Pyelorenal backflow in rabbits following clamping of the renal vein and artery: radiologic and microscopic investigation

Acta Radiologica: Diagnosis
H S ThomsenS Olsen

Abstract

Retrograde pyelography was carried out in rabbits during and following temporary clamping of either the renal artery and vein together or the main renal vein alone. Pyelosinous backflow was observed in all kidneys and pyelovenous backflow in 16 of the 18 kidneys, occurring at intrapelvic pressures between 50 and 100 mmHg. During simultaneous complete renal artery and vein occlusion intrarenal backflow occurred in all 3 kidneys examined while it was observed in 3 of 6 kidneys when the pyelography was performed 5 min after removal of the clamp. During complete renal vein occlusion filling with contrast medium of the central intrarenal veins occurred in all 3 kidneys but only in 3 of 6 kidneys examined after the clamp had been removed. Microscopically, pyelosinous backflow was explained by vital tears in the fornix of the pelvic cavity. Tears extending into the kidney parenchyma were only observed in kidneys with intrarenal backflow at pyelography.

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.

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.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

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.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
