Testicular contrast harmonic imaging to evaluate intratesticular perfusion alterations in patients with varicocele

Abstract

To determine whether changes in intratesticular microcirculation perfusion affect spermatogenesis in patients with left varicocele we performed testicular contrast harmonic imaging. A total of 90 patients with left varicocele (oligospermia in 50 and normozoospermia in 40) and 36 controls without varicocele (oligospermia in 16 and normozoospermia in 20) were enrolled in the study. Before contrast harmonic imaging all participants were evaluated by clinical examination, hormonal analysis, semen sample and scrotal ultrasound. We calculated contrast material arrival time in the arteriolar circulation (wash-in), time to peak in arterial circulation, arrival time in the venular circulation (washout) and mean transit time in each testis on contrast harmonic imaging. We found no difference in the distribution rate of varicocele grade in patients with vs without oligospermia. All contrast harmonic imaging parameters were significantly higher in patients with varicocele plus normozoospermia or oligospermia and controls. We found no significant differences in contrast harmonic imaging parameters in patients with lower varicocele grading with respect to the higher grades. In patients with varicocele we found a negative linear correlation b...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.
