding cystourethrography in pediatric patients undergoing renal transplant evaluation

Abstract

The role of pretransplant voiding cystourethrography (VCUG) in adults has been questioned owing to the low prevalence of abnormal findings. As there are no studies evaluating the relevance of VCUG in children and because vesicoureteral reflux (VUR) occurs with higher prevalence in children, we performed a retrospective cohort study to identify any predictors for abnormal VCUG. We reviewed 271 consecutive renal transplants performed between 1980 and 1997. By logistic regression, the etiology of end-stage renal disease (ESRD) and age at transplantation (Tx) were strong predictors of abnormal pretransplant VCUG findings in children. On multi-variate analysis, children with urologic etiologies of renal disease had an odds ratio (OR) of 16.5 (p < 0.0001) for abnormal VCUG as compared to children with non-urologic or acquired causes of ESRD. Similarly, children transplanted when younger than 8 yr of age had an OR of 3.0 (p = 0.0043) for having an abnormal VCUG when compared with older children. Finally, our analysis suggests that children with abnormal pretransplant VCUG findings, whether or not pretransplant surgical correction was performed, were over three-fold more likely to require post-transplant urologic surgery when compared ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
