Urachal remnants in asymptomatic children: gray-scale and color Doppler sonographic findings

Abstract

We undertook this study to evaluate the frequency of visualization and the sonographic appearances of urachal remnants (URs) in asymptomatic children. One hundred eighty-two children without any urachus-related symptoms underwent sonography of the prevesical region and urinary bladder with high-frequency transducers. A UR was visualized in 180 (99%) of the children. The URs had a mean length +/- standard deviation of 13 +/- 5 mm. Most of the URs were ovoid, and most demonstrated a moderate protrusion into the bladder cavity. The URs with a central echogenic area were larger than those without central echogenicity. In 36 (61%) of the 59 URs that were evaluated with color Doppler sonography, vascular signals were demonstrated within the lesion. The URs with internal vascular signals were significantly larger than those without internal vascular signals. The gray-scale and color Doppler sonographic characteristics of URs seem to be related to their size and their degree of involution rather than to the age of the child. We think that URs are present in almost all children. URs should be considered normal findings if they are asymptomatic and their length is not significantly greater than 22.5 mm, the 95th percentile in our study.

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.
