Calyceal diverticula in children: laparoscopic marsupialization is the optimal intervention.

Journal of Pediatric Urology

Abstract

Calyceal diverticula (CD) are abnormally dilated calyces caused by a narrowed infundibulum. Although rare, with incidence rates previously reported between 0.21% and 0.45%, CD pose diagnostic dilemmas in children as they mimic other cystic lesions of the kidney with different etiologies. Calyceal diverticula can become symptomatic if they become a locus for infections and stone formation, and the optimal treatment strategy is currently undefined. The aim of the study is to present a large series of consecutive cases of pediatric CD and investigate the authors' hypothesis that CDs are more common than previously reported, size of the lesion drives intervention, and laparoscopic ablation is the most effective intervention. The authors conducted an observational case-control survey by reviewing all cases of pediatric CD through a prospectively maintained database of renal cystic lesions at their institution between 2012 and 2018. They analyzed the clinical and radiological presentation and description of symptoms with particular emphasis on the outcomes of ureteroscopic or laparoscopic surgical interventions. Of 757 renal cysts evaluated in the pediatric urology clinics at the authors' institution, there were 43 (5%) cases of CD c...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.
